Description of key information

Flammable solid.
The substance has no pyrophoric properties.
The substance liberate flammable gases in contact with water.
The substance is a self-reactive substance or mixture.
The substance is not a self-heating substance or mixture.
The substance is not an organic peroxide.

Key value for chemical safety assessment

Flammability:
contact with water liberates highly flammable gases

Additional information

Under the test conditions of UN-Recommendations on the Tranport of Dangerous Goods, Manual of Tests and Criteria, 2nd revised edition, Part III, Test N.1, Sub-section 33.2.1.4, the test substance is found to be a flammable solid .

In contact with water the substance liberates hydrogen which did not ignite spontaneously, but the rate of evolution of flammable gas is greater than 10 litres per kilogram of substance over one minute.

Under the test conditions EU method A.13 and GLP the test substance was found to be non-pyrophoric as it did not spontaneously ignite.

The substance neither detonates nor deflagrates at all and shows low effect when heated under confinement.

The test substance is considered to exhibit a danger as self-reactive substance in the

sense of the regulations. A SADT of 50.0°C results from these data.

The substance or mixture does not need to be classified as self-heating as the substance is a solid with a melting point below 160°C.

The substance or mixture does not need to be classified as an organic peroxide as by definition based on their chemical structure the substance is no organic peroxide.


Flammability additional key value for CSA: highly flammable

Justification for classification or non-classification

The substance has to be classified as F; R11 Highly flammable under Directive 67/548/EEC and as Flam. Solid 1: H228: Flammable solid according to Regulation (EC) No. 1272/2008.

The substance has to be classified as F; R15 Contact with water liberates extremely flammable gases under Directive 67/548/EEC and as Water React. Flam. Gas 1: H260: In contact with water releases flammable gases which may ignite spontaneously according to Regulation (EC) No. 1272/2008.

The substance has to be classified as Self React. Type E: H242: Heating may cause a fire according to Regulation (EC) No. 1272/2008.
