We get some a fair number of random EHS-related inquiries because of
the popularity of our health/safety web materials and safety-themed
store.  This one we received today sounds a lot like a safety urban
legend:

>Do you have any information that would support the installation of
>green Fluorescent lights above eye wash station, in the event that
>someone got chemicals in there eyes.  I was told the green colour
>light is the only colour the eye picks up upon when partly blinded
>or blurred vision. when this occurs.

My instinct is that the rationale is completely false.  ANSI
Z358.1-2004 does require that the area around a shower/eyewash/hose
be well-lit, but there is nothing about it being green in there as
far as I can tell.   Perhaps there is some confusion about the dye
used to look for corneal abrasions or maybe the concept of marking
safety equipment locations with a light (or having a light and horn
that sound when the unit is activated).

Has anyone seen this green light idea before?  Or know of credible
sources that debunk or support it?

Thanks.
