Question 1Elevating Devices Code and Regulation

Under the Ontario Elevating Devices Code, which document is the primary adoption of the ASME A17.1 safety code for elevators and escalators in the province?

  1. The Electrical Safety Authority's wiring regulation
  2. The TSSA Act's incorporation by reference of CSA B44 only
  3. Ontario Regulation 209/01 made under the Technical Standards and Safety Act, 2000 Correct answer.
  4. The Building Code Act, 1992 alone

Explanation

The Elevating Devices Code is Ontario Regulation 209/01, a regulation under the Technical Standards and Safety Act, 2000, which adopts ASME A17.1 (with Ontario amendments) as the governing safety code. The Building Code governs construction requirements but does not itself adopt the elevator safety code.

Question 2Elevating Devices Code and Regulation

Who is responsible for ensuring that an elevating device is maintained in compliance with the Elevating Devices Code between inspections?

  1. The building's insurer
  2. The local municipality
  3. The licensed elevating device mechanic personally
  4. The registered contractor responsible for maintenance Correct answer.

Explanation

The registered contractor that performs maintenance is accountable for keeping the device compliant with the Code, and mechanics act under that contractor's licence. The owner also has duties, but the maintenance contractor carries the direct compliance obligation for servicing.

Question 3Elevating Devices Code and Regulation

What is the standard periodic inspection interval for a typical passenger elevator under the Ontario Elevating Devices Code?

  1. Every thirty-six months
  2. Every twelve months Correct answer.
  3. Every twenty-four months
  4. Every six months

Explanation

Passenger elevators are generally subject to annual inspection under the Code's inspection schedule. More frequent inspection may apply to specific device types, but the baseline for passenger elevators is yearly.

Question 4Elevating Devices Code and Regulation

Which licence category authorizes a person to perform maintenance, repairs, and adjustments on elevating devices in Ontario?

  1. Millwright certificate of qualification
  2. Elevating device mechanic licence Correct answer.
  3. Industrial electrician licence
  4. Elevating device contractor registration only

Explanation

The elevating device mechanic licence is the credential that permits hands-on maintenance, repair, and adjustment work on elevating devices. Contractor registration authorizes a business to offer services but does not itself qualify an individual to perform the work.

Question 5Elevating Devices Code and Regulation

Before an elevating device is placed into service for the first time, what must the registered contractor obtain?

  1. A warranty from the manufacturer
  2. A passing inspection and acceptance from the regulator Correct answer.
  3. A building permit only
  4. An electrical certificate only

Explanation

New installations must pass an acceptance inspection by the regulator before being put into service. The device cannot lawfully carry passengers until that acceptance is granted.

Question 6Elevating Devices Code and Regulation

What is the purpose of the Ontario amendments appended to ASME A17.1 within the Elevating Devices Code?

  1. To replace the national code entirely with provincial rules
  2. To adapt the national code to Ontario-specific requirements and administrative provisions Correct answer.
  3. To transfer enforcement to municipalities
  4. To remove inspection obligations for older devices

Explanation

The Ontario amendments modify and supplement ASME A17.1 to reflect provincial requirements, administrative procedures, and local conditions. They operate alongside the base code rather than replacing it wholesale.

Question 7Elevating Devices Code and Regulation

An owner wants to change the rated load of an existing elevator. What does the Code require before the change takes effect?

  1. Written approval and an alteration inspection by the regulator Correct answer.
  2. Only a note in the maintenance log
  3. Nothing, provided the car weight is unchanged
  4. Only notification to the building insurer

Explanation

Changing rated load is an alteration, which requires regulatory approval and inspection before the device returns to service. Alterations affecting capacity, speed, or travel are controlled because they affect safety margins.

Question 8Elevating Devices Code and Regulation

Which body administers and enforces the Elevating Devices Code in Ontario?

  1. The Technical Standards and Safety Authority Correct answer.
  2. The Electrical Safety Authority
  3. The Ontario Building Officials Association
  4. The Ministry of Labour

Explanation

The Technical Standards and Safety Authority administers and enforces the Elevating Devices Code under delegation from the province. It issues licences, conducts inspections, and takes compliance action.

Question 9Elevating Devices Code and Regulation

A mechanic finds a safety circuit jumper left installed on a controller. Under the Code and good practice, what is the correct immediate action?

  1. Leave it until the next scheduled maintenance visit
  2. Record it in the log and continue normal operation
  3. Replace the jumper with a permanent wire
  4. Remove the jumper, restore the safety circuit, and report the finding Correct answer.

Explanation

Jumped safety circuits defeat protective devices and create an immediate hazard, so the jumper must be removed and the circuit restored before the device operates. The finding should be documented and reported because it indicates a serious compliance breach.

Question 10Elevating Devices Code and Regulation

During a periodic inspection, a mechanic observes that the machine room door does not self-close and latch. What is the appropriate response?

  1. Treat it as a deficiency requiring correction before sign-off Correct answer.
  2. Ignore it because machine room doors are not covered
  3. Note it as a minor observation for the next visit
  4. Adjust the door only if the owner requests it

Explanation

Machine room doors must be self-closing and self-locking to restrict unauthorized access to equipment. A door that fails this requirement is a deficiency that must be corrected and cannot be signed off as compliant.

Question 11Elevating Devices Code and Regulation

What does the term 'rated load' mean in the context of an elevating device?

  1. The combined weight of passengers and counterweight
  2. The weight of the empty car
  3. The maximum load the device is designed and approved to carry Correct answer.
  4. The load at which the device was last tested

Explanation

Rated load is the design capacity the device is approved to carry, and it governs testing, capacity placards, and alteration thresholds. It is not the empty car weight or a test-only figure.

Question 12Elevating Devices Code and Regulation

An escalator handrail speed is found to deviate significantly from the step speed during inspection. Why does the Code control this relationship?

  1. To prevent loss of balance and falls caused by mismatched handrail and step speeds Correct answer.
  2. To reduce energy consumption
  3. To limit motor wear
  4. To satisfy warranty terms

Explanation

Handrail speed must closely track step speed so passengers relying on the handrail are not destabilized. A significant mismatch creates a fall hazard and is a code deficiency.

Question 13Elevating Devices Code and Regulation

What is the required action when an elevating device is involved in a serious incident causing injury?

  1. Report the incident to the regulator and preserve relevant evidence Correct answer.
  2. Repair the device and resume service without reporting
  3. Wait for the next scheduled inspection to disclose it
  4. Report only if the owner files a claim

Explanation

Serious incidents must be reported promptly to the regulator, and the device and relevant records should be preserved for investigation. Repairing and resuming service without reporting can destroy evidence and violate reporting duties.

Question 14Elevating Devices Code and Regulation

Which of the following best describes a 'major alteration' under the Elevating Devices Code?

  1. Routine lubrication of guide rails
  2. Replacement of a controller that changes the device's operating characteristics Correct answer.
  3. Replacing a burnt-out car light
  4. Tightening a loose handrail bolt

Explanation

Major alterations change the device's operating characteristics, capacity, or safety systems and require approval and inspection. Routine servicing tasks such as lubrication or lamp replacement are maintenance, not alterations.

Question 15Elevating Devices Code and Regulation

A contractor is asked to service a device whose licence has been suspended. What is the correct course of action?

  1. Proceed with the work because the mechanic is licensed
  2. Decline the work until the licence is reinstated Correct answer.
  3. Perform the work and report it afterward
  4. Perform only emergency repairs without documentation

Explanation

Servicing a device whose licence is suspended would perpetuate unlawful operation, so the contractor must decline until reinstatement. A mechanic's personal licence does not cure the device's suspended status.

Question 16Elevating Devices Code and Regulation

What does the Code require regarding the posting of capacity and inspection information inside a passenger elevator car?

  1. Only the emergency phone number
  2. Only the manufacturer's nameplate
  3. The rated load and required inspection certificate information must be displayed Correct answer.
  4. Nothing is required inside the car

Explanation

The car must display the rated load and current inspection certificate information so passengers and inspectors can verify capacity and compliance status. These postings are mandatory, not optional.

Question 17Elevating Devices Code and Regulation

A mechanic must enter a pit to inspect the buffer. Which practice aligns with the Code's safety requirements?

  1. Rely on a coworker to hold the door open
  2. Enter with the car at the top landing and the disconnect left on
  3. Use the pit stop switch, verify the stop, and confirm the car cannot move Correct answer.
  4. Enter without notifying anyone to save time

Explanation

Pit access requires using the pit stop switch and confirming the car is secured against movement before entering. Leaving the disconnect on or relying on informal safeguards exposes the mechanic to crushing hazards.

Question 18Elevating Devices Code and Regulation

What is the role of the counterweight in a traction elevator, and why does the Code address its guarding?

  1. It balances the car load; guarding prevents contact with moving parts Correct answer.
  2. It powers the motor; guarding prevents theft
  3. It provides emergency braking; guarding prevents noise
  4. It holds the governor rope; guarding prevents rope wear

Explanation

The counterweight offsets car and passenger load so the machine handles only the imbalance. Because it moves in the hoistway, the Code requires guarding to prevent contact with moving parts, particularly in pits and at floor openings.

Question 19Elevating Devices Code and Regulation

An owner proposes to disable the door reopen device to speed up service. How should the mechanic respond under the Code?

  1. Disable it only during peak hours
  2. Disable it temporarily and document the change
  3. Refuse because disabling a required safety device is a code violation Correct answer.
  4. Comply because the owner directs the work

Explanation

The door reopen device is a required safety feature that prevents passengers from being struck or trapped by closing doors. Disabling it, even at the owner's request, is a code violation and must be refused.

Question 20Elevating Devices Code and Regulation

What is the significance of the 'Certificate of Inspection' issued after a device passes inspection?

  1. It confirms compliance at the time of inspection and authorizes continued operation Correct answer.
  2. It transfers ownership of the device
  3. It permanently exempts the device from further inspection
  4. It replaces the need for maintenance records

Explanation

The certificate confirms the device met code requirements at the time of inspection and permits continued operation until the next required inspection. It is not a permanent exemption and does not eliminate maintenance obligations.

Question 21Elevating Devices Code and Regulation

A hydraulic elevator is observed to level slowly and to sink noticeably when stopped at a landing. Which code concern is most directly implicated?

  1. Counterweight balance
  2. Hydraulic cylinder or valve leakage affecting safe stopping and leveling Correct answer.
  3. Governor calibration
  4. Handrail speed

Explanation

Sinking at a landing points to hydraulic system leakage, such as a failing valve or cylinder, which affects safe stopping and leveling. The Code requires the hydraulic system to hold the car at a landing without objectionable creep.

Question 22Elevating Devices Code and Regulation

Under the Code, what is the primary function of the governor and safety mechanism on a traction elevator?

  1. To level the car at each floor
  2. To open the doors automatically
  3. To reduce motor current draw
  4. To stop and hold the car if it overspeeds in the down direction Correct answer.

Explanation

The governor detects overspeed and triggers the safeties, which grip the guide rails to stop and hold the car. This protective system is independent of normal leveling and door functions.

Question 23Elevating Devices Code and Regulation

A building owner wants to install a new elevator in a building where the hoistway was constructed before the current code edition. How should the applicable code requirements be determined?

  1. Apply no code because the building predates it
  2. Apply only the code edition in force when the building was built
  3. Apply only the manufacturer's installation manual
  4. Apply the current code to the new installation, with allowance for existing conditions as the code provides Correct answer.

Explanation

New installations must meet the code edition in force at the time of installation, while provisions may address interfacing with existing building conditions. The original construction date does not exempt a new device from current requirements.

Question 24Elevating Devices Code and Regulation

A mechanic discovers that a previous contractor installed a non-code-compliant door operator. What is the mechanic's obligation?

  1. Report and correct the deficiency so the device complies Correct answer.
  2. Wait for the regulator to discover it
  3. Document it only if the owner complains
  4. Leave it because it is not the mechanic's installation

Explanation

Each licensee is responsible for the compliance of devices they service, regardless of who created the deficiency. The mechanic must report and correct non-compliant conditions rather than defer to the prior installer.

Question 25Elevating Devices Code and Regulation

Which situation most clearly requires an alteration permit and inspection rather than routine maintenance?

  1. Replacing a worn guide shoe insert with an identical part
  2. Adjusting a door closer spring tension
  3. Changing the elevator's travel to serve an additional floor Correct answer.
  4. Cleaning the pit sump

Explanation

Extending travel to serve an additional floor changes the device's fundamental design and is an alteration requiring approval and inspection. Like-for-like part replacement, minor adjustments, and cleaning are maintenance activities.

Question 26Elevating Devices Code and Regulation

Under Ontario's elevating devices regulation, which document must a licensed contractor obtain before beginning installation of a new passenger elevator?

  1. A permit issued by the regulator Correct answer.
  2. A building occupancy certificate
  3. A mechanical insulation clearance
  4. A fire alarm verification form

Explanation

The regulation requires that a permit be obtained from the regulator before installation, alteration, or major repair work begins on an elevating device. The permit ties the work to a specific device and triggers the required inspections. Other documents listed relate to building occupancy or unrelated trades and do not authorize elevating device work.

Question 27Elevating Devices Code and Regulation

A licensed elevating device mechanic's licence is issued under Ontario regulation primarily to confirm which of the following?

  1. That the individual owns the devices being serviced
  2. That the individual is an employee of a specific contractor
  3. That the individual has building owner authorization
  4. That the individual has met qualification and competency requirements to perform device work Correct answer.

Explanation

Mechanic licensing confirms that the individual has demonstrated the qualifications and competency required to perform elevating device work safely. The licence is personal and is not tied to a particular employer, building, or ownership interest. Supervision and contractor licensing are separate requirements.

Question 28Elevating Devices Code and Regulation

Which standard forms the primary technical code adopted for elevating devices in Ontario, subject to provincial amendments?

  1. NFPA 70
  2. ASME A17.1/CSA B44 Correct answer.
  3. CSA B149.1
  4. ASME B30.2

Explanation

Ontario adopts ASME A17.1/CSA B44, the Safety Code for Elevators and Escalators, as the technical basis for elevating device requirements, with provincial amendments layered on top. NFPA 70 is the electrical code, CSA B149.1 covers gas appliances, and ASME B30.2 addresses overhead cranes.

Question 29Elevating Devices Code and Regulation

During a routine maintenance visit, a mechanic notices the elevator's recall operation for firefighter service does not function. What is the appropriate response under the Code?

  1. Disable the fire alarm interface to prevent nuisance recalls
  2. Record the deficiency, take the device out of service or restrict use as required, and arrange correction Correct answer.
  3. Continue normal operation and note the issue for the next scheduled visit
  4. Leave the decision to building occupants

Explanation

Firefighter service is a life-safety function, and a non-functioning recall is a deficiency that must be documented and corrected promptly. Where the deficiency affects safe operation, the device must be taken out of service or restricted until repaired. Deferring correction or disabling interfaces is not permitted.

Question 30Elevating Devices Code and Regulation

A contractor's licence lapses while a maintenance contract is ongoing. What is the correct course of action for the mechanic employed there?

  1. Transfer the work to the building owner temporarily
  2. Perform only emergency repairs without a licence
  3. Continue working because the mechanic's own licence is still valid
  4. Stop performing licensed device work until the contractor's licence is reinstated Correct answer.

Explanation

Elevating device work must be performed under a valid contractor licence, so the mechanic cannot lawfully continue licensed work while the employer's licence is lapsed. The mechanic's personal licence does not substitute for the contractor licence. Work should resume only after reinstatement.

Question 31Elevating Devices Code and Regulation

A building owner asks whether a device must continue to comply with the code edition in force when it was installed. What is the most accurate statement?

  1. Code compliance is optional for devices older than twenty years
  2. Only newly installed devices are ever subject to inspection
  3. Once installed, a device is permanently exempt from all code requirements
  4. Existing devices must meet current requirements when alterations or major repairs are made, and ongoing maintenance obligations apply regardless Correct answer.

Explanation

Devices are generally permitted to remain in service under the code edition applicable at installation, but alterations, major repairs, and ongoing maintenance obligations are judged against current requirements. Periodic inspection continues throughout the device's service life. There is no blanket exemption based on installation date or age.

Question 32Elevating Devices Code and Regulation

What does the Code require regarding the guarding of exposed moving parts such as sheaves and belts in a machine room?

  1. Guarding is needed only during installation
  2. Guards must be provided to prevent contact with moving parts Correct answer.
  3. Guarding is optional if the room is locked
  4. Guarding is required only for escalators

Explanation

The Code requires guarding of exposed moving machinery parts to protect mechanics and others who may access the machine space. Locking the room does not eliminate the need for guarding because authorized personnel still work near the equipment. Guarding requirements apply to elevators as well as escalators.

Question 33Elevating Devices Code and Regulation

Which of the following best describes the purpose of the periodic inspection requirement for elevating devices in Ontario?

  1. To determine the building's insurance premium
  2. To set the device's resale value
  3. To replace the need for routine maintenance
  4. To verify continued compliance and safe operating condition at defined intervals Correct answer.

Explanation

Periodic inspections verify that the device continues to comply with code requirements and operates safely, at intervals defined by regulation. They supplement, but do not replace, the maintenance required of the licensed contractor. Inspection findings can lead to orders for correction.

Question 34Elevating Devices Code and Regulation

A mechanic is asked to alter the control system of a device in a way that changes its operating characteristics. What should the mechanic confirm first?

  1. That the alteration can be completed in one day
  2. That the owner has notified the insurer
  3. That the building has spare parts available
  4. That the alteration is within the scope of the contractor's licence and a permit has been obtained Correct answer.

Explanation

Alterations require a permit and must be performed by a licensed contractor within the scope of its licence. The mechanic should verify permitting and licensing before starting work. Parts availability, insurance notice, and scheduling do not authorize the alteration.

Question 35Elevating Devices Code and Regulation

What is the primary reason the Code requires a means to manually lower a hydraulic elevator car in an emergency?

  1. To test the hydraulic fluid level
  2. To reduce electricity consumption
  3. To align the car with the landing during normal service
  4. To allow controlled evacuation or rescue when power or the pump fails Correct answer.

Explanation

A manual lowering means allows the car to be brought to a landing for evacuation or rescue when the power supply or pumping system fails. It is a safety provision, not an energy-saving or routine levelling device. Fluid level checks are unrelated to this requirement.

Question 36Elevating Devices Code and Regulation

An escalator's combplate is found damaged with broken teeth. What action does the Code and safe practice require?

  1. Continue operating and note it at the next inspection
  2. Cover the damaged area with tape and continue
  3. Reduce passenger load and continue operating
  4. Remove the escalator from service until the combplate is repaired or replaced Correct answer.

Explanation

A damaged combplate presents an entrapment hazard at the step-comb intersection and requires the escalator to be taken out of service until repaired. Interim measures such as tape or load reduction do not address the hazard. The device should return to service only after proper correction.

Question 37Elevating Devices Code and Regulation

Which item is typically required to be displayed in the car or at the landing to inform passengers about the device's regulatory status?

  1. The current inspection certificate or tag showing the device is licensed to operate Correct answer.
  2. The manufacturer's warranty certificate
  3. The contractor's business licence number only
  4. The building's fire safety plan

Explanation

The Code requires evidence that the device is currently licensed or inspected to be posted so passengers and inspectors can see it. This is typically the inspection certificate or tag. Contractor business details, warranties, and fire plans do not serve this purpose.

Question 38Elevating Devices Code and Regulation

A mechanic finds that the pit ladder is missing several rungs. How should this be handled under the Code?

  1. Ask building staff to install a temporary wooden rung
  2. Treat it as a deficiency affecting safe pit access and arrange repair before relying on it Correct answer.
  3. Ignore it because ladders are not code items
  4. Use the ladder carefully while repairs are pending

Explanation

Pit ladders are required for safe access, and damaged rungs make access unsafe, so the deficiency must be corrected before the ladder is relied upon. Improvised repairs by non-qualified persons are not acceptable. Pit access safety is a code concern.

Question 39Elevating Devices Code and Regulation

Which situation would most likely require notification to the regulator as an incident rather than routine servicing?

  1. A routine oil change on the hydraulic power unit
  2. A planned cleaning of the pit floor
  3. A scheduled replacement of a burnt-out car light
  4. A car moved with the doors open and a passenger was injured Correct answer.

Explanation

An unintended car movement with doors open that causes injury is an incident requiring notification to the regulator. Routine maintenance tasks such as oil changes, lamp replacement, and pit cleaning are ordinary servicing. Incident reporting supports investigation and corrective action.

Question 40Elevating Devices Code and Regulation

Under the Code, which of the following is a required characteristic of the hoistway enclosure for a passenger elevator?

  1. It must be constructed entirely of glass
  2. It must be enclosed and resist fire as required to protect the hoistway Correct answer.
  3. It may be open to the building corridor
  4. It must be lined with combustible material

Explanation

The hoistway must be enclosed with construction that resists fire spread as required, protecting the shaft and limiting smoke movement. Glass and open hoistways are only permitted under specific conditions and are not general requirements. Combustible lining is not permitted where it would compromise fire resistance.

Question 41Elevating Devices Code and Regulation

What is the purpose of the Code requirement that a car be provided with an emergency communication means in buildings where the device serves the public?

  1. To allow the mechanic to order parts
  2. To permit remote starting of the elevator
  3. To record passenger complaints
  4. To allow trapped passengers to summon assistance Correct answer.

Explanation

Emergency communication allows passengers trapped in a stalled car to summon assistance promptly. It is a life-safety provision, not a maintenance or administrative tool. Remote starting and complaint recording are unrelated functions.

Question 42Elevating Devices Code and Regulation

A contractor proposes to use a non-code-compliant substitute part for a safety device because the correct part is back-ordered. How should the mechanic respond?

  1. Ask the building owner to approve the substitution
  2. Install the substitute temporarily without documentation
  3. Install the substitute and monitor it
  4. Refuse the substitution and keep the device out of service until a compliant part is available Correct answer.

Explanation

Safety devices must meet code requirements, and substituting a non-compliant part is not permitted even for convenience. The device should remain out of service until a compliant component is installed. Owner approval cannot override the code.

Question 43Elevating Devices Code and Regulation

Which of the following best describes the role of the regulator's inspector during a periodic inspection?

  1. To perform the contractor's routine maintenance
  2. To set the maintenance contract price
  3. To design device alterations
  4. To assess compliance with the code and issue orders or conditions where deficiencies are found Correct answer.

Explanation

The regulator's inspector assesses compliance and may issue orders or conditions when deficiencies are identified. The inspector does not perform the contractor's maintenance, set commercial prices, or design alterations. Those are responsibilities of the licensed contractor and owner.

Question 44Elevating Devices Code and Regulation

A device has been sealed out of service by the regulator. What does this mean for the owner?

  1. The owner may operate it if a mechanic is present
  2. The device must not be operated until the regulator authorizes return to service Correct answer.
  3. The owner may operate it on weekends only
  4. The owner may operate it at reduced speed

Explanation

A seal out of service means the device is prohibited from operation until the deficiency is corrected and the regulator authorizes return to service. Reduced speed, mechanic presence, or time restrictions do not lift the prohibition. Unauthorized operation can lead to enforcement action.

Question 45Elevating Devices Code and Regulation

What is the primary safety purpose of the Code requirement for car door interlocks on passenger elevators?

  1. To reduce door maintenance costs
  2. To allow the doors to remain open during travel
  3. To speed up passenger loading
  4. To prevent the car from moving unless the doors are closed and locked Correct answer.

Explanation

Door interlocks ensure the car cannot move unless the car doors are closed and locked, protecting passengers from falls into the hoistway. The requirement is a safety provision, not a means of speeding loading or reducing costs. Doors must not remain open during travel.

Question 46Elevating Devices Code and Regulation

A building owner wants to increase the travel of an existing elevator to serve a new floor. Which regulatory characterization applies?

  1. Routine maintenance needing no notification
  2. A cosmetic change outside the code's scope
  3. A repair exempt from code requirements
  4. An alteration requiring a permit and inspection Correct answer.

Explanation

Increasing travel to serve a new floor changes the device's design and operation, making it an alteration that requires a permit and inspection. It is not routine maintenance or a cosmetic change. The work must be performed by a licensed contractor and inspected before use.

Question 47Elevating Devices Code and Regulation

A mechanic observes that the governor rope is worn and frayed. What is the appropriate action under the Code?

  1. Shorten the rope to remove the frayed section
  2. Take the device out of service and replace the rope before returning it to service Correct answer.
  3. Reduce the car speed and continue operating
  4. Note the condition for the next annual inspection

Explanation

The governor rope is part of the safety system, and a worn or frayed rope may prevent the safety from setting, so the device must be taken out of service and the rope replaced. Speed reduction or shortening the rope does not restore reliable safety operation. Deferring correction leaves a serious hazard.

Question 48Elevating Devices Code and Regulation

Which of the following best explains why the Code requires buffers at the bottom of the hoistway?

  1. To align the car with the lowest landing
  2. To provide a resting place for the car between runs
  3. To reduce noise during normal operation
  4. To absorb kinetic energy and limit deceleration if the car or counterweight overtravels downward Correct answer.

Explanation

Buffers absorb kinetic energy and limit deceleration when the car or counterweight travels beyond the normal bottom landing. They are not a resting place or a normal levelling aid. Noise reduction and landing alignment are not their purpose.

Question 49Elevating Devices Code and Regulation

A mechanic is asked to work on a device while the building is occupied and the car is in service. Which approach best reflects the Code's safety requirements?

  1. Ask a passenger to hold the door open
  2. Rely on the car being parked at a landing
  3. Follow lockout and hoistway-access procedures to prevent unexpected movement before entering work areas Correct answer.
  4. Work quickly during low-traffic periods

Explanation

Work on or near an operating device requires lockout and proper hoistway-access procedures to prevent unexpected car movement. Relying on parking position, passengers, or low traffic does not provide reliable protection. These procedures are fundamental code safety requirements.

Question 50Elevating Devices Code and Regulation

Which of the following best describes the Code's treatment of escalator skirt panels and their relationship to the steps?

  1. Skirt panels may be removed to increase step width
  2. Skirt panels are decorative and not regulated
  3. Skirt panels must be positioned to limit gaps that could entrap footwear or clothing Correct answer.
  4. Skirt panels must be made of glass

Explanation

Skirt panels are required to be positioned so that gaps at the step edges are limited, reducing entrapment risk. They are functional safety components, not decorative items, and cannot be removed to widen the step. Glass is not a mandated material.
