Recent, reliable screening tests for self-heating conducted in
accordance with UN method N.4 have demonstrated that both the solid salt
form of ferrous sulphate and the solid salt form of ferric sulphate give
a negative result. These salts are non-self-ignitable (at 140 °C using
the modified Bowes-Cameron cage test), which is as expected for these
non-combustible inorganic substances (Baltussen, 2010 studies 492704 and
494202). This conclusion applies for all members of the soluble iron
salt category as both a ferric and ferrous salt representative served as
