SECTION 1: ELEVATOR SAFETY AND CODES Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A state inspector is reviewing the governor on a 12-year-old traction elevator rated at
500 FPM. The inspector notes that the governor tripping speed must meet ASME A17.1
requirements for minimum overspeed protection. At what percentage of rated car speed
must the car governor be set to trip at a minimum?
A. 115% of rated speed
B. 110% of rated speed
C. 125% of rated speed
D. 100% of rated speed
Correct Answer: A
Rationale: ASME A17.1 requires car governors to trip at not less than 115% of rated
speed to ensure the safety mechanism activates before dangerous overspeed
conditions occur. 110% is typically the setting for the electrical overspeed switch, not
,the mechanical governor trip point, and 125% is the load test requirement, not the
governor setting.
Question 2 of 50
A 28-year-old mechanic is performing routine maintenance in the pit of a 6-story
hydraulic elevator. Before descending into the pit, the mechanic must follow standard
safety protocols to ensure the elevator cannot be operated while they are below. What
are the two primary safety precautions required when first entering any elevator pit?
A. Engage the hoistway door interlock and turn on the car light
B. Open the pit stop switch and turn on the pit light
C. Remove the main disconnect fuse and tag the controller
D. Place warning cones at all landing entrances and call the office
Correct Answer: B
Rationale: The pit stop switch removes power from the control circuit to prevent
unexpected car movement, and the pit light provides necessary illumination for safe
working conditions below the lowest landing. The door interlock and car light do not
protect the mechanic from pit hazards, and removing fuses is not the standard pit entry
procedure.
Question 3 of 50
A building manager has scheduled the five-year safety test for a 20-year-old traction
elevator that serves a busy downtown office tower. The elevator has a rated capacity of
3,500 lbs and travels at 700 FPM. According to ASME A17.1 Category 5 testing
requirements, what must be verified during this full-load safety test?
A. Governor trip speed with no load in the car
B. Full load test at 125% rated capacity with safeties and buffers tested
C. Oil buffer pressure test at 150% system pressure
D. Door closing force measurement at each landing
, Correct Answer: B
Rationale: Category 5 testing for traction elevators requires a full-load test at 125% rated
capacity to verify that safeties, governors, buffers, and braking systems perform
correctly under maximum load conditions. No-load governor tests are performed during
annual Category 1 testing, and buffer pressure tests are specific to hydraulic systems.
Question 4 of 50
During a modernisation project at a hospital, the installation crew is completing the
hydraulic piping for a new 4-stop elevator. The project foreman reminds the team that
ASME code requires specific valve placement to protect against uncontrolled descent in
the event of a hydraulic line failure. What valve must be installed between the hydraulic
power unit and the jack?
A. Pressure relief valve at the tank return line
B. Check valve at the pump discharge
C. Flow control valve at the cylinder inlet
D. Manually operated shutoff valve between the machine and jack
Correct Answer: D
Rationale: ASME A17.1 requires a manually operated shutoff valve between the
hydraulic machine and the jack so that the system can be isolated for maintenance or in
an emergency. The pressure relief valve protects against overpressure but does not
isolate the jack, and a check valve alone does not provide the required manual isolation
capability.
Question 5 of 50
A construction crew is erecting scaffolding around the exterior of a 10-story building to
facilitate a hoistway extension. The safety coordinator sets up barricades at the base of
the scaffolding to prevent unauthorized access to the work zone. What is the minimum
required height for an OSHA-approved barricade?
