Please read the featured article Lesson from Bhopal Gas Tragedy (1983-84) By Dr. Rhyddhi Chakraborty Programme Leader (Health and Social Care), London Churchill College, UK describes in detail the elements of the Bhopal Gas Tragedy

Union Carbide India Limited (UCIL)

In 1970, in the North adjacent to the slums and railway station, a pesticide plant was set up by Union Carbide India Limited (UCIL). From late 1977, the plant started manufacturing Sevin (Carbaryl) by importing primary raw materials, viz. alpha-naphtol and methyl isocyanate (MIC) in stainless steel drums from the Union Carbide's MIC plant in USA. However, from early 1980, the Bhopal plant itself started manufacturing MIC using the know-how and basic designs supplied by Union Carbide Corporation, USA (UCC). The Bhopal UCIL facility housed three underground 68,000 liters liquid MIC storage tanks: E610, E611, and E619 and were claimed to ensure all safety from leakage.

Time Line of Occupational Hazards of the Union Carbide India Limited Plant Leading Before the Disaster

• 1976: Local trade unions complained of pollution within the plant. • 1980: A worker was reported to have accidentally been splashed with phosgene while carrying out a regular maintenance job of the plant's pipes. • 1982 (January): A phosgene leak exposed 24 workers, all of whom were admitted to a hospital. Investigation revealed that none of the workers had been ordered to wear protective masks. • 1982 (February): An MIC leak affected 18 workers. • 1982 (August): A chemical engineer came into contact with liquid MIC, resulting in burns over 30 percent of his body. • 1982 (October): In attempting to stop the leak, the MIC supervisor suffered severe chemical burns and two other workers were severely exposed to the gases. • 1983-1984: There were leaks of MIC, chlorine, monomethylamine, phosgene, and carbon tetrachloride, sometimes in combination.

In early December 1984, most of the Bhopal plant's MIC related safety systems were not functioning and many valves and lines were in poor condition. In addition, several vent gas scrubbers had been out of service as well as the steam boiler, intended to clean the pipes. For the major maintenance work, the MIC production and Sevin were stalled in Bhopal plant since Oct. 22, 1984 and major regular maintenance was ordered to be done during the weekdays’ day shifts.

The Sevin plant, after having been shut down for some time, had been started up again during November but was still running at far below normal capacity. To make the pesticide, carbon tetrachloride is mixed with methyl isocyanate (MIC) and alpha-naphthol, a coffee-colored powder that smells like mothballs. The methyl isocyanate, or MIC, was stored in the three partly buried tanks, each with a 15,000-gallon capacity.

During the late evening hours of December 2, 1984, whilst trying to unclog, water was believed to have entered a side pipe and into Tank E610 containing 42 tons of MIC that had been there since late October. Introduction of water into the tank began a runaway exothermic reaction, which was accelerated by contaminants, high ambient temperatures and other factors, such as the presence of iron from corroding non-stainless steel pipelines.

A Three Hour Time Line of the Disaster

December 3, 1984 12:40 am: A worker, while investigating a leak, stood on a concrete slab above three large, partly buried storage tanks holding the chemical MIC. The slab suddenly began to vibrate beneath him and he witnessed at least a 6 inche thick crack on the slab and heard a loud hissing sound. As he prepared to escape from the leaking gas, he saw gas shoot out of a tall stack connected to the tank, forming a white cloud that drifted over the plant and toward nearby neighborhoods where thousands of residents were sleeping. In short span of time, the leak went out of control.

December 3, 1984 12:45 am: The workers were aware of the enormity of the accident. They began to panic both because of the choking fumes, they said, and because of their realization that things were out of control; the concrete over the tanks cracked as MIC turned from liquid to gas and shot out the stack, forming a white cloud. Part of it hung over the factory, the rest began to drift toward the sleeping neighborhoods nearby.

December 3, 1984 12:50 am: The public siren briefly sounded and was quickly turned off, as per company procedure meant to avoid alarming the public around the factory over tiny leaks. Workers, meanwhile, evacuated the UCIL plant. The control room operator then turned on the vent gas scrubber, a device designed to neutralize escaping toxic gas. The scrubber had been under maintenance; the flow meter indicated there was no caustic soda flowing into the device. It was not clear to him whether there was actually no caustic soda in the system or whether the meter was broken. Broken gauges were not unusual at the factory. In fact, the gas was not being neutralized but was shooting out the vent scrubber stack and settling over the plant. December 3, 1984 1: 15- 1:30 am: At Bhopal’s 1,200-bed Hamidia Hospital, the first patient with eye trouble reported. Within five minutes, there were a thousand patients. Calls to the UCIL plant by police were twice assured that "everything is OK", and on the last attempt made, "we don't know what has happened, sir". In the plant, meanwhile, MIC began to engulf the control room and the adjoining offices.

December 3, 1984 3:00 am: The factory manager, arrived at the plant and sent a man to tell the police about the accident because the phones were out of order. The police were not told earlier because the company management had an informal policy of not involving the local authorities in gas leaks. Meanwhile, people were dying by the hundreds outside the factory. Some died in their sleep. Others ran into the cloud, breathing in more and more gas and dropping dead in their tracks.

Immediate Consequences

With the lack of timely information exchange between Union Carbide India Limited (UCIL) and Bhopal authorities, the city's Hamidia Hospital was first told that the gas leak was suspected to be ammonia, then phosgene. They were then told that it was methyl isocyanate (MIC), which hospital staff had never heard of, had no antidote for, and received no immediate information about. The gas cloud, composed mainly of materials denser than air, stayed close to the ground and spread in the southeasterly direction affecting the nearby communities. Most city residents who were exposed to the MIC gas were first made aware of the leak by exposure to the gas itself.

Subsequent Actions

Formal statements were issued that air, water, vegetation and foodstuffs were safe, but warned not to consume fish. The number of children exposed to the gases was at least 200,000. Within weeks, the State Government established a number of hospitals, clinics and mobile units in the gas-affected area to treat the victims.

Legal proceedings involving UCC, the United States and Indian governments, local Bhopal authorities, and the disaster victims started immediately after the catastrophe. The Indian Government passed the Bhopal Gas Leak Act in March 1985, allowing the Government of India to act as the legal representative for victims of the disaster, leading to the beginning of legal proceedings.

Initial lawsuits were generated in the United States federal court system in April 1985. Eventually, in an out-of-court settlement reached in February 1989, Union Carbide agreed to pay US$470 million for damages caused in the Bhopal disaster. The amount was immediately paid.

Post-settlement activity

UCC chairman and CEO Warren Anderson was arrested and released on bail by the Madhya Pradesh Police in Bhopal on 7 December 1984. Anderson was taken to UCC's house after which he was released six hours later on $2,100 bail and flown out on a government plane. Anderson, eight other executives and two company affiliates with homicide charges were required to appear in Indian court.

In response, Union Carbide said the company is not under Indian jurisdiction. In 1991, the local Bhopal authorities charged Anderson, who had retired in 1986, with manslaughter, a crime that carries a maximum penalty of 10 years in prison. He was declared a fugitive from justice by the Chief Judicial Magistrate of Bhopal on 1 February 1992 for failing to appear at the court hearings in a culpable homicide case in which he was named the chief defendant. Orders were passed to the Government of India to press for an extradition from the United States. From 2014, Dow is a named respondent in a number of ongoing cases arising from Union Carbide’s business in Bhopal.

A US Federal class action litigation, Sahu v. Union Carbide and Warren Anderson, had been filed in 1999 under the U.S. Alien Torts Claims Act (ATCA), which provides for civil remedies for "crimes against humanity." It sought damages for personal injury, medical monitoring and injunctive relief in the form of clean-up of the drinking water supplies for residential areas near the Bhopal plant. The lawsuit was dismissed in 2012 and subsequent appeal denied. Anderson died in 2014.

Long-term Health Effects

A total of 36 wards were marked by the authorities as being "gas affected," affecting a population of 520,000. Of these, 200,000 were below 15 years of age, and 3,000 were pregnant women. The official immediate death toll was 2,259, and in 1991, 3,928 deaths had been officially certified. The government of Madhya Pradesh confirmed a total of 3,787 deaths related to the gas release. Later, the affected area was expanded to include 700,000 citizens. A government affidavit in 2006 stated the leak caused 558,125 injuries including 38,478 temporary partial injuries and approximately 3,900 severely and permanently disabling injuries.

Ethical Negligence

The Corporate Negligence Argument: This point of view argues that management (and to some extent, local government) underinvested in safety, which allowed for a dangerous working environment to develop.

Safety audits: In September 1984, an internal UCC report on the West Virginia plant in the USA revealed a number of defects and malfunctions. It warned that "a runaway reaction could occur in the MIC unit storage tanks, and that the planned response would not be timely or effective enough to prevent catastrophic failure of the tanks". This report was never forwarded to the Bhopal plant, although the main design was the same.

The Disgruntled Employee Sabotage Argument:  Now owned by Dow Chemical Company, Union Carbide maintains a website dedicated to the tragedy and claims that the incident was the result of sabotage, stating that sufficient safety systems were in place and operative to prevent the intrusion of water.

Bhopal Gas Tragedy : Causes, effects and aftermath

The Bhopal gas tragedy occurred at midnight of December 2nd- 3rd December 1984 at the Union Carbide India Ltd (UCIL) pesticide facility in Bhopal, Madhya Pradesh. This catastrophe affected around 500,000 people along with many animals. People who were exposed are still suffering as a result of the gas leak’s long-term health impacts. Chronic eye difficulties and respiratory problems were some issues due to it. Children who have been exposed have stunted growth and cognitive impairments.

Bhopal Gas Tragedy

Union Carbide was an American company that produced pesticides. MIC – methyl isocyanide, a dangerous poisonous gas began to leak at midnight on 2nd December 1984 from the Union Carbide factory. This MIC caused the Bhopal gas tragedy. The Bhopal gas tragedy was a fatal accident. It was one of the world’s worst industrial accidents. 

UCIL was a pesticide manufacturing plant that produced the insecticide carbaryl. Carbaryl was discovered by the American company Union Carbide Corporation, which owned a significant share in UCIL. As an intermediary, UCIL produced carbaryl using methyl isocyanate (MIC). Other techniques for producing the ultimate product are available, but they are more expensive. The very toxic chemical MIC is extremely dangerous to human health. Residents of Bhopal in the area of the pesticide plant began to feel irritated by the MIC and began fleeing the city.

Bhopal UCIL constructed three underground MIC storage tanks which were named E610, E611, and E619. On October 1984, E610 was not able to maintain its nitrogen gas pressure and so the liquid which is present inside the tank would not pump out, because of which 42 tons of MIC in E610 was wasted. The chemical in E610 was left unpumped as they were not able to re-establish its pressure, which later became responsible for Bhopal Gas Tragedy.

The main causes of Bhopal Gas Tragedy are as follows:

  • During the buildup to the spill, the plant’s safety mechanisms for the highly toxic MIC were not working. The alarm off tanks of the plant had not worked properly.
  • Many valves and lines were in disrepair, and many vent gas scrubbers were not working, as was the steam boiler that was supposed to clean the pipes.
  • The MIC was stored in three tanks, with tank E610 being the source of the leak. This tank should have held no more than 30 tonnes of MIC, according to safety regulations.
  • Water is believed to have entered the tank through a side pipe as technicians were attempting to clear it late that fatal night.
  • This resulted in an exothermic reaction in the tank, progressively raising the pressure until the gas was ejected through the atmosphere.

The main effects of the Bhopal Gas Tragedy are as follows:

  • Thousands had died as a result of choking, pulmonary edema, and reflexogenic circulatory collapse.
  • Neonatal death rates increased by 200 percent.
  • A huge number of animal carcasses have been discovered in the area, indicating the impact on flora and animals. The trees died after a few days. Food supplies have grown scarce due to the fear of contamination. 
  • Fishing was also prohibited.
  • In March 1985, the Indian government established the Bhopal Gas Leak Accident Act, giving it legal authority to represent all victims of the accident, whether they were in India or abroad.
  • At least 200,000 youngsters were exposed to the gas.
  • Hospitals were overcrowded, and there was no sufficient training for medical workers to deal with MIC exposure.

In the United States, UCC was sued in federal court. In one action, the court recommended that UCC pay between $5 million and $10 million to assist the victims. UCC agreed to pay a $5 million settlement. The Indian government, however, rejected this offer and claimed $3.3 billion. In 1989, UCC agreed to pay $470 million in damages and paid the cash immediately in an out-of-court settlement.

Warren Anderson, the CEO and Chairman of UCC was charged with manslaughter by Bhopal authorities in 1991. He refused to appear in court and the Bhopal court declared him a fugitive from justice in February 1992. Despite the central government’s efforts in the United States to extradite Anderson, nothing happened. Anderson died in 2014 without ever appearing in a court of law.

Bhopal Gas Tragedy continues to be an important warning sign for industrialization, for developing countries and in particular India, with human, environmental, and economic pitfalls. The economy of India is growing at a fast rate but at the cost of environmental health as well as public safety.

Metrics details

On December 3 1984, more than 40 tons of methyl isocyanate gas leaked from a pesticide plant in Bhopal, India, immediately killing at least 3,800 people and causing significant morbidity and premature death for many thousands more. The company involved in what became the worst industrial accident in history immediately tried to dissociate itself from legal responsibility. Eventually it reached a settlement with the Indian Government through mediation of that country's Supreme Court and accepted moral responsibility. It paid $470 million in compensation, a relatively small amount of based on significant underestimations of the long-term health consequences of exposure and the number of people exposed. The disaster indicated a need for enforceable international standards for environmental safety, preventative strategies to avoid similar accidents and industrial disaster preparedness.

Since the disaster, India has experienced rapid industrialization. While some positive changes in government policy and behavior of a few industries have taken place, major threats to the environment from rapid and poorly regulated industrial growth remain. Widespread environmental degradation with significant adverse human health consequences continues to occur throughout India.

Peer Review reports

December 2004 marked the twentieth anniversary of the massive toxic gas leak from Union Carbide Corporation's chemical plant in Bhopal in the state of Madhya Pradesh, India that killed more than 3,800 people. This review examines the health effects of exposure to the disaster, the legal response, the lessons learned and whether or not these are put into practice in India in terms of industrial development, environmental management and public health.

In the 1970s, the Indian government initiated policies to encourage foreign companies to invest in local industry. Union Carbide Corporation (UCC) was asked to build a plant for the manufacture of Sevin, a pesticide commonly used throughout Asia. As part of the deal, India's government insisted that a significant percentage of the investment come from local shareholders. The government itself had a 22% stake in the company's subsidiary, Union Carbide India Limited (UCIL) [ 1 ]. The company built the plant in Bhopal because of its central location and access to transport infrastructure. The specific site within the city was zoned for light industrial and commercial use, not for hazardous industry. The plant was initially approved only for formulation of pesticides from component chemicals, such as MIC imported from the parent company, in relatively small quantities. However, pressure from competition in the chemical industry led UCIL to implement "backward integration" – the manufacture of raw materials and intermediate products for formulation of the final product within one facility. This was inherently a more sophisticated and hazardous process [ 2 ].

In 1984, the plant was manufacturing Sevin at one quarter of its production capacity due to decreased demand for pesticides. Widespread crop failures and famine on the subcontinent in the 1980s led to increased indebtedness and decreased capital for farmers to invest in pesticides. Local managers were directed to close the plant and prepare it for sale in July 1984 due to decreased profitability [ 3 ]. When no ready buyer was found, UCIL made plans to dismantle key production units of the facility for shipment to another developing country. In the meantime, the facility continued to operate with safety equipment and procedures far below the standards found in its sister plant in Institute, West Virginia. The local government was aware of safety problems but was reticent to place heavy industrial safety and pollution control burdens on the struggling industry because it feared the economic effects of the loss of such a large employer [ 3 ].

At 11.00 PM on December 2 1984, while most of the one million residents of Bhopal slept, an operator at the plant noticed a small leak of methyl isocyanate (MIC) gas and increasing pressure inside a storage tank. The vent-gas scrubber, a safety device designer to neutralize toxic discharge from the MIC system, had been turned off three weeks prior [ 3 ]. Apparently a faulty valve had allowed one ton of water for cleaning internal pipes to mix with forty tons of MIC [ 1 ]. A 30 ton refrigeration unit that normally served as a safety component to cool the MIC storage tank had been drained of its coolant for use in another part of the plant [ 3 ]. Pressure and heat from the vigorous exothermic reaction in the tank continued to build. The gas flare safety system was out of action and had been for three months. At around 1.00 AM, December 3, loud rumbling reverberated around the plant as a safety valve gave way sending a plume of MIC gas into the early morning air [ 4 ]. Within hours, the streets of Bhopal were littered with human corpses and the carcasses of buffaloes, cows, dogs and birds. An estimated 3,800 people died immediately, mostly in the poor slum colony adjacent to the UCC plant [ 1 , 5 ]. Local hospitals were soon overwhelmed with the injured, a crisis further compounded by a lack of knowledge of exactly what gas was involved and what its effects were [ 1 ]. It became one of the worst chemical disasters in history and the name Bhopal became synonymous with industrial catastrophe [ 5 ].

Estimates of the number of people killed in the first few days by the plume from the UCC plant run as high as 10,000, with 15,000 to 20,000 premature deaths reportedly occurring in the subsequent two decades [ 6 ]. The Indian government reported that more than half a million people were exposed to the gas [ 7 ]. Several epidemiological studies conducted soon after the accident showed significant morbidity and increased mortality in the exposed population. Table 1 . summarizes early and late effects on health. These data are likely to under-represent the true extent of adverse health effects because many exposed individuals left Bhopal immediately following the disaster never to return and were therefore lost to follow-up [ 8 ].

Immediately after the disaster, UCC began attempts to dissociate itself from responsibility for the gas leak. Its principal tactic was to shift culpability to UCIL, stating the plant was wholly built and operated by the Indian subsidiary. It also fabricated scenarios involving sabotage by previously unknown Sikh extremist groups and disgruntled employees but this theory was impugned by numerous independent sources [ 1 ].

The toxic plume had barely cleared when, on December 7, the first multi-billion dollar lawsuit was filed by an American attorney in a U.S. court. This was the beginning of years of legal machinations in which the ethical implications of the tragedy and its affect on Bhopal's people were largely ignored. In March 1985, the Indian government enacted the Bhopal Gas Leak Disaster Act as a way of ensuring that claims arising from the accident would be dealt with speedily and equitably. The Act made the government the sole representative of the victims in legal proceedings both within and outside India. Eventually all cases were taken out of the U.S. legal system under the ruling of the presiding American judge and placed entirely under Indian jurisdiction much to the detriment of the injured parties.

In a settlement mediated by the Indian Supreme Court, UCC accepted moral responsibility and agreed to pay $470 million to the Indian government to be distributed to claimants as a full and final settlement. The figure was partly based on the disputed claim that only 3000 people died and 102,000 suffered permanent disabilities [ 9 ]. Upon announcing this settlement, shares of UCC rose $2 per share or 7% in value [ 1 ]. Had compensation in Bhopal been paid at the same rate that asbestosis victims where being awarded in US courts by defendant including UCC – which mined asbestos from 1963 to 1985 – the liability would have been greater than the $10 billion the company was worth and insured for in 1984 [ 10 ]. By the end of October 2003, according to the Bhopal Gas Tragedy Relief and Rehabilitation Department, compensation had been awarded to 554,895 people for injuries received and 15,310 survivors of those killed. The average amount to families of the dead was $2,200 [ 9 ].

At every turn, UCC has attempted to manipulate, obfuscate and withhold scientific data to the detriment of victims. Even to this date, the company has not stated exactly what was in the toxic cloud that enveloped the city on that December night [ 8 ]. When MIC is exposed to 200° heat, it forms degraded MIC that contains the more deadly hydrogen cyanide (HCN). There was clear evidence that the storage tank temperature did reach this level in the disaster. The cherry-red color of blood and viscera of some victims were characteristic of acute cyanide poisoning [ 11 ]. Moreover, many responded well to administration of sodium thiosulfate, an effective therapy for cyanide poisoning but not MIC exposure [ 11 ]. UCC initially recommended use of sodium thiosulfate but withdrew the statement later prompting suggestions that it attempted to cover up evidence of HCN in the gas leak. The presence of HCN was vigorously denied by UCC and was a point of conjecture among researchers [ 8 , 11 – 13 ].

As further insult, UCC discontinued operation at its Bhopal plant following the disaster but failed to clean up the industrial site completely. The plant continues to leak several toxic chemicals and heavy metals that have found their way into local aquifers. Dangerously contaminated water has now been added to the legacy left by the company for the people of Bhopal [ 1 , 14 ].

Lessons learned

The events in Bhopal revealed that expanding industrialization in developing countries without concurrent evolution in safety regulations could have catastrophic consequences [ 4 ]. The disaster demonstrated that seemingly local problems of industrial hazards and toxic contamination are often tied to global market dynamics. UCC's Sevin production plant was built in Madhya Pradesh not to avoid environmental regulations in the U.S. but to exploit the large and growing Indian pesticide market. However the manner in which the project was executed suggests the existence of a double standard for multinational corporations operating in developing countries [ 1 ]. Enforceable uniform international operating regulations for hazardous industries would have provided a mechanism for significantly improved in safety in Bhopal. Even without enforcement, international standards could provide norms for measuring performance of individual companies engaged in hazardous activities such as the manufacture of pesticides and other toxic chemicals in India [ 15 ]. National governments and international agencies should focus on widely applicable techniques for corporate responsibility and accident prevention as much in the developing world context as in advanced industrial nations [ 16 ]. Specifically, prevention should include risk reduction in plant location and design and safety legislation [ 17 ].

Local governments clearly cannot allow industrial facilities to be situated within urban areas, regardless of the evolution of land use over time. Industry and government need to bring proper financial support to local communities so they can provide medical and other necessary services to reduce morbidity, mortality and material loss in the case of industrial accidents.

Public health infrastructure was very weak in Bhopal in 1984. Tap water was available for only a few hours a day and was of very poor quality. With no functioning sewage system, untreated human waste was dumped into two nearby lakes, one a source of drinking water. The city had four major hospitals but there was a shortage of physicians and hospital beds. There was also no mass casualty emergency response system in place in the city [ 3 ]. Existing public health infrastructure needs to be taken into account when hazardous industries choose sites for manufacturing plants. Future management of industrial development requires that appropriate resources be devoted to advance planning before any disaster occurs [ 18 ]. Communities that do not possess infrastructure and technical expertise to respond adequately to such industrial accidents should not be chosen as sites for hazardous industry.

Following the events of December 3 1984 environmental awareness and activism in India increased significantly. The Environment Protection Act was passed in 1986, creating the Ministry of Environment and Forests (MoEF) and strengthening India's commitment to the environment. Under the new act, the MoEF was given overall responsibility for administering and enforcing environmental laws and policies. It established the importance of integrating environmental strategies into all industrial development plans for the country. However, despite greater government commitment to protect public health, forests, and wildlife, policies geared to developing the country's economy have taken precedence in the last 20 years [ 19 ].

India has undergone tremendous economic growth in the two decades since the Bhopal disaster. Gross domestic product (GDP) per capita has increased from $1,000 in 1984 to $2,900 in 2004 and it continues to grow at a rate of over 8% per year [ 20 ]. Rapid industrial development has contributed greatly to economic growth but there has been significant cost in environmental degradation and increased public health risks. Since abatement efforts consume a large portion of India's GDP, MoEF faces an uphill battle as it tries to fulfill its mandate of reducing industrial pollution [ 19 ]. Heavy reliance on coal-fired power plants and poor enforcement of vehicle emission laws have result from economic concerns taking precedence over environmental protection [ 19 ].

With the industrial growth since 1984, there has been an increase in small scale industries (SSIs) that are clustered about major urban areas in India. There are generally less stringent rules for the treatment of waste produced by SSIs due to less waste generation within each individual industry. This has allowed SSIs to dispose of untreated wastewater into drainage systems that flow directly into rivers. New Delhi's Yamuna River is illustrative. Dangerously high levels of heavy metals such as lead, cobalt, cadmium, chrome, nickel and zinc have been detected in this river which is a major supply of potable water to India's capital thus posing a potential health risk to the people living there and areas downstream [ 21 ].

Land pollution due to uncontrolled disposal of industrial solid and hazardous waste is also a problem throughout India. With rapid industrialization, the generation of industrial solid and hazardous waste has increased appreciably and the environmental impact is significant [ 22 ].

India relaxed its controls on foreign investment in order to accede to WTO rules and thereby attract an increasing flow of capital. In the process, a number of environmental regulations are being rolled back as growing foreign investments continue to roll in. The Indian experience is comparable to that of a number of developing countries that are experiencing the environmental impacts of structural adjustment. Exploitation and export of natural resources has accelerated on the subcontinent. Prohibitions against locating industrial facilities in ecologically sensitive zones have been eliminated while conservation zones are being stripped of their status so that pesticide, cement and bauxite mines can be built [ 23 ]. Heavy reliance on coal-fired power plants and poor enforcement of vehicle emission laws are other consequences of economic concerns taking precedence over environmental protection [ 19 ].

In March 2001, residents of Kodaikanal in southern India caught the Anglo-Dutch company, Unilever, red-handed when they discovered a dumpsite with toxic mercury laced waste from a thermometer factory run by the company's Indian subsidiary, Hindustan Lever. The 7.4 ton stockpile of mercury-laden glass was found in torn stacks spilling onto the ground in a scrap metal yard located near a school. In the fall of 2001, steel from the ruins of the World Trade Center was exported to India apparently without first being tested for contamination from asbestos and heavy metals present in the twin tower debris. Other examples of poor environmental stewardship and economic considerations taking precedence over public health concerns abound [ 24 ].

The Bhopal disaster could have changed the nature of the chemical industry and caused a reexamination of the necessity to produce such potentially harmful products in the first place. However the lessons of acute and chronic effects of exposure to pesticides and their precursors in Bhopal has not changed agricultural practice patterns. An estimated 3 million people per year suffer the consequences of pesticide poisoning with most exposure occurring in the agricultural developing world. It is reported to be the cause of at least 22,000 deaths in India each year. In the state of Kerala, significant mortality and morbidity have been reported following exposure to Endosulfan, a toxic pesticide whose use continued for 15 years after the events of Bhopal [ 25 ].

Aggressive marketing of asbestos continues in developing countries as a result of restrictions being placed on its use in developed nations due to the well-established link between asbestos products and respiratory diseases. India has become a major consumer, using around 100,000 tons of asbestos per year, 80% of which is imported with Canada being the largest overseas supplier. Mining, production and use of asbestos in India is very loosely regulated despite the health hazards. Reports have shown morbidity and mortality from asbestos related disease will continue in India without enforcement of a ban or significantly tighter controls [ 26 , 27 ].

UCC has shrunk to one sixth of its size since the Bhopal disaster in an effort to restructure and divest itself. By doing so, the company avoided a hostile takeover, placed a significant portion of UCC's assets out of legal reach of the victims and gave its shareholder and top executives bountiful profits [ 1 ]. The company still operates under the ownership of Dow Chemicals and still states on its website that the Bhopal disaster was "cause by deliberate sabotage". [ 28 ].

Some positive changes were seen following the Bhopal disaster. The British chemical company, ICI, whose Indian subsidiary manufactured pesticides, increased attention to health, safety and environmental issues following the events of December 1984. The subsidiary now spends 30–40% of their capital expenditures on environmental-related projects. However, they still do not adhere to standards as strict as their parent company in the UK. [ 24 ].

The US chemical giant DuPont learned its lesson of Bhopal in a different way. The company attempted for a decade to export a nylon plant from Richmond, VA to Goa, India. In its early negotiations with the Indian government, DuPont had sought and won a remarkable clause in its investment agreement that absolved it from all liabilities in case of an accident. But the people of Goa were not willing to acquiesce while an important ecological site was cleared for a heavy polluting industry. After nearly a decade of protesting by Goa's residents, DuPont was forced to scuttle plans there. Chennai was the next proposed site for the plastics plant. The state government there made significantly greater demand on DuPont for concessions on public health and environmental protection. Eventually, these plans were also aborted due to what the company called "financial concerns". [ 29 ].

The tragedy of Bhopal continues to be a warning sign at once ignored and heeded. Bhopal and its aftermath were a warning that the path to industrialization, for developing countries in general and India in particular, is fraught with human, environmental and economic perils. Some moves by the Indian government, including the formation of the MoEF, have served to offer some protection of the public's health from the harmful practices of local and multinational heavy industry and grassroots organizations that have also played a part in opposing rampant development. The Indian economy is growing at a tremendous rate but at significant cost in environmental health and public safety as large and small companies throughout the subcontinent continue to pollute. Far more remains to be done for public health in the context of industrialization to show that the lessons of the countless thousands dead in Bhopal have truly been heeded.

Bhopal Gas Tragedy – Case Study And Legal Consequences

Introduction:.

The industrial manufacturing sector is pivotal for the buoyancy of the Indian economy. Since this production sector extended its hands to facilitate economic sustainability, it has branched with diversified industries indulged and engaged in manufacturing automobiles, pieces of machinery, equipment, mental and electric appliance, mineral-extractions, so on. To utilize our demographic dividend, Indian is supposed to alleviate unemployment. The attainment of such an object necessitates the growth of the industrial sector, which is capable to create large-scale employment opportunities for youths. Consequently, millions of families will move out of poverty and fulfill their economic needs.

On the other hand, every single thing has its highlights and challenges. With having an eye on accomplishing economic and technological culmination, the human community is resting in a vain attempt to bring back or keep up the ecological footprint. The status quo industrial societies are pervaded with noxious or hazardous substances; indeed without the same nothing could be processed and produced. Negligence in treatment, usage, or disposal of such kinds of stuff has its ramifications in all walks of human life; even history tells us the same. India has witnessed countless industrial accidents; one of the notable incidents which have still deeply-rooted in the minds of Indians is the Bhopal gas leak tragedy.

Brief About the Incident:

To produce the pesticide named  Sevin  comprises the reagents, Methyl Isocyanate and Alpha Naphthol;   the American enterprises entitled the Union Cambridge Corporation has established its subsidiary in Bhopal as qua the central place with excellent transport links. Later, the established Indian subsidiary was named The Union Cambridge India Limited (UCIL) since the Indian public had owned the ownership, nearly 40.1% share in the corporation.

The incident happened on the night of December 2 to 3, 1984, when the forty tons of Methyl Isocyanate (MIC) was massively escaped from the Tank E106 at the UCC’s Indian subsidiary laid on at Bhopal. Since the plant has established in a crowded and inhabited area, within less than an hour, a great number of people and animals were befallen as victims and consequently died due to the toxicity of the leaked MIC. The estimated number of immediate death was 3500+, and the critical injury was 6+ lakh. Approximately, over the past decades since the incident, the death count has reached 20000. As per the Indian Council of Medical Research (ICMR) estimation, 62.58% of the Bhopal population had suffered from inhalational toxicity, withal having survivors might have experienced and developed bodily morbidities.

Concerning the treatment and Medicare, due to lack of information about the gas ebullition, the doctors did not play an efficient role. One of the causes for such a ramification is that the UCC’s refusal to disclose the precise proportion of the escaped gas by relying on the trade secrecy as a reasonable exemption.

Following the mishap, the victims have gone on an endless travel quest for justice, who have either lost their lives or sustained permanent disability. The two-fold question presented before the law for consideration is that, on what basis, the parameters for quantifying the liabilities of the corporation engaged in processing such a dangerous substance with nullified safety standards will be fixed? And the further aspect was how the government is going to tackle and prevent future damages by the installation of necessary safety protocols.

Legal Consequences of Bhopal Gas Tragedy:

The Bhopal Gas Leak Disaster (Processing of Claims) Act, 1985:

Soon after the man-disaster, noticing the multitude of the suits arising out of the incident, the Indian parliament has passed the Bhopal Gas Leak Disaster (Processing of Claims) Act on 29th March 1985. This Act confers the government to file suit for damages in place as a representative of the victims (either survived or deceased). For the purpose of effective enforcement of the Act, Section 9 authorizes the central government to frame a scheme; amounts to the introduction of the Bhopal Gas Leak Disaster (Registration and Processing of Claims) Scheme in 1985. The aforementioned government’s power to represent the affected party, both within and outside of India [1] , was predicated by the doctrine of  parens patriae.  However, the government has heavily criticized as, by enacting the Bhopal Act, it is attempting to smother the claimant from taking actions against the UCIL, since the government qua stakeholder at UCIL, is eligible to hold partially liable. Per contra, the government has managed to substantiate such enactment as, its  quo animo  is to secure the claims arising out of, or connected with, the Bhopal gas leak disaster, are dealt with speedily, effectively, equitably, and to the best advantage of the claimants and for matters incidental thereto . [2]

Does the Bhopal Act ultra vires the constitution:

Indeed, few allegations were brought before the Supreme Court challenging the constitutionality of the Bhopal Act in relation to Article 14 , 19 and 21. It was confronted that Sections 3, 4 and 11 of the Bhopal Act violated the right of Indian citizens under the Constitution of India to choose their own counsel, and alleging a conflict of interest by the Indian government, for it could not represent the victims because of its shared responsibility for the disaster by failing to enforce safety regulations. [3]  However, the Apex court rejected the appeal and upheld its constitutionality [4] .

Initial litigation:

Following the Act’s promulgation, in April 1985, the Indian government filed a suit against the UCC (the parent company of UCIL) in the Federal District Court of the southern district of New York, claiming 3.3 billion US dollars i.e. Rs. 3900 Crores. The skepticisms are that, why the Indian government does propose the American judiciary on behalf of the claimants, despite preferring the Indian judiciary system? Whether India has mistrusted its own judicature, or perhaps, it is strategically a ligation, which desires a significant sum of damages that the American judiciary could award? Nevertheless, the UCC fruitfully availed of the aforementioned issues under discussion and requested for the case dismissal on the grounds of  forum non-conveniens. Withal, they pleaded that, since the accident was taken place in India (Bhopal), it might be more convenient to be tried in India. 

Thus the litigation seeking both damages and punitive damages, invoking UCC’s liabilities such as absolute liability, strict liability, multinational enterprises liability theories, misrepresentation, negligence, and breach of warranty, was dismissed by the federal District Court after accepting the plea of UCC on May 12, 1986.

Rejection of settlement offers:

Since the parent company is responsible for the tortuous acts of the subsidiary company abroad, several efforts were taken by the UCC for outside court settlement but it went vain attempt after rejection by the Indian government. The negotiated settlement initiated by Union Carbide stood ready to provide 350 million dollars, which was accepted by the private lawyers representing the injured (both victims and the deceased) but dismissed by the Indian government.

Justice combats in Indian courts:

After getting rejected by the American Court, the suit pursued battle in India. In 1986 the Indian union brought this issue before the Bhopal District Court to recover 3.5 billion rupees damages. Subsequently, the same was reduced by 30% to 2.5 billion rupees by the high court of Madhya Pradesh. Later on, the Indian government appealed against the reduced interim award, rendered by the Madhya Pradesh high court before the apex court.

The five-judge bench heard the case, concerning the condition and status of victims, who were filled with hopelessness and experiencing the agony of despair. After four years of the chronicle’s worst industrial catastrophe, to end the wild goose chase and provide the immediate remedy, the Apex court rendered its judgment on 14th February 1989.

The matter of fact is that the people have lacked credibility since their collective thought was that the wrongdoer might get them self out of liabilities by invoking the exceptions of the doctrine of strict liability. Per contra, relying on the absolute liability Doctrine, the Apex Court [5]  upheld the liabilities of UCC and ordered them to pay the sum of 470 million USD (approximately Rs. 700 crores) as compensation.

Although the Indian government has brought the golden justice by fixing the liability of the company to pay $470 million, it is deemed to be a bad move qua the fixed damages is hardly 15% of the original claim for $3.3 million. Lucidly, it is not a sufficient sum to compensate for all the damage caused in relation to the tragedy.

Concerning the distribution of the awarded compensation, Rs. 1 lakh was provided to the deceased person’s family, Rs. 50000 for persons suffering lasting damage and Rs. 25,000 for the temporarily injured.

Criticisms on the settlement:

As mentioned, firstly, it was assailed for the total sum of the compensation amount, as being the full and final settlement of all claims, rights, and liabilities arising out of that disaster, [6] the fixed amount leads to inadequacy of sum to compensate. Secondly, in terms of the final payment, vide its judgment ‘ this settlement shall finally dispose of all past, present and future claims, causes of action and civil and criminal proceedings (of any nature whatsoever wherever pending) by all Indian citizens’. Comprehensibly, it quashed the criminal proceedings and concluded all the civil proceedings, further limited the liabilities for the claims which were filed later.

Considering the aforesaid criticisms,  in 1989, the Apex Court clubbed several petitions and revived the criminal proceedings, and held that if there is any shortage in the amount of compensation the state is bound to bridge the gap [7] .

In 1990, the Indian government sanctioned Rs. 258 crores funds to aid the victims for economic, social, environmental, and medical rehabilitation. Later in 2010, former UCIL chairman and other 6 Ex-employees were convicted for the term of 2 years with a 2000 USD fine for the offense of causing death by negligence.

Employed principle:

Absolute liability:.

The trite English principle of strict liability was laid by the case of Ryland v. Fletcher [8]  in 1868. The said principle states that the person will be held responsible for the leakage of any hazardous substance from his premises. Withal, it is noteworthy that, even though there is no negligence on his part, he will be held accountable for the act of keeping the dangerous things in his premises.  Vide  this case’s judgment; it elucidates the ingredients that are essential to invoke strict liability viz. there should be the possession of dangerous substances, it must be escaped from defendant’s premises, and it has been kept for non-natural use of the land. In addition, there are certain exceptions to this rule, which are as follows,

  • The fault of the plaintiff
  • Act of the third party
  • Consent of the party

Till the date of the  MC Mehta v Union of India case, [9] the rule of strict liability has governed the Indian judicature in relation to the matter of fact in issue. But then, the rule of absolute liability was introduced in the said oleum gas leak case, wherein the oleum gas was escaped from the fertilizer plant of Shriram foods and fertilizers enterprises. Since the enterprises had engaged in an ultra-hazardous activity, it is their absolute and non-delegable duty to safeguard others from getting injured out of their industrial process. In the case of any failure in discharging the obliged duties, the enterprises will be held liable to pay damages under tort law regardless of the cited strict liability exceptions. Indeed, the same was held in this oleum gas leak gas. Thus, in simple words, the concept of absolute liability is the strict liability without any exceptions, which means under no grounds a person could escape the liabilities.

Conclusion and Analysis:

After analyzing the given circumstance, it is pretty evident that the legislative lacunae lasted at the time of tragedy. Though the factories Act, 1948 was propounded even before the Bhopal catastrophe, it prioritizes the welfare of the workers employed in industries and factories and there is no first place law to deal with the concerned situation. This incident led to breakthroughs in the Indian legislature, the catena of legislations related to the environmental safeguard and determination of penalties were enacted. The status quo is that any similar incident that occurs now will be tried before the National Green tribunal and fall under the ambit of the Environmental protection Act, 1986. Even though, under the provisions of the Public liability Act, 1991, the injured could claim damages for the caused injury because of the leaked hazardous chemicals. In addition, the said Act of 1991 out on the basis of the concept of ‘no-fault liability.

Concerning the disposal of hazardous wastes from industry, we have Hazardous Wastes (Management, Handling, and Transboundary Movement) Rules, 2008, to govern the storage and disposal of such toxic substances with the aid of the pollution control board. Further, In the case of Foundation for Science, Technology and Natural Resource policy v. Union of India, [10] the Apex court upholds the constitutionality of the Hazardous wastes (Management & Handling) Rules, 1989, and the applicability of directions provided in the BASEL Convention. Prior to this, Chemical Accidents (Emergency Planning, Preparedness, and Response) Rules, 1996 was legislated to address gas leaks and to monitor the industries handling those deadly chemicals .

Thus, the aftermath of the Bhopal gas leak tragedy has substantially informed us about the importance of environmental protection and the concept of sustainable development . The wider array of Article 21 of the Indian constitution in relation to the r ight to a clean and healthy environment [11] has also been obtained only after the catena of judicial decisions interpreted the same. Besides, the Indian constitution prescribes the state as well as citizens to protect the environment under its Article, 39(b), 47, 48, 49, 48 A, and 51 A (g).

Even we have sufficient legislations to address the gas leaks issue; it is an absolute challenge to measure the injuries sustained by a person. However, the injured will receive damages in the light of law (Ubi jus ibi remidium). But then, how far it recompenses their loss? What about the people who lost their lives or happened to suffer the morbidities. Their psychological and physiological distresses are immeasurable. Hence, prevention is always better than cure by the mean, the government, industries, and citizens are obliged to take reasonable care because, ultimately, this is our environment.

The Bhopal gas tragedy is undoubtedly one of the worst industrial disasters in the history of mankind resulting in mortality of 2500-6000 and debilitating over 200 000 people. Inhabitants in the township were exposed to different degrees and there are more than 500 000 registered victims that survived the tragedy. Clinical studies have shown chronic illnesses such as pulmonary fibrosis, bronchial asthma, chronic obstructive pulmonary disease (COPD), emphysema, recurrent chest infections, keratopathy and corneal opacities in exposed cohorts. Survivors continue to experience higher incidence of reported health problems including febrile illnesses, respiratory, neurologic, psychiatric and ophthalmic symptoms. In-utero exposure to methyl isocyanate in the first trimester of pregnancy caused a persistent immune system hyper-responsiveness, which was in an evident way genetically linked with the organic exposure. Recent experimental studies have provided mechanistic understanding of methyl isocyanate exposure at a molecular level. Immunotoxic implications, toxico-genomic effect, inflammatory response, elicitation of mitochondrial oxidative stress, chromosomal and microsatellite instability have been studied comprehensively in cultured mammalian cells. Besides providing a framework for understanding potential mechanisms of toxicity of a host of other exposures, these studies may also uncover unique abnormalities thereby stimulating efforts to design newer and effective diagnostic and therapeutic strategies. The authors recommend long-term monitoring of the affected area and use of appropriate methods of investigation that include well-designed cohort studies, case-control studies for rare condition, characterization of personal exposure and accident analysis to determine the possible elements of the gas cloud.

What is Bhopal Gas Tragedy? (Detailed Case study)

The Bhopal gas tragedy also known as the Bhopal gas disaster, was a gas leak incident on the wintry night of 2 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India. It is considered to be the world’s worst industrial disaster.

Bhopal gas tragedy case study :

On 2nd December night, the night shift staff of the Union Carbide Factory, Bhopal, took around 11 p.m. There were three double-walled, partly buried S.S. tanks (No. 610, 611and 619) each of 60-tonne capacity and all containing the poisonous gas MIC (Methyl isocyanate) to be used to produce a deadly pesticide Carbaryl.

At 11-30, pm. workers in the plant realized that there was a MIC leak somewhere: their eyes began to tear. A few of them went to the MIC structure and noticed a drop of liquid with yellowish-white gas, about 50 feet off the ground. They told the supervisor who, however, decided to deal with the leak after the tea break which ended at 12:40 night. Meanwhile, the events had moved very fast.

The temperature of tank 610 had reached 25°C at the top of its scale and the pressure was increased twenty times rushing towards 40 psi at which the emergency safety valve was to open. Soon the pressure gauge showed 55 psi, the top of the scale, and the safety valve had opened releasing MIC With a loud hissing sound and tremendous heat. A white cloud drifting over the plant was moving towards the sleeping neighborhood.

The workers tried to operate the safety devices, but nothing seemed to work. The water jet failed to reach the top of the 120-foot stack from which MIC was escaping. The vent gas scrubber to neutralize the escaping gas did not work. The scrubber was under maintenance, the flow meter was not indicating the circulation of caustic soda whose concentration was also not known since October.

The flare tower to burn off the gas could not be ‘used because its piping was corroded and not replaced. The refrigeration system, of 30-tonne capacity, to keep the MIC in a liquid state at 0°C was closed down in June 1984 as an economy drive and the gas was at 15°-20°C Which was unsafe. For approximately two hours, the safety valve remained open releasing over 50,000 pounds of MIC (which might also contain Phosgene, Chloroform, Hydrogen cyanide. Carbon dioxide, etc.) out of 90,000 pounds stored in tank No. 610 at the time of the incident. Sometime between 1-30 to 2-30 am. the safety valve was reseated as the tank pressure went below 40 psi.

As per official records, the Bhopal gas leak killed 3,787 people. The figures were updated by the Madhya Pradesh government later as the immediate official estimate had put the death toll due to a gas leak from the Union Carbide factory at 2,259.

However, activists fighting for justice for Bhopal gas tragedy victims put the figures of death between 8,000 and 10,000. In an affidavit, submitted in 2006, the government said that the Bhopal gas leak caused 5,58,125 injuries that included approximately 3,900 severe and permanently disabling injuries.

Bhopal gas tragedy  Causes of the Accident :

(a) unsafe conditions of the bhopal gas tragedy  .

From the published press reports they seem to be:

  • The refrigeration system to keep the gas cool was closed for since long.
  • The vent gas scrubber was under-designed, not repaired, and not connected.
  • The corroded flare tower pipe was not replaced and was not connected.
  • The water curtain jests were under-designed to reach the maximum height.
  • All three tanks were filled in while one ought to have been kept empty to use as an emergency bypass.
  • The computerized pressure/temperature sensing system, a warning device to give the alarm and control the situation at the time of abnormal conditions was not installed.
  • The carbon steel valves were used instead of stainless steel and the valves ‘were notorious for leaking.
  • The instruments to check the valve leakage were not available.
  • The wind direction and velocity indicator were not installed to warn the people about leakage direction and severity.
  • The neighboring community was not told of the significance of the danger alarm and the dangers posed by the materials used in the plant.
  • Control instruments at the plant were faulty.
  • Maintenance and operational practices deteriorated.
  • Chemical reactors, piping, and valves were not purged, washed, and aired before maintenance operations.
  • The blind disc to disallow the water in the tank through the valve was missing.
  • Underqualified workers were running the factory.
  • People with chemical engineering backgrounds were replaced by less skilled operators.
  • The workers’ strength was reduced from 850 to 642 during the preceding two years and the operator’s duty relieving system was suspended.
  • The operating manual was grossly inadequate, not specifying all necessary emergency procedures to control abnormal conditions.
  • At the time of the accident, in the MIC control room, there was only one operator who found it virtually impossible to check the 70-odd panels, indicators, and controllers.
  • A design modification of the jumper line to interconnect the relief valve vent header and the process vent header was defective, as it allowed the water to go into the MIC tank.

(B) Unsafe Actions of Bhopal gas tragedy   :

  • The leak was not attended as soon as it was reported. Initial time passed in the tea break.
  • The first information about the five-fold pressure rise was dismissed in the belief that the pressure gauge could be faulty.
  • A newly recruited supervisor had asked a novice operator to clean a pipe and the blind disc was not inserted while doing so.
  • The public siren was put on around 1 am. nearly an hour after the gas leakage and that too for a few minutes.
  • The correct antidotes and medical treatments were not suggested to surrounding doctors. On the contrary confusion of MIC or Phosgene or Hydrogen cyanide was confounded.

(C) Unsafe Reactions of Bhopal gas tragedy  :

The above unsafe conditions and actions lead to the violent unsafe reaction. Different hypotheses have been expounded by Carbide’s scientists, Indian experts, and Dr. S. Varadrajan, who lead the investigations on behalf of the Government. According to him a small quantity of water reacted with Phosgene in the tank, mixed with MIC as an impurity to make it unstable. The Phosgene water reaction (hydrolysis) produced heat, CO2, and HCI.

The heat and HCI acted as the accelerators of the polymerization, additions, and degradation of MIC leading to a runaway reaction. According to others, the increased temperature of MIC (it vaporizes above 38°C) generated heat, pressure, and side reactions, higher than normal amounts of Chloroform in the stored MIC and an iron catalyst lead to the violent reaction. Because of the colder night of December, the escaped MIC settled down and traveled downward covering the sleeping surroundings with the blanket of death and damages.

What is Methyl isocyanate –

Methyl Isocyanate (MIC) is a chemical that is used in the manufacture of polyurethane foam, pesticides, and plastics. It is handled in liquid form which can be easily burned and explosive. It evaporates quickly in the air and has a strong odor. Its molecular formula is CH3NCO or C2H3NO and its molecular weight is approx. 57.05 g/mol. It is used in the production of pesticides, polyurethane foam, and plastics.

Remedial Measures of the Bhopal Gas Disaster :

All the 25 major causes of this accident stated above in (A) and (B) suggest remedial measures. To avoid repetition, all these contributing causes should be removed first and necessary steps should be taken to run the plant always safe and sound, with all the safety devices properly working. The working conditions must be improved and unsafe actions must be removed by proper policy, training, and education.

The Bhopal incident opened my eyes and gave many lessons to multinationals, developed countries, and developing countries.

Human life must be equally valued everywhere. No double standard for developed and developing countries. ‘Right to Know’ and ‘Obligation to Tell’ concepts are to be covered by the legislation. Training to staff, and workers, emergency procedures, highest standards for plant operation and maintenance and safety equipment, ‘worst case’ study and assessment, etc. were incorporated in 1987.

After the Bhopal gas leak incident :

Bhopal had a population of about 8.5 lakh back in 1984 and more than half of its population was coughing, complaining of itching in the eyes, skin and facing breathing problems. The gas caused internal hemorrhage, pneumonia, and death. The villages and slums in the neighboring areas of the factory were the worst affected.

The alarm system of the Union Carbide did not work for hours. No alarm was raised by the factory managers. Suddenly thousands of people started running to hospitals on the morning of December 3 with their complaints.

Unlike today, Bhopal in 1984 did not have too many hospitals. Two government hospitals could not have accommodated half of the population of the city. People were suffering, finding it difficult to breathe and confused. So were doctors, who did not immediately know the reasons for the sudden illness that afflicted every new rushing patient.

Patients complained of dizziness, breathlessness, skin irritation, and rashes, some others reported sudden blindness. Doctors of Bhopal had never faced a situation like this. They had no experience in dealing with industrial disasters.

Symptoms of methyl isocyanate exposure were not immediately known to them. And, the two hospitals reportedly treated around 50,000 patients in the first two days of the Bhopal gas leak. Officially, the government declared that the gas leakage was contained for eight hours, but the city is still finding it difficult to come out of its grip even 33 years later. So Bhopal incident was the world’s worst  industrial mishap .

A report based on an onsite study done by a twelve member fact-finding committee that found that while some wrong decisions were made by local plant managers, a large share of responsibility belongs to Union Carbide Corp. The report also found that many of the factors that caused or contributed to the disaster are common to many chemical manufacturers and industrial processes around the world, and are problems that can be controlled with proper safety procedures in place.

Jasanoff, S. (ED.). (1994) Learning From Disaster: Risk Management After Bhopal. Philadelphia: University of Pennsylvania Press. This is a collection of twelve papers that  not only discuss the Bhopal disaster as a case study, but also seeks to address wider questions about the transfer and control of hazardous technologies and the capacity of human societies to learn from failure.

Lepkowski, W. (1994). Ten years later: Bhopal.  Chemical & Engineering News  (December 19): 8-18. Details the events of the disaster, the confusing and often contradictory accounts of the facts of the event, and the ongoing suffering of the victims exposed to the gas. The article also discussed the “post-Bhopal” era of evolving openness and accountability in safety maters in the chemical industry, and how there is much further to go in this regard.

Paustenbach, D. J. (1987). Bhopal, Asbestos, and Love Canal . . . How They Should Affect Engineering Education. Technology and Society Magazine, IEEE, 6 (1), 9-15. doi: 10.1109/MTAS.1987.5010071. Over the past 15 years, society has come to expect that engineers, as practitioners and managers, be aware of those activities over which they have control, that could adversely affect the public's well-being. Specifically, due to incidents such as Love Canal, Bhopal, and Chernobyl, the public now recognizes that technology which is within the control of others can, if mishandled, jeopardize the health and well-being of thousands of innocent people. This paper suggests that schools of engineering have a responsibility to prepare engineers to meet these expectations and it recommends an approach to meet this challenge.

Reisch, M. 2004. Twenty Years After Bhopal .  Chemical and Engineering News  82 (no.23, June 7): 19-23. The author discusses the reactions of U.S. chemical industry leaders to the Bhopal disaster in developing the Responsible Care program, and the critics who say they have not done enough.

Union Carbide's approach to risk planning and management are examined in the context of the disaster. The factors that set the stage for the accident are also identified.

Varma, R., & Varma, D. R. (2005). The Bhopal Disaster of 1984. Bulletin of Science, Technology & Society, 25 (1), 37-45. doi: 10.1177/0270467604273822. The world's worst industrial disaster in Bhopal, India, happened because of inadequate maintenance by Union Carbide and poor monitoring by the Indian authorities. Malfunctioning safety measures, inappropriate location of the plant, and lack of information about the identity and toxicity of the gas worsened the effects of the accident on people and livestock. In this article, the authors present what happened and why and what lessons can be learned at this terrible cost.

Weiss, B., & Clarkson, T. W. (1986). Toxic Chemical Disasters and the Implications of Bhopal for Technology Transfer. The Milbank Quarterly, 64 (2), 216-240. doi: 10.2307/3349971. The author discusses how the disaster at Bhopal is a dramatic reminder of how the transfer of chemical technology must be accompanied by transfer of the corresponding infratechnology, toxicology. Only then can the process of technology transfer be managed with fewer risks, fewer costs, and fewer tragic surprises.

Wilson, G. T. (1986). Lessons of Bhopal for Production Managers. Engineering Management Review, IEEE, 14 (3), 33-43. doi: 10.1109/EMR.1986.4306222.

Policy Issues

Amnesty International. (2004). Clouds of Injustice: Bhopal Disaster 20 years on . Written on the 20 th anniversary of the disaster, this report gives a detailed account of the human rights impact of the leak and the contamination, corporate accountability for the leak, and the responsibility of the Indian state to hold the Union Carbide Corporation accountable and to ensure victims receive compensation and rehabilitation. The report aims to expose the failure of Union Carbide Corporation/Dow and the Indian government to comply with their respective obligations to prevent the gas leak and address its consequences, as well as to adequately address their human rights responsibilities.

Broughton, Edward. (2005) The Bhopal Disaster and its Aftermath: A review. Environmental Health. 4(6): doi: 10.1186/1476-069X-4-6. This article gives an excellent summary of the worst industrial accident in history, Union Carbide’s attempt to avoid legal responsibility and their final settlement with the Indian government. The authors stress the need for enforceable international standards for environmental safety, preventative strategies to avoid similar accidents, and industrial disaster preparedness.

 Chiles, J. R. (2002).  Inviting Disaster: Lessons from the Edge of Technology.  Harper Business: New York. Covering a number of disasters including Bhopal, the author looks at how even the most “smart” technological systems are prone to failure and how these catastrophes occur, their outcomes, and potential ways of avoiding these failures in the future.

Dhillon, K. (2002). Bhopal's Deadliest Night--A Case Study. Australian Journal of Professional and Applied Ethics, 4 (1), 1-29. After exploring the catastrophic effects of the Bhopal disaster, the author discusses how the adoption of a precautionary approach to industrialization in developing communities could have prevented or at least minimized the fatalities, arising from the breakdown of the Carbide facility,. Globalization needs to be viewed in totality as a complex and multidimensional concept and not a monolithic process. Any hasty judgments about globalization 'per se', therefore, can be grossly irrelevant. It is a system of interacting forces--economic, political, cultural, et al.--intersecting with the unique features of the local milieu. In some cases, of which Bhopal is a spectacularly tragic example, the consequences of such interactions can be catastrophic.

Fortun, K. (1998). THE BHOPAL DISASTER: Advocacy and Expertise. Science as Culture, 7 (2), 193. This article discusses the Bhopal Group for Information and Action (BGIA), a group of Indian activists working to support victims of the Bhopal disaster in India.

Jasanoff, S. (2007). Bhopal's Trials of Knowledge and Ignorance. ISIS: Journal of the History of Science in Society, 98 (2), 344-350. The disastrous gas leak at a Union Carbide plant in Bhopal, India, in December 1984 displayed the law's tragic inability to cope with the consequences of technological globalization. This essay describes the protracted efforts of the gas victims to obtain relief from courts in India and the United States and the reasons why the settlement of their legal claims did not satisfy their demands for justice.

Jayaraman, N. (2009). Wrong Questions. Wrong Answers. Global Social Policy, 9 (3), 318-321. The article discusses the lessons which could have been learned after the Union Carbide Corp. factory disaster in Bhopal, India. It mentions that the aftermath of the disaster teaches about basic respect for life, the importance of life over profits and preparation for any disaster to happen in the future.

Morehouse, Ward and M. Arun Subramaniam. (1986) The Bhopal Tragedy: What Really Happened and What it Means for American Workers and Communities at Risk. Preliminary Report for the Citizens Commission on Bhopal. New York: Council on International and Public Affairs. A report for the Citizens Commission on Bhopal, this was the first book-length account of the Bhopal tragedy and its implications for American workers and communities exposed to similar risks. It addresses the key question of who was responsible for this catastrophic accident and probes the health and environmental, impact of the disaster.

Ravi Rajan, S. (2002). Disaster, Development and Governance: Reflections on the 'Lessons' of Bhopal. Environmental Values, 11 (3), 369-394. The paper firstly uses the case study of the Bhopal gas disaster to understand why many scholars and activists seek alternatives to 'big' development. Secondly, it critically examines the claims that have been made in this regard in the literature in political ecology, science and technology studies and environmental governance, and in doing so, articulates a framework of questions for the next generation of research and advocacy.

Shrivastava, P. (1996). Long-term recovery from the Bhopal Crisis. In J. Mitchell, Ed.,  The long road to recovery: Community responses to industrial disaster.  United Nations University Press. This chapter begins with a brief description of the Bhopal crisis and then discusses causes of the crisis in terms of antecedent conditions and accident-related failures. The author then describes a multiple perspectives framework for understanding crisis recovery issues that looks at the perspectives of the primary stake-holders - the community and its victims, Union Carbide Corporation, and the Government of India. The final section includes speculations about long-term recovery from crisis and examines policy implications.

Trotter, R. C., Day, S. G., &  Love, A. E. (1989). Bhopal, India, and Union Carbide: the second tragedy.   Journal of Business Ethics, 8 (6), 439-454. This article examines the legal, ethical, and public policy issues involved in the Bhopal disaster that caused the death of over 3,000 people and injured thousands more. The paper begins with the results surrounding the accident, and then discusses an international situation audit examining internal strengths and weakness, and external opportunities and threats faced by Union Carbide.  The author also discusses the second tragedy of Bhopal, the tragic failure of the international legal system to adequately and timely compensate the victims of the accident.

Waldman, Amy. (2002) Bhopal Seethes, Pained and Poor 18 Years Later .   New York Times , September 21, 2002. This newspaper article discusses how eighteen years after the accident, the CEO of Union Carbide has still not been brought up on charges and victims have received little or no compensation for the injuries suffered from the disaster.
