Acetylene is the most common gas used for fueling cutting torches; when mixed with pure oxygen in a cutting torch assembly, an acetylene flame can theoretically reach more than 5,700 degrees F. If you use acetylene for cutting, you probably know about the fire hazards associated with the flame and hot slag. Acetylene is also sensitive to excessive pressure and temperature, static electricity, and mechanical shock.

Acetylene can decompose violently under pressure in excess of 15 pounds per square inch. Always store acetylene cylinders in a well-ventilated area away from oxidizers, open flames, sparks, and other sources of heat or ignition. Storage areas must have fire extinguishers or fire suppression equipment.
