Fume Hoods
Proper usage of fume hoods is essential for Chemical Safety. The following information is supplied to encourage the safe use of fume hoods:
-
Work at least six inches inside hood.
-
Keep the hood clear of clutter. Keep the amount of material in the hood to a minimum.
-
Lower sash to lowest possible position. Keep the sash between your face and the experiment.
-
Avoid rapid movement in and traffic in front of the hood.
-
Elevate large equipment off the work surface of the hood to improve air flow.
-
Use an airflow indicator (tell tale) such as an eight-inch strip of light material dangling from the sash.
-
Run water in hood drains often to keep drain traps full.
-
Use a safety shield in addition to the hood sash if a danger of explosion is present.
-
Insure adequate illumination inside hood.
-
For most effective fume hood operation, keep laboratory doors closed.
-
If you think that your hood is not functioning properly, call your building's facility coordinator and report the problem so that the repair process can be initiated.
