Important Lab Safety Rules

Review the Lab Safety Rules

Before you set foot into the laboratory, make sure you know the important lab safety rules.

Safety Quiz Answers and Explanations

Regular glasses generally don’t protect the sides of your eyes and aren’t necessarily resistant to chemicals. Also, they aren’t usually impact-resistant. That being said, they offer more protection than wearing no eyewear at all.

Opening all the windows is a bad plan because it feeds the fire with oxygen . Similarly, adding water (H2O) feeds certain types of fires. Alternatively, water may cause a chemical reaction or spread chemicals. While using the correct type of fire extinguisher is a plan, definitely don’t run to get it. The best option is notifying the instructor.

Glassware that has cracks or chips often breaks during an experiment. Using items that aren’t clean contaminates the experiment, sometimes with dire consequences. Similarly, make sure glassware is dry because some chemicals don’t play nicely with water. Finally, if you don’t know how to use a piece of glassware, you increase the risk of an accident or ruined experiment.

Applying oil or lotion just traps the acid onto the skin. Soap and other bases do neutralize acids. However, the reaction between an acid and a base is exothermic . In other words, applying a base immediately increases the risk of adding a thermal burn to your chemical burn. First, rinse the acid with plenty of water. Then, neutralize any remaining acid with soapy water or a bit of baking soda or other weak base. Don’t use a strong base because it causes a chemical burn, just like the acid.

Labs have rules about how you dispose of chemicals and sharp objects. There are also rules about reporting accidents. So, the first action you take is warning your neighbors about the accident. Then, tell your instructor. Paper towels are not always the go-to means of mopping up a spill because some chemicals react with cellulose in paper and start a fire. How the spill gets cleaned up and what happens to the chemicals and the broken glass depends on the situation and your lab’s policies.

Most substances expand upon heating, so heating a sealed container risks an explosive outcome. Don’t handle hot containers using your hands. Never point the open end of a hot container toward yourself or another person because of the risk of releasing hot material. Even if no solid or liquid escapes, the vapor pressure sends fumes in that direction.

Immediately reporting injuries, even if they are minor, is important. Then, get first aid. Yes, injuring yourself in the lab is embarrassing, but don’t make light of it, cover it up, or delay treatment.

Your instructor needs to know whether or not you wear contacts. Contacts are fine in some labs, but they are a bad plan in a chemistry wet lab or a microbiology lab because they trap chemicals or microorganisms. Taking out your contacts before lab is a good option, but only if you have glasses and are used to wearing them. Walking around the lab blindly is not safe.

Never set hot glassware on a cold counter or douse it with cold water because it could shatter. Paper towels are not great insulators and may even catch fire. Touching glass to see if it’s cool isn’t smart, especially since you can use tongs and avoid the risk of a burn.

Pushing glass tubing through your hand leaves a nasty permanent scar. Breaking the tubing and slashing yourself isn’t much better. Work slowly and gently. Don’t force the tubing. If it won’t fit, the hole in the stopper might be too small. This is a surprisingly common accident!

The 10 Most Important Lab Safety Rules

The science lab is an inherently dangerous place, with fire hazards, dangerous chemicals, and risky procedures. No one wants to have an accident in the lab, so it's imperative to  follow lab safety rules . 

The Most Important Lab Safety Rule

Follow the instructions ! Whether it's listening to your instructor or lab supervisor or following a procedure in a book, it's critical to listen, pay attention, and be familiar with all the steps, from start to finish, before you begin. If you are unclear about any point or have questions, get them answered before starting, even if it's a question about a step later on in the protocol. Know how to use all of the lab equipment before you begin.

Why is this the most important rule? If you don't follow it:

  • You endanger yourself and others in the lab.
  • You could easily ruin your experiment.
  • You put the lab at risk of an accident, which could damage equipment as well as harm people.
  • You could get suspended (if you're a student) or fired (if you're a researcher).

Know the Location of Safety Equipment

In the event something goes wrong, it's important to know the location of the safety equipment and how to use it. It's a good idea to periodically check equipment to make sure it is in working order. For example, does water actually come out of the safety shower? Does the water in the eye wash look clean?

Not sure where safety equipment is located? Review lab safety signs and look for them before starting an experiment.

Dress for the Lab

Dress for the lab. This is a safety rule because your clothing is one of your best forms of protection against an accident. For any science lab, wear covered shoes, long pants, and keep your hair up so it can't fall into your experiment or a flame.

Make sure you wear protective gear , as needed. Basics include a lab coat and safety goggles. You may also need gloves, hearing protection, and other items, depending on the nature of the experiment.

Don't Eat or Drink in the Laboratory

Save your snacking for the office, not the lab. Don't eat or drink in the science laboratory. Don't store your food or beverages in the same refrigerator that contains experiments, chemicals, or cultures.

  • There is too much risk of contaminating your food. You could touch it with a hand that is coated with chemicals or pathogens or set it down on a lab bench that has residue from past experiments.
  • Having drinks in the lab risks your experiment, too. You could spill a drink on your research or lab notebook.
  • Eating and drinking in the lab is a form of distraction. If you are eating, you aren't concentrating on your work.
  • If you're used to drinking liquids in the lab, you might accidentally reach for and drink the wrong liquid. This is especially true if you did not label your glassware or used lab glassware as dishes.

Don't Taste or Sniff Chemicals

Not only should you not bring in food or drinks, but you shouldn't taste or smell chemicals or biological cultures already in the lab. Tasting or smelling some chemicals can be dangerous or even deadly. The best way to know what's in a container is to label it, so get in the habit of making a label for glassware before adding the chemical.

Don't Play Mad Scientist in the Laboratory

Another important safety rule is to act responsibly in the lab — don't play Mad Scientist, randomly mixing chemicals to see what happens. The result could be an explosion, fire, or release of toxic gases .

Similarly, the laboratory is not the place for horseplay. You could break glassware, annoy others, and potentially cause an accident.

Dispose of Lab Waste Properly

Matthias Tunger/Getty Images

One important laboratory safely rule is to know what to do with your experiment when it's over. Before you start an experiment, you should know what to do at the end. Don't leave your mess for the next person to clean up.

  • Are the chemicals safe to dump down the drain? If not, what do you do with them?
  • If you have biological cultures, is it safe to clean up with soap and water or do you need an autoclave to kill dangerous organisms?
  • Do you have broken glass or needles? Know the protocol for disposing of "sharps".

Know What to Do With Lab Accidents

 Getty Images/Oliver Sun Kim

Accidents happen, but you can do your best to prevent them and have a plan to follow when they occur. Most laboratories have a plan to follow in the event of an accident.

One particularly important safety rule is to tell a supervisor if and when an accident occurs . Don't lie about it or try to cover it up. If you get cut, exposed to a chemical, bitten by a lab animal, or spill something there could be consequences, and the danger isn't necessarily only to you. If you don't get care, sometimes you could expose others to a toxin or pathogen. Also, if you don't admit to an accident, you could get your lab in a lot of trouble.

Leave Experiments at the Lab

Getty Images/G Robert Bishop

It's important, for your safety and the safety of others, to leave your experiment at the lab. Don't take it home with you. You could have a spill or lose a specimen or have an accident. This is how science fiction movies start. In real life, you can hurt someone, cause a fire, or lose your lab privileges.

While you should leave lab experiments at the lab, if you want to do science at home, there are many safe science experiments you can try.

Don't Experiment on Yourself

The premise of many a science fiction movie starts with a scientist conducting an experiment on him or herself. However, you won't gain superpowers or discover the secret to eternal youth. More than likely, whatever you accomplish will be at great personal risk.

Science means using the scientific method . You need data on multiple subjects to draw conclusions, but using yourself as a subject and self experimenting is dangerous, not to mention bad science.

One of the unsafe actions taken in the picture is that Bob is touching broken glass. This is dangerous because it can break skin. He should instead use gloves to avoid contact, in addition to a broom and a dust pan to remove the glass. A second unsafe occurrence in the picture is that Joe is drinking an unknown liquid. Clear liquids are not always water, so there should be no eating or drinking of any kind in the laboratory to prevent health concerns. Sue’s hair is not in a ponytail, and it is likely that her hair will catch fire.

Three proper behaviors include Tina turning the test tube away from her while it’s over a flame, Carl is wearing goggles while he is working with a chemical, and John is cleaning the laboratory materials after use.

In order to properly clean the glass spill, Bob should first alert his teacher of the glass breakage. Then, he should put on gloves and sweep the glass into a dust pan. The surrounding area should be swept as well to ensure that all shards are removed from the floor.

It is important to ensure that all loose items are secured in the lab. If Sue doesn’t wish to have her hair cut short, she should ensure to wear a ponytail to lab. To ensure that she doesn’t forget, it would be useful for her to generally wear one on her wrist at all times.

Luke is following the rules because he is looking through the microscope with one eye open at his bench. Duke is not following the rules, and is at risk for becoming blind. When the light from the sun hits the microscope mirror, the light that is reflected will be damagingly bright.

Three things in the lab that should not be there include chips, a pair of scissors stuck in the socket, and a mirror. There should be no food in the lab, scissors conduct electricity and could cause someone to be electrocuted, and there should be no fooling around so Betty should leave her mirror at home.

Carl is doing it the correct way because he is clearly working on the given instructions and is wearing the proper protection equipment. On the other hand, Joe is not doing the experiment and is drinking the substance. In addition, Joe is not wearing safety goggles.

Ray and Tim will be asked to leave the classroom for engaging in horseplay. Not only are they hurting each other, they have the potential for hurting other classmates if the disruptive behavior continues.

Three items in the illustration that are there for the safety of the students in the lab include the eye wash station, the safety blanket, and the fire extinguisher.

Betty is not paying attention to the work that she should be doing and is being distracted by the mirror. This could lead to her getting hurt. This is made worse by the fact that she seems to be applying makeup; if chemicals had fallen on the makeup, she would then be applying them to her face, which could potentially cause a severe chemical burn.

How It Works

Who can help me write my essay?

At the end of the school year, students have no energy left to complete difficult homework assignments. In addition, inspiration is also lacking, so there are only a few options:

  • do not write a scientific work;
  • write it badly;
  • delegate these responsibilities to other people.

Most often, people choose the latter option, which is why companies have appeared on the Internet offering to take full responsibility.

When you visit the site, the managers clarify all the details in order to correctly design the article. They select a person who is well versed in the topic of the report and give him your task.

You will not be able to personally communicate with the writer who will do your work. This is done to ensure that all your personal data is confidential. The client, of course, can make edits, follow the writing of each section and take part in the correction, but it is impossible to communicate with the team.

Do not worry that you will not meet personally with the site team, because throughout the entire cooperation our managers will keep in touch with each client.
