Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Key value for chemical safety assessment

non flammable

Additional information

Flammability of solids

Testing of flammability is not considered to be required for inorganic metal salts in which (i) the cation is in its highest possible oxidation state (e.g. Ba2+) and which therefore is incapable of further reaction with oxygen, and (ii) the anionic component is similarly not capable of further reaction with oxygen. Barium dichloride can thus be designated as non-flammable. (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.

Flammability in contact with water

Testing of flammability in contact with water is not considered to be required, because barium dichloride does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable (cf. Annex XI of regulation (EC) 1907/2006). Furthermore, long-term industrial experience in practical handling of barium dichloride shows that it does not react with water.

Pyrophoric properties

Testing for pyrophoric properties of solids is not considered to be required, since barium dichloride is stable at ambient temperature (cf. Annex XI of regulation (EC) 1907/2006). Barium dichloride also does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (circa 20°C). Furthermore, long-term industrial experience in handling shows that barium dichloride does not ignite in contact with air.

Justification for classification or non-classification

Barium dichloride does not need to be classified for flammability according to Directive 67/548 EEC and CLP Regulation (EC) No 1272/2008 based on chemical structure and lack of functional groups.
