This is in response to your September 20, 1983, inquiry on behalf of Dr. Malcolm Renfrew of the University of Idaho concerning the Occupational Safety and Health Administration's (OSHA) current face velocity specifications for laboratory fume hoods.
We understand Dr. Renfrew's concerns, however, the only current standards which specify fume hood face velocities (13 carcinogen standards in 29 CFR 1910.1003 - 1910.1016) do not apply to laboratories. These standards are not applicable to laboratories by virtue of the decision by the United States Court of Appeals for the Third Circuit in Synthetic Organic Chemical Manufacturer's Association v. Brennan, 506 F. 2nd 385 (3d Cir. 1974), cert. denied 423 U.S. 830.
