Additional information
Justification for classification or non-classification
Chlorine is classified as compressed gas according to GHS and has to be labeled with 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.
