Wildfire events can create hazardous air quality. In normal operations, campus buildings can be configured to limit outside air intake during smoke events to reduce the amount of smoke being pulled into a building. Under Covid restrictions, Cal OSHA guidelines require that outside air be maximized until the air quality index reaches 100. At that point, Facilities Services will adjust the building ventilation systems to limit outside air where possible. Some buildings, such as lab buildings, will remain on 100% outside air under all conditions.
