Hi,
Some jurisdictions prohibit drains at safety showers because a chemical spill in the lab would be directly released to the sewer. The prohibition doesn’t derive from concerns about wastewater generated from personnel decontamination.

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!
