How do I know that my building is safe to occupy?

The Office of Facilities in coordination with Yale Environmental Health & Safety (EHS) has reviewed building systems, cleaning protocols, and other related parameters in all buildings at all campus locations. The Office of Facilities and EHS websites contain detailed information on what modifications have been made to building systems (like supply air and filtration), occupancy recommendations, cleaning and disinfecting periodicity, and other important improvements that meet the recommendations of the Centers for Disease Control and Prevention (CDC), the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) as well as guidance and policies issued and developed by the University.
