Demo of Natural Gas Line

I'm pulling out a 1 1/2" galvanized natural gas pipe that fed an outdoor pool heater. There are no unions in the portion above ground, so it looks like I'm going to have to cut the pipe. I've disconnected both ends and left them open for a couple of days, but I'm worried about residual gas in the line (which is easily 125' long). Should I be worried about cutting into the center of the line with a reciprocating saw?:eek:

You can take your shop vac and put it on blow and just blow air through it for a few minutes, then wait 1/2 hour for any expelled gas to dissipate, then cut away.

If the end you're blowing to is inside, then blow the other way, so the gas is expelled to the outside.

Whatever you do, don't suck the gas into the vac, you might blow yourself up.
