Current through Register Vol. 51, page 10, July 15, 2024
The ventilating systems shall maintain temperatures, minimum
				  air changes of outdoor air an hour, minimum total air changes, and relative
				  humidities as follows:
(1) All occupied
				areas of the building shall maintain a minimum humidity level of 15% relative
				humidity provided through the building central ventilation system;
(2) Beauty shops shall provide a minimum of
				15 air changes per hour of exhaust ventilation when the room is in
				use;
(3) Toilet and bathing rooms
				shall provide a minimum of 10 air changes per hour of exhaust ventilation;
For occupied areas, the facility shall be able to maintain a
				  minimum temperature of 75 degrees Fahrenheit (23.9 degrees centigrade) and at
				  least 15 percent humidity at winter design conditions with a minimum of at
				  least two total air changes an hour. All air supply and air exhaust systems
				  shall be mechanically operated. All fans serving exhaust systems shall be
				  located at the discharge end of the system. Outdoor ventilation air intakes,
				  other than for individual room units, shall be located as far away as
				  practicable but not less than 25 feet (7.62 meters) from plumbing vent stacks
				  and the exhausts from any ventilating system or combustion equipment. The
				  bottom of outdoor intakes serving central air systems shall be located as high
				  as possible but not less than six feet (1.83 meters) above the ground level or,
				  if installed through the roof, three feet (0.91 meters) above roof level. Each
				  mechanical ventilation system shall 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, and exhaust air outlet shall be located with the
				  grill or diffuser opening not less than three inches (0.08 meters) above the
				  floor. A corridor may not be used to supply air to or exhaust air from any
				  room, except that exhaust air from corridors may be used to ventilate
				  bathrooms, toilet rooms, or janitor's closets opening directly on corridors.
				  Continuous mechanical exhaust ventilation shall be provided in all soiled
				  areas, wet areas, and storage rooms. In unoccupied service areas, ventilation
				  may be reduced or discontinued when the health and comfort of the occupants are
				  not compromised.
Each cooking appliance, other than microwave ovens, shall be
				  provided with exhaust ventilation to the exterior of the building to remove
				  cooking odors, heat, and moisture.
Each vehicle parking garage shall 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.
				  A sign shall be posted at the front of each parking space advising the driver
				  to shut off the engine.
Each crawl space shall be provided with mechanical
				  ventilation at least one half air changes each day or be provided with open
				  perimeter venting as required by the International Building
				  Code.
