Common sense of safe use of oxygen!
Author：
1. The oxygen in the oxygen cylinder cannot be used up completely, and a residual pressure of 0.1Mpa must be left to prevent the explosion caused by acetylene backflow.
2. It is prohibited to use hands and tools contaminated with oil to operate the cylinder to prevent explosion.
3. The oxygen cylinder shall not be strongly impacted. It is prohibited to load, unload or carry by throwing, throwing or other methods that are easy to cause impact, and it is prohibited to lift by crane.
4. When opening the bottle valve and pressure reducer, people should stand at the side; The opening speed shall be slow to prevent burning caused by high temperature of organic material parts or rapid gas flow, which may produce electrostatic sparks.
5. In winter, when the pressure reducer and pipe system of the gas cylinder are frozen, it is strictly forbidden to bake the gas cylinder with fire or strike the gas cylinder with iron tools or the like, and it is not allowed to tighten the adjusting screw of the pressure reducer to prevent accidents caused by sudden large amount of oxygen rushing out.
6. It is prohibited to use oxygen cylinders without pressure reducers.
7. The oxygen cylinder shall not be close to the heat source, electrical equipment, grease and other inflammables.
8. The distance between gas cylinder and open fire shall not be less than 10m. The distance between oxygen cylinder and acetylene cylinder is greater than 5m.
9. The oxygen cylinder and acetylene cylinder shall be placed in a fixed position and marked with a yellow line of 50mm.
