Concept explainers
Interpretation:
Two safety precautions while doing the experiment needs to be explained.
Concept introduction:
Precaution is an action taken in advance to protect against possible failure.

Answer to Problem 16STP
Two safety precautions while doing the experiment is given below:
- Wear safety goggles
- Wear lab coat and hand protection
Explanation of Solution
Two safety precautions while doing the experiment is given below:
3. Wear safety goggles: This helps to protect eyes from heating substances or dissecting, etc. Also, do not lift solutions or any other types of apparatus above eye level.
4. Wear lab coat and hand protection: This helps to protect clothes and hand from chemicals.
Wear safety goggles and wear lab coat are main two safety precautions.
