Turn off the oxygen at the tank (Note: Oxygen tank valves should be opened FULLY when opened. There is a seal in the full open position to prevent leaks of the oxy due to the 2000PSI pressure in the oxy tank.) This applys to refillable oxy cylinders.
In the manual supplied by the gas company here (NZ)they advise
to turn the oxygen valve on 1 1/2 turns, they say the oxygen is
the more dangerous as this adds to a burning fuel and should be
turned off as quickly as possible. Acetylene will just burn with
a sooty flame the flash back valve stoping it going back into the
cylinder.This cylinder also has a lead safety valve in the base
the lead melting releasing the pressure in the cylinder should it
be subject to high tempretures.
Good one David.
David is correct in his format in closing down the gas plant.
