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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Testing for this endpoint has been waived as an experiment is considered scientifically unjustified.
In previous reviews (e.g. OECD 2007), statements such as “The substance does not contain elements such as carbon and hydrogen necessary for auto flammability/ flammability in air” have been made.
Flammability is not expected to be a significant hazard for the water soluble iron salts. However, the ECHA (2008, Section R.7.1.10.3, p 123) endpoint-specific guidance contains the statement “Care should be taken not to confuse the inability to support combustion with the inability to burn”. Data waiving can therefore not be applied straight forward across the set, but can be based on experimental data for a representative salts of the ferric and ferrous forms as long as the related anions are comparable with regard to flammability properties.
Reliable screening tests for flammability conducted in accordance with UN method N.1 have demonstrated that both a solid ferrous salt form (ferrous sulphate, Baltussen 2010, study 494202) and a solid ferric salt form (ferric sulphate, Baltussen 2010, study 492704) give negative experimental results, evidencing that these salts are non-flammable, as expected for these non-combustible inorganic substances. This conclusion applies consequently also to other water soluble ferric and ferrous chlorides as the chloride is deemed not different from sulphate with regard to its contribution to flammability of iron salts.
The likelihood of pyrophoric properties and flammability on contact with water can generally be negated on the basis of functional groups present, the handling experience and particularly for salts marketed as watery solutions.
Justification for classification or non-classification
The following statement bases on DSD, the Commission Directive 2001/59/EC (28th ATP of Council Directive 67/548/EEC), and CLP (5th ATP of Regulation (EC) No 1272/2008 of the European Parliament and of the Council) as implementation of UN-GHS in the EU:
Regarding the chemical nature of the submission item no flammability seems possible.
