The purpose of this Program is to prevent potential hazardous exhaust exposure to workers and users of hazardous exhaust systems while work is performed near, on or inside hazardous exhaust systems,  including those from cryogenic and refrigerants.

EHS provides inspections of safety features and a cyclic certification of capture velocities as determined by an industrial hygiene risk assessment. EHS also tags faulty hoods as “out of service” (see resource page) while awaiting maintenance by either the owner, or Facilities & Operations.
