- Justification for type of information:
- The conduct of experimental verification for flammability is not considered to be scientifically justified.
The conduct of testing pyrophoric properties is not considered to be required, since in several decades of production, marketing and downstream use, none of the lead compounds have ever been reported to exhibit such properties. Furthermore, comparison of the substance to know pyrophoric substances suggests that the substance does not have structural alerts for pyrophoricity. 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 basic lead carbonate, which is the main component of this substance.
Testing of flammability in contact with water is not considered to be required, because the substance does not contain components or groups that might lead to a reaction with water or damp air, further 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 gases.
Since basic lead carbonate represents an inorganic salt containing lead in an oxidised status (2+) and an anion of an inorganic acid which is not susceptible to any form of oxidation, the substance is thus intrinsically less combustible than lead itself, and a test conducted according to the same method cannot reasonably be expected to yield any other results. Testing of flammability was recently also
conducted for lead metal powder, yielding a result of “not flammable”. In addition to the above mentioned statements, based on the registrant’s long term industrial experience of handling of the substance, it is not pyrophoric, is not flammable in contact with water, and is not flammable on contact with a hot flame. In conclusion, the conduct of further experimental verification for flammability is not considered to be scientifically justified. - Conclusions:
- non flammable
not pyrophoric
