Eyewash Solution

Definition - What does Eyewash Solution mean?

Eyewash solutions are the first safety response in an emergency situation when a person's eye has been exposed to a strong chemical with toxic, corrosive, acidic, or caustic properties. The first 10 seconds after the eye has been exposed to a hazardous substance are critical, especially when that substance is corrosive. The ANSI standard advises flushing the eyes continually for 15 minutes, using eyewash solution flowing at a rate of 0.4 gallons per minute for portable and plumbed eyewash stations.

Eyewash solutions must be close to the body's temperature to be effective. Fluid that is too cold may prevent the worker from flushing for the advised 15 minutes, and fluid exceeding 100 degrees can harm the eyes, exacerbating chemical reactions with the eyes and skin.

Safeopedia explains Eyewash Solution

Eyes are susceptible to several potential hazards encountered in the workplace, such as sand and dust particles, chemicals and vapors from toxic chemicals and substances, and even ultraviolet light. Most workplace environments contain potential eye hazards, which is why national standards are in place to protect individuals’ eyes at work.

Immediate and appropriate treatment is crucial when anyone suffers an eye injury. If these injuries involve chemicals or hazardous materials, emergency eyewash solution should be used. All facilities that contain hazardous substances are required to have eyewash stations installed within close proximity of the chemicals for worker's safety.
