RATIONALE & ELEVATOR/ESCALATOR TECHNICAL CERTIFICATION
PREPARATION MATERIAL
• How to use this material: Work through each question independently before
checking the correct answer and EXPERT RATIONALE — this active recall method
maximizes retention and simulates real exam pressure for best results.
• Document features: 200 verified questions with 5-option MCQs, bold highlighted
correct answers, detailed EXPERT RATIONALE, full exam topic coverage, and
vertical answer formatting for easy reading and self-testing.
Q1. What is the primary code governing the safety of escalators and moving
walks in the United States?
A. NFPA 70 – National Electrical Code
B. OSHA 29 CFR 1910
C. ANSI B11.19
D. ASME A17.1 / CSA B44 Safety Code for Elevators and Escalators
E. ISO 9001 Quality Management Standard
, Correct Answer: D. ASME A17.1 / CSA B44 Safety Code for Elevators and
Escalators
EXPERT RATIONALE: ASME A17.1 (adopted jointly with CSA B44 in Canada) is
the foundational safety code for escalators, elevators, and moving walks in the
United States. It specifies design, construction, installation, operation, inspection,
testing, maintenance, and repair requirements.
Q2. What is the maximum permissible angle of inclination for a standard
passenger escalator?
A. 20 degrees
B. 25 degrees
C. 30 degrees
D. 35 degrees
E. 45 degrees
Correct Answer: C. 30 degrees
EXPERT RATIONALE: ASME A17.1 specifies that escalators shall have an angle of
inclination not exceeding 30 degrees from the horizontal. Steeper angles increase
the risk of passenger falls and require different safety considerations.
Q3. Which component of an escalator is responsible for moving the steps in a
continuous loop?
A. The handrail drive
B. The truss
C. The step chain
D. The comb plate
E. The skirt panel
, Correct Answer: C. The step chain
EXPERT RATIONALE: The step chain is a continuous loop of linked chain that
attaches to each step and drives them in a circuit from the lower landing through
the incline and back. It is driven by the main drive sprocket connected to the motor.
Q4. What is the purpose of the comb plate on an escalator?
A. To guide the handrail along its track
B. To mesh with the step tread grooves at the landing to allow safe passenger
transition
C. To support the weight of the truss
D. To prevent steps from derailing on the incline
E. To distribute lubrication to the step chain
Correct Answer: B. To mesh with the step tread grooves at the landing to
allow safe passenger transition
EXPERT RATIONALE: The comb plate (or comb segment) has finger-like
projections that interlock with the grooves on the step treads at both the upper and
lower landings, creating a smooth transition surface for passengers to step on and
off safely, and preventing objects from getting caught between the step and the
landing plate.
Q5. Which safety device immediately stops an escalator when a step sinks
below the running surface?
A. Handrail speed sensor
B. Missing step device
C. Step level device (step sagging switch)
D. Overspeed governor
E. Phase failure relay
, Correct Answer: C. Step level device (step sagging switch)
EXPERT RATIONALE: The step level device (step sagging switch) is triggered
when a step sinks below the normal running plane, indicating a broken step axle or
chain link. It immediately halts the escalator to prevent a passenger from falling
into the gap.
Q6. The rated speed of a standard escalator shall not exceed:
A. 0.30 m/s
B. 0.45 m/s
C. 0.50 m/s
D. 0.65 m/s
E. 0.75 m/s
Correct Answer: C. 0.50 m/s
EXPERT RATIONALE: Per ASME A17.1, the rated speed of an escalator shall not
exceed 0.50 m/s (approximately 100 feet per minute). This speed limit is set to
ensure passenger safety and comfort during boarding, riding, and alighting.
Q7. What is the function of the broken step chain device on an escalator?
A. It lubricates the step chain automatically
B. It detects and stops the escalator when the step chain breaks or becomes
excessively elongated
C. It measures the speed of the handrail
D. It prevents reversal of the escalator direction
E. It monitors the motor temperature
Correct Answer: B. It detects and stops the escalator when the step chain
breaks or becomes excessively elongated
