Question 1Elevating Devices

Under Ontario's elevating device legislation, which document authorizes a licensed contractor to perform work on elevating devices within a specific geographic area?

  1. A contractor licence issued by the Technical Standards and Safety Authority Correct answer.
  2. An operating permit posted in the elevator machine room
  3. A certificate of inspection issued after each periodic inspection
  4. A mechanic's certificate of qualification

Explanation

The contractor licence is the authorization granted to a business entity to perform elevating device work in a defined territory. Certificates of inspection and operating permits relate to individual devices, while a mechanic's certificate qualifies an individual worker rather than the company.

Question 2Elevating Devices

A passenger elevator is being placed into service for the first time. Which step must occur before the device may carry passengers?

  1. Submission of a maintenance log covering the prior twelve months
  2. A signed lease agreement between the owner and the building tenants
  3. A documented acceptance inspection confirming compliance with the applicable code Correct answer.
  4. A courtesy notification to the local fire department

Explanation

New elevating devices require an acceptance inspection to verify that installation conforms to the adopted code before being placed in operation. Maintenance logs and tenant agreements are unrelated to the safety acceptance process.

Question 3Elevating Devices

Which component is designed to stop an elevator car if it travels beyond the normal terminal landings?

  1. The door zone restrictor
  2. The compensation sheave
  3. The final limit switch Correct answer.
  4. The governor tension sheave

Explanation

The final limit switch is a protective device that opens the control circuit when the car passes its normal stopping range at a terminal. It acts as a backup to the normal terminal stopping means.

Question 4Elevating Devices

On a hydraulic elevator, which device prevents the car from descending at excessive speed if the down valve fails?

  1. The rupture valve or pipe rupture valve Correct answer.
  2. The car door interlock
  3. The governor tension switch
  4. The counterweight guide shoe

Explanation

A rupture valve is installed in the hydraulic line to stop the flow of fluid if the line breaks or flow exceeds a set rate, preventing uncontrolled descent. Door interlocks, guide shoes, and governor tension switches serve unrelated functions.

Question 5Elevating Devices

An escalator step is found to be loose or misaligned during a routine maintenance visit. Which action is required before the escalator is returned to passenger service?

  1. The escalator may operate at reduced speed until the next scheduled visit
  2. The escalator must be taken out of service and the condition corrected Correct answer.
  3. The step may be used if a warning sign is placed at the top landing
  4. The escalator may remain in service if an attendant is stationed nearby

Explanation

A loose or misaligned step is a hazard that could cause a passenger to trip or become entrapped, so the unit must be removed from service and repaired. Signs, reduced speed, or attendants do not eliminate the mechanical hazard.

Question 6Elevating Devices

Which of the following best describes the role of the Technical Standards and Safety Authority in Ontario's elevating device regime?

  1. It sets the purchase price of new elevating devices
  2. It manufactures and sells elevator control components
  3. It negotiates collective agreements for elevator mechanics
  4. It administers and enforces the safety legislation and regulations for elevating devices Correct answer.

Explanation

The TSSA is a delegated administrative authority that administers and enforces the Technical Standards and Safety Act and its regulations, including those governing elevating devices. It does not manufacture equipment, bargain labour contracts, or set prices.

Question 7Elevating Devices

What is the primary purpose of the car safety device (safety gear) on a traction elevator?

  1. To absorb vibration from the guide rails during normal running
  2. To level the car precisely at each landing
  3. To grip the guide rails and stop the car if it overspeeds in the down direction Correct answer.
  4. To hold the car doors closed during travel

Explanation

The safety gear is tripped by the overspeed governor and clamps the guide rails to arrest the car. It is a protective device that operates only in an emergency, not during normal operation.

Question 8Elevating Devices

A licensed elevating device mechanic is required to perform work on a device. Which credential must the individual hold?

  1. A certificate of qualification as an elevating device mechanic Correct answer.
  2. A certificate of inspection
  3. A contractor licence
  4. An operating permit

Explanation

Individual tradespeople must hold a certificate of qualification to perform elevating device work. The contractor licence belongs to the business, while permits and inspection certificates relate to the device itself.

Question 9Elevating Devices

During a scheduled maintenance visit, a mechanic observes that the elevator's door reopening device fails to function. What is the appropriate response under the safety legislation?

  1. Post a notice asking passengers to stand clear of the doors
  2. Take the device out of service until the door reopening device is repaired Correct answer.
  3. Record the defect and continue operating until the next monthly visit
  4. Reduce the door closing speed and continue operating

Explanation

A non-functioning door reopening device creates an entrapment hazard, and the device must be removed from service until it is repaired. Recording the defect without correction or relying on notices does not satisfy the duty to ensure safety.

Question 10Elevating Devices

A mechanic is testing the governor on a traction elevator. The governor is designed to trip the safety gear at a specified overspeed. Which condition must be verified during the test?

  1. That the governor trips at the speed specified for the rated speed of the installation Correct answer.
  2. That the governor trips only after the car reaches the pit buffers
  3. That the governor trips at the same speed as the car's contract speed
  4. That the governor trips whenever the car is empty

Explanation

The governor must be set to trip at the overspeed value specified for the installation's rated speed, as defined by the applicable code. Trip speed is a function of rated speed, not contract speed, buffer contact, or load.

Question 11Elevating Devices

A building owner wants to modernize an elevator's controller and door operator. Which statement best reflects the regulatory requirement for this work?

  1. The work may proceed because modernization is not considered an alteration
  2. The work may proceed if the contractor notifies the building tenants
  3. The alteration must be performed under permit and inspected for compliance with the code Correct answer.
  4. The work may proceed without a permit because the device already has an operating permit

Explanation

Alterations to elevating devices require a permit and inspection to confirm the modified equipment complies with the applicable code. An existing operating permit or tenant notification does not substitute for the permit and inspection process.

Question 12Elevating Devices

On a traction elevator, what is the function of the counterweight?

  1. To hold the car at a landing when the doors are open
  2. To balance the weight of the car and a portion of its rated load, reducing motor effort Correct answer.
  3. To tension the governor rope during normal operation
  4. To provide emergency braking during an overspeed condition

Explanation

The counterweight offsets the car weight plus a portion of the rated load so the machine only has to overcome the imbalance. It reduces the traction and power required during normal operation.

Question 13Elevating Devices

An escalator's comb plate is found to be damaged with broken teeth. What is the appropriate action?

  1. Place a caution cone near the comb plate and continue operation
  2. Remove the escalator from service until the comb plate is replaced Correct answer.
  3. Operate the escalator only in the down direction until repaired
  4. Operate the escalator only during peak hours

Explanation

A damaged comb plate can catch footwear or clothing and cause serious injury at the comb line, so the unit must be removed from service and repaired. Directional restrictions or cones do not eliminate the hazard.

Question 14Elevating Devices

Which document typically accompanies an elevating device and records the results of required periodic inspections and any orders issued?

  1. The equipment manufacturer's warranty
  2. The inspection certificate and associated field records maintained for the device Correct answer.
  3. The contractor's business licence certificate
  4. The mechanic's wallet certificate of qualification

Explanation

Inspection certificates and field records document the device's inspection history and any orders issued by the regulator. Contractor licences, mechanic certificates, and warranties do not record device inspection results.

Question 15Elevating Devices

During a periodic inspection, an inspector finds that the elevator's alarm bell does not sound from inside the car. What is the most likely consequence under the regulatory framework?

  1. An extension granted automatically until the next annual inspection
  2. A requirement to post a sign instructing passengers to use a phone
  3. An order requiring correction, with the device potentially removed from service until repaired Correct answer.
  4. A verbal warning with no follow-up because the bell is a non-mandatory feature

Explanation

Two-way communication or alarm provisions are required safety features for passenger elevators, and a failure is subject to an order and possible removal from service. The deficiency cannot be deferred automatically or resolved by signage.

Question 16Elevating Devices

A mechanic is performing maintenance on a hydraulic elevator and notices hydraulic fluid leaking from a fitting on the cylinder. Which action is most appropriate?

  1. Wipe the fitting and schedule the repair for the next quarterly visit
  2. Take the device out of service and repair the leak before returning it to operation Correct answer.
  3. Reduce the car's travel to the lower floors and continue operating
  4. Add fluid to the reservoir to compensate for the leak and continue operating

Explanation

A hydraulic leak at the cylinder or fittings can lead to loss of pressure and uncontrolled descent, so the unit must be removed from service until repaired. Topping up fluid or deferring repair does not address the underlying hazard.

Question 17Elevating Devices

Which of the following is a key responsibility of the owner of an elevating device under Ontario's safety legislation?

  1. Ensuring the device is maintained in a safe condition and inspections are current Correct answer.
  2. Setting the code requirements for new installations
  3. Performing the annual inspection personally
  4. Issuing certificates of qualification to mechanics

Explanation

Owners are responsible for keeping elevating devices in a safe operating condition and ensuring required inspections and maintenance are up to date. Inspections are performed by authorized inspectors, and qualifications and codes are set by the regulator.

Question 18Elevating Devices

An elevator is equipped with a door interlock. Which statement best describes the interlock's function?

  1. It prevents the car from moving unless the hoistway door is closed and locked Correct answer.
  2. It signals the controller when the car reaches the leveling zone
  3. It reverses the door if a passenger is detected in the doorway
  4. It keeps the car door open at a landing for a set dwell time

Explanation

The door interlock is a safety device that ensures the car cannot move unless the hoistway door is closed and locked. Door reversal and dwell time are handled by the door operator and controller, while leveling is detected by zone sensors.

Question 19Elevating Devices

An inspector observes that a machine-room access door is not self-closing and self-locking. Why is this a concern under the code?

  1. The door is required to be fire-rated only for aesthetic reasons
  2. The door must remain open to provide ventilation to the controller
  3. The machine room contains moving machinery and electrical equipment that must be secured from unauthorized entry Correct answer.
  4. The door must be self-closing to reduce noise in the hoistway

Explanation

Machine rooms house moving machinery and energized electrical equipment, and the self-closing, self-locking requirement restricts access to authorized persons. The requirement is a safety measure rather than an aesthetic or acoustic one.

Question 20Elevating Devices

A mechanic is replacing a rope on a traction elevator. Which consideration is most important for ensuring continued safe operation?

  1. Using a rope of the correct specification and verifying termination and tension Correct answer.
  2. Increasing the rope diameter to provide extra strength
  3. Reusing the existing terminations regardless of condition
  4. Selecting the least expensive rope of similar diameter

Explanation

Replacement ropes must match the specified construction and be properly terminated and tensioned to ensure load sharing and safe operation. Substituting a different rope or reusing worn terminations can compromise safety.

Question 21Elevating Devices

Which of the following situations would most likely require the immediate removal of an elevating device from service?

  1. The landing call button illumination has failed
  2. A cosmetic panel on the car interior is scratched
  3. A safety device is found to be inoperative during maintenance Correct answer.
  4. The car operating panel has a worn label

Explanation

An inoperative safety device presents an immediate risk to passengers and requires the device to be removed from service until repaired. Cosmetic damage and minor illumination or labeling issues do not create the same level of hazard.

Question 22Elevating Devices

A hydraulic elevator is observed to level slowly and then sink slightly at a landing. Which component is the most likely cause of the sinking?

  1. A worn guide shoe on the car
  2. A loose governor rope
  3. A misadjusted door interlock
  4. A leaking down valve or check valve in the hydraulic power unit Correct answer.

Explanation

Sinking at a landing indicates fluid is escaping past the down valve or check valve, allowing the car to drift downward. Guide shoes, door interlocks, and governor ropes do not control hydraulic holding.

Question 23Elevating Devices

An escalator is equipped with a broken step chain monitoring device. During inspection, the device is found to be bypassed. What is the significance of this finding?

  1. The bypass only affects passenger comfort and not safety
  2. The bypass is acceptable if the maintenance log documents it
  3. A required safety device has been defeated, creating a serious hazard that must be corrected before operation Correct answer.
  4. The bypass is acceptable if the escalator is lightly used

Explanation

Defeating a step chain monitoring device removes protection against chain failure, which can cause a serious accident. A bypassed safety device must be restored to service and the unit removed from operation until corrected.

Question 24Elevating Devices

A building has an elevator whose rated speed is being increased as part of a modernization. Which of the following must be reassessed because of the speed change?

  1. Only the landing call buttons
  2. Only the car interior finish
  3. Only the maintenance schedule frequency
  4. The governor trip speed and the adequacy of the safety gear and buffers Correct answer.

Explanation

Increasing rated speed affects the overspeed protection and energy absorption of the system, so the governor trip setting, safety gear, and buffers must be evaluated for the new speed. Cosmetic and scheduling items do not address the safety consequences.

Question 25Elevating Devices

During a safety gear test on a traction elevator, the car fails to stop within the required distance. Which of the following is the most appropriate engineering conclusion?

  1. The safety gear or governor may be out of adjustment or the guide rails may be inadequately lubricated or worn, and the device must remain out of service pending correction Correct answer.
  2. The result can be ignored if the car is lightly loaded
  3. The test distance is advisory and the car may return to service
  4. The result is acceptable if the machine brake also engages

Explanation

Failure to stop within the required distance indicates a possible deficiency in the safety gear, governor, or guide rail condition. The device must remain out of service until the cause is found and corrected and the test is successfully repeated.

Question 26Elevating Devices

Under Ontario's elevating device regulations, which body is responsible for issuing licences to elevator mechanics and contractors?

  1. The local municipal building department
  2. The Electrical Safety Authority
  3. The Technical Standards and Safety Authority Correct answer.
  4. The Ontario Ministry of Labour

Explanation

The Technical Standards and Safety Authority administers the elevating devices program, including licensing of mechanics and contractors, under the Technical Standards and Safety Act. Municipalities and other bodies do not issue these elevating device licences.

Question 27Elevating Devices

Which document must be kept in the machine room of an elevating device and made available to an inspector on request?

  1. The original architectural drawings
  2. The contractor's insurance certificate
  3. The building's fire safety plan
  4. The maintenance control program and log records Correct answer.

Explanation

Ontario requires a maintenance control program with records kept on site so inspectors can verify that required maintenance and tests have been performed. Fire plans, drawings, and insurance documents belong elsewhere and do not substitute for the maintenance record.

Question 28Elevating Devices

What is the primary function of the overspeed governor on a traction elevator?

  1. To detect excessive car speed and mechanically trigger the safety gear Correct answer.
  2. To keep the car level at each landing
  3. To regulate the motor's electrical current during acceleration
  4. To limit the load carried inside the car

Explanation

The governor continuously monitors car speed and, when a preset overspeed is reached, grips its rope to activate the safety gear that stops the car. It does not control motor current, levelling, or load.

Question 29Elevating Devices

On a hydraulic elevator, what is the purpose of the rupture valve (pipe rupture valve) installed in the cylinder supply line?

  1. To maintain constant oil temperature in the reservoir
  2. To smooth the ride during acceleration
  3. To stop the car from descending rapidly if the supply line breaks Correct answer.
  4. To prevent the pump from running dry

Explanation

A rupture valve senses abnormally high downward flow caused by a broken line and closes to arrest the car. It is a safety device against uncontrolled descent, not a temperature, ride-quality, or pump-protection control.

Question 30Elevating Devices

Which device is intended to prevent an escalator from starting or continuing to run if a passenger is caught at the comb plate?

  1. The handrail speed monitor
  2. The comb plate safety switch Correct answer.
  3. The skirt panel heater
  4. The step demarcation light

Explanation

The comb plate safety switch detects displacement of the comb plate and stops the escalator to protect a trapped passenger. Handrail monitors, demarcation lights, and skirt heaters serve different purposes.

Question 31Elevating Devices

What does the term 'rated load' mean for an elevator car?

  1. The average passenger load observed during a busy day
  2. The maximum load the car is designed to carry safely at its rated speed Correct answer.
  3. The weight of the car structure and sling alone
  4. The load at which the safety gear is tested

Explanation

Rated load is the design capacity the car may carry under normal operation at rated speed. It is a design limit, not the empty car weight, the test load for safety gear, or an observed average.

Question 32Elevating Devices

Which credential must a contractor hold to legally perform elevating device work in Ontario?

  1. A general contractor's building permit
  2. A municipal business licence only
  3. A professional engineer's seal
  4. A licence issued by the Technical Standards and Safety Authority Correct answer.

Explanation

Elevating device contractors must be licensed by the Technical Standards and Safety Authority to perform work on devices. Building permits, engineering seals, and municipal business licences do not authorize this work.

Question 33Elevating Devices

What is the purpose of the pit ladder and pit light in an elevator hoistway?

  1. To allow safe access and visibility for maintenance personnel working in the pit Correct answer.
  2. To illuminate the car interior during normal operation
  3. To support the counterweight guide rails
  4. To provide emergency egress for passengers trapped in the car

Explanation

The pit ladder and pit light exist so mechanics can enter and work in the pit safely with adequate illumination. They are not passenger egress routes, car lighting, or structural supports.

Question 34Elevating Devices

A mechanic must enter the hoistway from the car top to inspect the guide rails. Which practice best reflects safe procedure?

  1. Disable the door interlocks so the car can move with doors open
  2. Leave the car on normal operation and ride the top while the car moves
  3. Ask a passenger to hold the emergency stop button
  4. Place the car top inspection control in operation, verify stop switches, and use the car top operating station Correct answer.

Explanation

Working from the car top requires placing the inspection control in operation so the mechanic controls car movement at reduced speed, with stop switches verified. Normal operation, bypassed interlocks, or relying on a passenger are unsafe and non-compliant.

Question 35Elevating Devices

An inspector finds the machine-room access door lacks a self-closing and self-locking feature. What is the most appropriate response?

  1. Note it as a cosmetic issue with no action required
  2. Adjust the door to close slowly and leave the lock as is
  3. Remove the door to improve ventilation
  4. Record the deficiency and require correction before the device is returned to or continued in service Correct answer.

Explanation

Machine-room doors must be self-closing and self-locking to prevent unauthorized access to moving machinery. The deficiency must be recorded and corrected as a condition of continued service.

Question 36Elevating Devices

During a test, an elevator's door reopening device fails to reverse the door when an object is placed in its path. What is the correct interpretation?

  1. The reopening device only works when the car is moving
  2. A required safety function is impaired and the device must be taken out of service until repaired Correct answer.
  3. The test object was too small to be detected
  4. The device is optional and the car may continue in service

Explanation

The door reopening device protects passengers from being struck or trapped by closing doors; if it fails, a required safety function is lost and the unit should be removed from service until corrected. It is not optional, and detection does not depend on car motion.

Question 37Elevating Devices

A hydraulic elevator sinks slowly at a landing after levelling. Which component is the most likely cause?

  1. A leaking check valve or lowering valve in the power unit Correct answer.
  2. A misadjusted door operator
  3. A worn guide shoe
  4. A failed car light circuit

Explanation

Sinking after levelling indicates hydraulic fluid leaking past the check or lowering valve back to the reservoir. Guide shoes, door operators, and lighting do not cause the car to drift downward.

Question 38Elevating Devices

An escalator's step chain monitoring device has been bypassed. What is the appropriate action?

  1. Remove the escalator from service until the device is restored to operation Correct answer.
  2. Reduce the escalator speed to compensate
  3. Leave it bypassed if the escalator runs smoothly
  4. Add a warning sign and continue operation

Explanation

The step chain monitor detects chain stretch or breakage that could cause a dangerous pile-up; bypassing it removes a required safety function, so the unit must be taken out of service until restored. Smooth running or signage does not justify the bypass.

Question 39Elevating Devices

A building owner plans to increase an elevator's rated speed during modernization. What must happen before the device returns to service?

  1. The change must be reviewed and accepted as required, with tests confirming safe operation at the new speed Correct answer.
  2. The owner may proceed without notification if the work is done by a licensed mechanic
  3. The change is automatically approved once the controller is replaced
  4. Only the car interior needs updating

Explanation

Alterations affecting rated speed change the device's safety envelope and require review and acceptance, plus testing to confirm components such as the governor and safety gear perform correctly at the new speed. Licensed work alone does not remove the need for review and testing.

Question 40Elevating Devices

During a safety gear test, the car does not stop within the required distance. Which factor is the most likely cause?

  1. The counterweight is too heavy
  2. The car light is too dim
  3. The door operator is misaligned
  4. The governor tripping speed is set too high or the safety gear is poorly adjusted Correct answer.

Explanation

Stopping distance depends on the governor trip speed and safety gear adjustment; if either is out of specification the car will travel too far. Lighting, door alignment, and counterweight mass do not determine safety gear stopping distance in this way.

Question 41Elevating Devices

A mechanic is replacing suspension ropes on a traction elevator. Which consideration is most important for continued safe operation?

  1. Choosing ropes that are the least expensive available
  2. Using ropes of the correct specification and equal tension, with proper termination Correct answer.
  3. Installing ropes of a larger diameter for extra strength
  4. Reusing old rope clips where possible

Explanation

Replacement ropes must match the specified construction and be tensioned equally with correct terminations so load is shared and the drive performs as designed. Cost, reused clips, and arbitrary oversizing compromise safety and design compliance.

Question 42Elevating Devices

What is the function of the counterweight on a traction elevator?

  1. To provide emergency braking
  2. To keep the car doors closed
  3. To increase the car's rated load
  4. To balance most of the car weight and reduce motor effort Correct answer.

Explanation

The counterweight offsets most of the car and passenger weight so the machine only handles the imbalance, reducing required motor power and improving efficiency. It does not raise capacity, brake the car, or control doors.

Question 43Elevating Devices

An inspector observes that an elevator's alarm bell does not sound from inside the car. What is the appropriate action?

  1. Disable the bell to avoid nuisance noise
  2. Record the deficiency and require repair so occupants can summon help Correct answer.
  3. Reduce the car's rated load until repaired
  4. Ignore it because passengers carry cell phones

Explanation

The in-car alarm is a required means for trapped occupants to summon assistance; if it fails, the deficiency must be recorded and corrected. Cell phones are not a substitute, and disabling or derating does not address the hazard.

Question 44Elevating Devices

Which statement best describes the role of a door interlock on an elevator?

  1. It prevents car movement unless the door is closed and locked Correct answer.
  2. It reverses the door when an object is detected
  3. It holds the door open at a landing
  4. It slows the door as it approaches the closed position

Explanation

The interlock verifies that the car door and hoistway door are closed and locked before the car can move, preventing motion with an open door. Door slowing, reversing, and holding open are performed by other door system components.

Question 45Elevating Devices

A mechanic notices hydraulic fluid leaking from a fitting on the cylinder of a hydraulic elevator. What is the most appropriate immediate action?

  1. Wipe the fitting and continue operation
  2. Contain the leak, assess the hazard, and repair the fitting before returning the unit to service Correct answer.
  3. Reduce the car's speed and continue
  4. Add fluid to compensate for the loss

Explanation

A leaking cylinder fitting can lead to loss of hydraulic pressure and uncontrolled descent, so the leak must be contained, assessed, and repaired before service resumes. Wiping, topping up, or slowing the car does not correct the defect.

Question 46Elevating Devices

An escalator's comb plate is found with several broken teeth. What is the appropriate action?

  1. File the remaining teeth and continue operation
  2. Place a warning sign and continue operation
  3. Remove the escalator from service until the comb plate is replaced Correct answer.
  4. Increase the handrail speed to compensate

Explanation

Broken comb teeth create a serious entrapment hazard at the step/comb interface, so the unit must be taken out of service until the comb plate is replaced. Filing, signage, or speed changes do not remove the hazard.

Question 47Elevating Devices

A mechanic is testing the governor on a traction elevator and finds it trips at a speed well above the specified value. What is the most significant consequence?

  1. The counterweight will require rebalancing
  2. The car will level more accurately
  3. The safety gear may not engage in time to stop the car within the required distance Correct answer.
  4. The door operator will cycle faster

Explanation

If the governor trips late, the safety gear engages at a higher car speed, increasing stopping distance and the risk of injury or damage. Levelling, door cycling, and counterweight balance are unaffected by governor trip speed.

Question 48Elevating Devices

Which situation would most clearly warrant immediate removal of an elevating device from service?

  1. The safety gear or governor is found inoperative Correct answer.
  2. The landing sill has minor cosmetic wear
  3. The hall button requires a firmer press
  4. The car interior light flickers occasionally

Explanation

An inoperative safety gear or governor removes the primary protection against overspeed and uncontrolled descent, requiring immediate removal from service. Flickering lights, cosmetic sill wear, and stiff buttons are deficiencies that do not by themselves create the same immediate hazard.

Question 49Elevating Devices

A building owner asks whether a licensed mechanic can approve an alteration that changes the elevator's control system without any further review. Which statement is most accurate?

  1. Review is only required if the car speed changes
  2. The alteration must be reviewed and accepted as required, with records and tests documenting compliance Correct answer.
  3. A licensed mechanic's approval alone is sufficient
  4. No review is needed if the controller is a modern model

Explanation

Alterations to elevating devices require review and acceptance under the regulatory framework, supported by records and tests demonstrating compliance. A mechanic's licence authorizes work but does not replace the required review process, and modern equipment does not exempt a project.

Question 50Elevating Devices

An inspector finds that the machine-room access door is not self-closing and self-locking. What is the primary safety concern?

  1. The counterweight would become unbalanced
  2. The elevator would lose its levelling accuracy
  3. The machine room would become too warm
  4. Unauthorized persons could reach moving machinery and exposed parts Correct answer.

Explanation

A door that does not self-close and self-lock allows unauthorized access to moving machinery and exposed parts, creating a serious injury risk. Temperature, levelling, and counterweight balance are not the governing concerns.
