Chapter 4: High Performance Features and Safety

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 biohazardous materials, chemicals and apparatus inside the lower air foil of the enclosure.

6.Do not work in this enclosure without the exhaust system running.

7.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. The enclosure should be validated whenever it is relocated.
