Grounding a fire cabinet

[Kevin1967]

I walk through the facility that I work in and I notice a lot of ground cables leading from the flammable supply cabinets to a metal rail that is bolted to the concrete.

Or

The grounding cable is run to a bolt that is is coming from the concrete to the handrails foot that is bolted to the ground.

Is that cabinet grounded?

Thanks in advance for your help.

If these are supply cabinets, why is grounding needed at all? Is there power to something within or attached to the cabinets. If for example each cabinet has a light inside, then the EGC supplied with the circuit that feeds the lights is all you need.

IIRC, flammable liquid storage cabinets are required to be grounded.

OK, thanks. Not ever having dealt with the IIRC, I would not know what it means when it uses the word, "grounded." I suppose that is the OP's intended question.

Grounded to prevent the buildup of static charges. I would say that those methods are appropriate without some standard or code to say otherwise.

Is that grounded or bonded??

Grounded.

Fire Code
5003.9.5 Static Accumulation
Where processes or conditions exist where a flammable mixture could be ignited by static electricity, means shall be provided to prevent the accumulation of a static charge.

Question I have is, if the Fire Marshal says you have ground the storage cabinet, is it then subject to NEC for directions on how to ground it?

First I would not consider a storage cabinet without transfer of product to be covered by the section you cited.
Second, the NEC does not have rules for that type of grounding. You might look to NFPA 77, Recommended Practice on Static Electricity.
