Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is incapable of reacting exothermically with combustible materials

Justification for type of information:

Structural assessment concludes no oxidising potential caused by any of the chemical groups or species present.
Typical oxidising agents include halide-oxygen groups (eg chlorates), nitrogen-oxygen groups (eg nitrates) and some metal-oxygen complexes. None of these groups are present in the substance.
It is concluded that the substance does not have a sufficient oxidising potential for classification as an oxidising agent and is not hazardous in this respect. It is considered that testing is not required.

Interpretation of results:

other: Chemical composition does not precluse oxidising potential

Conclusions:

The material has been heated in air to attempt drying and appears to decompose with loss of the nitrate to NOx. There was no evidence of violent exotherm or combustion. Inorganic salts are not typicallly considered likely to auto-ignite on heating.
The presence of nitrate does not exclude the possiblity that the substance does have oxidising properties, but in the form supplied, will not be classified as dangerously oxidising.
