I was a voting member for the Revision Committee of the appropriate ANSI St andard: ANSI/ISEA Z358.1-2009, American National Standard for Emergency Eyewash and Shower Equipment.
I did raise the issue about drains and run-off water and potential structur al damage to buildings, based on comments in the D-CHAS listserve.  ; The Revision Committee's almost unanimous consensus (I was "Doub ting Thomas") was that the issue of floor drains and run-off water was outs ide the scope of this standard (which indeed is a performance standard for the emergency equipment and therefore cannot supercede any building/ plumbing codes or Federal/State/Local standards/regulations regardin g run-off water).
For plumbed safety showers, the Standard states that the provision of Flu shing Fluid, most often potable water, should be capable of delivering 75.7 liters per minute (20 gallons per minute) for a minimum of 15 minutes. That would be about 300 gallons if I can still hit the right keys on my calculator. And there are some regulatory issues about whethe r such run-off water is considered hazardous waste, which greatly vary with state/local jusidictions as well. Also, without proper drains or special drains to a hazardous waste disposal holding tank, clea rly this run-off water will soak through floors and walls to lower floors i n the involved building. If nothing else, there remains the issue of water-damaged dry wall and other materials and mold/yeast overgrowth.&n bsp;

&g t; You know the story...new science building, lots of code-meeting safe ty showers, and of course there are no floor drains....
> ; I can buy spill berms...but does anyone have any other/better responses to what to do when the shower is actually used (not just testing, we've got a device for that). My understanding is a huge amount of water gushes o ut, for 15-20 minutes, and I'm assuming the potential for leaks in the floor below is another issue that needs to be dealt with. Luckily, in my time here we've only had one occasion when the shower was needed, and tha t was in our 'old' building, but--I'd rather plan ahead. What DO you do w ith the water while you're waiting for the hazmat response/cleanup team to arrive?
> So if anyone has a recommendation or a "this i s what happened to us" story that I could learn from...
