Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Determination of explosiveness is not relevant. The substance is a solid, inorganic, mineral material and it is in oxidized form and thus cannot burn. In fact the substance can be used at elevated temperatures as a component of refractory mass to protect from heat and flames. Ferrochromium slag products are put on a market and used as gravels and granules in particle sizes, which cannot form an explosive mixture with air. According to mineralogical studies metals in ferrochromium slag are mostly in oxidised form and free metal is encapsulated in spinels, so there is no possibility of metal dust explosion.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
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.
