Asbestos accreditation exam (AHERA/MAP Inspector and Abatement Worker)
Respiratory protection and PPE: practice questions
Our Asbestos Inspector / Worker bank has 22 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
Why does facial hair matter for tight-fitting respirators?
- It makes the mask warmer but does not affect fit
- It has no effect on respirator protection at all
- It filters fibers out of the air like a HEPA filter
- It can break the seal between the face and facepiece
Show the answer
D. It can break the seal between the face and facepiece — 1910.134(g)(1)(i)(A) prohibits facial hair between the sealing surface and the face or interfering with valves.
Question 2
A worker tears a suit while working in the regulated area. What does OSHA require?
- Cover it with duct tape tomorrow
- Finish the shift, then replace it
- Report it at the weekly meeting
- Mend it or replace it immediately
Show the answer
D. Mend it or replace it immediately — 1926.1101(i)(4)(ii) requires rips and tears to be mended or the suit replaced immediately.
Question 3
Grade D breathing air must have an oxygen content of:
- At least 25 percent
- 16 to 19.5 percent
- 21 to 30 percent
- 19.5 to 23.5 percent
Show the answer
D. 19.5 to 23.5 percent — 1910.134(i)(1)(ii)(A) specifies oxygen content of 19.5-23.5%.
Question 4
An oxygen-deficient atmosphere under 1910.134 has oxygen below:
- 19.5 percent
- 23.5 percent
- 16 percent

A. 19.5 percent — 1910.134(b) defines oxygen deficient as below 19.5% by volume.
Question 5
How often must a tight-fitting respirator be fit-tested under 29 CFR 1910.134?
- Only once, when the worker is first hired
- Before first use and at least annually
- Every 3 years, or when the worker asks
- Every 5 years, at each refresher course
