SAFE HANDLING OF COMPRESSED GASES

Observe the following special rules when working with acetylene cylinders:

  1. Always store acetylene cylinders upright. They are partially filled with liquid acetone, which can be discharged instead of or along with acetylene.

  2. Do not use an acetylene cylinder that has been stored or handled in a non-upright position until it has remained in an upright position for at lease 30 minutes.

  3. Ensure that the outlet line of an acetylene cylinder is protected with a flash arrester.

  4. Never exceed the pressure limit indicated by the warning red band of an acetylene pressure gauge.

  5. Use the correct kind of tubing to transport the gaseous acetylene. Some tubing materials such as copper form explosive acetylides.
