Additional information

Justification for classification or non-classification

Basic lead sulfate does not require classification for explosiveness.

The experimental determination of the explosivity of a compound is not required, if available thermodynamic data (reaction enthalpies) and/or the absence of certain reactive groups (Bretherick, 1990) in the structural formula indicate that the substance will not decompose violently under formation of gases or release of energy and thus does not pose a risk for explosivity.

The substance “basic lead sulfate” consists of lead cations and the sulphate anion which can all be considered as “inert” in the context of explosivity. Therefore, the substance “basic lead sulfate” may also considered to be void of any explosive properties. Furthermore, despite the long-term industrial handling, this substance is not classified for explosive properties according to UN transport regulations.

The study is therefore waived in accordance with REACH Annex VII, Section 7.11, Column 2.
