Technical issues regarding how to ensure the quality of water in eye wash stations on-site

The eye washer is installed at the customer’s site and is used only when chemicals splash into employees’ eyes, face, or other parts of their bodies. Under normal circumstances, it isn’t used, as there aren’t that many accidents occurring. If an eye washer is not used for an extended period of time, the quality of the water in the supply pipes and within the eye washer itself will definitely deteriorate, rendering it unsuitable for use. How can this situation be improved? 1. Periodic discharge of the water inside the eye washer: Once a week, someone should turn on the washing switch and the spraying switch of the eye washer for about 1 minute; this allows the old water stored inside the eye washer to be discharged and also helps to check whether the eye washer is functioning properly. However, relying on manual inspection has certain limitations; if the inspector merely makes notes without actually operating the water supply inside the eyewash station, it is of no use. 2. Install a timed drainage device on the eye washer to discharge a certain amount of water at regular intervals each day; it is quite difficult to fake electronic devices. The above two methods are provided for your reference. One additional point: whether it is the water used for normal operation of the eye washer or the water used for testing it, any water that comes out of the eye washer is considered wastewater, but it is not necessarily polluted water. @*aofee @zero424 @zxz017 @Xiao Jie @Chemical Soldier
That makes sense. When I check the eye-washing facilities in our workshop, some of them are in good condition, while others have not been used for a long time; when checked occasionally, it turns out that the water quality there is poor
I’ve been to some sites where, when the eye wash stations were turned on, the water coming out was yellow – how is it possible to use such water for washing the eyes? Since an eye washer has been installed, it should be made to function properly. It would be tragic if we only realize that it isn’t usable when we actually need to use it.
Yes, this is a management issue – responsibilities are not clear and things are not implemented properly. Even the best eye washers cannot function properly without regular maintenance
What types of chemicals require eye wash stations, and are there any relevant regulations? Thank you
For toxic and harmful chemical substances, an eye washer can be used
