- Toxic contaminants, then flammable gases, then oxygen level
- Oxygen level, then flammable gases, then toxic contaminants (Correct answer)
- Flammable gases, then oxygen level, then toxic contaminants

Correct answer: Oxygen level, then flammable gases, then toxic contaminants
OSHA specifies testing in the order of oxygen content first, flammable gases/vapors second, and potential toxic air contaminants third.
Question 5: Which OSHA regulation requires employers to develop and implement a written Emergency Action Plan (EAP) when they have more than 10 employees?

- 90 dBA as an 8-hour TWA
- 95 dBA as an 8-hour TWA
Correct answer: 85 dBA as an 8-hour TWA
The action level of 85 dBA as an 8-hour time-weighted average triggers the requirement for a hearing conservation program, including audiometric testing.
