Subject: DI water in an eye wash station
Comments: cc: "Celia K. Williams"
I assume you're talking
about a plumbed installation?
In theory, sure,
it *could* be used. As long as you know that the supply line can
supply the requisite 3 gallons of water per minute for 15 minutes,
something that I don't think most DI systems can do. And you're
sure that the water is free of bacteria or other potential
However, DI units need to be taken
off-line periodically to have their filters/exchangers serviced.
Which would take out the water supply for your emergency eyewash
at irregular intervals, which is a Bad Idea. And don't forget the
possible draw on the system when calculating the 3 GPM - if two other
people were drawing on that line in other locations I doubt you could
meet 3 GPM on the eyewash. So overall I'd say No,
Don't. You're much better off tapping into the water supply line
before it gets to the DI unit itself.
you're talking about a 32 oz eye wash bottle or something similar, yes,
you could use DI, but make sure you add a preservative to it and change
the water every 6 months or so. Bear in mind that such wash
bottles are *not* ANSI-compliant, and are insufficient as primary eye
washes. They're better than nothing, but not too much
