All multiple dwellings shall comply with the
provisions of this article.
Air conditioning systems shall meet the following
requirements:
A.
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.
B.
Stairways, shafts, hoistways or attics shall not be
used as plenum chambers.
C.
Ducts shall be securely fastened in place and appropriately
fire-stopped.
D.
Filters shall be installed and maintained so as not
to constitute a fire or smoke hazard.
E.
Ducts passing through or located within combustible
construction shall be separated from such construction by a clearance
of at least 1/2 inch or by a noncombustible insulating material at
least 1/4 inch thick.
F.
Air required for ventilation shall be taken from the
exterior or shall be quality controlled.
G.
Exhaust air from a dwelling 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.
H.
Enclosures or spaces where heat, 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.
A.
Air intake and exhaust openings shall be installed,
located and maintained so as not to constitute a hazard or nuisance,
so as to prevent the possibility of fire, smoke, fumes or foreign
matter being drawn into the system.
B.
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.
C.
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.
D.
Exhaust openings shall be located so that the exhaust
air will not create a nuisance.
A.
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 location outside
the fan room.
B.
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.
C.
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.
