Key value for chemical safety assessment

Flammability:
flammable

Additional information

Flammability of methanol:

Based on the measured flash point of 11°C and the boiling point of 122°C, methanol is highly flammable. Based on the chemical structure and experience in handling and use, pyrophoricity and flammability in contact with water are not expected.

Flammability of the parent substance:

There are no measured data for the flammability of the parent substance, but since it is comprised of ca. 40% w/w silane and ca. 60% w/w methanol, the flash point is expected to be similar to that of neat methanol. Therefore the parent substance is expected to be highly flammable.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability in contact with water are not expected.

Self-heating: the substance is a liquid and a liquid does not demonstrate self-heating purposes, unless it is absorbed on a large surface.

Justification for classification or non-classification

The available data on the flash point and the boiling point of the test substance meet the criteria for classification as highly flammable liquid cat. 2 (H225) according to Regulation (EC) 1272/2008.

 

The available data on pyrophoricity and flammbility in contact with water of the test substance do not meet the criteria for classification and are therefore conclusive but not sufficient for classification: Based on the chemical structure and experience in handling and use pyrophoricity and flammability in contact with water are not expected.
