Correct answer: Recommending a specific, reputable elevator contractor to a building owner to correct a violation found during an inspection.
Recommending a specific contractor to perform corrective work creates a conflict of interest, or the appearance of one. It implies a business relationship or favoritism that compromises the inspector's impartiality. The inspector's role is to identify non-compliance with the code, not to direct business to a particular company.
Question 27: Before beginning a detailed inspection of the driving machine and controller, what is the first critical safety procedure a QEI must perform after ensuring no passengers are in the car?
- Post warning signs on all landing entrances.
- Check the oil level in the gearbox or hydraulic reservoir.
- Manually test the brake to ensure it is holding the car.
- Perform a Lockout/Tagout (LOTO) on the main line disconnect. (Correct answer)
Correct answer: Perform a Lockout/Tagout (LOTO) on the main line disconnect.
The first and most critical step before working on or near elevator machinery is to de-energize the equipment by performing a proper Lockout/Tagout (LOTO) procedure on the main line disconnect switch. This prevents the accidental startup of the equipment, which could cause severe injury or death.
Question 28: A QEI is performing an inspection in a building where Firefighters' Emergency Operation is provided. What is the minimum pumping capacity required for the sump pump in the elevator pit?

ASME A17.1, Rule 2.2.2.5, specifies that for elevators with Firefighters' Emergency Operation, a drain or sump pump must be provided with the capacity to remove a minimum of 3,000 gallons per hour per elevator.
Question 29: What is the immediate and primary electrical function that occurs when any contact in the elevator's main safety circuit string (e.g., a hoistway door interlock, governor contact, or stop switch) is opened?
- The car lighting circuit is switched to battery backup.
- The in-car emergency alarm is automatically activated.
- The car leveling system is initiated to move the car to the nearest floor.
- Power is removed from the drive motor and the brake coil, causing the brake to set. (Correct answer)
Correct answer: Power is removed from the drive motor and the brake coil, causing the brake to set.
The safety circuit is a series circuit of contacts that, when intact, allows power to be supplied to the motor and brake. If any contact in this series is opened, it immediately breaks the circuit that energizes the drive motor and the brake coil. This de-energizes the brake, causing it to set by spring force, and removes power from the motor, bringing the elevator to a stop.
Question 30: During a Category 3 periodic test on a direct-acting hydraulic elevator, a pressure test is performed on the cylinder. What is the primary hazard this test is designed to detect?

Question 38: What is 'door dwell time' in the context of elevator door operation?
- The time the door remains fully open at a landing before the closing sequence begins (Correct answer)
- The maximum time allowed for nudging before the elevator initiates an automatic shutdown
- The time required for the door to complete its full opening stroke
- The delay between door closure completion and car departure from the floor
Correct answer: The time the door remains fully open at a landing before the closing sequence begins
Door dwell time is the period the elevator door remains fully open at a landing to allow passengers sufficient time to board or exit before the automatic closing sequence begins.
Question 39: A QEI arrives on-site to perform a witness test and discovers that the building's fire alarm system is offline for maintenance, which will prevent the proper testing of Firefighters' Emergency Operation. What is the appropriate action for the inspector to take?
- Perform all other parts of the inspection and note in the report that Phase I and Phase II could not be tested.
- Use a jumper wire to simulate the fire alarm input at the controller to complete the test.
- Postpone the inspection and inform the building representative that all required systems must be operational for the test to be conducted. (Correct answer)
- Proceed with the test, assuming the fire alarm system is functional and would have operated correctly.
Correct answer: Postpone the inspection and inform the building representative that all required systems must be operational for the test to be conducted.
An inspector's primary duty is to verify that all safety systems function as required by code. Witnessing a test requires observing the system's actual performance. If a critical related system, like the fire alarm, is not functional, the test cannot be properly and safely completed. The correct procedure is to postpone the inspection until all systems are available for a valid test.

- Attempt to move the car with each landing door in a partially open position (Correct answer)
- Measure the electrical resistance across each interlock contact pair
Correct answer: Attempt to move the car with each landing door in a partially open position
The inspector attempts to operate the car with each landing door partially open in turn to verify that the interlock circuit prevents car travel unless all hoistway doors are fully closed and locked.
Question 108: A QEI inspects a traction elevator machine room where sprinklers are installed. The inspector notes that the means to disconnect the main line power to the elevator (shunt trip) is activated by a smoke detector located at the top of the hoistway. Why is this a code violation?
- The disconnect should only be activated by the building's main fire alarm panel.
- Smoke detectors are not permitted to activate the shunt trip device. (Correct answer)
- The smoke detector must be located in the machine room, not the hoistway.
- The disconnect must be activated by a manual switch in the fire command center.
Correct answer: Smoke detectors are not permitted to activate the shunt trip device.
ASME A17.1, Rule 2.8.3.3.2, and NFPA 72 require that the activation of the shunt trip device be initiated by a heat detector, not a smoke detector. This is to ensure power is cut immediately *before* the application of water from the sprinkler, which is predicted by high heat. A smoke detector could shut down the elevator prematurely, potentially trapping passengers before a fire has grown to the point of sprinkler activation.
Question 109: 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?
- A broken rope safety
- An overspeed governor
- 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 110: What is the maximum gap permitted between the elevator car sill and the hoistway landing sill per ASME A17.1 for accessibility and safety?
- 1 inch
- 3/4 inch (Correct answer)
- 1/4 inch
- 1/2 inch
Correct answer: 3/4 inch
ASME A17.1 allows a maximum sill gap of 3/4 inch (19 mm) between the car sill and the landing sill to prevent cane tips, crutch tips, or small wheels from catching.
Question 111: What is the purpose of a 'rope gripper' device in a traction elevator system?
- To increase traction by pressing ropes into sheave grooves
- To prevent rope sway during high-speed travel
- To arrest the car by gripping the hoist ropes in the event of a rope slack or overspeed condition (Correct answer)
- To guide ropes through the machine room
Correct answer: To arrest the car by gripping the hoist ropes in the event of a rope slack or overspeed condition
A rope gripper is a safety device that clamps the hoist ropes to stop the car if rope slack or an overspeed condition is detected.
Question 112: What role does ASME A17.1 play in QEI standards?
- Developing elevator maintenance schedules
- Establishing uniform safety requirements for elevators (Correct answer)
- Defining elevator interior design specifications
- Regulating elevator operator training
Correct answer: Establishing uniform safety requirements for elevators
ASME A17.1 establishes uniform safety requirements for elevators, which are integral to QEI standards.
Question 113: Which of the following is generally prohibited from being installed inside an elevator hoistway, unless it is for the exclusive use of the elevator?
- Junction boxes for elevator signaling devices
- Traveling cables for car controls
- Steam pipes for building heat (Correct answer)
- Guarded light fixtures for illumination
Correct answer: Steam pipes for building heat
ASME A17.1 generally prohibits pipes, ducts, and wiring that are not used directly in connection with the elevator from being installed in the hoistway. Steam pipes present a particular danger due to the risk of discharge and heat affecting elevator operation and safety.
Question 114: A QEI is scheduled to perform an acceptance inspection on a new elevator installed by a company owned by the inspector's close family member. According to the QEI Code of Ethics, what is the most appropriate action for the inspector to take?
- Proceed with the inspection but disclose the relationship on the final report.
- Decline the inspection assignment and inform the scheduling party of the conflict of interest. (Correct answer)
- Ask a colleague to review the report before submission to ensure impartiality.
- Complete the inspection as scheduled, as professional training ensures objectivity.
Correct answer: Decline the inspection assignment and inform the scheduling party of the conflict of interest.
QEI standards and general professional ethics require inspectors to avoid conflicts of interest, or even the appearance of a conflict. Inspecting the work of a close family member's company creates an appearance of a conflict, which could compromise the perceived integrity of the inspection. The proper course of action is to decline the assignment to maintain professional impartiality.
Question 115: Which component of the car assembly is primarily responsible for engaging the governor rope to initiate a safety stop in an overspeed condition?
- The car frame (sling).
- The car door operator.
- The roller guides.
- The safety mechanism (safeties). (Correct answer)
Correct answer: The safety mechanism (safeties).
The safety mechanism, often referred to as the car safeties, is the component that is mechanically linked to the speed governor. When the governor detects an overspeed condition, it trips, causing the governor rope to activate the safety mechanism, which then clamps onto the guide rails to stop the car.
Question 116: What is the maximum travel distance permitted for a LULA elevator under ASME A17.1?
- 50 feet (Correct answer)
- 18 feet
- 25 feet
- 100 feet
Correct answer: 50 feet
ASME A17.1 limits LULA elevator travel to a maximum of 25 feet, making them suitable only for low-rise applications.
Question 117: What is the purpose of the secondary sheave (deflector sheave) in a traction elevator roping system?
- To tension the governor rope
- To absorb vibration from the drive motor
- To redirect the ropes to achieve the correct geometry between the car and counterweight (Correct answer)
- To provide additional traction
Correct answer: To redirect the ropes to achieve the correct geometry between the car and counterweight
A deflector sheave changes the direction of the ropes so that the car and counterweight travel paths align properly within the hoistway.
Question 118: According to the National Electrical Code (NEC) Article 620, when an elevator's disconnecting means is designated as supplying an emergency system load, what additional protection is required at that disconnecting means?
- A ground-fault circuit-interrupter (GFCI).
- An arc-fault circuit-interrupter (AFCI).
- A surge protective device (SPD). (Correct answer)
- A phase-reversal monitoring relay.
Correct answer: A surge protective device (SPD).
NEC Article 620.51(E) explicitly states that where any of the disconnecting means for an elevator has been designated as supplying an emergency system load, surge protection shall be provided. This protects the critical elevator controls from voltage transients.
Question 119: What is the key distinction between a car door contact and a hoistway door interlock?
- A car door contact only detects door position electrically; a hoistway door interlock both physically locks the door and contains an electrical contact (Correct answer)
- Both perform identical safety functions but are mounted on different doors
- A car door contact prevents car movement; a hoistway door interlock controls door speed
- A car door contact is mechanical; a hoistway door interlock is electrical
Correct answer: A car door contact only detects door position electrically; a hoistway door interlock both physically locks the door and contains an electrical contact
A car door contact is an electrical switch that detects car door position only, while a hoistway door interlock both mechanically locks the landing door and includes an electrical contact that must close before the car can move.
Question 120: Which condition would require a QEI inspector to flag the drive machine for corrective action?
- Normal motor current draw at full speed
- Normal operating temperature at rated load
- Slight vibration during acceleration within spec
- Excessive gear backlash in a geared machine beyond manufacturer tolerances (Correct answer)
Correct answer: Excessive gear backlash in a geared machine beyond manufacturer tolerances
Excessive gear backlash beyond manufacturer tolerances indicates gear wear that can cause rough operation, noise, and eventual failure requiring corrective action.
Question 121: When more than one elevator's driving machine is supplied by a single feeder circuit, what is the primary requirement for the overcurrent protective devices in each elevator's disconnecting means, according to NEC 620.62?
- They must all be located within a single, shared enclosure.
- They must be selectively coordinated with the supply-side overcurrent device. (Correct answer)
- They must all be of the same amperage rating.
- They must be non-fusible disconnects.
Correct answer: They must be selectively coordinated with the supply-side overcurrent device.
NEC 620.62 requires selective coordination when multiple elevators are on a single feeder. This ensures that a fault condition in one elevator will only trip the protective device for that specific elevator, rather than tripping the main feeder breaker and shutting down all elevators on that circuit.
Question 122: What is the maximum rated capacity for a LULA elevator under ASME A17.1?
- 2,100 lbs
- 1,400 lbs (Correct answer)
- 750 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 123: Which of the following must be provided on a separate, dedicated branch circuit within an elevator machine room, according to the National Electrical Code (NEC)?
- The machine room lighting and receptacle outlets. (Correct answer)
- The driving machine motor and the controller.
- The fire alarm initiating device and the emergency communication system.
- The car lighting and the machine room ventilation fan.
Correct answer: The machine room lighting and receptacle outlets.
NEC Article 620.23(C) requires that the machine room lighting and receptacle(s) be supplied by a separate, dedicated branch circuit. This ensures that power for illumination and tools is available even if the main power to the elevator driving machine is shut off for maintenance or due to a fault.
Question 124: An inspector notes that the main power disconnect for a traction elevator is located in an electrical closet adjacent to the machine room. The disconnect is not visible from the location of the elevator controller. According to NEC 620.51, why is this a violation?
- The disconnect must be located within sight of the motor controller. (Correct answer)
- The disconnect is not rated for the motor horsepower.
- The disconnect cannot be in a room with other electrical panels.
- The disconnect must be located inside the machine room, within 24 inches of the door.
Correct answer: The disconnect must be located within sight of the motor controller.
NEC 620.51(C) requires the disconnecting means to be located within sight of the motor controller. This is a critical safety requirement to ensure that a technician working on the controller can visually confirm that the power source has been de-energized.
Question 125: What does a 'traction loss' condition occur when in a traction elevator?
- The governor rope breaks
- The friction between the hoist ropes and drive sheave is insufficient to move the car (Correct answer)
- The motor loses electrical power
- The brake fails to release
Correct answer: The friction between the hoist ropes and drive sheave is insufficient to move the car
Traction loss occurs when the friction force between the hoist ropes and sheave grooves cannot overcome the load difference, causing the ropes to slip.
Question 126: A QEI is performing a periodic inspection and finds that the flexible hydraulic hose connecting the power unit to the cylinder line has minor bulging near a fitting, but no visible leaks. What is the appropriate action?
- Require immediate replacement of the flexible hose assembly. (Correct answer)
- Recommend wrapping the bulging section with high-pressure tape.
- Note it in the report for monitoring during the next inspection.
- Tighten the fitting to see if the bulge reduces in size.
Correct answer: Require immediate replacement of the flexible hose assembly.
According to ASME A17.1 inspection procedures (referenced in A17.2), any signs of damage or weakness, including bulging or distortion, in a flexible hydraulic hose assembly require it to be replaced. Bulging indicates a failure of the hose's internal reinforcement, and it cannot be safely left in service.
Question 127: During a periodic inspection of a traction elevator, the QEI needs to verify the functionality of the governor. As part of the procedure, the inspector must confirm the presence and condition of the governor rope. According to ASME A17.1, which of the following is a critical requirement for the governor rope?
- It must be replaced every five years regardless of condition.
- It must be of the size, material, and construction specified by the governor manufacturer. (Correct answer)
- It must be the same size and material as the hoist ropes.
- It must be lubricated with the same lubricant used for the guide rails.
Correct answer: It must be of the size, material, and construction specified by the governor manufacturer.
ASME A17.1 Requirement 8.6.3.4.1 specifies that the governor rope must be of the same size, material, and construction as what the governor manufacturer originally specified. Using a different type of rope could affect the tripping characteristics of the governor, compromising its function as a critical safety device.
Question 128: An inspector is examining the traveling cables for a new elevator installation. According to the National Electrical Code (NEC) Article 620, which of the following is a primary requirement for these cables?
- They must be enclosed in a rigid metal conduit for their entire length.
- They must be listed as elevator cable and possess flame-retardant characteristics. (Correct answer)
- They must contain a minimum of 25% spare conductors for future use.
- They must be supported by their steel core when the hang length exceeds 200 ft.
Correct answer: They must be listed as elevator cable and possess flame-retardant characteristics.
NEC 620.41 requires traveling cables to be listed for the purpose, which means they are tested for the unique flexing demands of elevator use and must be flame-retardant. While steel core support is required for long hang lengths (typically over 200 ft), the fundamental requirement for all traveling cables is being properly listed and flame-retardant. They are inherently flexible and not run in rigid conduit.
Question 129: A QEI is on top of an elevator car and measures the horizontal distance from the edge of the car top to the hoistway enclosure as 400 mm (approx. 16 in.). According to ASME A17.1 requirements for fall protection, what must be provided on this side of the car top?
- A single handrail positioned at 900 mm (35 in.) above the floor.
- A standard railing including a top rail, midrail, and toeboard. (Correct answer)
- A permanent yellow warning line painted 150 mm (6 in.) from the edge.
- A full-height solid guard extending 2100 mm (83 in.) from the floor.
Correct answer: A standard railing including a top rail, midrail, and toeboard.
ASME A17.1, Rule 2.14.1.7, mandates that where the free horizontal distance between the edge of the car top and the hoistway enclosure exceeds 300 mm (12 in.), a standard railing must be provided. This railing must consist of a top rail at a height of 1067 mm (42 in.), a midrail, and a toeboard to prevent falls.
Question 130: Upon completing a periodic inspection, a QEI identifies several code deficiencies. According to standard procedure, the inspector's report should be submitted to the client and/or the Authority Having Jurisdiction (AHJ):
- Within 24 hours, regardless of the severity of the findings.
- After confirming that all violations have been corrected by the maintenance provider.
- Promptly, in accordance with the AHJ's requirements or the contractual agreement. (Correct answer)
- Only after the inspection fees have been paid in full by the building owner.
Correct answer: Promptly, in accordance with the AHJ's requirements or the contractual agreement.
Professional practice and many jurisdictional rules require that inspection reports be filed promptly so that the responsible parties (building owner, AHJ) are made aware of any deficiencies in a timely manner. Specific timelines can vary, but delaying a report until repairs are made or payment is received is improper, as it withholds critical safety information. The report documents the condition of the equipment *at the time of inspection*.
Question 131: Which of the following is a recognized method for initiating Phase I Firefighters' Emergency Operation, causing the elevator to return to a designated recall level?
- Exceeding the rated load capacity of the elevator car.
- Activating a smoke detector in an elevator lobby or machine room. (Correct answer)
- Pressing and holding both the 'DOOR OPEN' and 'DOOR CLOSE' buttons simultaneously.
- A power failure followed by a switch to backup generator power.
Correct answer: Activating a smoke detector in an elevator lobby or machine room.
ASME A17.1 specifies that Phase I Firefighters' Emergency Operation can be initiated in two ways: manually with a key switch in the lobby, or automatically by the activation of specific fire alarm initiating devices, such as smoke detectors located in elevator lobbies, the machine room, or the hoistway.
Question 132: Why are QEI standards important in the elevator industry?
- To reduce elevator maintenance costs
- To promote elevator marketing campaigns
- To enhance elevator aesthetics
- To improve elevator safety and reliability (Correct answer)
Correct answer: To improve elevator safety and reliability
QEI standards are crucial for improving elevator safety and ensuring reliable operation, ultimately enhancing public safety and building compliance.
Question 133: A building owner informs a QEI that they wish to use the elevator machine room for general storage of building maintenance supplies to save space. Which of the following best explains why this is prohibited under standard safety codes?
- Stored materials can obstruct access to disconnecting means and control panels. (Correct answer)
- Only elevator-related parts and tools are permitted to be stored in the machine room.
- The room's ventilation system is not designed for storing chemical products.
- It violates the fire rating of the machine room enclosure.
Correct answer: Stored materials can obstruct access to disconnecting means and control panels.
ASME A17.1 and NEC Article 620 prohibit using machine rooms for storage of materials not related to the elevator equipment because such items can create fire hazards, obstruct clear working space around critical equipment, and block access to the main line disconnects needed for emergency and maintenance procedures.
Question 134: During a Category 5 safety test on a traction elevator, the governor overspeed switch must be tested. According to ASME A17.1, what is the primary function of this switch when it operates?
- To mechanically apply the car safeties directly to the guide rails.
- To remove power from the driving-machine motor and brake. (Correct answer)
- To send a signal to the fire alarm control panel.
- To initiate a controlled shutdown of the building's main power.
Correct answer: To remove power from the driving-machine motor and brake.
The governor overspeed switch is an electrical switch that operates before the governor mechanically trips the safeties. Its function is to remove power from the elevator's driving-machine motor and brake as a first means of stopping an overspeeding car.
Question 135: Device not provided if rise is 6.1 m or less, conforms to specific regulations when required
- Factor of Safety for Beams
- Top-of-car operating device (Correct answer)
- Remote interaction operation
- Hoistway Door Locking Devices
Correct answer: Top-of-car operating device
This refers to a control panel or device that allows authorized personnel to operate the elevator from the top of the elevator car. It's typically used during maintenance and servicing.
Question 136: What is the primary purpose of a hoistway door interlock?
- To prevent the hoistway door from being opened unless the car is within the unlocking zone (Correct answer)
- To connect the car door to the hoistway door mechanically
- To provide emergency lighting at each landing
- To control door closing speed
Correct answer: To prevent the hoistway door from being opened unless the car is within the unlocking zone
The hoistway door interlock prevents the landing door from being opened when the elevator car is not within the unlocking zone, protecting passengers from falling into the hoistway.
Question 137: While inspecting the installation of traveling cables in a new traction elevator, a QEI observes that the cables hang freely from the car to the hoistway junction box with no intermediate support. Why is this a potential violation?
- Traveling cables are only permitted on hydraulic elevators.
- The cables must be lubricated annually, and this installation prevents access.
- The cables are required to be encased in a rigid conduit.
- The installation lacks a means to prevent strain on the terminations and control twisting. (Correct answer)
Correct answer: The installation lacks a means to prevent strain on the terminations and control twisting.
Both NEC Article 620 and ASME A17.1 require that traveling cables be suspended and supported to prevent placing mechanical strain on the electrical terminations and to prevent damage from twisting or rubbing. This is typically accomplished with a suspension device or hanger.
Question 138: Which component on the car door physically engages with the landing door mechanism when the car arrives at a floor?
- Car door vane or clutch pick (Correct answer)
- Car gate electrical contact switch
- Door operator controller board
- Car door safety edge
Correct answer: Car door vane or clutch pick
The car door vane (or clutch pick) projects outward from the car door and engages with a roller on the landing door interlock assembly when the car arrives at a floor, transferring motion from the car operator to the hoistway door.
Question 139: During a routine inspection of a hydraulic elevator, the QEI notices that the in-ground cylinder is not equipped with any form of corrosion protection. The elevator was installed in an area with a high water table. Which of the following is the MOST significant risk associated with this finding?
- Contamination of the hydraulic fluid with water.
- Catastrophic failure of the cylinder due to electrolysis and corrosion. (Correct answer)
- Increased energy consumption due to friction.
- A gradual decrease in the elevator's rated speed.
Correct answer: Catastrophic failure of the cylinder due to electrolysis and corrosion.
Unprotected in-ground hydraulic cylinders are susceptible to corrosion and electrolysis, which can degrade the integrity of the steel. This can lead to an abrupt and catastrophic failure, causing the elevator to fall uncontrollably. This poses a significant safety hazard, far outweighing other potential issues.
