Question 1

Which NIOSH-approved respirator class provides the highest level of respiratory protection during mold remediation in severely contaminated areas?

Accepted Answer

Supplied-air respirator (SAR)

Answer

A supplied-air respirator (SAR) provides the highest level of respiratory protection because it delivers clean air from an uncontaminated source rather than filtering ambient air.

Question 2

When performing mold remediation, what is the correct order for donning PPE?

Accepted Answer

Coveralls, respirator, eye protection, gloves

Answer

The correct donning sequence is coveralls first, then respirator, then eye protection, then gloves, ensuring that outer garments do not contaminate inner PPE.

Question 3

What is the primary purpose of a Tyvek coverall during mold remediation?

Accepted Answer

Protect skin and clothing from mold spore contact

Answer

Tyvek coveralls protect the worker's skin and personal clothing from direct contact with mold spores, preventing cross-contamination outside the work area.

Question 4

A worker with a beard wants to wear a half-face respirator for mold remediation. What should the supervisor advise?

Accepted Answer

Advise shaving or using a supplied-air hood/helmet respirator

Answer

Facial hair prevents a proper seal on tight-fitting respirators, so workers with beards must shave or use a loose-fitting supplied-air hood or helmet that does not require a face seal.

Question 5

During remediation, a worker's N95 respirator becomes visibly dirty and breathing resistance increases significantly. What is the correct action?

Accepted Answer

Replace the respirator immediately

Answer

An N95 respirator that is visibly dirty or shows significantly increased breathing resistance has reached end of service life and must be replaced immediately to maintain protection.
