Two reasons, both related, affect the designs.  Environmental designs and
safety discourage waste water draining off easily into sewers.  Thus the
drains, if present, are at the high point in a lab.  Where there are special
concerns, no drain is included so that all water is contained and can be
disposed of appropriately.  This is a particular concern where significant
amounts of solvents or chemicals of concern are in use.  Also in places like
here in the San Francisco Bay Area where the sewers drain to the bay.

It makes for a mess of amazing proportions, but has a good reason.

Jenny, 

Weren't any laboratory personnel involved in the design process? What
about safety?

The ANSI standard, Z358.1-1998, Emergency Eyewash and Shower Equipment
doesn't appear to state the shower should be drained. The appendix,
under waste disposal, states 'consideration should be given to the
proper disposal of waste flushing fluids...'.

FWIW, when our lab was built in '92, the showers were placed above or in
close proximity to floor drains. Unfortunately, the locations chosen to
become floor drains happened to be local high spots in the floor...

Hi,

Our laboratory is going under renovation, and the contractor just
installed some eyewash/safety shower.  However, they are not connected
to any draining or plumping system in the building.  The engineers
stated that it's not required by any feds or state regulation to connect
the eyewash/shower to the drain.  

Does any one know if there is a regulation?

Any comments are appreciated.

Jenny

I concur-chemical splash goggles. That is my recommendation as a  Safety
