Turn off the oxy first, then the fuel.


No!

Fuel gas on first AND off first to avoid the explosions. I was
taught
that the only time you should turn the oxygen off first is if you've
had a blow back and the flame is burning in the torch - or horror of
horrors in the pipe.


I'll second that, and always leave the cylinder valve key in the
oxygen valve - oxygen being the far more volatile and dangerous gas.

Also, unlike someone I know (who should have known better...), install
any flash-back arrestors at the gauge end of the hoses and not the
torch end... :~(
