As a responsible laboratory professional, it’s essential to be aware of the potential hazards and take necessary precautions to ensure a safe working environment. The following lab safety scenarios worksheet answer key provides guidance on how to respond to various situations that may arise in a laboratory setting.

Scenario 1: Spill Response

You accidentally knock over a beaker containing a chemical solution, spilling it onto the countertop. What do you do?

• Answer: Immediately alert others in the lab and put on gloves and goggles. Contain the spill by placing absorbent paper or a spill pad around the area. Neutralize the spill with a suitable chemical, if necessary, and then clean up the spill with soap and water. Dispose of the contaminated materials properly.

• ⚠️ Note: Always handle chemicals with care, and be prepared for unexpected spills by having a spill response plan in place.

Scenario 2: Fire Safety

You notice a fire burning in the lab trash can. What do you do?

• Answer: Activate the fire alarm and alert others in the lab. Evacuate the area and close all doors behind you to contain the fire. Use a fire extinguisher rated for the type of fire (e.g., Class B for flammable liquids) if you are trained to do so and the fire is small. Never fight a fire that is too large or spreading quickly.
