Assessed regarding its chemical nature
Testing for this endpoint has been waived as an experiment is considered
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.22.214.171.124, 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 a negative
experimental result, evidencing that these salts are non-flammable, as
expected for these non-combustible inorganic substances. This conclusion
applies consequently as well 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

2001/59/EC (28th ATP of Council Directive 67/548/EEC), and CLP (5th ATP
