Safety in Science

Question 1 • *26-27 CFISD TX-Chemistry A CR

John is completing a lab in which he is using the corrosive base sodium hydroxide (NaOH). For this laboratory experiment, what types of safety precautions should he take? Check all that apply.

Answer
A
wear safety goggles
B
have his water bottle on the lab desk in case he gets thirsty
C
wear a lab coat
D
read any safety information, such as the SDS before he begins the experiment

Explanation

Sodium hydroxide is corrosive, so John should protect his eyes with safety goggles and his skin and clothing with a lab coat. He should also read the safety information, such as the SDS, before starting so he understands the hazards and safe handling steps. A water bottle should not be kept on the lab desk because food and drinks do not belong in the laboratory.
