1. What is the primary purpose of a respiratory protection program
in a mining environment?
A. To reduce noise exposure
B. To protect workers from inhaling hazardous airborne contaminants
C. To improve equipment performance
D. To increase ventilation airflow
Rationale: A respiratory protection program is designed to protect
miners from airborne hazards such as dust, fumes, mists, vapors,
gases, and oxygen-deficient atmospheres. Respirators are used when
engineering or administrative controls cannot adequately reduce
exposure.
2. Which federal agency establishes health and safety standards for
U.S. mining operations?
,A. OSHA
B. MSHA
C. EPA
D. NIOSH
Rationale: The Mine Safety and Health Administration (MSHA)
enforces safety and health regulations for the mining industry under
the Federal Mine Safety and Health Act.
3. Before requiring a worker to wear a respirator, what must be
completed first?
A. Equipment maintenance
B. Medical evaluation
C. Annual safety meeting
D. Fire extinguisher inspection
Rationale: Workers must receive a medical evaluation to determine
whether they are physically capable of safely wearing a respirator
before fit testing and use.
4. Which organization certifies most respirators used in U.S.
workplaces?
A. ANSI
,B. NIOSH
C. MSHA
D. EPA
Rationale: NIOSH certifies respirators to ensure they meet required
performance standards for respiratory protection.
5. Which airborne hazard is commonly associated with mining
operations?
A. Sunlight
B. Respirable crystalline silica dust
C. Rainwater
D. Static electricity
Rationale: Respirable crystalline silica is produced during drilling,
blasting, crushing, and other mining activities. Long-term exposure
can lead to serious lung diseases.
6. Which respirator filters at least 95% of airborne particles but is not
resistant to oil?
A. P100
B. N95
, C. R95
D. HEPA cartridge
Rationale: N95 respirators filter at least 95% of non-oil-based airborne
particles and are widely used when appropriate for particulate
hazards.
7. What should a miner do before each use of a respirator?
A. Wash the filters
B. Replace all straps
C. Inspect the respirator for damage and defects
D. Paint the facepiece
Rationale: A pre-use inspection ensures that straps, valves, seals,
cartridges, and facepieces are in proper condition and capable of
providing protection.
8. A fit test is performed to verify:
A. Respirator color
B. Proper seal between the respirator and the wearer's face
C. Battery life
D. Filter expiration date
