Current through Register Vol. 51, page 10, July 15, 2024
The ventilating systems must maintain temperatures, minimum
				  air changes of outdoor air an hour, minimum total air changes, and relative
				  humidities as follows:
(1) For all
				occupied areas, the facility shall be able to maintain a minimum temperature of
				75 degrees Fahrenheit or 23.9 degrees centigrade at winter design conditions
				with a minimum of at least two total air changes an hour. Each air supply and
				air exhaust system must be mechanically operated. Any outdoor ventilation air
				intake, other than for an individual room unit, shall be located as far away as
				practicable but not less than 25 feet or 7.62 meters from any plumbing vent
				stack and the exhaust from any ventilating system or combustion equipment. The
				bottom of any outdoor intake serving a central air system must be located as
				high as possible but not less than three feet or 0.91 meters above the ground
				level. Each mechanical ventilation system must be designed and balanced to
				provide make-up air and safe pressure relationships between adjacent areas to
				preclude the spread of infections and assure the health of the occupants. Each
				room supply air inlet, recirculation inlet, and exhaust air outlet must be
				located with the grill or diffuser opening not less than three inches or 0.08
				meters above the floor. A corridor may not be used to supply air to or exhaust
				air from any room, except that air from a corridor may be used to ventilate a
				bathroom, a toilet room, or a janitor's closet opening directly on the
				corridor. Mechanical exhaust ventilation must be provided in all soiled areas,
				wet areas, toilet rooms, and clean storage rooms. In any unoccupied service
				area, ventilation may be reduced or discontinued if the health and comfort of
				the occupants are not compromised;
(2) Each cooking appliance, other than a
				microwave oven, must be provided with exhaust ventilation to the exterior of
				the building to remove cooking odors, heat, and moisture. Each cooking
				appliance installed in a resident room must be equipped with a recirculating
				fan equipped with a charcoal filter or may be exhausted to the exterior to
				remove cooking odors, heat, and moisture;
(3) Each vehicle parking garage must be
				provided with carbon monoxide detection to activate exhaust ventilation of six
				air changes each hour or to open the garage door if the area of the garage is
				under 1000 square feet; and
(4)
				Each crawl space must be provided with mechanical ventilation of at least 0.5
				air changes each day or be provided with open perimeter venting as required by
				the
International Building Code.
