Ruth Ann:
You want drains for safety and water management – and to prevent flooding the floor below the eyewash. Also install non-skid on the floor around the shower/eyewash because wet waxed floors are slippery. The amount of contamination that will be washed off in a L/min (eyewash) or gal/min (shower) will quickly dilute potential environmental concern by the time it reaches the connection to the POTW.

Subject: [DCHAS-L] Lab eyewash/safety shower drains
Good Afternoon,
Once again the following concern has arisen: lab eyewash/safety shower units cannot drain with regular water due to possible contamination of the environment, e.g., if someone were washing off a sulfuric acid spill. Can someone provide a reference that this is (or is not) okay?
Thanks!
