Special service situations:

If moisture or liquid is observed around or under a Master-Bilt cabinet, an immediate investigation
should be made by qualified personnel to determine the source of moisture or liquid. The investigation
made should determine if the cabinet is malfunctioning or if there is a simple housekeeping problem.

Moisture or liquid around or under a cabinet is a potential slip/fall hazard for persons walking by or
working in the general area of the cabinet.

Any cabinet malfunction or housekeeping problem that creates a slip/fall hazard around or under a
cabinet should be corrected immediately.
