C. 29 CFR 1926.500
D. 29 CFR 1910.1200
CORRECT ANSWER: B. 29 CFR 1910.303
RATIONALE: OSHA standard 1910.303 outlines the general requirements for electrical wiring and
equipment safety in the workplace.
Question 3: What is the minimum safe distance to maintain from overhead power lines when working
with ladders?
A. 5 feet
B. 10 feet
C. 15 feet
D. 20 feet
CORRECT ANSWER: B. 10 feet
RATIONALE: OSHA requires a minimum clearance of 10 feet from overhead power lines to prevent
electrical arc flashes or contact.
Question 4: Which class of fire extinguisher is appropriate for electrical fires?
,A. Class A
B. Class B
C. Class C
D. Class K
CORRECT ANSWER: C. Class C
RATIONALE: Class C extinguishers are designed for energized electrical equipment fires, using non-
conductive agents.
Question 5: What personal protective equipment (PPE) is essential when working on live electrical
circuits above 50 volts?
A. Cotton gloves
B. Insulated rubber gloves
C. Leather work gloves
D. No gloves are required
CORRECT ANSWER: B. Insulated rubber gloves
RATIONALE: Insulated rubber gloves provide the necessary dielectric protection against electric shock
when working on energized circuits.
Question 6: What does the acronym PPE stand for?
A. Personal Protection Equipment
B. Professional Protective Gear
C. Personal Protective Equipment
D. Primary Power Equipment
CORRECT ANSWER: C. Personal Protective Equipment
RATIONALE: PPE stands for Personal Protective Equipment, which includes items like helmets, gloves,
and eye protection.
Question 7: When lifting heavy objects, what is the correct body mechanic to prevent injury?
A. Bend at the waist
B. Twist while lifting
C. Lift with the legs
D. Hold the object away from the body
CORRECT ANSWER: C. Lift with the legs
RATIONALE: Lifting with the legs keeps the spine aligned and reduces strain on the lower back muscles.
Question 8: What is the maximum allowable height for a step ladder used in elevator shafts?
A. 10 feet
B. 12 feet
,C. 20 feet
D. Ladders are not allowed in shafts
CORRECT ANSWER: C. 20 feet
RATIONALE: Standard step ladders generally max out at 20 feet for safety stability, though specific job
site rules may vary.
Question 9: Which color typically indicates a danger or stop signal in safety signage?
A. Green
B. Yellow
C. Red
D. Blue
CORRECT ANSWER: C. Red
RATIONALE: Red is universally used in safety signage to indicate danger, stop, or fire protection
equipment.
Question 10: What is the primary hazard associated with working in an elevator hoistway?
A. Noise exposure
B. Fall from height
C. Chemical exposure
D. Radiation
CORRECT ANSWER: B. Fall from height
RATIONALE: The open nature of hoistways presents a significant risk of falling, requiring guardrails and
harnesses.
Question 11: Before entering an elevator pit, what must be verified first?
A. The lighting is working
B. The main line disconnect is locked out
C. The car is at the top floor
D. The phone is working
CORRECT ANSWER: B. The main line disconnect is locked out
RATIONALE: Ensuring the power is locked out prevents unexpected movement of the elevator car
while workers are in the pit.
Question 12: What is the purpose of a ground fault circuit interrupter (GFCI)?
A. To increase voltage
B. To protect against electrical shock
C. To reduce energy consumption
D. To stabilize frequency
CORRECT ANSWER: B. To protect against electrical shock
, RATIONALE: A GFCI detects imbalance in current flow and shuts off power to prevent shock hazards.
Question 13: Which tool is used to measure electrical resistance?
A. Voltmeter
B. Ammeter
C. Ohmmeter
D. Tachometer
CORRECT ANSWER: C. Ohmmeter
RATIONALE: An ohmmeter is specifically designed to measure resistance in ohms within a circuit.
Question 14: What is the safe voltage limit for hand-held lighting in confined spaces?
A. 120 volts
B. 240 volts
C. 12 volts
D. 480 volts
CORRECT ANSWER: C. 12 volts
RATIONALE: Low voltage (12V) lighting reduces the risk of severe electric shock in confined or wet
spaces.
Question 15: When should safety glasses be worn on the job site?
A. Only when grinding
B. Only when drilling
C. At all times in work zones
D. Only when instructed by a supervisor
CORRECT ANSWER: C. At all times in work zones
RATIONALE: Eye hazards can occur unexpectedly; constant wear ensures protection from flying debris.
Question 16: What is the function of a circuit breaker?
A. To store electrical energy
B. To protect circuits from overcurrent
C. To convert AC to DC
D. To measure voltage
CORRECT ANSWER: B. To protect circuits from overcurrent
RATIONALE: Circuit breakers automatically interrupt flow when current exceeds safe levels to prevent
fire or damage.
Question 17: Which type of helmet protects against electrical shock?
A. Class G
B. Class E
