Description of key information

Lithium nitrate was non-flammable in the conducted study. 

The chemical structure of lithium nitrate does not contain chemical groups, which may lead to the conclusion that the test substance is capable of developing a dangerous amount of (flammable) gas in contact with water.

Further, lithium nitrate does not contain any chemical group that might lead to spontaneous ignition shortly after coming into contact with air at room temperature (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, EU-Document (2012)).

The experience in handling and use does not indicate flammability upon contact with water or pyrophoric properties.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

A flammability test for solids was performed with lithium nitrate according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, N1: Test Method for readily combustible solids, sub-section 33.2.1.4. The study supports the expert statement regarding the flammability of lithium nitrate. Lithium nitrate was non-flammable in the test. (FMC, 2012)

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on available data on flammability, the test item is not classified according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.
