For one- and two-family dwellings:
A. Exhaust air from a dwelling unit shall not be circulated to another
dwelling unit.
B. Ducts shall be securely fastened in place and appropriately firestopped.
C. Equipment shall be secured in place so as not to present a hazard.
For multiple dwellings and nonresidential dwellings:
A. Air-conditioning systems.
(1) Refrigerants that are highly flammable shall not be used.
(2) Direct systems using refrigerants that are flammable or toxic shall
not be used for air-conditioning purposes.
(3) Equipment shall be secured in place so as not to present a hazard.
B. Ventilating systems.
(1) Ventilating systems shall be installed and maintained so that the
rapid spread of heat, flame or smoke through the system will be prevented
and so that under conditions of use the temperature of any combustible
material adjacent thereto or in contact therewith will not exceed
a safe temperature.
(2) Stairways, shafts, hoistways or attics shall not be used as plenum
chambers.
(3) Ducts shall be securely fastened in place and appropriately firestopped.
(4) Ducts and other air-handling equipment shall be of noncombustible
material.
(5) Filters shall be installed and maintained so as not to constitute
a fire or smoke hazard.
(6) Air required for ventilation shall be taken from the exterior or
shall be quality-controlled.
(7) Exhaust air from a unit or a space, the contents of which may emit
odors, fumes or vapors, shall not be circulated to other occupied
spaces within the building.
C. Air intake and exhaust openings.
(1) Air intake and exhaust openings shall be installed, located and maintained
so as not to constitute a hazard or nuisance and so as to prevent
the possibility of fire, smoke, fumes or foreign matter being drawn
into the system.
(2) Ventilating systems shall be provided with adequate openings for
incoming and outgoing air to obtain the required circulation. Intake
openings shall provide air from an uncontaminated source.
(3) Where openings for mechanical exhaust are located in spaces that
also contain fuel-burning equipment, there shall be provided fixed
intake openings from the exterior to supply sufficient air so that
the fuel-burning equipment is not adversely affected.
(4) Exhaust openings shall be located so that the exhaust air will not
create a nuisance.
D. Ventilation requirements. Enclosures or spaces where the gases, vapors
or odors may accumulate and become a potential source of hazard or
nuisance shall be provided with adequate means of ventilation to remove
such excess.
E. Safety controls.
(1) Manually operated controls shall be provided to stop the operation
of all central fan equipment. Such controls shall be conspicuously
identified and in readily accessible locations outside the fan room.
(2) Every system using recirculated air and serving an assembly space
or more than one fire area or more than one story of a building shall
be provided with controls arranged so that under abnormal rise in
temperature of the air in the system the fans causing normal circulation
shall stop and require manual restart.
(3) Every system for ventilating an assembly space shall be provided
with an emergency switch conveniently located and with a durable sign
giving instructions for shutting down the system in case of fire.
All fuel-burning equipment, storage facilities, piping, etc.,
shall be installed, used and maintained as required by the New York
State Uniform Fire Prevention and Building Code.
Every person who discards a gas-fired, electric or other refrigerator
shall, before removing such refrigerator from the room in which it
was installed, remove the locking device or hinges of the refrigerator.
No person shall in any manner disconnect, bypass, block or interfere
with any safety device so as to hinder or prevent the normal and effective
operation of said device.
