counterweight?
A. Electrical shock
B. Moving machinery
C. Noise exposure
D. Heat stress
CORRECT ANSWER: B. Moving machinery
Rationale: The counterweight moves in the opposite direction of the car and poses a crushing
or striking hazard to personnel in the pit.
Question 5: What must be done before entering a hoistway for maintenance?
A. Notify the building owner
B. Place the elevator on inspection operation
,C. Turn off the mainline disconnect
D. Lock out and tag out the power source
CORRECT ANSWER: D. Lock out and tag out the power source
Rationale: OSHA and ASME standards require lockout/tagout procedures to ensure energy
sources are isolated before entering hazardous zones.
Question 6: What is the minimum clearance required between the car roof and the hoistway
ceiling when the car is at the highest landing?
A. 12 inches
B. 18 inches
C. 24 inches
D. 36 inches
CORRECT ANSWER: B. 18 inches
Rationale: A minimum headroom clearance is required to ensure safety for workers on the car
top when the car is at the top landing.
Question 7: Which color is required for the car top stop switch?
A. Yellow
B. Green
C. Red
D. Blue
CORRECT ANSWER: C. Red
Rationale: Emergency stop switches must be red to indicate their function clearly and
distinguish them from other controls.
Question 8: What is the purpose of the governor rope tension sheave?
A. To lift the car
B. To maintain tension on the governor rope
C. To guide the car rails
D. To operate the door motor
CORRECT ANSWER: B. To maintain tension on the governor rope
Rationale: The tension sheave ensures the governor rope remains taut so the governor can
accurately detect overspeed conditions.
Question 9: How often must safety gear be tested on a traction elevator?
A. Every year
B. Every 3 years
C. Every 5 years
D. Every 10 years
CORRECT ANSWER: C. Every 5 years
Rationale: ASME A17.1 mandates a full safety gear test every 5 years to ensure proper
engagement and stopping capability.
Question 10: What is the minimum depth required for an elevator pit if the buffer stroke is 24
inches?
A. 24 inches
B. 30 inches
,C. 48 inches
D. 60 inches
CORRECT ANSWER: C. 48 inches
Rationale: The pit depth must accommodate the buffer stroke plus additional clearance for
safety and maintenance access.
Question 11: Which lock type is required for hoistway doors?
A. Magnetic lock
B. Mechanical lock with electrical contact
C. Friction lock
D. Hydraulic lock
CORRECT ANSWER: B. Mechanical lock with electrical contact
Rationale: Hoistway doors must have a mechanical lock to prevent opening from the landing
and an electrical contact to verify locking.
Question 12: What is the maximum allowable gap between the hoistway door and the
landing sill?
A. 1/2 inch
B. 3/4 inch
C. 1 inch
D. 1 1/4 inches
CORRECT ANSWER: A. 1/2 inch
Rationale: Limiting the gap prevents objects from falling into the hoistway and reduces the risk
of passenger injury.
Question 13: What must be provided in the machine room for ventilation?
A. Natural airflow only
B. Mechanical ventilation or air conditioning
C. Open windows only
D. No ventilation required
CORRECT ANSWER: B. Mechanical ventilation or air conditioning
Rationale: Machine rooms require adequate ventilation to prevent overheating of equipment
and ensure a safe working environment.
Question 14: What is the required illumination level in the machine room?
A. 5 foot-candles
B. 10 foot-candles
C. 20 foot-candles
D. 50 foot-candles
CORRECT ANSWER: B. 10 foot-candles
Rationale: ASME A17.1 specifies a minimum illumination level to ensure visibility for
maintenance and inspection tasks.
Question 15: Which fire extinguisher class is recommended for elevator electrical fires?
A. Class A
B. Class B
, C. Class C
D. Class D
CORRECT ANSWER: C. Class C
Rationale: Class C extinguishers are designed for energized electrical equipment, reducing the
risk of shock.
Question 16: What is the function of the door interlock?
A. To lock the car door
B. To prevent car movement if the door is open
C. To open the door automatically
D. To signal the dispatcher
CORRECT ANSWER: B. To prevent car movement if the door is open
Rationale: The interlock ensures the elevator cannot move unless all hoistway doors are closed
and locked.
Question 17: What is the minimum width of a pit ladder?
A. 12 inches
B. 16 inches
C. 20 inches
D. 24 inches
CORRECT ANSWER: B. 16 inches
Rationale: Pit ladders must be wide enough to provide safe access and egress for maintenance
personnel.
Question 18: Where must the mainline disconnect be located?
A. Inside the car
B. In the pit
C. In the machine room or control space
D. On the car top
CORRECT ANSWER: C. In the machine room or control space
Rationale: The disconnect must be accessible to authorized personnel in the machine room to
cut power to the drive machine.
Question 19: What is the purpose of the buffer in the pit?
A. To lift the car
B. To absorb energy if the car descends too low
C. To guide the counterweight
D. To store hydraulic fluid
CORRECT ANSWER: B. To absorb energy if the car descends too low
Rationale: Buffers protect the car and passengers by decelerating the car safely in the event of
an over-travel.
Question 20: Which PPE is mandatory when working on the car top?
A. Safety glasses only
B. Hard hat and safety shoes
