Stefanie,
That is what I have understood as well. You can disinfect a drain from Biological stuff and you can make a drain large enough to handle the flow, but how do you prevent a hazardous
chemical from entering the water system? You can't. ergo - no drain.

Hi,
I thought the main reason to not have a drain under the safety shower is that you don't want whatever you are trying to wash off to go into the general waste water system. Did I have it wrong all these years?

Hi Everyone,
This is a topic that's been discussed in depth before, but the architects planning our new science building had two arguments against drains under safety showers that I wasn't that familiar with and wanted to get people's thoughts:
1) Some medical facilities are calling them a health hazard due to possible build-up of biological stuff (presumably bacteria or mold?)
2) The drain will be too small to capture enough water to make it worth the cost (they did accept that a sloped floor might help with this)
