Remarks on result:

other: Based on its structural properties test substance is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Classification

The test item test substance is an organic compound which contains oxygen and fluorine. Therefore the second criterion of the Orange Book has to be applied. Fluorine is bonded to carbon only whereas a part of the oxygen atoms is also bonded to sulphur. In absence of other criteria this finding would lead to the recommendation for experimental testing. Further evaluation has been done by detailing the molecule in small subunits for which a classification with regard to oxidizing properties already exists. The subunits is sodium benzenesulfonate, which is not classified to be oxidizing. Additionally, it can be stated that the oxygen balance of test substance is negative as calculated based on the UN Recommendations on the Transport of Dangerous Goods. In principle this means, that there is a surplus of carbon atoms for a complete reaction according to the following reaction scheme:

CxHyOz + [x + (y/4) – (z/2)] · O2 → x · CO2 + (y/2) · H2O where CxHyOz is the test item.

Interpretation of results:

GHS criteria not met

Conclusions:

Based on its structural properties test substance is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Executive summary:

The purpose of this study was to estimate the oxidizing properties of test substance based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Fourth revised edition, 2003, Appendix 6, “Orange Book”) where a set of criteria is compiled to evaluate the need for classification of materials as oxidizing substances. Applying the internationally recognized UN Recommendation criteria and further criteria as published in several official documents, test substance is found to be non-oxidizing and therefore is not to be tested experimentally for the classification under division 5.1 as oxidizing substances. Thus, it can be concluded beyond a reasonable doubt that test substance is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Description of key information

The substance is considered as non-oxidising.

Key value for chemical safety assessment

Justification for classification or non-classification

On the basis of criteria for oxidising properties given in the UN Recommendations on the Transport of Dangerous Goods and further criteria published in other official documents, FAT 40851/A TE is considered as non oxidising. A classification for oxidising properties according to Regulation (EC) No. 1272/2008, hence is not required.
