CCIL Laboratory Safety Protocols 3

Question 1

A laboratory technician notices a strong solvent odor while working at the bench. The FIRST corrective action should be to:

Accepted Answer

Move work into the fume hood immediately

Answer

Work involving volatile solvents generating detectable odors must be moved into a functioning fume hood to prevent inhalation exposure.

Question 2

Under laboratory waste management protocols, empty containers that held acutely hazardous chemicals must be:

Accepted Answer

Triple-rinsed and managed as hazardous waste

Answer

Empty containers of acutely hazardous materials require triple-rinsing and must still be managed as hazardous waste per regulatory standards.

Question 3

What minimum face velocity (in feet per minute) is generally required for a properly functioning chemical fume hood?

Accepted Answer

60–100 fpm

Answer

A face velocity of 60–100 fpm is the generally accepted range to ensure adequate containment in a chemical fume hood.

Question 4

Which of the following is an example of an administrative control for laboratory chemical hazards?

Accepted Answer

Implementing mandatory buddy-system procedures

Answer

Administrative controls include work practices and procedural changes such as buddy systems, whereas engineering controls and PPE are separate hierarchy categories.

Question 5

When are laboratory workers required to remove personal protective equipment (PPE) such as gloves before leaving the lab?

Accepted Answer

Before exiting into any common area or corridor

Answer

PPE must be removed before leaving the laboratory to prevent spreading contamination into common areas.
