Acetylene is used for autogenous welding and cutting of metals with an increased temperature routine.

Example of labeling for cylinders.

It is packaged in balloons with volumes of 40 liters and 10 liters. Acetylene gas in the balloons is dissolved in acetone, and for safety purposes, the balloon is filled with a porous mass. Depending on the type of mass, the maximum pressure in the balloon is 15-18 bar at a temperature of +15 °C.

Mixtures of acetylene with air or oxygen release large amounts of energy in the form of heat or explosion after ignition. The flammability limits in air at atmospheric pressure are between 1.5% and 82% by volume. Minimum energy is required for ignition, for example, a static spark can ignite a mixture of acetylene and oxygen.

All materials used, including non-metallic components such as valve caps, gaskets, and membranes, must be resistant to acetylene and its solvents. Acetylene piping should be made of steel. Details made of silver, copper, or an alloy containing more than 65% copper should not be used due to the risk of forming explosively hazardous connections between copper and acetylene.

When storing and using acetylene, it is necessary to ensure adequate ventilation and comply with the classification rules of electrical equipment. Open flames and smoking are strictly prohibited.
