ASCS Risk Management & Mitigation 2

Question 1

A technician discovers standing water inside a supply air duct during an inspection. What is the MOST appropriate initial risk mitigation step?

Accepted Answer

Document the finding, identify the moisture source, and recommend remediation before cleaning

Answer

Standing water indicates an active moisture intrusion problem that must be sourced and corrected before cleaning to prevent recontamination and mold growth.

Question 2

Which type of risk assessment tool uses a grid to plot the probability of a hazard against its potential severity?

Accepted Answer

Risk matrix

Answer

A risk matrix plots likelihood versus consequence to help prioritize which risks require immediate mitigation action.

Question 3

When cleaning HVAC systems in a hospital, which patient area classification presents the HIGHEST biological risk requiring the most stringent containment?

Accepted Answer

Operating rooms and immunocompromised patient suites

Answer

Operating rooms and areas housing immunocompromised patients are the most vulnerable environments, requiring maximum containment to prevent airborne pathogen exposure.

Question 4

A risk residual is best defined as:

Accepted Answer

The level of risk that remains after all mitigation measures have been implemented

Answer

Residual risk is what remains after controls are in place, and it must be deemed acceptable before work proceeds.

Question 5

An ASCS technician notices significant visible mold inside a commercial air handling unit. Under NADCA standards, what is the correct course of action?

Accepted Answer

Stop work, notify the client, and recommend a licensed mold remediation contractor

Answer

NADCA ACR 2021 requires that visible mold contamination be referred to a qualified remediation contractor before HVAC cleaning proceeds.
