haz location

What would you consider an outdoor area that recieves natural gas at high pressure and regulates it down for low pressure distribution. This is outdoors,and has a fence around it. Would this fall under Class I Div II? There is normally not gas present in the air.

paul,
article 500.5 b (1) 3 considers this a class one-division one area. not normally present is one thing --- but if it "could be" present is mentioned. and i'm assuming every once in a while it is present....

Just out of curiousity - the section you cite would seem to imply the area around any gas meter should be classified. there are a lot of gas meters out there, including at my house. i don't recall my side yard is classified.

Sorry Charlie, but I also think this is a non-classified area. If it were classified, we would have to classify the area around every natural gas pipe. That would include my entire house.

Also, I don't see how a leak would also cause a simultaneous electrical source of ignition that 500.5 b talks about.

By the way, something that:

recieves natural gas at high pressure and regulates it down for low pressure distribution.

probably includes every residential gas meter.

I'm moving this to the new "Hazardous (Classified) Locations" topic area.
