keep the gas compound clear of all combustibles, leaves, paper, oil, grease and chemicals
-
do not store oxidising gases with flammable gases

when opening any cylinder valve or isolation valve do so slowly, be aware of the pressure reading and check any new connections for leaks - use soapy water
-
do not tape cylinder threads - it is the bull nose that seals not the thread

when opening any valve, open it fully then shut it down about half a turn - the next person can then tell if it is open or shut and it will not jam against its stop

-
take care of all cylinder nuts and bull noses, use correct spanners and avoid scratching the face of the bull nose
-
position the cylinder so the pig-tail does not twist or kink
-
set the pressure on a 2-stage regulator (manifold) 5-10 PSI higher than the required work pressure in the laboratory, then reduce it locally - this should allow for a slight pressure drop

with any problems ASK
