Working in your Protector
Perchloric Acid Fume Hood
Planning
• Thoroughly understand procedures and
equipment required before beginning work.
• Arrange for minimal disruptions, such as room
traffic or entry into the room while the hood is
in use.
Start-up
• Turn on fluorescent light and hood blower.
• Slowly raise the sash.
• Check the baffle air slots for obstructions.
• Allow the hood to operate unobstructed for 5
minutes.
• 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 Perchloric acid materials required
for the procedure. Do not overload the hood.
• Radioisotope materials are not recommended
for use in this Perchloric Acid Hood. Consult
your Safety Officer should you have any
questions.
• Do not obstruct the front air foil, or rear baffle
slots.
• Large objects should not be placed close
together and spaced above the liner bottom 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.
