1. What is the primary purpose of an elevator governor?
A. Increase car speed
B. Control door operation
C. Activate safety devices during overspeed
D. Balance counterweight
Rationale: The governor detects overspeed and triggers safety
mechanisms to stop the elevator.
Correct answer: C. Activate safety devices during overspeed
2. Which code primarily governs elevator installation safety
standards in the U.S.?
A. NEC
B. ASME A17.1
C. OSHA 1910

A. Control speed
B. Stop the car at terminal limits safely
C. Increase traction
D. Balance cables
Rationale: Buffers absorb energy if the car overshoots the
landing.
Correct answer: B. Stop the car at terminal limits safely
5. Which device prevents elevator doors from opening
between floors?
A. Door interlock
B. Governor
,C. Hoistway switch
