, Question 1
Under ASME A18.1-2023, a platform lift is installed in a non-enclosed
hoistway. Which condition mandates a permanently installed enclosure?
A. The lift travels more than 60 in. (1524 mm) above the floor.
B. The lift is located in a building accessible to the public.
C. The lift is installed outdoors and exposed to weather.
D. The lift is used in a residential dwelling unit.
Correct Answer: A - The lift travels more than 60 in. (1524 mm)
above the floor.
RATIONALE
ASME A18.1-2023 requires an enclosure when the travel exceeds 60
in. above the floor or the lift is not within a shaftway. Options B, C,
and D do not independently trigger the enclosure requirement; the
critical factor is travel height and exposure to adjacent spaces.
Question 2
A stairway chairlift is being designed for a curved stairway with multiple
intermediate landings. Which requirement of ASME A18.1-2023 most directly
affects the minimum width of the chair and its clearance to the stairway walls?
A. The chair must accommodate a 95th percentile adult male.
B. The chair must not reduce the stairway width below 36 in. (914 mm) at
any point.
C. The chair must have a minimum seat width of 18 in. (457 mm).
D. The chair must allow a 5 in. (127 mm) clearance from the wall for the
armrest.
Correct Answer: B - The chair must not reduce the stairway
width below 36 in. (914 mm) at any point.

, RATIONALE
A18.1-2023 requires that the stairway chairlift not reduce the required
means of egress width; typically, this means maintaining at least 36 in.
clear. Seat width and clearances are specified but the governing
constraint for stairway installations is preservation of egress width.
Question 3
For a platform lift with a rated load of 750 lb, what is the minimum required
safety factor for the suspension ropes according to ASME A18.1-2023?
A. 5
B. 8
C. 10
D. 12
Correct Answer: D - 12
RATIONALE
ASME A18.1-2023 specifies a minimum safety factor of 12 for
suspension ropes on platform lifts. This is higher than for elevators
due to the increased risk associated with the open design and public
exposure of platform lifts.
Question 4
A platform lift is equipped with a slack rope safety device. Which of the
following best describes the required action when the device is actuated?
A. The lift shall stop immediately and require manual reset.
B. The lift shall stop and automatically return to the lowest landing.
C. The lift shall continue to operate at reduced speed.
D. The lift shall sound an alarm but continue to operate.
Correct Answer: A - The lift shall stop immediately and require
manual reset.
Page 3
, RATIONALE
A slack rope safety device must cause the lift to stop and require
manual resetting to ensure the condition is investigated. Automatic
return or continued operation is not permitted under A18.1-2023.
Question 5
In accordance with ASME A18.1-2023, what is the maximum allowable speed
for a stairway chairlift?
A. 30 ft/min (0.15 m/s)
B. 50 ft/min (0.25 m/s)
C. 75 ft/min (0.38 m/s)
D. 100 ft/min (0.51 m/s)
Correct Answer: B - 50 ft/min (0.25 m/s)
RATIONALE
A18.1-2023 limits stairway chairlift speed to 50 ft/min (0.25 m/s) to
ensure safe boarding and travel. Higher speeds are permitted for
platform lifts but not for chairlifts.
Question 6
A platform lift is installed in a hoistway with a pit. What is the minimum pit
depth required by ASME A18.1-2023 when the lift is provided with a hinged
platform?
A. 12 in. (305 mm)
B. 24 in. (610 mm)
C. 36 in. (914 mm)
D. 48 in. (1219 mm)
Correct Answer: B - 24 in. (610 mm)
