Gas piping with NFPA

[petemd]

Is around a gas pipeline (natural gas) a hazardous area according NFPA and to what distances is it located. I heard there could be something in the NFPA 497A? Is it correct?
Furthermore is this hazardous area just located around flanges etc. or around the complete pipe?

Thanks in advance

Not sure about NFPA, but IP 15 would detail a hazardous area, depending on the pressure within the pipe. Hazardous areas only tend to runs from a leak source, not the whole pipe.

The installation of natural gas piping and most gas equipment does not automatically trigger any requirement for classification of an area as hazardous.

Probably half the houses in the US have gas water heaters, furnaces, and stoves. Just about 0% of those gas installations are treated as hazardous.

I am remodeling my old house and have install an underground tank (LPG) with gas piping in the walls of the house to service the stove, drier, fireplace, barbeque grill, etc. Now the electrician and the plumber say they "think" the gas pipes must be at least 3 ft away from any of their installation and want me to move the gas lines.

Anyone know of where NFPA-58 or elsewhere that this subject would be addressed?

Thanks for your help,
