Illinois Administrative Code › Title 77 - PUBLIC HEALTH › Part 205 - AMBULATORY SURGICAL TREATMENT CENTER LICENSING REQUIREMENTS › Subpart J - MECHANICAL › Section 205.1540 - Air Conditioning, Heating and Ventilating Systems

Current through Register Vol. 48, No. 28, July 12, 2024
a) The systems shall be designed to provide
				the comfort temperatures and humidities as recommended by American Society of
				Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) Standards (see
				Section
				205.115(a)(1)(A)
				 ).
b) Air handling systems shall conform to NFPA
				90A.
c) Heating, air conditioning,
				and ventilating systems for spaces not exceeding 25,000 cubic feet in volume
				shall conform to NFPA 90B, except that return ducts shall be constructed of
				materials equal to that specified for supply ducts, Chapter 2, paragraph
				1.1., Duct
				Materials.
d) Outdoor air intakes
				shall be located as far as practical, but not less than 15 feet, from exhaust
				outlets of ventilation systems, combustion equipment stacks, medical-surgical
				vacuum systems, and plumbing vent stacks, or from areas that may collect
				vehicular exhaust and other noxious fumes.
e) All ventilation air outlets and inlets
				shall conform to NFPA 90A, Chapter 2, paragraph 3.2., Location of Outlets and
				Inlets.
f) The ventilation systems
				shall be designed and balanced to provide the ventilation and pressure
				relationships as shown in Table A.
g) The ventilation air supplied to the
				procedure rooms shall be delivered at or near the ceiling of the area served,
				and all exhaust or return air from the area shall be removed near the floor
				level. At least two exhaust outlets shall be used in each procedure
				room.
h) All central ventilation or
				air conditioning systems shall be equipped with filters having efficiencies not
				less than those specified in the following table:

i)
				All filter efficiencies shall be average atmospheric dust spot efficiencies
				tested in accordance with the ASHRAE Standards 52.1, 52.2, 55, 58, 62, 63.1,
				63.2, 64, and 68.
j) For systems
				serving procedure and recovery rooms, filter bed No. 1 shall be located
				upstream of the air conditioning equipment, and filter bed No. 2 shall be
				located downstream of the supply fan and air conditioning equipment, including
				humidifiers.
k) Filter frames shall
				be durable and shall provide an airtight fit with the enclosing duct work. All
				joints between filter segments and enclosing duct work shall be gasketed or
				sealed to provide a positive seal against air leakage.
l) A manometer shall be installed across each
				filter bed serving procedure and recovery rooms.
m) Fire and smoke dampers shall be
				constructed, located and installed in accordance with the requirements of NFPA
				90A.
n) All systems, regardless of
				size, that serve more than one smoke or fire zone shall be equipped with smoke
				detectors to shut down fans automatically as specified in paragraph 4-3.1 of
				NFPA 90A.
o) The ventilation system
				for anesthesia storage rooms shall conform to the requirements of NFPA 99,
				including the gravity option ventilation system.
p) Boiler rooms shall be provided with
				sufficient outdoor air to maintain combustion rates of equipment and limit
				temperatures in working stations to 97°F Effective Temperature as defined
				by the ASHRAE Handbook of Fundamentals.
q) Rooms containing heat-producing equipment,
				such as boiler rooms and heater rooms, shall be insulated and ventilated to
				prevent any floor surface above from exceeding a temperature of
				100°F.
r) For dates of
				materials incorporated by reference, see Section 205.115.
