Natural Gas Regulator Building

In the design of structures, one of the very first things to do
is to assign an Occupancy Group designation, "then" [ and
ONLY then ] the determination of the various systems that
are to be installed in \ on that structure are clarified.

In **nitramnaed**' application, he has already determined that
the structure should have Class I electrical components.

To me, this is "putting the cart before the horse" [ so-to-speak ].
NOTE: No disrespect to **nitramnaed** is inferred
or intended.

IMO, ...the structure either should have an H Occ. Group
assignment, or the Class I electrical components are not
required.

Thoughts ?

There are places where there is hazardous electrical

But those places are not always H Occupancy category

Agreed **cda** !.......Can you please provide an example,
or examples of some that are enclosed, ...similar to
**nitramnaed** application ?

Thanks !

Repair garages, wood shops, gas stations, spray booths....

Thank you to early in the morning.

This would not be covered in out State as well

The questions is if the improved electrical equipment is being installed because it is code required. If the designer and owner choose to install improved systems above and beyond what the code requires, it should not drive what occupancy the building is.

Much Thanks for the input of other examples......I hope that
we haven't discouraged **nitramnaed** to stop participating
in this discussion.

Shall we say that the consensus is for the structure to
[ possibly ] be classified as a U Occ. Group, with Class I electrical
components ?

FWIW, I am still having a difficult time with the comment of "You
don't want a spark in case of a leak".......Somehow that just
doesn't seem kosher.

What say ye ?

Inspected and did plan reviews for large pumping stations for fracked natural gas in PA. These are not for utility companies. The building are "U" and just the area immediately around the pumps is H. But all the electrical equipment was sealed everywhere in the building.

Sorry,
I was on Holiday for 2 weeks so I'm just catching up on this lively discussion.
I design a lot of water and wastewater plants and we have class 1 electrical required all the time. I most cases it's because the chemicals in use are below the required limits for an "H".
With that being said, i don't believe class 1 automatically indicates an "H" occupancy.
I'll retract the statement "have a spark in case of a leak" as it is to simple of a statement on the purpose of the class 1 electrical requirement in the NEC.
I am intrigued by "ICE" statement that this may "Exempt from Permit". I will explore this. But if successful in this argument, I will lose the work.

To update. The city accepted the Utility (U) occupancy for the regulator enclosure.
