GHS criteria not met

Conclusions:

Based on criteria defined in UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3rd edition, 1999), BLUE GS 5664.80 considered 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 BLUES GS 5664.80 is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Executive summary:

The oxidising properties of BLUES GS 5664.80 were screened based on the UN Recommendations on the Transport of Dangerous Goods (Orange Book,3'd edition, 1999) where a set of criteria is compiled to evaluate the need for classification of materials as oxidising substances. According to the criteria as described in the above mentioned UN document:

• the classification procedure using experimental testing need not be applied for organic compounds if the compound does not contain oxygen. fluorine or chlorine. AND
• 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 chemicallv bonded onlv to carbon and hydrogen.

BLUES GS 5664.80 is a mixture of several structural related compounds, that contain chlorine and oxygen. Chlorine is bonded to carbon only, whereas part of the oxygen atoms are bonded to sulphur. Thus, the conditions of the UN recommendations are not fulfilled and the oxygen balance was used as third criterion to predict oxidising properties:

The oxygen balance of BLUES GS 5664.80 as calculated for the main compound according to the UN recommendations and taking carbon, hydrogen and oxygen into consideration, was found to be negative. ln principle this means, that there is a surplus on carbon atoms for a complete reaction according to the following reaction scheme:

CxHyOz + [x+(y/4)-(z/2)]O2 --> xCO2 + (y/2)H2O.

Conclusion

Based on the internationally recognised UN Recommendation criteria and on the oxygen balance, BLUES GS 5664.80 is considered 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 BLUES GS 5664.80 is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.
