at the discretion of the state elevator inspector. 

(3) Subsequent Tests: A safety test with no contract-load shall be made in the presence of the 
state elevator inspector, once a year, or as otherwise specified by other sections of 524CMR or 
M.G.L. c- 143, § 64 of all safety devices and equipment to determine that they function as 
required by the applicable codes. It is further required that every fifth year a full-load safety test 
be conducted in the presence of the state elevator inspector. (Refer to 524 CMR 11.00 for 
elevators placed out of service.) 

(4) Car and counterweight safeties and governors shall be tested as follows: Governor operated 
instantaneous type safeties or sliding type safeties of elevators shall be tested at rated speed by 
tripping the governor by hand. The governor shall be separately tested for tripping speed. 

(5) Each governor shall be sealed directly after testing by the state elevator inspector conducting 
the test. No person other than a state elevator inspector, shall break or remove the seal. 

(6) The application of a safety having no speed governor shall be obtained by a free drop test 
which may be made without detaching the ropes. 

(7) . Car and counterweight oil buffers, if any, shall be tested annually with no load on the 
platform at rated car speed, and with a full contract load every fifth year. 

(8) Contract load test for hydraulic elevators: A contract load test under the supervision of the 
state elevator inspector shall be made of every hydraulic elevator or dumbwaiter before the 
equipment is placed in regular service. 

(a) The test shall be made with no load and a test with full rated load on the car in order to 
determine the car speed under each specified condition of loading in both the up and down 
directions. 

(b) A test check of the working pressure including, in case of pressure tanks, a check of 
the accuracy of the tank pressure gauge. 

(c) A test of the relief valve by-pass pressure shall be made in accordance 524 CMR 
17.23(6). 

(d) After the test of the relief valve setting and system pressure test, the following test shall 
be performed and witnessed by a Massachusetts licensed elevator inspector employed by the

524: BOARD OF ELEVATOR REGULATIONS 



8.01: continued 

5. Compute the volume of oil loss as a result of the car movement as follows: 
V = 3.1416 xR^xL 

Where: 

V = volume of oil in cubic inches 
R = radius of plunger (in.) 
L = movement of car (in.) 

6. Compare this to the change in volume in the pit seal collection container and the tank. 
Example: 1 = 7", Plunger diameter = 6" 

V = 3.1416x9x7 =198 in' 
(Note: 231 in3=l U.S. gallon) 

7. If necessary, continue the test to verify the source of the leak. 

8. If it is determined that a leak exists underground, the unit should immediately be 
taken out of service. 

(9) All private residence elevators governed by 524 CMR 23.00 and 35.00 shall be tested and 
inspected every five years. A test with a capacity load will be performed during each test. 

(10) All escalators will be tested with CQntract load at the time of acceptance and will have a 
brake data plate installed. All escalators with brake date plates may be tested thereafter by 
verifying the brake torque. If the environment in which a unit is operating makes the stopping 
capability of the brake questionable, a weight test will be used to reconfirm the torque setting of 
the brake. 

(1 1) All existing escalators without brake data plates or units with more than one driving 
machine will be tested with contract load at five year intervals and whenever the stopping 
capability of the brake is questionable. 

(12) All escalators will require annually a step/skirt performance index test complying with 
A 17. 1-2000 Section 8.6.8.3, and will have up to one year from the date of the citation to be in 
compliance.

(4) Do not attempt to make any repairs. 

(5) Cany no passengers or j&eight while inspections, repairs, or adjustments are in progress, 
and operate the car only in response to directions from the inspector or person m charge. Do not 
move the car when anyone is in the pit or on top of the car except as he may direct. 

(6) When in the opinion of the operator an excess load is to be carried, do not ride or allow 
others to ride on the elevator. 

(7) Hoistway doors or gates shall always be closed and locked before the car is started. The 
car shall be brought to a stop at the landing level before either the car door or car gate where 
provided or the hoist way door or hoistway gate is opened manually. 

(8) Keep car gates closed while car is running, and where no car gates are provided, keep 
passengers away from the open edge of the car platform. 

(9) Limit the number of passengers or load to the contract capacity of the car and do hot permit 
crowding or overloading. 

(10) Do not reverse the operating device suddenly; stop the car before reversing.

(5) The distance between the safety jaws shall not be less than the thickness of the guide rail 
plus 3/32" and the jaws shall not drag against the rail. Where roller or other types of guide shoes 
are used arranged with springs or other means which provide for a definite and limited 
movement of the car or counterweight with respect to the guide rails, minimum clearance 
specified shall be increased by an amount sufficient to prevent the safety jaws from coming in 
contact with the guide rails should the maximum car movement permitted by the guide shoes 
occur. 

(6) Safeties shall be marked by the manufacturer with the range of weight and speed for which 
they are designed; said weight to include the complete car structure, the safety, the contract load 
in the car, and all moving equipment the weight of which is borne by the safety. 

(7) Overspeed instantaneous safeties shall be applied by the governor. On the parting of the 
hoisting ropes governor applied instantaneous safeties shall apply instantly and independently 
of the speed action of the governor. 

(8) No safety shall be permitted for stopping an ascending car or counterweights. 

(9) The governor shall be located where it cannot be struck by the car in case of overtravel and 
where there is sufficient space (that is, not less than eight inches) for full movement of governor 
parts. 

(10) A switch shall be provided on the speed governor and operated by the overspeed action of 
the governor when used with Type B and C car safeties of elevators having a rated speed 
exceeding 125 feet per minute, and when used with counterweight safeties. 

Every car safety shall be provided with a switch operated by the car safety mechanism when 
the safety is applied. 

These switches shall, when operated, remove power from the driving-machine motor and 
brake before or at the time of application of the safety. 

(a) The setting of the car speed-govemor overspeed switch shall conform to the following: 

1. For rated speeds more than 125 feet per minute, up to and including 500 feet per 
minute, the car speed-govemor overspeed switch shall open in the down direction of the 
elevator at not more than 90% of the speed at which the governor is set to trip in the 
down direction. 

2. For rated speeds more than 500 feet per minute, the car speed-governor overspeed 
switch shall open in the down direction of the elevator at not more than 95% of the speed 
at which the governor is set to trip in the down direction. 

3. The switch, when set as specified in either 524 CMR 17.16(10)(a)l. or 
17.l6(10)(a)2., shall open in the up direction at not more than 100% of the speed at 
which the governor is set to trip in the down direction. 

EXCEPTION : The speed-governor overspeed switch may be set to open in the down 
direction of the elevator at not more than 100% of the speed at which the governor is 
set to trip in the down direction, subject to the following requirements: 

A speed-reducing switch of the manually reset type is provided on the governor 
which will reduce the speed of the elevator in case of overspeed, and which shall be set 
to open as specified in 524 CMR 17.16(10)(a)l. and 17.16(10)(a)2. 

Subsequent to the first stop of the car following the opening of the speed-reducing

17.16: continued 



(12) The arc of contact between the governor rope and the driving sheave shall, in conjunction 
with a tension device, provide sufficient traction to cause proper operation of the governor. 

(a) The minimum length of governor jaws shall be such that no serious cutting, tearing, or 
deformation of the rope shall result from the operation of the safety. 

(b) Governor jaws for sliding type safeties shall be so designed that the rope will pull 
through these jaws on the application of a stress exceeding that required to operate so as to 
stop the car. 

(13) Elevators having winding-drum machines shall be provided with a slack-rope device 
which will cut off the power and stop the elevator machine if the car is obstructed in its descent. 
Slack-rope switches shall be constructed so that they will not automatically reset when the slack 
in the rope is removed. 

(14) No car safety which depends on the completion or maintenance of an electric circuit for 
the application of the safety shall be used. Car safeties shall be applied mechanically. 

(1 5) The gripping surfaces of the car or counterweight safeties shall not be used to guide the 
car or counterweights. 

(16) A pawl or ratchet or chisel point safety shall not be used. 

(17) Speed governors shall have their means of speed adjustment sealed after test. If speed 
governors are painted after sealing, all bearing and rubbing surfaces shall be kept free or freed 
of paint and a hand test made to determine that all parts operate freely as intended. Seals shall 
be of a type which will prevent readjustment of the governor tripping speed without breaking 
the seal. 

(18) Each governor shall be sealed directly after testing by the authorized inspector conducting 
the test. No person other than an authorized inspector shall tamper with, break, or remove the 
seal. 

(19) The governor-rope releasing carrier on the car (or on the counterweight) shall be set to 
require a tension in the governor rope, to pull the rope from the carrier, of not more than 60% 
of the pull-through tension developed by the govemor; and the carrier shall be designed so that 
the pull-out tension cannot be adjusted in a normal manner to exceed the amount specified. 

(20) Car safety devices (safeties) are identified and classified on the basis of performance 
characteristics after the safety begins to apply pressure on the guide rails. On this basis, there 
are three types of safeties: 

(a) Ty pe A Safeties . Safeties which develop a r^idly increasing pressure on the guide rails 
during the stopping interval, the stopping distance being very short due to the inherent design 
of the safety. TTie operating force is derived entirely from the mass and the motion of the car 
or the counterweight being stopped. These safeties apply pressure on the guide rails through 
eccentrics, rollers or similar devices, without any flexible medium purposely introduced to 
limit the retarding force and increase the stopping distance. 

(b) Type B Safeties . Safeties which apply limited pressure on the guide rails during the 
stopping interval, and which provide stopping distances that are related to the mass being 
stopped and the speed at which application of the safety is initiated. Retarding forces are 
reasonably uniform after the safety is fiilly applied. Continuous tension in the govemor rope 
may or may not be required to operate the safety during the entire stopping interval. 
Minimum and maximum distances are specified on the basis of govemor tripping speed (see 
524 CMR 17.1 6(1 )(h)). 

(c) Ty pe C Safeties . (Type A with Oil Buffers). Safeties which develop retarding forces 
during the compression stroke of one or more oil buffers interposed between the lower 
members of the car frame and a governor-operated type A auxiliary safety plank applied on 
the guide rails. The stopping distance is equal to the effective stroke of the buffers. 



1/9/98 524 CMR -103 



524: BOARD OF ELEVATOR REGULATIONS 



17.16: continued 



(21) Type C safeties may be used subject to the following requirements: 

(a) The rated speed shall be not more than 500 feet per minute. 

(b) The oil buffers shall conform to all requirements specified in 524 CMR 17.3 1 for oil 
buffers, except that the stroke shall be based on governor tripping speed and on an average 
retardation not exceeding 32.2 feet per second. 

(c) After the buffer stroke, as defined in 524 CMR 17.16(21)(b) has been completed, 
provision shall be made for an additional travel of the plunger or piston of not less than 10% 
of the buffer stroke to prevent excessive impact on the buffer parts and the auxiliary safety 
plank. 

(d) Where the distance between guide rails exceeds eight feet, the safety shall be provided 
with two oil buffers of substantially identical calibration; and the buffers shall be so located 
as to develop minimum stresses in the auxiliary safety plank during safety operation. Buffers 
shall be located in line with and symmetrically between the guide rails. 

(e) The auxiliary safety plank shall be so supported and guided below the car frame that the 
clearances specified in 524 CMR 17. 16(5) for the safety parts are maintained during normal 
operation. The auxiliary safety plank shall be so designed that the maximum stresses in the 
plank shall not exceed those specified for similar car-frame members in 524 CMR 17.13. 

(f) The rail-gripping device of the auxiliary safety plank shall be so arranged and connected 
as to prevent the plank from being out of level more than Vz in the length of the plank when 
the safety is operated to stop the car. 

(g) An electric switch shall be provided and so arranged and connected that the elevator 
cannot be operated by means of the normal operating device if any buffer is compressed more 
than 10% of its stroke. 

(h) Means shall be provided to prevent operation of the elevator by means of the normal 
operating device if the oil level in any buffer is below the minimum allowable level, 

(22) For all type B safeties the movement of the governor rope, relative to the car or the 
counterweight respectively, required to operate the safety mechanism from its fully retracted 
position to a position where the safety jaws begin to exert pressure against the guide rails, shall 
not exceed the following values based on rated speed: 

(a) For Car Safeties: 

200 feet per minute or less ~ 42 inches 

201 to 375 feet per minute - 36 inches 
Over 375 feet per minute - 30 inches 

(b) For Counterweight Safeties: All speeds - 42 inches. 

Drum-operated car and counterweight safeties, requiring continual unwinding of the safety 
drum rope to fully apply the safety, shall be so designated that not less than three turns of the 
safety rope will remain on the drum after the overspeed test of the safety has been made with 
rated load in the car. 

(23) Speed Governor Data Plate . A metal plate shall be securely fastened to all speed governors 
and shall include the following information in legible, permanent figures and letters Va inch in 
height: 

(a) The speed in feet per minute at which the governor is set and sealed to trip the governor 
rope grip jaws. 

(b) The size, material, and construction of the governor rope on which the governor jaws 
were designed to operate.

22. 1 0; Safety Requirements 

22.11: Tests 

22.0 1 : Construction: Protection of Floor Openings 

(1) Floor openings for moving stairways not constituting required means of egress shall be 
protected as follows: 

(2) Floor openings shall be provided with enclosures as required for stairways, or 

(3) In buildings completely protected by an approved automatic sprinkler system, each moving 
stairway floor opening shall be protected against the passage of fire, smoke and gases to the 
story above by one of the following alternative methods of protection: Sprinkler- Vent method 
(524 CMR 22.01(4)); Rolling Shutter method 524 CMR 22.01(5)); or Spray Nozzle method 
(524 CMR 22.01(6)); and, in addition to the manual controls specified, each moving stairway 
shall be provided with an automatic stopping device which will stop the unit when any one of 
the protective methods specified fimctionis. 

(4) S prinkler-Vent method ~ a combination of an automatic water curtain meeting the 
following requirements: 

(a) The exhaust system shall be of such capacity as to create a downdraft, through the 
moving stairway floor opening, having an average velocity of not less than 300 feet per 
minute under normal conditions for a period of not less than 30 minutes. 

NOTE : This requirement can be met by the provision of an air intake from the outside of 
the building above the floor opening. The test of the system under "normal" conditions 
requires that the velocity of the downdraft be developed when windows or doors normally 
used for ventilation are open. The size of the exhaust fan and exhaust ducts must be 
sufficient to meet such ventilation conditions. Experience indicates that fan capacity should 
be based on a rating of not less than 500 cfin per square foot of moving stairway opening to 
obtain the 300 FPM required. If the building is provided with an air-conditioning system 
arranged to be automatically shut down in the event of fire, the test conditions should be met 
with the air-conditioning system shut down. The 300 FPM downdraft through the opening 
provides for the testing of the exhaust system without requiring an expansion of air present 
under actual fire conditions. 

(b) Operation of the exhaust system for any floor opening shall be initiated by an approved 
thermostatic device in the story involved and shall also result from the functioning of other 
required automatic fire detection devices within the building or section of the building. 
There shall also be provided a manual means of operating and testing the system. 
NOTE : Supervised smoke detection devices ordinarily provide earlier detection of fire than 
automatic sprinkler systems and if used to actuate the exhaust system automatically should 
provide an added life-safety advantage. 

(c) To assure reliability of the electrical supply to all parts of the exhaust system and 
control devices, the circuits shall be supplied directly from the bus bars of the main 
switchboard, or by a main connected to the bus bars of the main switchboard but not used 
for any other purpose. 



1/9/98 524 CMR -155

(d) Fans and ducts used in connection with automatic exhaust systems shall be constructed 
and installed in accordance with the best engineering practice. 

(e) Periodic tests, at least quarterly, shall be made of the automatic exhaust system to 
maintain the system and the various control devices in good working order. 

(Q The water curtain shall be formed by open sprinklers or spray nozzles so located as to 
form a complete water barrier along all exposed sides of the door opening and reaching from 
the ceiling to the floor. ^ 

(5) Rolling Shutter method - an automatic self-closing rolling shutter which will completely 
enclose the top of each moving stairway opening above the street floor, meeting the following 
requirements: 

(a) The shutter shall close off the wellway opening immediately upon the automatic 
detection, by an approved device, of either fire or smoke in the vicinity of the moving 
stairway, and in addition there shall be provided a manual means of operating and testing the 
operation of the shutter. 

(b) The shutter assembly shall be capable of supporting a weight of 100 lbs. on any one 
square foot of area, and not less resistant to fire or heat than 24 gauge steel. 

(c) The shutter shall operate at a speed of not greater than 30' per minute and shall be 
equipped with a sensitive leading edge. The leading edge shall arrest the progress of the 
moving shutter and cause it to retract a distance of approximately six inches upon the 
application of a force of at least 20 lbs. applied on the surface of the leading edge. The 
shutter, following retraction, shall continue to closure immediately. 

(d) To assure reliability of the electrical supply to the control devices for, and for actuation 
of, the automatic rolling shutter, the circuits shall be supplied directly from the bus bars of 
the main switchboard, or by a main connected to the bus bars of the main sv^tchboard but 
not used for any other piupose. 

(6) Spray Nozzle method - a combination of an automatic smoke or fire detection system and 
a system of high velocity water spray nozzles, meeting the following requirements: 

(a) Spray nozzles shall be of the open type and shall have a solid conical spray pattern. The 
number of nozzles, discharge angles and location shall be such that the moving stairway 
floor opening' will be completely covered by a dense spray upon the operation of the system. 

(b) The number and size of nozzles and water supply shall be sufficient to deliver a 
discharge of two and one half gallons of water per square foot per minute through the floor 
opening. 

(c) Spray nozzles shall be located near the top of the wellway housing and so positioned 
that the center line of discharge is at an angle not less than 60° with the plane of the opening 
to be protected. 

(d) Spray nozzles shall be provided with a water supply, separate from the water supply 
system for automatic sprinklers, at a minunum flowing pressure of at least 25 lbs. per square 
inch. Oversize piping shall be used to minimize friction loss. 

(e) Control valves shall be readily accessible to minimize water damage. Thermal control 
valves may be used, if piping is arranged and sized so that any one control valve can supply 
simultaneously all the spray nozzles intended for the protection of the moving stairway floor 
opening. 

(f) A noncombustible draft curtain, extending 20" to 30" below and around the opening and 
a solid non-combustible wellway housing above the floor shall be provided at each moving 
stairway floor opening. Spray nozzles shall be protected by sheet metal deflectors against 
mechanical injury. 

(g) Means of manual operation of the spray nozzle isystem for any floor opening shall be 
provided, and the system shall also be actuated by approved smoke detection or thermostatic 
devices in the story in which fire may occur. Supervised smoke detection devices located 
in or near the moving stairway floor opening may be used to meet this requirement. 
Thermostatic fire detection devices, such as rate-of-rise or fixed temperature systems, used 
to initiate the operation of the spray nozzle system shall be so located as to assure the 
operation of the system in advance of the passage of smoke through the moving stairway 
floor opening.

524 CMR 26,00 has been developed in response to demands for a separate section of 524 
CMR to cover the installation of certain elevator equipment in buildings or structures used 
exclusively for the parking of motor vehicles. It was felt that in many such installations, 
particularly where no person rides the elevator during the parking process, reasonable safety 
does not require that the elevators meet all of the requirements of 524 CMR (The Massachusetts 
Elevator Code) for conventional elevator installations. 

26.02: Refere nce to Safety Codes 

Installations shall be in accordance with accepted standards of engineering practice and, 
except as provided herein, shall conform to the minimum requirements of 524 CMR 17.00. In 
case any question arises as to what is the best engineering practice, design, installation and tests

automobiles where, during the parking process, each automobile is moved either under its 
own power, or by means of a power-driven parking device onto and off the elevator directly 
into parking spaces or cubicles in line widi the elevator, where no persons are normally 
employed or stationed, in the parking areas. 

Also, devices used exclusively for the raising of automobiles above, or lowering them 
below, the point of loading automobiles on the device for the purpose of storing them on the 
device itself 

(b) 524 CMR 26.00 does not apply to: The design of the structure, of a crane or similar 
device on which the elevator may be mounted, or the design of any automobile parking dolly 
or mechanism, except the interlocking of the control of such device v«th the elevator control. 

(2) Classification . Elevator equipment subject to 524 CMR 26.00 shall be classified as foUovs^:

8.01: Practical Tests and Inspections 

A practical test of all equipment governed by 524 CMR as required by M.G.L. c. 143, § 64, 
shall consist of the following: , j 

(1 ) The initial "Acceptance Test" and subsequent annual tests and/or inspections shall be made 
of all equipment under the supervision of the state elevator inspector. Such tests shall conform 
to the following Acceptance Test: A contract load test at governing tripping speed where 
applicable shall be made for all new installations. 

(2) Prior to returning to service any equipment which has undergone a major alteration, material 
change, or which has been placed out of service due to non-use, accident or a cause of injury, or 
at the discretion of the state elevator inspector. 

(3) Subsequent Tests: A safety test with no contract-load shall be made in the presence of the 
state elevator inspector, once a year, or as otherwise specified by other sections of 524CMR or 
M.G.L. c. 143, § 64 of all safety devices and equipment to determine that they function as 
required by the applicable codes. It is further required that every fifth year a full-load safety test 
be conducted in the presence of the stale elevator inspector. (Refer to 524 CMR 1 1.00 for 
elevators placed out of service.) 

(4) Car and counterweight safeties and governors shall be tested as follows: Governor operated 
instantaneous type safeties or sliding type safeties of elevators shall be tested at rated speed by 
tripping the governor by hand. The governor shall be separately tested for tripping speed. 

(5) Each governor shall be sealed directly after testing by the state elevator inspector conducting 
the test. No person other than a state elevator inspector, shall break or remove the seal. 

(6) The application of a safety having no speed governor shall be obtained by a free drop test 
which may be made without detaching the ropes. 

(7) Car and counterweight oil buffers, if any, shall be tested annually with no load on the 
platform at rated car speed, and with a full contract load every fifth year. 

(8) Contract load test for hydraulic elevators: A contract load test under the supervision of the 
state elevator inspector shall be made of every hydraulic elevator or dumbwaiter before the 
equipment is placed in regular service. 

(a) The test shall be made with no load and a test with fuU rated load on the car in order to 
determine the car speed under each specified condition of loading in both the up and down 
directions. . '^' ■ 

.(b) A test check of the working pressure including, in case of pressure tanks, a checkof 
: the accuracy of the tank pressure gauge. 

(c) A test of the relief valve by-pass pressure shall be made in accordance 524 CMR 
V^'^V ■,■17.23(6):- :■■■■;;.■■ Vi^ 

(d) After the test of the relief valve setting and system pressure test, the following test shall 
; ' be performed and witnessed by a Massachusetts licensed elevator inspector employed by the 

Department of Public Safety. Cylinders that are not exposed shall be tested as follows: 

1. Note the amount of oil in the pit and seal leak collection container, 

2. Pai'k the elevator at a convenient location and open the main line disconnect. 

3. Mark the level of the oil in the tank. 

4. Wait at least 15 minutes and measure the amount that the car has moved down.

5. Compute the volume of oil loss as a result of the car movement as follows: 
V = 3.1416xR2xL : 

■Where: 

V = volume of oil in cubic inches ; 
R = radius of plunger (in.) 
L = movement of car (in.) 

6. Compare this to the change in volume in the pit seal collection container and the tank. 
Example: 1 = 7", Plunger diameter = 6" : 

V = 3.1416x9x7 = 198 in3 

(Note:231in3=lU.S.gallon) : - . 

7. If necessary, continue the test to verify the source of the leak. 

8. If it is determined that a leak exists underground, the unit should immediately be 
taken out of service. : 

(9) All private residence elevators governed by 524 CMR 23.00 and 35,00 shall be tested and 
inspected every five years. A test with a capacity load will be performed during each test. 

(10) All escalators will be tested with contract load at the time of acceptance and will have a 
brake data plate installed. All escalators with brake date plates may be tested thereafter by 
verifying the brake torque. If the environment in which a unit is operating makes the stopping 
capability of the brake questionable, a weight test will be used to reconfirm the torque setting of 

■ ■' the brake..-/ .■,'■: ' 

(11) All existing escalators without brake data plates or units with more than one driving 
machine will be tested with contract load at five year intervals and whenever the stopping 
capability of the brake is questionable. 

(12) All escalators will require annually a step/skirt performance index test complying with 
A17. 1-2000 Section 8.6.8.3, and wiD have up to one year from the date of the citation to be in 
compliance. 

8.02: Unsafe or Non-compliance Conditions 

If upon inspection any equipment covered by 524 CMR is found in an unsafe condition, or 
not in accordance with the provisions of 524 CMR in effect at the time of its installation, the 
state elevator inspector shall thereupon serve a written notice upon the building owner or lessee, 
^ citing the section of 524 CMR of which said equipment is in violation, stating the action required 
to bring the equipment into compliance, and the date when recommended repairs or changes 
; shall be completed. After the service of such notice, it shall be the duty of the owner to proceed 
within the time allowed to make such to make such repairs as are necessaiy to place the 
equipment in a safe condition. It shall be unlawful to operate such equipment after the date 
stated in the notice unless such recommended repairs or changes have been made and the 
equipment has been approved, or unless an extension of time has been secured from the state 
elevator inspector in writing. 

8.03: Power to Seal Equipment 

The state elevator inspector in addition to any other penalties herein provided, shall have the 
power to seal out of service any device or equipment under his jurisdiction, covered by 524 CMR 
when in the case of emergency in the opinion of the state elevator inspector, such device is in a 
condition to render it unsafe for operation; or for willful failure to comply with 524 CMR. 

8.04: Notice of Sealing Out of Service 

Before sealing any device out of service, the state elevator inspector, except in the case of 
emergency, shall serve written notice upon the building owner or lessee stating intention to seal
