Operating the Lights
Your Protector Fume Hood utilizes a factory-wired fluorescent light to illuminate
the hood interior. Simply turn the light switch to “ON” to operate.
Working in your Protector 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 materials required for the procedure. Do not overload the
hood.
• Do not obstruct the front air foil, or rear baffle slots.
• Large objects should not be placed close together and spaced above the
work surface 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.
