Restoring occupancy of existing buildings that were shut down due to the COVID-19 virus or other reasons must be performed with strict safety procedures to mitigate the risk of exposure to infectious diseases, such as COVID-19. 

Several guidelines for this procedure are available.  This technical resources bulletin includes SMACNA’s recommended Guidelines to open existing buildings with more specific emphasis on the building’s HVAC System.  Guidelines from the CDC to wear a face covering, keep at least a 6 ft. social distancing from other people and wash hands regularly (for at least 20 seconds) throughout the day, are very important.
