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) :-) Sammye Betsy Shelton wrote: > I am currently involved in construction of two new laboratories and > was instructed by the city commercial building review department to > include a 1" high curb around the shower area to keep hazmat from > entering the floor drain in the event of a spill.
