The previous publication of Doc 123 Code of Practice Acetylene had become very large. During its review, it will be split in separate publications on different topics. One of the topics is solvents for acetylene.
Acetylene is a chemically unstable gas which can decompose violently under pressure. The acetylene gas is dissolved into a liquid solvent within the cylinder to improve the acetylene’s chemical stability. This reduces the hazards involved in filling, transport and use.
This publication explains the safe use of solvents with acetylene. It describes the properties of the two solvents used for acetylene filling, acetone and dimethylformamide (DMF). It highlights the properties and the precautions to be taken when working with them.
It is intended for all personnel involved in the handling of acetone or DMF.
