Lab Safety Quizzes Online & Trivia

The best answer is letter A. Usually at the start of a Chemistry class, the professor teaches the safety precautions to avoid accidents and what the students would do if they will encounter any. When someone accidentally broke a test tube and spilled its content on the table, it is best to use water and paper towels to clean what is spilled and put the broken test tube in the proper disposal container specified for sharp objects. Water is the best and safest liquid to be used especially on spills. Before doing an experiment, one must be aware of the location of all the safety equipment in the laboratory so if they happen to cause an accident, they can easily stop it while it is still manageable.

C is the best answer to this question. You can fan your hand over the substance so that the smell can start to reach your nose. This will allow you to get a whiff of the substance without sniffing it directly. It should be remembered that sniffing the substance. When you try to directly sniff the chemicals, there is a chance that you will be damaging your nasal passages and even your lungs. You need to stay safe and just get a whiff of the odor of the chemicals that you are dealing with. You can list down and describe the substance properly if needed in the report.

In my science class, we are never allowed to eat in the classroom so maybe change that.

You should never pipette by mouth. It can be too risky. Mouth pipetting is forbidden in the chemistry department. A pipette is a laboratory tool commonly used in chemistry, biology, and medicine to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of common pipetting techniques have been identified as potentially hazardous due to biochemical stress factors. Proper pipetting posture is the essential element in good work practices. It is a part of preparing experiments.

So you can follow the lab instructions clearly.

D. Caution your lab partners to avoid the area while you inform the teacher of the small accident.
