Description of key information

Inorganic oxides in which the inorganic element is in its highest possible oxidation state are incapable of further reaction with oxygen and can thus be designated as non-flammable.

Tungsten is in its highest possible oxidation state (VI) in this compound and is incapable of further reaction with oxygen.

Therefore, this compound is not expected to be flammable or pyrophoric.
