Which NIOSH-approved respirator class provides the highest level of respiratory protection during mold remediation in severely contaminated areas?
Answer: Supplied-air respirator (SAR)
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.
When performing mold remediation, what is the correct order for donning PPE?
Answer: Coveralls, respirator, eye protection, gloves
The correct donning sequence is coveralls first, then respirator, then eye protection, then gloves, ensuring that outer garments do not contaminate inner PPE.
What is the primary purpose of a Tyvek coverall during mold remediation?
Answer: Protect skin and clothing from mold spore contact
Tyvek coveralls protect the worker's skin and personal clothing from direct contact with mold spores, preventing cross-contamination outside the work area.
A worker with a beard wants to wear a half-face respirator for mold remediation. What should the supervisor advise?
Answer: Advise shaving or using a supplied-air hood/helmet respirator
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.
During remediation, a worker's N95 respirator becomes visibly dirty and breathing resistance increases significantly. What is the correct action?
Answer: Replace the respirator immediately
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.
Which type of glove material is recommended when mold remediation also involves handling bleach-based cleaning solutions?
Answer: Nitrile gloves
Nitrile gloves provide excellent resistance to bleach and other disinfectant chemicals while also protecting against mold spore contact, making them the preferred choice.
What eye protection is required when using biocidal sprays during mold remediation?
Answer: Unvented chemical splash goggles or face shield
Unvented chemical splash goggles or a face shield are required when using biocidal sprays to prevent chemical splashes from reaching the eyes through side or vent openings.
