A.13.1.1.1.2 See M.G.L. c. 48, § 27A. Except as herein after provided, no person shall shut off, disconnect, obstruct, remove or destroy, or cause or permit to be shut off, disconnected, obstructed, removed or destroyed, any part of any sprinkler system, water main, hydrant or other device used for fire protection or carbon monoxide detection and alarm in any building owned, leased or occupied by such person or under his control or supervision, without first procuring a written permit so to do from the head of the fire department of the city or town wherein such building is situated, which permit such head is hereby authorized to issue subject to such terms and conditions as, in his judgment, protection against fire and the preservation of the public safety may require. This section shall not prevent the temporary shutting off or disconnection or partial removal of such a system, main, hydrant or other device for the purpose of making necessary repairs or preventing freezing or other property damage; provided, however, that the head of the fire department is notified immediately of such emergency action. The head of the fire department shall also be notified when the system, main, hydrant or other device is placed back in service. Violation of thissection shall be punished by imprisonment for not more than one year or by a fine of not more than one thousand dollars, or both. The supreme judicial and superior courts shall have jurisdiction in equity to enforce compliance with the provisions of this section.
The property owner shall be responsible for the proper testing and maintenance of the equipment and systems.
Obstructions shall not be placed or kept near fire hydrants, fire department inlet connections, or fire protection system control valves in a manner that would prevent such equipment or fire hydrants from being immediately visible and accessible.
A minimum 36 in. (91 mm) of clear space shall be maintained to permit access to and operation of fire protection equipment, fire department inlet connections, or fire protection system control valves. The fire department shall not be deterred or hindered from gaining immediate access to fire protection equipment.
An approved clear and unobstructed path shall be provided and maintained for access to the fire department inlet connections.
Detailed records documenting all systems and equipment testing and maintenance shall be kept by the property owner and shall be made available upon request for review by the AHJ.
Existing systems shall be in accordance with 1.3.6.2 and 10.3.2.
All fire protection systems and devices shall be maintained in a reliable operating condition and shall be replaced or repaired where defective or recalled.

13.1.8

AMENDMENT
This section has been amended at the state or city level.
No person shall shut off, disconnect, obstruct, remove, and/or modify a fire protection system or carbon monoxide protection system without first procuring a written permit in accordance with Section 1.12 from the AHJ. The AHJ shall be notified when any fire protection system is out of service and on restoration of service.
When a fire protection system is out of service for more than 4 hours in a 24-hour period, the AHJ shall be permitted to require the building to be evacuated or an approved fire watch to be provided for all portions left unprotected by the fire protection system shutdown until the fire protection system has been returned to service.
In the event of a failure of a fire protection system or an excessive number of accidental activations, the AHJ shall be permitted to require an approved fire watch until the system is repaired.
For occupancies of an especially hazardous nature or where special hazards exist in addition to the normal hazard of the occupancy, or where access for fire apparatus is unduly difficult, or where the size or configuration of the building or contents limits normal fire suppression efforts, the AHJ shall have the authority to require additional safeguards consisting of additional fire safety equipment, more than one type of fire safety equipment, or special systems suitable for the protection of the hazard involved.
The AHJ shall have the authority to require locking fire department connection (FDC) plugs or caps on all water-based fire protection systems.
