Proper use of a fume hood will significantly reduce the risk of being exposed to hazardous chemicals.

The following good work practices should be observed while using fume hoods:

• Make sure the hood is working using an airflow indicator.

• Keep the sash as low as is practical - the sash is a safety shield.

• Keep lab equipment elevated at least one inch off the work surface.

• Keep the hood free from clutter - do not block baffle openings.

• Work at least six inches into the hood.

• Minimize rapid movements in front of the hood, and traffic in and out of the laboratory while you are working.
