Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Not classified according to test result for flammability (in contact with a flame, EU A.10 method).

Further, basic lead sulfite does not exhibit pyrophoric properties. In several decades of production, marketing and downstream use, none of the lead compounds have ever been reported to exhibit such properties. Furthermore, based upon a statement on the pyrophoric properties of the European Lead Stabiliser Association (ELSA, 2004), experimental handling over the last 50 years revealed no such properties for dibasic lead sulfite.

Basic lead sulfite does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has not reported formation of any gas or gases whatsoever in any of the lead compounds.
