,Rationale: Class C extinguishers contain non-conductive agents for energized
electrical equipment.

OSHA?
A. 85 dBA with no action
B. 90 dBA with engineering controls required above that
C. 95 dBA no limit
D. 80 dBA
Rationale: OSHA PEL = 90 dBA over 8 hours; at 85 dBA, a hearing conservation
program is needed.
4. A confined space with hazardous atmosphere, engulfment risk, and internal
configuration requires:
A. Continuous forced air ventilation only
B. A permit-required confined space entry plan
C. Buddy system without written permit
D. Only gas monitoring
Rationale: Permit-required confined space (permit space) requires written
program, attendant, and rescue.
5. Which of the following is a correct hierarchy of fall protection?
A. Safety nets > guardrails > PPE
B. Guardrails > safety nets > personal fall arrest systems
C. Personal arrest > warning lines > guardrails
D. Warning lines > guardrails > nets
Rationale: OSHA hierarchy: eliminate hazard (guardrails) before passive (nets)
before active (PFAS).
6. Lockout/Tagout (LOTO) does NOT apply to which situation?
A. Servicing a conveyor belt with a motor disconnect
B. Cleaning a jammed paper shredder where guards are removed

C. Section 8 – Exposure controls
D. Section 11 – Toxicology
Rationale: Section 4 specifically outlines initial care for exposure.
9. A worker is using a ladder to reach a 20-foot high roof. The ladder base should
be set back from the wall approximately:
A. 2 feet
B. 5 feet (using 4:1 rule)
C. 10 feet
D. 15 feet
Rationale: 4:1 ratio means for every 4 ft height, 1 ft out; 20 ft height → 5 ft base
distance.
10. What color is typically used for “warning” of physical hazards (e.g., struck-by,
caught-in)?
A. Red
B. Green
C. Blue
D. Yellow
Rationale: Yellow indicates caution, physical hazards (OSHA 1910.144).
Domain 2: Hand Tools & Power Tools (Questions 11–20)
11. A hammer with a convex striking face is best used for:
A. Wood chisels
