QEI Accessibility, LULA, and Special Installations 2 — Questions and Answers
Question 1: What is the maximum rated capacity for a LULA elevator under ASME A17.1?
- 750 lbs
- 1,400 lbs (Correct answer)
- 2,100 lbs
- 2,500 lbs
Correct answer: 1,400 lbs
ASME A17.1 limits LULA elevator rated load capacity to a maximum of 1,400 pounds.
Question 2: When inspecting a platform lift (vertical wheelchair lift) under ASME A18.1, what safety device must be present to prevent the platform from descending if a person or object is in the path below?
- An overspeed governor
- A broken rope safety
- A sensing device or guard under the platform (Correct answer)
- A pit buffer
Correct answer: A sensing device or guard under the platform
ASME A18.1 requires a sensing device or protective guard beneath the platform to detect obstructions and prevent the lift from crushing anyone below.
Question 3: Which standard governs the installation and inspection of vertical platform lifts and inclined platform lifts in the US?
- ASME A17.1
- ASME A17.3
- ASME A18.1 (Correct answer)
- ASME B20.1
Correct answer: ASME A18.1
ASME A18.1 (Safety Standard for Platform Lifts and Stairway Chairlifts) governs the design, installation, and inspection of vertical and inclined platform lifts.
Question 4: What door timing requirement does ADA set for elevator doors to remain open long enough for a person using a wheelchair to enter?
- Doors must remain open at least 2 seconds
- Doors must remain fully open for a minimum of 3 seconds (Correct answer)
- Doors must stay open until a button is pressed to close
- Doors must remain open for at least 10 seconds on every call
Correct answer: Doors must remain fully open for a minimum of 3 seconds
ADA Standards require elevator doors to remain fully open for a minimum of 3 seconds to allow adequate boarding time for wheelchair users and people with mobility impairments.
Question 5: What is the required mounting height range for elevator control buttons per ADA Standards for side-reach approach?
- 15 to 48 inches above the floor (Correct answer)
- 20 to 54 inches above the floor
- 24 to 60 inches above the floor
- 30 to 66 inches above the floor
Correct answer: 15 to 48 inches above the floor
ADA Standards require operable controls, including elevator buttons, to be mounted between 15 and 48 inches above the floor for side-reach accessibility.
Question 6: Under ASME A17.1, what is a key difference between a LULA elevator and a standard passenger elevator regarding the hoistway enclosure?
- LULA elevators do not require a fully enclosed hoistway
- LULA elevators require fire-rated hoistway enclosures with sprinklers
- LULA elevators may use a non-fire-rated enclosure if travel is 25 feet or less in certain conditions (Correct answer)
- LULA elevators must be installed in concrete shafts only
Correct answer: LULA elevators may use a non-fire-rated enclosure if travel is 25 feet or less in certain conditions
ASME A17.1 Section 5.3 allows LULA elevators under certain conditions to use non-fire-rated hoistway enclosures, unlike full passenger elevators which require fire-rated construction.
