South Dakota Administrative Rules › Title 44 - Department of Health › Article 44:76 - Ambulatory surgery center facilities › Chapter 44:76:11 - Construction standards › Section 44:76:11:19 - Ventilating systems

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
				  humidity as follows:
(1) Operating
				rooms - 68 to 73 degrees Fahrenheit (20 to 22.8 degrees centigrade), three
				outdoor, 15 total, and 20 to 60 percent humidity;
(2) Recovery rooms - at least 70 degrees
				Fahrenheit (21.1 degrees centigrade), two outdoor, six total, and 20 to 60
				percent humidity;
For all other occupied areas, the facility shall be able to
				  maintain a minimum temperature of 75 degrees Fahrenheit (23.9 degrees
				  centigrade) at winter design conditions with a minimum of at least two total
				  air changes an hour and a relative humidity of 20 percent. 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. The mechanical ventilation systems 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.
				  Room supply air inlets, recirculation, and exhaust air outlets shall be located
				  with the grill or diffuser opening not less than 3 inches (0.08 meters) above
				  the floor. Corridors 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.
Laboratories shall be ventilated at a rate of six total air
				  changes an hour. All ventilation air from the laboratory shall be directly
				  exhausted to the outside. If this ventilation rate does not provide the air
				  required to ventilate fume hoods and safety cabinets, additional air shall be
				  provided. A filter with 90 percent efficiency shall be installed in the air
				  supply system at its entrance to the media transfer room. Hoods in which highly
				  radioactive materials are processed shall have a face velocity of 150 feet a
				  minute (0.76 meters a second), have a high-efficiency (99.97%) filter, and each
				  hood shall have an independent exhaust system with the fan installed at the
				  discharge point of the system. Hoods used for processing infectious materials
				  shall have a face velocity of 75 feet a minute (0.38 meters a second).
Cooking appliances, 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.
Crawl spaces 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.
