Safety Precautions
1. Although the enclosure has been engineered to maintain Class 5 air
conditions, caution should always be used while working. Prior to using
the enclosure, check to make sure that the blower is operating and
periodically ensure that air is flowing through the enclosure at its specified
downflow velocity of 30 to 65 fpm. 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.
4. The Purifier Filtered PCR Enclosures should never be used with
biohazardous materials, toxins, acids, or radionuclides. Air from the work
area is dispersed directly into the laboratory from the enclosure. A
qualified Safety Officer must carefully assess any risk associated with the
use of the Purifier Filtered PCR Enclosure.
5. Always work with your hands as far back into the enclosure as possible.
Keep all materials and apparatus inside the lower air foil of the enclosure.
6. Do not work in this enclosure without the blower running.
7. Perchloric acid use in this enclosure is prohibited.
8. Radioactive 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 disturb Class 5 conditions.
10. A qualified certification technician should test the enclosure before it is
initially used. The enclosure should be validated annually and whenever it
is relocated.
11. The sash must remain in the down position while using the enclosure.
