Safety Precautions
1. Although the enclosure has been engineered to maintain optimum operator
safety, caution should always be used while working inside the enclosure.
Prior to using, check to make sure that the exhaust blower is operating and
air is entering the enclosure at its specified face velocity.
2. Use good housekeeping in the enclosure at all times. Clean spills
immediately. Periodically clean the enclosure interior with mild soap and
water.
3. Do not store containers or supplies against the rear baffle, as this will affect
airflow. Blocking large portions of the rear baffle will change the airflow
pattern in the enclosure causing turbulence.
