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.
4. Blocking large portions of the rear baffle will change the airflow pattern in
the enclosure causing turbulence. (Do not install equipment against the
rear baffle, as this will affect airflow).
5. Do not work in this enclosure without the exhaust system running.
6. Applications involving acid use in this enclosure is prohibited.
7. Radioisotope materials are prohibited in this enclosure. Consult your
Safety Officer.
8. Avoid cross drafts and limit traffic in front of the enclosure. Air
disturbances created may draw contaminants out of the enclosure.
9. A qualified certification technician should test the enclosure before it is
initially used. The enclosure should be validated whenever it is relocated.
10. The use of safety goggles, protective clothing, gloves and any other
personal protective equipment recommended by your safety officer should
be used.
11. The doors should remain closed during particulate generating processes.
12. The enclosure should be recertified whenever it is serviced or at least
annually thereafter.
13. The HEPA filter provides personnel and environmental protection from
particulate matter. Because room air is drawn into the work area during
operation, this enclosure should not be used for operations requiring
product protection from environmental contamination.
