OSHA Quick Facts: Laboratory Safety, Chemical Fume Hoods. The fume hood is often the primary control device for protecting laboratory workers when working with flammable and/or toxic chemicals. OSHAâs Laboratory standard (29 CFR 1910.1450) requires that fume hoods be maintained and function properly when used.
With an estimated 750,000 hoods in use in. the U.S., the aggregate energy use and savings potential is significant. We estimate the. annual operating cost of U.S. fume hoods at approximately $4.2 billion, with a. corresponding peak electrical demand of 5,100 megawatts. There are various strategies. for saving energy, each with its limitations.
