Gas line - move?

Once you shut off the main at the meter, open the line there is no danger. Even if there is a leak while working on the line, and you are able to stop it, there is no danger. It takes a high amount of vapor in an area that would cause a danger, if there is a spark.

yes, i know that it is a vapor.


what i didn't know is that there isn't enough in the line to make it a problem.

thanx

No, there is nothing in the line to be a problem. Only with fuel oil would there be something in the line that can cause a problem.

Gas line - move?


This subject of no non licensed people even thinking of touching a gas line is really puzzling to me. Possibly so because from an early age I've never ever considered paying to have gas line work done. In later years I've retired from natural gas compression from the time it came from the dirt deep down mixed with water, propane and all those other unwanted tanes ranging from nearly a vacuum to 1,200 lbs. pressure on lines from 1/4" to 12 inches. Screwed fittings, flanged fittings AND yes the ever so dangerous and absolutely no good compression fittings that a good number of licensed professionals don't have a clue how to correctly connect.

But it seems to be just fine for the non licensed home owner DIY- er to monkey around with electrical they know very little about.

Have you ever smelled electricity when it was becoming dangerous and about to instantly kill you on the spot or to you and your family's well being and about to cause your house to burn? I doubt it. It doesn't yet have mercaptan to warn us.

Natural gas has a upper and lower combustible limit it must be within to even burn. The average is 5 to 15 percent fuel ratio to air for NG and Propane is 2.1 to 10.1 percent. Have you ever seen electric cut you that much slack? I doubt that one too.

Keep minimum code in mind for safety;

"G2415.3 (404.3) Piping in concealed locations. Portions of a piping system installed in concealed locations shall not have unions, tubing fittings, right and left couplings, bushings, compression couplings, and swing joints made by combinations of fittings.

Exceptions:

1. Tubing joined by brazing. 2. Fittings listed for use in concealed locations" From; http://publicecodes.cyberregs.com/icod/irc/2009/icod_irc_2009_24_sec015.htm

Fairview, as long as a person uses common sense when working with the piping, it it no different than running potable water lines.

The dangers lie, when people ignore the smell or a leak and sign it off to a nothing.

I have been around this stuff all my life, due to my grandpa owned a major construction company here in Illinois, grew up watching my father do electrical, plumbing and gas piping.

It is not Rocket Science and entailing that there is a great fear if you even touch a gas line or fittining will blow you up, is just telling people that they are ignorant and you are the only one that is God and should be the only to do this stuff.

I can tell you this, more accidents and headaches are caused by those in the trades trying to hirry up and get the job done, or creating a band-aid, thane taking their te to do the job right.

And when does the before mentioned happen, in the homes or on the peoperty of those in the trades.
