Chapter 4: High Performance Features & Safety Precautions
Safety Precautions
1. Although the enclosure has been engineered to maintain optimum
operator safety, caution should always be used while working.
Prior to using the enclosure, check to make sure that the exhaust
blower is operating and that air is entering the enclosure at its
specified face velocity. The use of an airflow monitor is
recommended to alert the user to a problem with airflow.
2. Use good housekeeping in the enclosure at all times. Clean up
spills immediately. Periodically clean enclosure interior.
3. Do not overload the work surface with apparatus or work material.
The safe operation of the enclosure is based upon having proper
airflow through the structure. Do not place large objects directly on
the work surface. Instead, elevate the object 3/4" on blocks to allow a
flow of air under the object and into the rear baffle exhaust slots.
Ensure blocks are level and secured in place.
4. Blocking large portions of the rear baffle will change the airflow
pattern in the enclosure causing turbulence. (Do not store
containers or supplies against the rear baffle, as this will affect
airflow).
5. Always work with your hands as far back into the enclosure as
possible. Keep all chemicals, materials and apparatus inside the
lower air foil of the enclosure.
6. Do not work in this enclosure without the exhaust system running.
7. General acid use, as well as Perchloric acid use in this enclosure is
prohibited.
8. High-level radioisotope materials are prohibited in this enclosure.
Consult your Safety Officer.
9. Avoid cross drafts and limit traffic in front of the enclosure. Air
disturbances created may draw contaminants out of the enclosure.
10. A qualified certification technician should test the enclosure before
it is initially used.
11. The use of safety goggles, protective clothing, gloves and any other
personal protective equipment recommended by your safety officer
should be used.
12. The sash must remain in the down position while using the
enclosure to ensure containment.
13. Proper performance of the enclosure depends largely upon its
location and the operator's work habits. Consult the references in
Appendix D.
14. The enclosure should be recertified whenever it is serviced or
relocated and at least annually thereafter.
