Description of key information

The substance was determined to be 'not highly flammable' by ignition in a study performed in accordance with UN MTC Test N.1 and EC.A10  and in compliance with GLP.
The UN classification procedure for pyrophoric solids does not need to be applied because experience in handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures and because of the absence of structural alerts. For the same reasons, the EC A.13 test does not need to be performed. The substance has no pyrophoric properties. It was also concluded that the UN classification procedure for substances which may react with water to emit flammable gases does not need to be applied because: 1. experience in handling shows that the substance does not react with water; 2. the substance is known to be soluble in water; 3. the substance lacks structural alerts. The EC A.12 test does not need to be performed for the same reasons. The substance is not highly flammable in contact with water.
Based on structural features, the result of the DSC study and the auto-flammability study and on experience in handling, the substance is assumed to be not self-reactive.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

For substances showing no (propagation of) combustion, the EC A.10 test is essentially the same as the UN MTC N.1 test as wetted zone (N.1 test) is of no relevance then.

Statements rather than full studies were considered sufficient to cover the endpoints Flammability in contact with water and Pyrophoric properties. The statements were written by an expert in accordance with UN TDG-MTC Appendix 6 in compliance with the principles of GLP.

Justification for classification or non-classification

Justification for non-classification according to the CLP Regulations (EC) No 1272/2008:

Because Sodium ferrocyanide is not flammable by ignition, classification as a flammable solid is not necessary. 

Based on the absence of structural alerts and based on experience in handling, Sodium ferrocyanide does not have to be classified as a pyrophoric solid or as a substance which in contact with water emits flammable gases.

Based on structural features, study results and on experience in handling, Sodium ferrocyanide does not have to be classified as a self-reactive substance.
