Description of key information
Based on the molecular structure and practical experience, iodine is not flammable when coming into contact with an ignition source, with water or with air.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
Flammability: Iodine is an inorganic substance that does react with oxygen to sustain a combustion thus is not expected to ignite along a test substance pile.
Therefore in accordance with Regulation (EC) No. 1272/2008 section 2.7.2, the substance should not be classified as flammable solids.
Substances / mixtures which in contact with water emit flammable gases: It does not ignite in contact with water or to the evolution of a flammable gas.
Therefore in accordance with Regulation (EC) No. 1272/2008 section 2.12.2.1, the substance should not be classified as substances or mixtures which in contact with water emit flammable gases.
Pyrophoric solids: Iodine does not ignite after 5 minutes of exposure to air.
Therefore in accordance with Regulation (EC) No. 1272/2008 table 2.10.1, the substance should not be classified as pyrophoric solids.
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.
