1. What is the primary purpose of an escalator handrail?
A. Support passengers’ weight
B. Guide passengers safely
C. Improve escalator speed
D. Reduce noise
B. Guide passengers safely
Rationale: The handrail provides stability and helps passengers
maintain balance while using the escalator, reducing the risk of
falls.
2. Which component drives the escalator steps?
A. Handrail motor
B. Step chain
C. Gearbox
D. Comb plate
C. Gearbox
Rationale: The gearbox connects the motor to the step chain,
transferring power to move the escalator steps.
,3. What is the function of the comb plate?
A. Guides the handrail
B. Connects steps at the landing
C. Prevents objects from getting trapped
D. Lubricates the step chain
C. Prevents objects from getting trapped
Rationale: Comb plates are located at the top and bottom
landings to prevent shoes, clothing, or objects from getting
caught between the steps and the landing.
4. What is the correct frequency for performing a full safety
inspection on an escalator?
A. Daily
B. Weekly
C. Monthly
D. Annually
D. Annually
Rationale: A full, comprehensive safety inspection is typically
required annually, though daily and monthly checks are for
operational and minor safety issues.
5. Which type of lubrication is generally recommended for escalator
step chains?
A. Water-based oil
B. High-pressure grease
C. Light machine oil
D. Heavy motor oil
C. Light machine oil
Rationale: Light machine oil reduces friction on moving chains
without attracting excessive dust or debris.
,6. What should be the first step before performing maintenance on
an escalator?
A. Notify building management
B. Turn off power and lockout/tagout
C. Inspect handrails
D. Test step speed
B. Turn off power and lockout/tagout
Rationale: Lockout/tagout ensures the escalator cannot be
energized while maintenance is in progress, preventing
accidents.
7. What is the purpose of the step demarcation line?
A. Decorate the step
B. Indicate step position for safety
C. Reduce noise
D. Guide the handrail
B. Indicate step position for safety
Rationale: Step demarcation lines help passengers clearly see
the edge of each step to avoid tripping.
8. What is the typical cause of escalator handrail slippage?
A. Excessive lubrication
B. Misalignment of drive system
C. Dirty steps
D. Worn comb plates
B. Misalignment of drive system
Rationale: Handrail slippage usually occurs when the drive
motor, gears, or rollers are misaligned, preventing proper
movement.
9. How often should the step chain be inspected?
A. Daily
, B. Weekly
C. Monthly
D. Annually
B. Weekly
Rationale: Weekly inspections allow early detection of wear,
elongation, or damage to prevent chain failure.
10. Which safety device stops the escalator if a step becomes
jammed?
A. Handrail switch
B. Step chain switch
C. Skirt switch
D. Emergency stop button
B. Step chain switch
Rationale: Step chain switches detect abnormal resistance in the
step chain and shut down the escalator to prevent damage or
accidents.
11. What is the main function of the skirt panel?
A. Support the steps
B. Protect the gap between steps and side panels
C. Reduce escalator noise
D. Guide handrails
B. Protect the gap between steps and side panels
Rationale: Skirt panels prevent passengers’ footwear or clothing
from getting caught in the gap between the steps and side walls.
12. What is the standard speed for a commercial escalator?
A. 0.25 m/s
B. 0.5 m/s
C. 1.0 m/s
D. 1.5 m/s
