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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 266-005-7 | CAS number: 65996-72-7 The dust generated during the charging, operation, and tapping of a steelmaking furnace and from steel conditioning, including that which is recovered through the use of pollution abatement equipment. Composed primarily of iron oxides. May contain varying amounts of other metallic oxides and trace compounds.

Description of key information
Study scientifically unjustified: According to Section 9.2.1.3, Annex IX of REACH, a simulation test on the degradation of Dust, steelmaking in soil is required. However, such a study is not applicable to this material for the following reasons: Since Dust, steelmaking is an inorganic substance, it does not undergo biodegradation i.e. microbial degradation to carbon dioxide and water, since it does not contain any carbon or hydrogen atoms in its chemical formula. This material will be degraded in environment by means other then biodegradation. Therefore, the simulation test on the degradation of Dust, steelmaking in soil is scientifically unjustified.
Key value for chemical safety assessment
Additional information
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.
