Acetylene Gas Cylinder refers to a special pressure vessel filled with filler for storing and transporting acetylene. The appearance is similar to the oxygen cylinder, the surface is painted white, and the words "acetylene" are written in red paint. The acetylene Gas Cylinder is equipped with porous filler immersed in acetone, so that the acetylene can be safely stored in the bottle. When in use, the acetylene dissolved in acetone becomes gas and separated out, while the acetone remains in the bottle so that it can be filled with acetylene again.

Acetylene is a flammable and explosive substance, so the explosion-proof nature of acetylene gas cylinders should pay attention to:
1. Acetylene gas cylinders should be supplemented with acetone according to relevant regulations, and should not be excessive;
2. Determine the acetylene filling volume according to the acetone volume, strictly control the filling speed, and prohibit excessive filling;
3. Use qualified acetylene gas cylinders.
Pay attention to:
1. The place where the acetylene bottle is placed shall not be close to heat sources and electrical equipment, and the distance from the open flame shall not be less than 10m;
2. Use upright;
3. It is strictly forbidden to place it in places with poor ventilation or radioactive ray sources;
4. It is strictly forbidden to knock, collide, arc off the bottle or place it on the insulator;
5. Exposure to the sun is strictly prohibited, and it is strictly forbidden to heat the bottle with a heat source above 40 degrees Celsius;
6. The acetylene cylinder and the oxygen cylinder are placed on the same trolley and separated by non-combustible materials;
7. Equipped with special pressure reducer and flashback preventer; it is strictly forbidden to open and close acetylene gas cylinders with ignited welding and cutting tools;
8. If the acetylene bottle leaks during use, deal with it in time;
9. Leave a residual pressure of 0.05MPa.
The safe distance between the acetylene cylinder and the oxygen cylinder is 5 meters, and neither can be exposed to the sun.
Acetylene leakage treatment method: dilution and dissolution with sprayed water. Build a dike or dig a pit to contain the large amount of waste water produced. If possible, send the leaked air to an open place with an exhaust fan or install an appropriate nozzle to burn it. Leaking containers should be properly handled and used after repair and inspection.
