Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Auto-flammability: barium sulfide does not have self-heating properties
Key value for chemical safety assessment
Additional information
Self-ignition is not considered to be of relevance for this substance, since this would require heat to be developed either by reaction of this substance with oxygen or by exothermic decomposition and which is not lost rapidly enough to the surroundings (in accordance with section 1 of REACH Annex XI) . Since barium sulfide represents the highest oxidised form of barium it is intrinsically not combustible and can safely be assumed not to be ignitable under the conditions given in Test N4 Part III, sub-section 33.4.1.6 of the “UN Recommendations on the Transport of Dangerous Good, Manual of Tests and Criteria”. Furthermore, a screening test according to regulation (EC) 440/2008 shows that barium sulfide does not have self-heating properties in the sense of the guideline A.16.
In conclusion, the conduct of further experimental verification is not considered to be required.
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.
