ASCS Risk Management & Mitigation 5

Question 1

Which term describes the process of transferring financial risk associated with an HVAC cleaning project to an insurance company or another party?

Accepted Answer

Risk transfer

Answer

Risk transfer shifts the financial burden of a potential loss to another party, most commonly through insurance or contractual indemnification clauses.

Question 2

A pre-cleaning inspection reveals damaged fiberglass duct liner inside a large commercial air handling unit. The PRIMARY risk associated with disturbing this material during cleaning is:

Accepted Answer

Release of respirable glass fibers into the airstream and work environment

Answer

Damaged fiberglass liner releases respirable glass fibers that can cause respiratory irritation and potential long-term lung damage if inhaled.

Question 3

When establishing a containment zone for HVAC cleaning in an occupied building, which measure BEST prevents pressure differentials from pushing contaminants into unaffected areas?

Accepted Answer

Placing a negative air machine inside the containment zone exhausting to the outside

Answer

A negative air machine creates lower pressure inside the containment zone, ensuring airflow moves inward rather than outward, preventing contaminant migration.

Question 4

After completing HVAC cleaning in a sensitive environment, which verification step BEST confirms that risk mitigation was effective?

Accepted Answer

Post-cleaning air quality testing and visual inspection of cleaned surfaces

Answer

Post-cleaning air quality testing and visual inspection objectively verify that contaminants have been removed and the environment is safe, not just that work was performed.

Question 5

Which scenario represents a 'near miss' in the context of HVAC cleaning risk management?

Accepted Answer

A worker slips on a wet floor but catches themselves on a ladder without injury

Answer

A near miss is an unplanned event that did not result in injury but had the potential to, and must be documented and investigated to prevent future incidents.
