Additional information
1,1,1,2-tetrafluoroethane (HFC 134a) is a colourless, odourless gas at standard temperature and pressure. It is supplied as a liquefied gas under pressure and is therefore classified under EU Classification, Labelling and Packaging of Substances and Mixtures, (CLP) Regulation (EC) No. 1272/2008 in Hazard Class 2.5: gas under pressure, with the hazard statement H280: "Contains gas under pressure; may explode if heated."

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
