Composition / Information on Ingredients
Chemical components, concentration ranges, and hazardous substance identification
Concentration is nominal. For the exact product composition, please refer to technical specifications. 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.
| Chemical Name | CAS Number | Concentration | Hazardous |
|---|---|---|---|
| Acetylene EC: 200-816-9 | 74-86-2 | 100% | Yes |
Notes
Refer to section 16 for full text of each relevant hazard statement (H). Dimethylformamide is listed in Annex XVII of REACH, and is subject to restrictions on its use. The applicable information from the exposure scenarios for this product are contained in the main body of the SDS.

Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Provide natural or explosion-proof ventilation that is adequate to ensure flammable gas does not reach its lower explosive limit.
Wear work gloves when handling gas containers. Standard EN 388 - Protective gloves against mechanical risk.
Safety glasses recommended when handling cylinders. Standard EN 166 - Personal eye-protection.
High concentrations that can cause rapid suffocation are within the flammable range and should not be entered.
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. Safety shoes are recommended when handling cylinders. Standard EN ISO 20345 - Personal protective equipment - Safety footwear.
If applicable, refer to the extended section of the SDS for further information on CSA.
