Sebbe, that eyewash system is similar to some that I'm shopping for. My paranoia is pushing me towards a respirator too.
Some of the materials I work with are not too bad on their own, but if accidentally combined, become extremely nasty. I would rather be prepared than find myself in one of those "it will never happen" situations without first-aid.
My mother did histological research in the 60's - she's told me a horror story where a lab tech got splashed with chromic acid (glassware cleaner); there were no showers, eye-washes etc., back then - there was little that could be done except try to wash the victim with a sink-hose,as layers of skin sloughed off - ugh!
