Description of key information

NMMO is concluded to be highly flammable when ignited, based on the results of the EC A.10 test conducted under GLP; furthermore, NMMO is concluded not to be pyrophoric, nor flammable in contact with water following GLP studies in accordance with EC test methods A.12 and A.13 (Younis, 2012). 

Key value for chemical safety assessment

Flammability:
highly flammable

Additional information

Justification for classification or non-classification

NMMO was determined to be highly flammable in the EC A.10 test. From the EC A.12 and A.13 tests it is concluded that NMMO is not be pyrophoric, nor flammable in contact with water.

DSD: NMMO should be classified as a highly flammable solid (F symbol) with risk phrase R11: Highly flammable.

CLP: NMMO should be classified as a category 1 flammable solid with hazard statement H228: Flammable solid. This is a conservative approach as only EC A.10 test results are available.
