【 Weak current College 】 gas welding (cutting) fire safety practice---Power By 【 China power house network 】

1. check the acetylene, oxygen cylinder, rubber hose fittings, valves and other possible leak location is good, there is no grease on the torch, welding (cutting) ju's shot suction capacity.
2, oxygen, acetylene cylinders should separately, the spacing of not less than 5 m. Job preparation of clean water, preferably point for timely cooling tip.
3, the hose should be used as pressure experiment of qualified products, you may not use substitutes, metamorphic, aging, embrittlement, leakage and oil-hose, tempering down burning should replace the rubber hose, combustible, combustion gas hose must not be mixed.
4. when the gas welding (cutting) occurred due to high temperature torch fried quail, must immediately close the acetylene gas valve, welding (cutting) ju put into the water cooling, but also oxygen valve should be closed.
5. welding (cutting) torch ignition application oxygen blowing before, check the wind pressure and plug, air leakage phenomenon.
6, for shooting the suction welding torch, torch ignition should encode micro-opening on oxygen valve, and then open the acetylene gas valve and flame ignition adjustment.
7. using acetylene cutting machine, you should first open the acetylene, hydrogen and oxygen; the use of open cutting machine, you should open after hydrogen and oxygen.
8, jobs. When acetylene in shedding, rupture, ignite, it should first be welding or cutting torch flame is off, and then stop the gas supply.
9, when the oxygen pipe fire, should be immediately shut down the oxygen cylinder valve to stop oxygen supply. Prohibition of the use of the method takes the bending.
10, entered the container welding and cutting off the ignition and should be outside the container.
11, flames, torch, first shut off valve, acetylene and oxygen valve; cutting torch first off oxygen valve, and then close the acetylene and oxygen valve.
12, when tempering, hose or tempering on fire prevention, should promptly closed welding comfort on oxygen valve and acetylene gas valve, and then close the level of oxygen and acetylene gas valve, and then take control measures.
13, rubber hose and high heat pipes and high volume, power cord, isolation, not weight.
14, trachea and electric welding power conductors shall not be used in the laying, wound together.
