2.3 Other hazards
For safety reasons, acetylene is dissolved in a solvent, either acetone (CAS No, 67-64-1) or N,N- dimethylformamide (DMF) (CAS No. 68-12-2). A small quantity of the solvent (as an impurity) may be carried over with the acetylene as it is used. The concentration of the solvent in the gas is below the limit which could affect the classification of the acetylene.
2.1 Classification of the substance or mixture
Classification according to Regulation (EC) No 1272/2008 Flammable gas (Category 1) : H220: Extremely flammable gas. Chemically unstable gases (Category A) : H230: May react explosively even in the absence of air. Gases under pressure (Dissolved gas) : H280: Contains gas under pressure; may explode if heated.
