Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

MnCl2 has been determined not to have oxidising properties as the test material/cellulose mixtures failed to propagate combustion at a rate greater than or equal to that of the barium nitrate/cellulose mixtures.

Executive summary:

This was chosen as Key study as it is the only available study which is of relevance and of sufficient quality for classification and labelling and for risk assessment.

 

The study report includes the entire information requirement as appropriate for EU Method A.17 (Oxidising Properties (Solids)) guideline. Therefore the quality criteria of the study have been fulfilled as the study was conducted to guideline.

 

Lack of any observed effect in the study supports the lack of classification and labelling of this substance.
