ASHRAE Statement on airborne transmission of SARS-CoV-2

ASHRAE Statement on airborne transmission of SARS-CoV-2:

• Transmission of SARS-CoV-2 through the air is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including the operation of HVAC systems can reduce airborne exposures.

ASHRAE Statement on operation of heating, ventilating and air-conditioning systems to reduce SARS-CoV-2 transmission:

• Ventilation and filtration provided by heating, ventilating and air-conditioning systems can reduce the airborne concentration of SARS-CoV-2 and thus the risk of transmission through the air. Unconditioned spaces can cause thermal stress to people that may be directly life threatening and that may also lower resistance to infection. In general, disabling of heating, ventilating and air conditioning systems is not a recommended measure to reduce the transmission of the virus.

Transmission Through Air in Toilet Rooms

Studies have shown that toilets can be a risk of generating airborne droplets and droplet residues that could contribute to transmission of pathogens.

  • Keep toilet room doors closed, even when not in use.
  • Put the toilet seat lid down, if there is one, before flushing.
  • Vent separately where possible (e.g. turn exhaust fan on if vented directly outdoors and run fan continuously).
  • Keep bathroom windows closed if open windows could lead to reentrainment of air into other parts of the building.
