It is also good to have water around in case your plumbing torchwork lights a FIRE.

About 10 years ago my father was working on a pipe at my house, he set the torch down to work on the fitting and when he looked back a dresser was on fire! He put the fire out with some wet towels he had been using to soak up the water from the pipe.

A fire extinguisher at hand is a good idea.
