REE CMLA Laboratory Safety & Procedures

Question 1

What is the primary purpose of wearing personal protective equipment (PPE) in a laboratory?

Accepted Answer

To prevent exposure to hazardous materials.

Answer

The primary purpose of wearing personal protective equipment (PPE) in a laboratory is to create a barrier between the worker and potential hazards. This prevents exposure to harmful chemicals, biological agents, and other dangerous materials, ensuring safety and minimizing risks of injury or contamination.

Question 2

How should you handle broken glassware in the laboratory?

Accepted Answer

Use a broom and dustpan to clean it up.

Answer

Broken glassware should always be handled with extreme caution to prevent cuts and injuries. Using a broom and dustpan allows you to safely collect the shards without direct hand contact. It should then be disposed of in a designated sharps container, not regular trash.

Question 3

What should you do if you spill a chemical in the laboratory?

Accepted Answer

Follow the appropriate cleanup procedure from the SDS.

Answer

If a chemical spill occurs, it is crucial to consult and follow the appropriate cleanup procedure outlined in the Safety Data Sheet (SDS) for that specific chemical. The SDS provides detailed information on hazards, protective measures, and proper spill response, ensuring safe and effective containment and disposal.

Question 4

How should you dispose of biological waste in a laboratory?

Accepted Answer

Dispose of it in biohazard containers.

Answer

Biological waste, which may contain infectious agents, must be disposed of in designated biohazard containers. This practice ensures proper segregation, treatment, and safe disposal, preventing the spread of pathogens and protecting laboratory personnel and the environment from contamination.

Question 5

Why is it important to know the location of emergency equipment in the laboratory?

Accepted Answer

So you can respond quickly in emergencies.

Answer

Knowing the location of emergency equipment, such as eyewash stations, safety showers, and fire extinguishers, is vital for responding quickly and effectively during an emergency. Rapid access to these tools can minimize injuries and mitigate hazardous situations, potentially saving lives.
