Description of key information

It is pyrophoric once isolated from solvent/volatiles and the aluminum-methyl bonds react violently with water releasing flammable methane gas.

Key value for chemical safety assessment

Flammability:
pyrophoric

Additional information

It also reacts with water emitting flammable gases (methane).

Justification for classification or non-classification

It is pyrophoric once isolated from solvent/volatiles and the aluminum-methyl bonds react violently with water releasing flammable methane gas.

It also reacts with water emitting flammable gases (methane).
