Chlorine

[Yukon Jake]

We are working on a Building and installing a new pool system. This Chlorine room has EYSs and a lot of work that was done after the fact by Maintenace I'm sure.

Where does chlorine fall under in the NEC code, (Hazardous Locations)? In the SDS it says it May cause or intensify fire; oxidizer.

In the forms and concentrations that you're dealing with for a pool, it is unlikely that you have a hazardous location as far as the NEC is concerned. The NEC is more concerned with the presence of fuel, and not oxidizers, medical gases excepted.

I would check 680.12 including the Informational Note

There's 680.14 in 2020, which directs to 680.2:Corrosive Environment, which to me would clearly include any "chlorine room". 680.14 requires wiring methods to be listed for such use, which includes explicitly RMC, IMC, and rigid PVC, and RTSC
