Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Highly flammable solid (A10): the substance is not highly flammable
In contact with water substance liberates highly flammable gases (A12): the substance does not liberates highly flammable gases in contact with water (derogation)
Pyrophoric substance (A13): the substance does not liberates highly flammable gases in contact with air (derogation)

Key value for chemical safety assessment

Additional information

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. This substance can thus be designated as non-flammable. (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.10.3).

Testing of flammability in contact with water is not considered to be required, because the substance 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. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases (in accordance with section 1 of REACH Annex XI).

Testing for pyrophoric properties of solids is not considered to be required, since this substance is stable at ambient temperature. This substance 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 the substance does not ignite in contact with air (in accordance with section 1 of REACH Annex XI).
