Composition Notes
The cylinder contains a porous material which in some cases contains asbestos fibres. The asbestos fibres are encapsulated in the solid porous material and are not released under normal conditions of use. See section 13 for the disposal of those cylinders. Dimethylformamide is on the Candidate List of Substances of Very High Concern (SVHC) that might be subject to authorization for future placing on the market and uses. For safety reasons, the acetylene is dissolved in acetone (Flam. Liq. 2, Eye Irrit. 2, STOT SE 3) or dimethylformamide (Flam.Liq.3, Repr. 1B, Acute Tox. 4, Eye Irrit. 2) in the gas receptacle. Vapour of the solvent is carried away as impurity when the acetylene is extracted from the gas receptacle. The concentration of the solvent vapour in the gas is lower than the concentration limits to change the classification of the acetylene.
Emergency First Aid Measures

Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
Provide adequate general and local exhaust ventilation. Systems under pressure should be regularily checked for leakages. Gas detectors should be used when flammable gases/vapours may be released. Consider the use of a work permit system e.g. for maintenance activities.
🧤 Hand Protection
Wear working gloves when handling gas containers. Standard EN 388 - Protective gloves against mechanical risk.
👁️ Eye Protection
Wear goggles with suitable filter lenses when use is cutting/welding. Wear safety glasses with side shields. Standard EN 166 - Personal eye-protection - specifications.
😷 Respiratory Protection
None necessary.
🦺 Skin/Body Protection
Consider the use of flame resistant anti-static safety clothing (Standard EN ISO 14116 - Limited flame spread materials, Standard EN ISO 1149-5 - Protective clothing: Electrostatic properties). Wear safety shoes while handling containers (Standard EN ISO 20345 - Personal protective equipment - Safety footwear).
🌍 Environmental Exposure Controls
Refer to local regulations for restriction of emissions to the atmosphere. See section 13 for specific methods for waste gas treatment.
