Eyewash Stations are an important part of your facilities' emergency plan. Hospeco® Eyewash Stations and refill supplies are engineered to comply with ANSI standards for protection. ANSI Z358.1-2009 Standard. An eyewash station should be installed at "accessible" locations and reachable within ten seconds. Both plumbed and self-contained eyewash stations should deliver a 15 minute continuous flow. These units should be installed wherever caustic or hazardous substances are present. Check all relevant MSDS sheets at your facility to determine if the chemical or substance requires 15 minute eye flushing. An eyewash should have an on-off valve, door or pull strap that activates within one second with one single motion or less. This safety equipment must be located in an area free of obstructions because this could inhibit immediate use. Emergency showers and eyewash stations must have a flushing fluid temperature between 60 F and 100 F.
