(OP)
My contractor has installing rigid conduit from receptacle to receptacle and the conduit goes under the slab and stubs up to each receptacle. However, he has not put explosion proof fittings on the conduit. Doesn't the NEC require explosion proof fittings everytime he leaves the room?

This is an unqualified opinion only as I do some design work on IS device internal circuits, but not the actual installations.

Room is used for battery storage
Batteries are lithium
NEC calls out for CL 1 for a foot above batteries in CHARGING areas.
Lead acid batteries emit hydrogen under charge - I do not believe you need to worry unless they are being charged.
These are lithium. I am not familiar with their charge characteristics.
You are only storing them not charging - do you really need Cl 1??
