Room Ventilation Requirements

There are numerous air change and relative room pressure ventilation requirements depending on how a room is utilized, the age of the facility and the facility type. In general, regulations require air to flow from more clean areas to less clean areas. At the core of this standard is protection from exposure to pathogens and chemicals.

In Texas, air ventilation requirements are established by TDSHS (Texas Department of State Health Services). Subsequently, TDSHS adopts some recommendations of ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers), OSHA (Occupational Safety and Health Administration), NIOSH (National Institute for Occupational Safety and Health) and NFPA (National Fire Protection Association).
