Eye Wash Filters

A subject I have not previously mentioned (or thought about, for that matter) involves the filters that are in laboratory safety eyewashes.  Yes, there are filters there, and they are designed to keep dust and dirt from the water supply (and piping) from getting into your eyes when you are using the eyewash.

Typically, these are simple mesh or foam pieces that can easily be rinsed or cleaned under running water if there is dust or dirt present.  On the other hand, frequently-used eyewashes (such as with a sink-mounted unit that is also used for rinsing glassware or cleaning the inside of the sink) may need to have the filter checked and cleaned frequently.

Take a few minutes to check your eyewash filter and clean or replace it, if needed.
