operation, inspection, testing, and maintenance of elevators in Georgia?
A. NFPA 70
B. ASME B18.2.1
C. ASME A17.1/CSA B44
D. OSHA 1910

escalators, ensuring safety and compliance.
4. How often must a state-licensed elevator inspector perform an
inspection of a passenger elevator?
A. Monthly
, B. Annually
C. Semi-annually
D. Every five years
Georgia requires regular inspections, typically semi-annual, to ensure
elevator safety.
5. The emergency stop switch in an elevator is designed to:
A. Resume normal operation
B. Immediately halt elevator movement
C. Reduce elevator speed gradually
D. Signal the fire department
The emergency stop allows passengers or maintenance personnel to stop
the elevator in a hazardous situation.
6. Which type of elevator uses a hydraulic piston to move the car?
A. Traction
B. Hydraulic
C. Machine-room-less
D. Rack and pinion
Hydraulic elevators operate via a piston that pushes the car upward,
commonly used in low- to mid-rise buildings.
7. Elevator pit depth is critical for:
A. Aesthetic design
B. Safety during car over-travel
C. Reducing cable wear
D. Increasing travel speed
Proper pit depth prevents the elevator car from striking the pit floor
during over-travel.
8. In a traction elevator, what is the purpose of the counterweight?
A. Reduce car speed
B. Balance the elevator car weight
C. Control door operation
, D. Provide emergency braking
The counterweight offsets the car and passenger load, reducing motor
energy requirements.
9. Which component opens and closes the elevator doors?
A. Governor
B. Traction sheave
C. Door operator
D. Car frame
The door operator mechanically moves the doors and ensures safe
operation.
10. A hoistway door interlock ensures that:
A. The car moves faster
B. The elevator cannot operate unless the door is closed
C. The motor stops during maintenance
D. The lighting system functions
Interlocks prevent elevator movement when doors are open, enhancing
passenger safety.
11. The rated load of an elevator is defined as:
A. Maximum weight the hoist cable can carry
B. Maximum weight the elevator is designed to safely carry
C. Minimum operating weight of the car
