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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 266-966-2 | CAS number: 67711-90-4 Solids recovered from exhaust gas streams found in furnaces, flues and settling chambers as a result of roasting, smelting and converting operations. Constituents found as end products are dependent upon the materials used during various operations.

Description of key information
UN Transport N1 cannot be waived in all cases. Flammability hazard could not be excluded in all cases based on expert judgement (characterization of the UVCB, IUCLID 4.23 & other physico chemical information) and experience in handling and use. Key study on representative worst case demonstrated that the substance is not readily combustible solid under Division 4.1 (UN N1)
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
UN N1 test performed on representative worst case flue dust demonstrated that the solid is not readily combustible under Division 4.1. Additional expert judgement based on chemistry and mineralogy of the flue dusts, as well as experience in handling and use confirm this result for all flue dusts (as defined under Section 1.2)
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.
