of wipe-down procedure will depend on all the agents being handled. Consult your Safety
Office and SafetyCommittee for advice.
4.2.4 Base Plenum
Any liquids accidentally released within the work area will either be contained in the work tray
or will flow over the work surface and into the base plenum which surrounds the perimeter of
the work area. This stainless steel base plenum can be drained by means of the ball valve. In
normal use, the drain valve must be in the closed position.
NOTE: Spill capacities are as per NSF-49.
4.2.5 Visual inspection
When moving other equipment, close the safety cabinet and inspect the safety cabinet for any
signs of damage. When using the safety cabinet, the display has readings to record the
pressure. These readings will indicate the loading on the supply HEPA filter.
