OSU Fume Hood Program

The chemical fume hood is a primary safety device used to protect laboratory workers from chemical exposure, fires, or explosions. The Fume Hood protects the user from flammable, toxic or offensive chemicals by providing an enclosed work area or barrier between the user and the hazardous material.

If the fume hood needs repaired or certified please contact Service2Facilies at 614-292-HELP or

Other engineering controls used in labs include:

Biological Safety Cabinets (BSCs) - the primary means of containment for working safely with infectious materials and/or aerosol generating procedures. Class II BSCs are designed to provide personnel, product, and environmental protection by using high efficiency particulate air (HEPA) filters in their exhaust and supply systems.

Local Exhaust Ventilation (LEV) sometimes referred to as a snorkel orelephant trunk is an engineering control used to capture low risk airborne contaminates at or near the source and remove them awayfrom the work place.


Employee training must be documented and filed with the Chemical Hygiene Plan. Training is available for fume hoods, biosafety cabinets, and local exhaust ventilation from the EHS online training modules at
