CHEMICAL FUME HOOD USE GUIDELINES


The protection provided by laboratory fume hoods is dependent upon two important factors:


PROPER USE

MAINTENANCE OF ADEQUATE AIRFLOW

EHSO conducts annual surveys of fume hoods to ensure adequate airflow is maintained through the hood face. Face velocities should be between 80 and 120 feet per minute (fpm) with a sash height of 12 inches. Hoods that operate below 80 fpm are considered inadequate and should not be used for protection from toxic or volatile materials.
If your hood is inoperable, please call EHSO for an inspection.
