Working in your Protector
ClassMate 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 with knit cuffs and
rubber gloves. Use protective eyewear. Wear a
protective mask if appropriate.
Wipe-Down
• Raise the sash to its full open position.
• If necessary, wipe down the interior surfaces of
the hood with dish soap and glass cleaner and
allow to dry.
Loading Materials and Equipment
• Only load the materials required for the
procedure. Do not overload the hood.
• Do not obstruct the front airfoil, or rear baffle
slots.
• Large objects should not be placed close
together.
• 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.
