Bradley On-Site® Gravity Fed Eye Wash On-Site® is a portable, self-contained eye wash, ideal when plumbing is not available. Water stored above a fluid reservoir assures uninhibited 15-minute flow, even using only half the solution (7 gallons) of other portable units. Unique design consists of a pedestal which houses the water reservoir, spray head assembly and hinged eye tray. The solution tank, made of transparent polycarbonate, shows when to refill or clean. On-Site® weighs 60 pounds filled, has built-in handles for portability when empty, and comes with an 8 oz. bottle of water preservative, safety sign and inspection tag. Meets ANSI Standard Z358.1-1998.
