'Possible' indicates the event might happen under some circumstances but is not the most likely outcome in routine operations.

Question 3

Before beginning HVAC cleaning in a laboratory with hazardous chemical storage, which risk management step is MOST critical?

Accepted Answer

Reviewing the Safety Data Sheets (SDS) for chemicals stored in the area

Answer

SDS review identifies chemical hazards, proper PPE requirements, and emergency response procedures before work begins in hazardous environments.

Question 4

Which action constitutes an administrative control in the hierarchy of HVAC cleaning risk controls?

Accepted Answer

Establishing a written confined space entry permit procedure

Answer

Administrative controls include written procedures, permits, training requirements, and work schedules that change how work is performed rather than the physical environment.

Question 5
