Eyewash station (ANSI Z358.1)

Chemical splashes in the eye can cause damage within seconds, so the equipment must be easy to reach. Guidance generally calls for access within a short, quick walk along an unobstructed path on the same level as the hazard, avoiding steps and doors that could slow the person down. The unit should be located where it is clearly marked and well lit.

There are several types. Plumbed units connect to the water supply, self-contained units hold their own water and need regular refilling and replacement, and personal bottles can give first aid on the way to a proper station but do not replace one. Units need to deliver tepid water, which makes it more likely that a person will keep their eyes open for the full flush, and nozzle covers keep dust out until activated.

Users should hold the eyelids open, roll the eyes, and keep flushing for the full period even if pain eases. Contact lenses should be removed if this can be done easily, and medical attention should follow. The SDS Section 4 gives product-specific first aid, which typically begins with flushing for a stated time and getting medical help.

Stations require maintenance. Plumbed units are usually activated on a regular schedule to clear stagnant water and confirm flow, with records kept, and self-contained units need fluid checks. A site Safety shower is often installed alongside. Splash protection from Chemical splash goggles reduces how often the unit is needed, but never replaces it for a Corrosive or Irritant product.
