Working in Your Protector Radioisotope
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.

High-level radioisotope materials (gamma particles) are not recommended
for use in this Radioisotope Hood. Only use low-level alpha, lower level
beta radioactive particles, and gaseous radioisotopes. 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.
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.
