Drench Hose Units
Guardian Equipment is the world’s leading manufacturer of emergency eyewash and shower technology and related products for
use in industrial facilities, commercial institutions, and many other applications where eye and body protection is a concern. As such,
Guardian drench hose units and dual purpose eyewash/drench hose units have been installed in thousands of facilities over the past
thirty years. These units are relied upon to instantly flush the user’s eyes, face or body should a chemical spill occur.
Like all Guardian products, our eyewash/drench hose and drench hose units are designed, engineered and manufactured for reliable
performance and exceptional durability. However, like all of our products, they must be installed correctly, operated properly,
inspected regularly and maintained periodically to assure that they will be available when needed. Guardian has developed this
Installation, Operation and Maintenance Guide to assist users and facilities maintenance personnel in these activities.
