What this exam covers
5 real sample questions
Why does 1910.134(g)(1)(i)(A) prohibit facial hair that comes between the sealing surface of a tight-fitting facepiece and the face?
A. Because facial hair in the sealing area breaks the seal or interferes with valve function, allowing contaminated air to leak in
B. Because it is a grooming standard unrelated to respirator performance
C. Because facial hair damages the respirator material over time
D. Because it violates a general company dress code
Show answer and reasoning

Correct answer: A. Because facial hair in the sealing area breaks the seal or interferes with valve function, allowing contaminated air to leak in

  • B: This is a functional safety requirement, not a cosmetic grooming rule.
  • C: Facial hair does not physically damage the respirator material.
  • D: The prohibition is a safety-driven OSHA requirement, not a general dress code matter.
Source: 29 CFR 1910.134(g)(1)(i)(A)
Under 1910.134(a)(1), what is the primary objective when controlling occupational diseases caused by contaminated air?
A. To prevent atmospheric contamination, as far as feasible, through engineering controls such as enclosure, ventilation, or substitution of less toxic materials
B. To issue a respirator to every employee regardless of exposure
C. To rely on respirators as the first line of defense in every case
D. To rotate employees through the contaminated area to limit individual exposure time
Show answer and reasoning

Correct answer: A. To prevent atmospheric contamination, as far as feasible, through engineering controls such as enclosure, ventilation, or substitution of less toxic materials

  • B: A respirator is issued when necessary to protect health, not automatically to every employee.
  • C: This inverts the standard's hierarchy; engineering controls come first.
  • D: Rotation schedules are not the control method 1910.134(a)(1) describes.
Source: 29 CFR 1910.134(a)(1)
Who is responsible for establishing and maintaining the written respiratory protection program?
A. The employer
B. Each individual employee who wears a respirator
C. The respirator manufacturer
D. OSHA
Show answer and reasoning

Correct answer: A. The employer

  • B: Employees participate in the program but do not carry the establishment duty.
  • C: The manufacturer builds the equipment; it does not run the workplace program.
  • D: OSHA sets and enforces the requirement; it does not administer any one employer's program.
Source: 29 CFR 1910.134(a)(2)
When must the written respiratory protection program be updated?
A. As necessary to reflect changes in workplace conditions that affect respirator use
B. Only once, at the time it is first written
C. Every five years regardless of workplace changes
D. Only when OSHA conducts an inspection
Show answer and reasoning

Correct answer: A. As necessary to reflect changes in workplace conditions that affect respirator use

  • B: A program written once and never revisited would not track new hazards or new respirator types.
  • C: No fixed five-year cycle is set by the standard.
  • D: The update duty exists independent of whether or when OSHA inspects.
Source: 29 CFR 1910.134(c)(1)
What must a written respiratory protection program include regarding atmosphere-supplying respirators?
A. Procedures to ensure adequate air quality, quantity, and flow of breathing air
B. A list of every employee's home phone number
C. The purchase price of each unit
D. A guarantee that the respirator will never fail
Show answer and reasoning

Correct answer: A. Procedures to ensure adequate air quality, quantity, and flow of breathing air

  • B: Personal contact lists are not a program element.
  • C: Cost information is not a program requirement.
  • D: No equipment guarantee is required or realistic; the program instead requires maintenance and inspection procedures.
