How to Maintain and Clean the Emergency Eyewash?

Sep. 19, 2020

Fortunately, workplace accidents involving eye injuries rarely occur-but this does not mean that eyewash stations do not require regular maintenance. In this guide, we will introduce you to some best practices to keep the Eye Wash Station in its best condition so that you can rest assured.

Why is maintenance so important?

Portable Eyewash Emergency Eye Wash is essential in any workplace where hazardous and corrosive substances are handled. Using eyewash in emergency situations can help prevent scars, permanent injuries, and blindness.

Improper maintenance can cause many dangers, which we will introduce in detail below.

infectious disease

Bacteria, amoeba, and other disease-causing organisms thrive in stagnant water. If the eyewash is not regularly flushed and activated for testing purposes, the water in the system will begin to accumulate organisms such as Legionella, Pseudomonas, and Acanthamoeba, which may cause conjunctivitis if pushed into the eye. Kind of nasty infection.

If the user’s eyes are damaged (after all, this may be the reason they used the eyewash in the first place), the risk of infection is greater.


Over time, ferrous metals in contact with water tend to oxidize or rust. This will not only cause contamination of the water used in the eyewash but also damage the equipment itself.

Corrosion may create holes in the pipes that supply water to the eyewash unit, leading to leaks, causing the eyewash to drain water when the pressure is insufficient, thereby impairing its ability to properly flush the user's eyes.


Sometimes, dust, dirt, and foreign matter can accumulate in the eyewash station, especially when it is not used for a long time. These fragments can cause contamination and cause pipeline blockage.

Blockages can hinder the flow of water into the equipment, or conversely increase the pressure, and sometimes even reach a level that may harm the user’s eyes.

In ANSI regulations, as well, when it comes to emergency eyewashes, state units must be tested regularly and there are various other agencies that have good reason to guide.

Regular testing can not only ensure the normal operation of the equipment, but also prevent the water in the equipment from standing and stagnating, and it can also flush all debris collected in the pipeline.

In addition to the weekly functional tests required by ANSI regulations, it is recommended that all eyewash units be visually inspected weekly to ensure they are free of debris and maintained in good cleanliness.

The water stored in the portable eyewash should be changed at least every 120 days. The water should also be treated with preservatives to help prevent the growth of microorganisms. All portable eyewashes come with preservatives.

cleaning supplies

As with any safety equipment, keeping the eyewash station clean and hygienic is essential. This will prevent the accumulation of harmful, infectious microorganisms.

When cleaning the eyewash, please use a simple household detergent and hot water solution. Before rinsing thoroughly, apply the solution to the device with a soft sponge or cloth and make sure to remove all the remaining soap.
