Acetylene is a highly flammable gaseous hydrocarbon. It is colourless, unstable and highly combustible with a strong garlic odour. Used in welding and the manufacture of chemicals, this gas produces a very hot flame (over 3000°C or 5400°F) when combined with oxygen.
It is a very unstable compound and decomposes with ignition within a wide range of pressures and temperatures, for this reason acetylene is shipped as a stabilized solution under pressure and dissolved in acetone.
- Heating may cause an explosion.
- Explosive with or without contact with air.
- Extremely flammable.
- Do not discharge the acetylene cylinder at pressures above 15 psig (103kpa).
- Do not empty the cylinder below 5 psig.
- Recommended for atomic absorption.
- Keep container in well ventilated place.
- Keep away from source of ignition.
- Take precautionary measures against static discharges.
