Flushing Of Emergency Eye Wash Stations
The Occupational Safety and Health Administration (OSHA) requires eye wash stations in all locations where corrosive materials and potentially infectious agents (i.e. blood products, etc.) are used. The American National Standard Institute (ANSI) standard for eyewashes requires weekly flushing of eye wash stations. Frequent flushing will help prevent the colonization of bacteria in these units. Some of the organisms of concern include:
- Legionella spp.
- Pseudomonas spp.
- Acanthamoeba spp.
Environmental Health & Safety requires that all emergency eye washes be flushed weekly for at least 20 seconds or until the water runs clear, whichever is longer. A first time flushing may require 5 minutes or more to achieve clear water. The flow of the eyewash must remove the eyewash outlet caps. When eyewash is not in use, the caps or covers must be in place to keep the unit free of airborne contaminents. A log of the flushing must be maintained.
Eyewash water must be between 60o and 90o Fahrenheit. If you are not sure of the water temperature, or suspect it is too cold or hot, call Facilities at 3-4567 to check the temperature and for any other maintenance the unit may need.
Emergency Eyewashes must also be readily identifiable and unobstructed. Lab equipment or glassware can inhibit access.
If you have any questions or concerns about the use or maintenance of emergency eye wash stations, please call the Occupational Safety Unit at 275-3241.
