Chapter 5: Using Your Protector Fume Hood
• Wear a long sleeved lab coat and rubber gloves.
Use protective eyewear. Wear a protective
mask if appropriate.
Loading Materials and Equipment
• Only load the materials required for the
procedure. Do not overload the hood.
• Do not obstruct the rear baffle slots.
• Large objects should not be placed close
together. Objects should be spaced above the
floor to permit airflow to sweep under the
equipment.
• After loading the hood, wait one minute to
purge airborne contaminants from the work
area.
Work Techniques
• Keep all materials at least 6 inches inside of the
sash, and perform all contaminated operations
as far to the rear of the work area as possible.
• Segregate all clean and contaminated materials
in the work area.
• Avoid using techniques or procedures that
disrupt the airflow patterns of the hood.
Final Purging
• Upon completion of work, the hood should be
allowed to operate for two to three minutes
undisturbed, to purge airborne contaminants
from the work area before shutting down
blower.
Unloading Materials and Equipment
• Objects in contact with contaminated material
should be surface decontaminated before
removal from the hood.
• All open trays or containers should be covered
before being removed from the hood.
Shutdown
• Turn off the fluorescent light and hood blower,
then close the sash.
