Safety Precautions
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
if there is a problem with airflow.
Use good housekeeping in the hood at all times. Clean up spills
immediately. Periodically clean enclosure interior.
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, bulky objects such as block
heaters, 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.
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).
Always work with your hands as far back in the enclosure as possible. It
is best to keep all powders, chemicals and apparatus inside the lower air
foil of the enclosure.
Do not work with chemicals in this enclosure without the exhaust system
running.
Perchloric acid use in this enclosure is prohibited.
High-level radioisotope materials are prohibited in this enclosure.
Avoid cross drafts and limit traffic in front of the enclosure. Air
disturbances created may draw contaminants out of the enclosure
.
A qualified certification technician should test the XPert Balance
Enclosure or Protector XVS Ventilation Station before it is initially used.
The enclosure should be validated whenever it is relocated, serviced or at
least annually thereafter.
The use of safety goggles, protective clothing, gloves and any other
personal protective equipment recommended by your safety officer
should be used.
The sash should remain in the down position while using the enclosure.
Proper operation of the enclosure depends largely upon its location and
the operator’s work habits. Consult the references in
Appendix D.
