Description of key information

Following a GLP study in accordance with test N.1 of United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Fifth revised edition, 2009, cerium trichloride needs not to be classified as a flammable/readily combustible solid (Tremain, 2013). From day to day handling of the substance, cerium trichloride is concluded not to have pyrophoric properties nor to be flammable in contact with water.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

Pyrophoricity.

In the daily use and handling of cerium trichloride during which continuous exposure to air can occur, no spontaneous ignition is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that cerium trichloride

has pyrophoric properties.

Flammability in contact with water.

Under conditions where cerium trichloride is in contact with water no ignition and/or liberation of flammable gases is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that cerium trichloride is flammable in contact with water.

Flammability.

From a readily combustible solids test (UN N.1) cerium trichloride is concluded not to be a flammable/readily combustible solid (Tremain, 2013). This results in an absence of classification both under DSD and CLP systems.
