That's the kind of regulation that gives safety a bad reputation.  I 
have never understood this argument - that showers and eyewashes cannot 
be plumbed because hazardous materials might get in the water system.  
Good grief, I put a larger amount of hazardous materials in my toilet 
when I clean it.

Not to mention that if am the one mopping it up - guess where I am going 
to ring the mop out? Yep, in the sink.  Maybe if it is an acid, we can 
dump some bicarb in the water while the person decontaminates. That way 
it will be neutralized and ok to dispose of down the drain (at least in 
my state) :-)
