CCIL Laboratory Safety Protocols 5

Question 1

Which document must be completed immediately following a laboratory chemical spill that results in worker exposure?

Accepted Answer

An incident or accident report form

Answer

Any incident involving chemical exposure to workers must be documented immediately through an incident or accident report to ensure proper follow-up and regulatory compliance.

Question 2

The hierarchy of controls in laboratory safety lists which measure as MOST effective at reducing hazard exposure?

Accepted Answer

Elimination or substitution

Answer

Elimination or substitution of the hazard is always the most effective control because it removes the hazard entirely rather than managing exposure to it.

Question 3

In a CCIL-accredited environmental testing lab, chain of custody (COC) documentation primarily serves to:

Accepted Answer

Demonstrate sample integrity and traceability from collection to analysis

Answer

COC documentation establishes a traceable, unbroken record of sample possession and handling, which is critical for defensible data quality.

Question 4

Which action is required before performing maintenance on a laboratory instrument that uses high-voltage electricity?

Accepted Answer

Perform a lockout/tagout (LOTO) procedure to de-energize the equipment

Answer

Lockout/tagout procedures must be followed to ensure equipment is de-energized and cannot be accidentally restarted during maintenance.

Question 5

What is the maximum volume of flammable liquids typically permitted outside of a flammable storage cabinet in a standard laboratory work area?

Accepted Answer

5 gallons per laboratory

Answer

NFPA 45 and OSHA guidelines generally limit outside-cabinet flammable liquid storage to no more than 5 gallons in a laboratory work area.
