Fumehoods, Biosafety Cabinets, and HVAC

Many labs utilize fumehoods, biosafety cabinets, or other local exhaust ventilation to maintain a safe & healthy atmosphere within the lab space and to protect the research from cross contamination. OHIO has special hoods or ventilation devices available such as perchloric hoods and Atomic Absorber vents. All lab fumehoods and biosafety cabinets must be registered with EHS. All fumehood filters in place should be maintained and changed regularly. Any duct-less hoods must be approved by EHS prior to purchase and use, and filters should be maintained and changed regularly. Lab room differential pressure (e.g. negative pressure) is acceptable. Lab air should be relatively odor-free.
