1. What is the primary purpose of a respirator?
a) To increase oxygen intake
b) To filter out harmful airborne contaminants
c) To measure air pressure
d) To improve comfort while working
b) To filter out harmful airborne contaminants
Rationale: Respirators are designed to protect the user from inhaling
hazardous dusts, fumes, vapors, or gases.
2. Which MSHA standard requires miners to be trained in the use of
respiratory protection?
, a) 30 CFR Part 57.5001
b) 30 CFR Part 57.5060
c) 30 CFR Part 57.5061
d) 30 CFR Part 57.1500
c) 30 CFR Part 57.5061
Rationale: 30 CFR Part 57.5061 mandates training for miners on
respiratory protection and its proper use.
3. What is the first step before using a respirator?
a) Inspect the respirator for damage
b) Put it on immediately
c) Adjust the straps while wearing gloves
d) Test air pressure in the mine
a) Inspect the respirator for damage
Rationale: Inspecting the respirator ensures it is free of defects that
could compromise protection.
4. Which type of respirator is designed to protect against dust, mists, and
fumes?
a) Powered Air-Purifying Respirator (PAPR)
b) Air-supplied respirator
c) Particulate respirator
d) Self-contained breathing apparatus (SCBA)
c) Particulate respirator
, Rationale: Particulate respirators filter out solid and liquid airborne
particles but not gases or vapors.
5. What does the “fit test” ensure for a respirator?
a) That it filters particles effectively
b) That it is the correct size and forms a proper seal
c) That it increases oxygen levels
d) That it is comfortable for long shifts
b) That it is the correct size and forms a proper seal
Rationale: Fit testing ensures the respirator seals to the face,
preventing leakage of contaminants.
6. How often must a respirator fit test be performed?
a) Every month
b) Annually
c) Every 5 years
d) Only when damaged
b) Annually
Rationale: MSHA requires annual fit testing to ensure continued
effectiveness and proper seal.
7. Which respirator type is used when oxygen levels are below 19.5%?
a) Air-purifying respirator
b) Self-contained breathing apparatus (SCBA)
c) Half-mask respirator
d) Dust mask
, b) Self-contained breathing apparatus (SCBA)
Rationale: SCBAs provide independent air supply, essential in
oxygen-deficient environments.
8. Which condition would require the use of a respirator with a high-
efficiency particulate air (HEPA) filter?
a) Low oxygen levels
b) Airborne dust containing silica
c) Gaseous chlorine
d) Hot, humid conditions
b) Airborne dust containing silica
Rationale: HEPA filters capture very fine particles, such as silica dust,
which are hazardous when inhaled.
9. How should a respirator be cleaned?
a) By rinsing in tap water only
b) Using approved cleaning methods and disinfectants
c) By wiping with a dry cloth
d) By air-drying without cleaning
b) Using approved cleaning methods and disinfectants
Rationale: Proper cleaning prevents contamination and maintains
respirator effectiveness.
10. What should you do if a respirator is damaged or broken?
a) Continue using it
b) Repair it with tape
