Question 1Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Under the Massachusetts elevator regulations, which activity requires a permit from the state elevator inspection authority before work begins?

  1. Cleaning the pit floor after a service call
  2. Replacing a burned-out hall call button lens
  3. Altering the controller of an existing elevator Correct answer.
  4. Changing a light bulb in the car ceiling

Explanation

Massachusetts requires a permit for construction, installation, alteration, and certain major repairs of elevators before work starts. Altering the controller changes the operating characteristics of the equipment, so it falls within permit scope. Routine maintenance items such as lamps, lenses, and housekeeping do not require permits.

Question 2Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new hydraulic elevator in a Massachusetts building. Which document must be submitted with the permit application to show the design complies with the adopted code?

  1. Construction drawings and specifications prepared for the installation Correct answer.
  2. A letter from the building owner accepting liability
  3. The manufacturer's warranty certificate
  4. The maintenance contract signed with the owner

Explanation

Permit applications for elevator installation must be accompanied by drawings and specifications demonstrating code compliance. Warranty certificates, owner liability letters, and maintenance contracts do not establish design compliance. The drawings are the technical basis the regulator reviews.

Question 3Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Who is permitted to perform the acceptance test on a newly installed elevator in Massachusetts?

  1. A licensed elevator mechanic or inspector authorized under the regulations Correct answer.
  2. The elevator manufacturer's sales representative
  3. Any building maintenance employee
  4. The general contractor's superintendent

Explanation

Acceptance testing must be conducted by qualified, licensed personnel authorized under the state regulations, typically a licensed elevator mechanic or inspector. General building staff and sales personnel lack the license and qualification. The test verifies code compliance before the unit is placed in service.

Question 4Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Before a new elevator is placed in service in Massachusetts, which certificate must be issued following a satisfactory inspection?

  1. A certificate of inspection and operation Correct answer.
  2. A manufacturer's conformity declaration
  3. A certificate of occupancy for the elevator
  4. A building department zoning certificate

Explanation

After a satisfactory inspection, the authority issues a certificate of inspection that authorizes operation of the elevator. A certificate of occupancy applies to buildings, not individual elevators. Manufacturer declarations and zoning certificates do not authorize elevator operation.

Question 5Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic notices the existing elevator machine room has no lock and is accessible to building tenants. Under Massachusetts requirements, how should this be addressed?

  1. Post a warning sign and continue operation
  2. Install a camera and keep the door unlocked
  3. Leave it open because tenants have a right of access
  4. Secure the machine room so access is limited to authorized personnel Correct answer.

Explanation

Machine rooms and spaces containing elevator equipment must be secured against unauthorized access. Signs or cameras do not satisfy the access-control requirement. Only authorized personnel should be able to enter the machine space.

Question 6Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Which of the following best describes the scope of the Massachusetts Board of Elevator Regulations regarding conveyances?

  1. They apply only to passenger elevators in state buildings
  2. They cover elevators, dumbwaiters, escalators, and similar conveyances Correct answer.
  3. They cover only equipment installed after the year 2000
  4. They apply only to new installations, not existing equipment

Explanation

The regulations govern elevators, dumbwaiters, escalators, moving walks, and similar conveyances across the state, not just public buildings. Both new and existing equipment fall within scope. Limiting coverage to a single building type or installation date misstates the regulatory reach.

Question 7Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

During a periodic inspection, an inspector finds the elevator's pit is being used to store janitorial supplies. What is the correct action?

  1. Allow storage if the items are nonflammable
  2. Approve storage if a shelf is installed
  3. Require removal of the stored materials from the pit Correct answer.
  4. Permit storage only during business hours

Explanation

Elevator pits must be kept clear of stored materials because they obstruct access and create hazards for mechanics and passengers. Flammability, timing, or shelving does not make storage acceptable. The pit is a working space, not a storage area.

Question 8Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A building owner plans to change the rated speed of an existing elevator from 200 to 350 feet per minute. What does this change require under Massachusetts rules?

  1. Only a maintenance log entry
  2. An alteration permit and subsequent inspection Correct answer.
  3. No action because speed is not regulated
  4. Notification to the fire department only

Explanation

Increasing rated speed changes the equipment's operating characteristics and is an alteration requiring a permit and inspection. A log entry or fire department notice does not authorize the change. The work must be reviewed and tested before the unit returns to service.

Question 9Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Which condition must be verified before an elevator is returned to service after a major alteration?

  1. The alteration has passed the required inspection and testing Correct answer.
  2. The owner has renewed the maintenance contract
  3. The building directory has been updated
  4. The car interior has been repainted

Explanation

After a major alteration, the unit must pass the required inspection and testing before it may be placed back in service. Cosmetic work, contracts, and signage are unrelated to safety approval. The inspection confirms the altered equipment meets code.

Question 10Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

An escalator in a Massachusetts retail store has a broken comb plate tooth. What is the appropriate regulatory response?

  1. Reduce the speed and keep running
  2. Take the escalator out of service until the comb plate is repaired Correct answer.
  3. Place a caution cone at the top landing and continue
  4. Continue operation until the next annual inspection

Explanation

A damaged comb plate is a safety hazard at the step-to-landing interface and requires the escalator be removed from service until repaired. Deferring to the next inspection or merely posting warnings leaves the hazard in place. Speed reduction does not correct the defect.

Question 11Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is testing the final limit switch on a traction elevator during an inspection. What is the purpose of this device?

  1. To level the car with the floor
  2. To slow the car as it approaches a landing
  3. To open the doors at the top landing
  4. To stop the car if it travels beyond the normal terminal stopping point Correct answer.

Explanation

The final limit switch is a backup protective device that stops the car if normal terminal stopping fails and the car overtravels. It does not perform normal slowdown, leveling, or door operation. Its function is to prevent the car from striking the overhead or pit.

Question 12Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

During a Category 1 periodic inspection, which item is typically verified for a hydraulic elevator?

  1. The color of the car operating panel
  2. The brand of the hydraulic fluid
  3. The style of the hall fixtures
  4. The operation of the pressure relief valve and tank condition Correct answer.

Explanation

Periodic inspection of hydraulic elevators includes verifying the pressure relief valve functions and the tank and oil condition are acceptable. Cosmetic attributes such as panel color, fluid brand, and fixture style are not safety inspection items. These checks confirm the hydraulic system will not overpressurize.

Question 13Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A building adds a new floor and the existing elevator must now serve it. What regulatory step is required before the extended elevator can carry passengers?

  1. A manufacturer's service bulletin
  2. Only a maintenance log update
  3. A verbal approval from the building inspector
  4. An alteration permit, inspection, and new certificate Correct answer.

Explanation

Extending an elevator to serve a new floor is an alteration that requires a permit, inspection, and updated certificate before passengers may be carried. Log updates, verbal approvals, and bulletins do not provide authorization. The change affects travel, stopping, and safety devices.

Question 14Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Who may witness and certify the periodic safety test of an elevator in Massachusetts?

  1. The building owner
  2. The property manager
  3. A licensed elevator mechanic or authorized inspector Correct answer.
  4. Any licensed electrician

Explanation

Periodic safety tests must be witnessed and certified by licensed elevator personnel or authorized inspectors. Owners, electricians, and property managers lack the specific elevator qualification. The witness confirms the test was performed per code.

Question 15Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

An inspector observes that the elevator car's emergency telephone does not connect to a monitored location. What is the required outcome?

  1. The deficiency must be corrected before the certificate is issued or renewed Correct answer.
  2. The building may rely on cell phone coverage instead
  3. The telephone can be replaced at the next annual inspection
  4. The elevator may remain in service if a sign is posted

Explanation

Two-way communication from the car to a monitored location is a required safety feature, and a nonworking phone is a deficiency that must be corrected before certification. Signage or cell coverage does not substitute for the required communication means. Deferring the repair is not permitted.

Question 16Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Which of the following installations is exempt from the Massachusetts elevator regulations?

  1. An escalator in a shopping mall
  2. A stairway chairlift in a private single-family residence Correct answer.
  3. A freight elevator in a warehouse
  4. A passenger elevator in a new office building

Explanation

Certain conveyances in private single-family residences, such as stairway chairlifts, fall outside the regulated scope. Commercial passenger elevators, freight elevators, and escalators are covered. The exemption turns on the private-residence use, not the equipment type alone.

Question 17Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic finds the governor on a traction elevator has never been tested for grip. What is the appropriate action?

  1. Wait for the next five-year test
  2. Assume it works because the elevator runs
  3. Perform the required governor test and document the result Correct answer.
  4. Disconnect the governor to avoid nuisance trips

Explanation

The governor is a critical overspeed protective device and must be tested to confirm it will grip and set the safety. Assuming function or waiting for a later test leaves the device unverified. Disconnecting it defeats a safety function and is prohibited.

Question 18Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

During a test, a mechanic finds the elevator's door reopening device fails to detect an object in the doorway. What does this condition require?

  1. Operation only during off-peak hours
  2. Continued operation with a caution sign
  3. Removal from service until the reopening device is repaired Correct answer.
  4. Reduced door closing speed only

Explanation

A door reopening device that fails to detect obstructions is a passenger safety hazard and requires the elevator be taken out of service until repaired. Signs, scheduling restrictions, or speed reduction do not correct the failure. The device must reliably reverse the doors on obstruction.

Question 19Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A building owner wants to install a new dumbwaiter between floors of a restaurant. Which statement is correct under Massachusetts rules?

  1. A permit is needed only if the dumbwaiter exceeds 100 pounds capacity
  2. Only the electrical permit is needed
  3. A permit and inspection are required as for other conveyances Correct answer.
  4. Dumbwaiters are unregulated and need no permit

Explanation

Dumbwaiters are conveyances within the scope of the regulations and require permits and inspections just like elevators. They are not exempt, and a weight threshold does not remove the requirement. Electrical permits alone do not authorize installation.

Question 20Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

An inspector finds that the elevator's machine room temperature exceeds the manufacturer's limit because the cooling unit failed. What is the appropriate regulatory action?

  1. Allow operation if a fan is added temporarily
  2. Reduce the elevator speed to compensate
  3. Require correction because excessive temperature can impair equipment safety Correct answer.
  4. Ignore it because temperature is not addressed by code

Explanation

Machine room environmental conditions affect the reliable operation of controls and machinery, and excessive temperature is a deficiency requiring correction. Ignoring it or adding a fan does not restore proper conditions. Speed reduction does not address the underlying equipment risk.

Question 21Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is asked to install a new elevator controller that changes the elevator from relay logic to a microprocessor system. What classification does this work carry?

  1. A repair exempt from permits
  2. An alteration requiring a permit and inspection Correct answer.
  3. A cosmetic upgrade
  4. Routine maintenance

Explanation

Replacing the control system changes the elevator's operating characteristics and is classified as an alteration requiring a permit and inspection. It is not routine maintenance or an exempt repair. The new controller must be tested before the unit returns to service.

Question 22Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

An elevator is involved in an incident in which a passenger is injured. What is the mechanic's regulatory obligation regarding reporting?

  1. Report only to the insurance carrier
  2. Wait until the next inspection to mention it
  3. No report is needed if the elevator still runs
  4. Report the incident to the state authority as required by regulation Correct answer.

Explanation

Accidents involving elevators must be reported to the state elevator authority as required by regulation so the cause can be investigated. Reporting only to an insurer or waiting for the next inspection does not satisfy the obligation. The equipment may also need to be taken out of service pending investigation.

Question 23Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A contractor proposes to install an elevator whose safety code edition differs from the edition adopted by Massachusetts at the time of installation. How should this be resolved?

  1. Install to the code edition adopted by the state for that installation Correct answer.
  2. Use whichever edition the manufacturer prefers
  3. Use the older edition because it is less costly
  4. Defer to the building owner's choice of edition

Explanation

The code edition adopted by the state at the time of installation governs, regardless of manufacturer preference or cost. The authority having jurisdiction enforces the adopted edition. Owner preference cannot override the adopted code.

Question 24Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

During an inspection, a mechanic discovers that the car safety device on a traction elevator was never drop-tested after installation. What is the correct course of action?

  1. Rely on the manufacturer's certification in place of testing
  2. Test only the governor and skip the safety
  3. Place the unit in service and schedule the test later
  4. Perform the required safety test before the unit is approved Correct answer.

Explanation

The car safety must be tested to confirm it will stop and hold the car as designed before the unit is approved. Deferring the test, relying on certification, or testing only the governor leaves the safety unverified. Both the governor and the safety must function together.

Question 25Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is evaluating whether a planned repair to a hydraulic elevator's plunger constitutes an alteration. Which factor is most relevant to the determination?

  1. Whether the work changes the equipment's operating characteristics or safety Correct answer.
  2. The color of the replacement part
  3. The day of the week the work is scheduled
  4. The cost of the repair relative to the building value

Explanation

Whether work is an alteration depends on whether it changes the equipment's operating characteristics or affects safety, not on cost, appearance, or scheduling. A plunger repair that changes performance or safety falls under alteration rules. Purely like-for-like maintenance may not.

Question 26Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

Under the Massachusetts elevator regulations, a mechanic is installing a new traction elevator in a commercial building. Which document must be submitted to the Board before a certificate of inspection is issued for the new installation?

  1. A letter of recommendation from the building's insurance carrier
  2. A property tax certificate for the building where the elevator is installed
  3. A set of construction drawings and specifications signed and sealed by a registered professional engineer Correct answer.
  4. A notarized bill of sale from the equipment manufacturer

Explanation

The regulations require that plans and specifications for new elevator installations be prepared and sealed by a registered professional engineer and submitted for review before installation proceeds. This allows the Board to confirm the design conforms to the adopted safety code before the conveyance is placed in service.

Question 27Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is preparing to perform the required periodic safety test on a traction elevator. Which person is responsible for ensuring the test is actually conducted in accordance with the code?

  1. The building owner's property manager
  2. The elevator manufacturer's regional sales representative
  3. The building's fire safety director
  4. The licensed elevator mechanic performing the test Correct answer.

Explanation

The licensed elevator mechanic who performs the periodic safety test is responsible for conducting it in accordance with the adopted code and for recording the results. Owners and managers may schedule the test, but the technical execution and certification rest with the licensed mechanic.

Question 28Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new hydraulic elevator and must verify the pressure relief valve setting. What is the primary purpose of this valve in the hydraulic system?

  1. To control the descent speed of the car when the pump is stopped
  2. To automatically refill the reservoir when the oil level falls
  3. To limit the system pressure to the design value and prevent overpressure of the cylinder and piping Correct answer.
  4. To regulate the oil temperature during periods of heavy use

Explanation

The pressure relief valve limits hydraulic pressure to the design value so the cylinder, piping, and fittings are not subjected to pressures beyond their rated capacity. It is a safety device against overpressure, not a speed or temperature control.

Question 29Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

During installation of a new escalator, the mechanic must confirm the clearance at the handrail entry point. What is the purpose of the handrail entry guard or guard device at the balustrade?

  2. To prevent fingers and clothing from being drawn into the handrail entry opening Correct answer.
  3. To illuminate the handrail for visibility
  4. To support the weight of the handrail at the newel end

Explanation

Handrail entry guards are installed at the point where the handrail enters the balustrade to prevent fingers, clothing, and small objects from being caught in the opening. They are a passenger-safety feature required by the escalator code.

Question 30Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new dumbwaiter in a restaurant. Which statement correctly describes a dumbwaiter under the Massachusetts elevator regulations?

  1. It is exempt because it carries only food and supplies
  2. It is regulated only if it travels more than 10 feet
  3. It is regulated only if it has a powered door operator
  4. It is a conveyance subject to the elevator regulations and requires a certificate of inspection Correct answer.

Explanation

A dumbwaiter is a conveyance within the scope of the elevator regulations and is subject to installation permitting, inspection, and certification. The fact that it carries only goods does not remove it from regulation.

Question 31Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new elevator and must provide the required car emergency signal. Where must the emergency signal device be located in the car?

  1. Inside the car within reach of a passenger, including one who is seated or using a wheelchair Correct answer.
  2. At the pit ladder so pit personnel can summon help
  3. In the machine room next to the controller
  4. On the car top so mechanics can reach it during maintenance

Explanation

The car emergency signal must be located inside the car and reachable by passengers, including those who are seated or in a wheelchair. Placing it only in the machine room or pit would not serve passengers trapped in the car.

Question 32Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

During installation of a new traction elevator, the mechanic installs the car safety device. What is the function of the car safety on a traction elevator?

  1. To provide a smooth ride by absorbing vibration
  2. To stop and hold the car in the event of an overspeed or broken suspension member Correct answer.
  3. To lock the car door closed while the car is moving
  4. To level the car at each floor during normal operation

Explanation

The car safety is a mechanical device that grips the guide rails to stop and hold the car when the governor trips due to overspeed or a slack rope condition. It is a primary safety device, not a normal-operation control.

Question 33Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new elevator and is setting up the machine room. Which condition is required for the machine room under the elevator regulations?

  1. The room must have a window for ventilation

  3. The room must be shared with the building's electrical service equipment
  4. The room must be accessible only to authorized persons and kept locked Correct answer.

Explanation

The machine room must be secured so that only authorized persons can enter, and it must be kept locked when not attended. Access control protects against tampering and unauthorized entry to moving machinery and controllers.

Question 34Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new traction elevator and must verify the governor tripping speed. What is the purpose of the governor in the traction elevator safety system?

  1. To measure the load in the car and prevent overload
  2. To hold the car at a landing while passengers board
  3. To control the acceleration rate during starting
  4. To monitor the car speed and, at the tripping speed, trigger the car safety to grip the guide rails Correct answer.

Explanation

The governor continuously monitors car speed and, when the tripping speed is reached, mechanically trips the car safety to grip the guide rails and stop the car. It is the speed-sensing element of the safety system.

Question 35Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new hydraulic elevator and must set the lowering valve. What is the function of the lowering valve in a hydraulic elevator system?

  1. To control the rate of oil flow out of the cylinder so the car descends at a controlled speed Correct answer.
  2. To prevent the car from descending if the pump is running
  3. To maintain the oil level in the reservoir
  4. To relieve excess pressure during the up direction

Explanation

The lowering valve controls the return flow of oil from the cylinder to the reservoir, which governs the descent speed of the car. It is opened by the control system when a down command is given.

Question 36Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new escalator and must verify the skirt guard and deck. What is the purpose of the skirt guard at the sides of the steps?

  1. To illuminate the step treads
  2. To provide a handhold for passengers
  3. To support the weight of the steps
  4. To prevent objects and clothing from becoming caught between the steps and the skirt panel Correct answer.

Explanation

The skirt guard is a smooth, low-friction panel at the sides of the steps designed to prevent objects and clothing from being caught between the moving steps and the skirt. It works with the step-to-skirt clearance requirements in the code.

Question 37Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new elevator and must install the final limit switch. What is the purpose of the final limit switch on a traction elevator?

  1. To open the car door at the top landing

  3. To increase the traction between the ropes and the sheave
  4. To guide the ropes into the counterweight

Explanation

The rope equalizer is a spring-mounted or pivoted device that equalizes tension among the hoist ropes so each rope carries its share of the load. Without equalization, some ropes would carry more load and wear faster.

Question 45Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new elevator and must verify the counterweight. What is the purpose of the counterweight on a traction elevator?

  1. To balance the weight of the car and a portion of its rated load, reducing the power required from the driving machine Correct answer.
  2. To guide the car along the hoistway
  3. To provide emergency braking if the car overspeeds
  4. To absorb vibration from the car

Explanation

The counterweight balances the weight of the car plus a portion of the rated load, so the driving machine only has to overcome the unbalanced load and friction. This reduces the required motor power and improves efficiency.

Question 46Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new elevator and must verify the car frame and platform. Which condition must be met for the car frame under the elevator regulations?

  1. The car frame must be capable of supporting the rated load and the weight of the car and its components Correct answer.
  2. The car frame must be removable without disassembling the hoistway
  3. The car frame must be made of aluminum to reduce weight
  4. The car frame must be welded to the guide rails

Explanation

The car frame and platform must be designed and constructed to support the rated load plus the dead weight of the car and its components with the required factor of safety. The material and attachment details are governed by the code, not by convenience.

Question 47Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new elevator and must verify the guide rails. Which condition must be met for the guide rail installation under the elevator regulations?

  1. The guide rails must be lubricated with grease on the safety gripping surfaces
  2. The guide rails must be securely fastened to the hoistway structure and aligned so the car and counterweight travel smoothly Correct answer.
  3. The guide rails must be installed only after the car is placed on them
  4. The guide rails may be supported by the building's plumbing risers

Explanation

Guide rails must be securely fastened to the building structure and aligned to guide the car and counterweight smoothly and to provide a surface for the safety to grip. Supporting rails on unrelated building systems or lubricating the gripping surfaces would compromise safety.

Question 48Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new hydraulic elevator and must verify the rupture valve. What is the purpose of the rupture valve in a hydraulic elevator system?

  1. To stop the descent of the car if the piping or cylinder fails and oil flow exceeds the set rate Correct answer.
  2. To control the normal descent speed of the car
  3. To relieve excess pressure during the up direction
  4. To maintain the oil level in the reservoir

Explanation

The rupture valve senses excessive oil flow, as would occur if the piping or cylinder ruptured, and closes to stop the car from descending uncontrolled. It is a protective device against a catastrophic loss of hydraulic fluid.

Question 49Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new escalator and must verify the step chain. Which condition must be met for the step chain installation under the escalator code?

  1. The step chain must be replaced every year regardless of wear
  2. The step chain must be adjusted so the steps are loose on the track
  3. The step chain must be lubricated with grease on the sprocket teeth only
  4. The step chain must be tensioned so the steps remain engaged with the comb and the chain does not sag excessively Correct answer.

Explanation

The step chain must be properly tensioned so the steps stay aligned with the comb plates and track and the chain does not sag or jump the sprocket. Tensioning also affects the step-to-skirt clearance and the smoothness of operation.

Question 50Elevator construction, installation, alteration, and operation (scope of Board of Elevator Regulations)

A mechanic is installing a new elevator and must verify the machine room ventilation. Which condition must be met for machine room ventilation under the elevator regulations?

  1. The machine room must be ventilated only by the hoistway vents
  2. The machine room must have a window that opens to the outdoors
  3. The machine room must be provided with ventilation to keep the temperature within the range specified for the equipment Correct answer.
  4. The machine room must be sealed and air-conditioned at all times

Explanation

The machine room must be ventilated so the ambient temperature stays within the range specified for the controller and driving machine. Excessive heat can cause nuisance trips and premature component failure, so the ventilation must be adequate for the equipment installed.
