Oxygen acetylene use safety precautions to keep in mind the hearts of production safety
An oxygen and acetylene bottles bottle of fire closer than 10 meters, while the distance between the cylinders to keep five meters or more. Oxygen bottles with flammable gas cylinders is prohibited, wires and electrical equipment, protection of the zero line, zero line of work, such as mixed together, not near a heat source.
Second, check the pressure before use acetylene gas bottle, as well as valves, gauges, flashback arrestors, etc. are sensitive and reliable; When turned on, the operator should stand behind the side port of action to light, slow, prohibit fast opening valve.
Third, avoid transportation, storage and use of cylinders intense vibration and impact shock, cylinder safety accessories complete, color-coded compliance.
Four, oxygen, acetylene bottles in transit prohibited the use of electric cranes, forklifts and other equipment lifting and transportation, during transport must be removed on the regulator, oxygen, acetylene bottles, with a non-leaking gas. Do oxygen bottles and bottles of flammable acetylene cylinders mixed transport.
Fifth, when you open the bottle valve, the force should be smooth, the operator should be located in the outlet side of the case by the gas shocks, should be used to check the cylinder pressure reducer wire port is intact, tight, to prevent high-pressure flush.
Six, is strictly prohibited bottle gas exhausted to remain more than air pressure to prevent intrusion and for inspection.
Seven, must be connected with the required gas cylinders, non-random access hose, to prevent accidents, and oxygen, acetylene hose length of 20-30 meters is appropriate. Are not allowed to used the short or long hose. Applications designed clip joints or annealed metal Szymborska tightly fastened. Hose fitting from the inside of the torch allowed to have 1.5m. Oxygen hose red, green acetylene hose not connected to the welding torch when the disorder.
Eight, when Hange found suck tempering or found sounds, immediately turn off the valve has acetylene torch on, and then close the oxygen valve, open the oxygen valve to pause after the welding dust blown off, resume normal use.
Nine, an explosion in the gas hose or regulator, should be burning off cylinder valve immediately.
Ten, if found Pingfa easy to burn plug or other parts of the bottle there should leak immediately stop operation, the cylinders transferred to a safe place to properly handle and not near a fire source.
XI, the application is easy to burn when the cylinder valve plug or other parts of the leak and fire due to the dry powder, carbon dioxide fire extinguisher, while cooling water to prevent further occurrence of dangerous sidewall.
Twelve, if found abnormal temperature rises sidewall, should immediately stop using, and with plenty of cold water spray to prevent combustion and explosion.
When thirteen, winter oxygen bottle head, reducers or piping from freezing, except for using less than 40 ℃ hot water to thaw, or the use of non-fire baked goods hit iron a class, nor fierce twist decompression table The adjusting screw to prevent the impact of large amounts of oxygen, causing the accident. When acetylene cylinder valves freeze, non-fire grill, if necessary, you can use warm water below 40 ℃ slow thaw.
Fourteen, oxygen, acetylene welding and cutting operations personnel must obtain special operations Welding work permit, so that certificates.
Fifteen, when using oxygen, acetylene equipment properly selected according to the thickness of the steel cutting tools, cutting materials should elevate the material is about 10mm, the following materials to prevent iron cut rotten.
Sixteen, at the end of use, shall cylinder valve closed, closed with good gas and cylinders back into a predetermined position, finishing a good oxygen equipment, wear a good bottle caps, and clean use of premises clean.
