How to Apply Safety Rules and Techniques for the Chemistry
Laboratory
This exercise explores some basic safety and first aid rules and the reason for their
existence. In addition, you will also devise some techniques for doing some experiments.
Use complete sentences to answer the questions below.
PART A
1. Describe some clothing and accessories that would be inappropriate in the lab.
Explain why they should NOT be worn.

d. Eyewash
e. Shower
4. Explain what should be done if someone happens to:
a. Receive a burn
b. Receive a cut
c. Pour acid or base on their body or clothing
d. Cause a fire in the lab
e. Get a chemical in his/her eyes
f. Spill a large quantity of chemical liquid in the lab
