Laboratory Hoods

Testing Requirements

Laboratory hoods used to prevent harmful exposures are required to be tested or retested:

Observation of the laboratory hood environment, maintenance, and work practices can provide an indication of proper exposure control performance. For example, if the sash of the hood is left open during operation of the research activity, the hood is likely to reduce its functional effectiveness.

Laboratory fume hood performance can also be compromised by the following factors:

Fume Hood Testing

All fume hood testing is performed by a safety representative. The test performed is a quantitative evaluation - face velocity measurement. The following is a belief description of its procedures.

Biological Safety Cabinet
