According to the criteria as described in the UN Recommendations on the Transport of Dangerous Goods (Orange Book, 3rd edition, 1999):

- the classification procedure using experimental testing need not be applied for organic compounds if the compound does not contain oxygen, fluorine or chlorine.

Since TIC2782 (T002907) contains oxygen and chlorine, the second criterion of the Orange Book UN Recommendations has to be applied:

- the classification procedure using experimental testing need not to be applied for organic compounds if the compound contains oxygen, fluorine or chlorine AND these elements are chemically bonded only to carbon and hydrogen.

This second criterion is fulfilled for TIC2782 (T002907).

Additionally, it can be stated that the oxygen balance of TIC2782 (T002907) 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:
Applying the internationally recognised UN Recommendation criteria, TIC2782 (T002907) is found to be non-oxidising and therefore is not to be tested experimentally for the classification under division 5.1 as oxidising substances. Thus it can be concluded beyond a reasonable doubt that TIC2782 (T002907) is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Description of key information

The substance T002907 was concluded beyond a reasnoable doubt to be not capable of causing fire or enhancing the risk of fire when in contact with combustible material in a desktop assessment based on the UN Recommendations on the Transport of Dangerous Goods (Orange Book, 3rd edition, 1999) (Weissenfeld M, 2005).

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Justification for classification or non-classification

The classification procedure using experimental testing need not to be applied for organic compounds if the compound contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon and hydrogen. This criterion is fulfilled for T002907.

Additionally, the oxygen balance of T002907 is negative.

Thus the substance T002907 does not need to be classified as an oxidising substance according to the CLP regulation.
