1.cylinders should be stored in a cool, dry, away from heat sources (such as sunshine, heating, fire), flammable gas cylinders must be separated from oxygen cylinders.
2.must not make oil or other flammable organic matter in the gas bottle (especially valve nozzle and pressure valve), also should not use cotton, hemp and other materials plugging, in case of combustion caused accidents.
3.use of gas in cylinders, to use a pressure valve (barometer), a variety of gas pressure gauges should not be mixed, in case of explosion.
4.not to use the gas in the cylinder all out, must retain the residual pressure above 0.05MPa (pressure relief valve gauge), flammable gases such as C2H2 should be residual 0.2~0.3MPa.
5.in order to avoid all kinds of gas bottles confused with the wrong gas, usually outside the gas bottle to a specific color to distinguish, and in the bottle to specify the name of the gas in the bottle.
