in industrial facilities, commercial institutions, and many other applications where eye and body protection is a concern. As such,

thirty years. These units are relied upon to instantly flush the user's eyes, face or body should a chemical spill occur.

inspected regularly and maintained periodically to assure that they will be available when needed. This Installation, Operation and
Maintenance Guide will assist users and facility maintenance personnel in these activities.
