Additional information

Justification for classification or non-classification

Lead tetroxide 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 lead tetroxide (“minium”) is considered to be “inert” in the context of explosivity, since it already represents lead in an elevated oxidation status. Finally, it is noted that despite the long-term use of lead tetroxide, this substance is not classified for explosive properties according to UN transport regulations. In conclusion, the conduct of further experimental verification is not considered to be required, and for the reasons stated above, derogation from testing is hereby applied for.
