Sodium hydride is a strong base which
reacts nearly spontaneously when exposed to water forming sodium
hydroxide and hydrogen gas. Thus according to Annex XI part 2, it is not
technically feasible to test for hydrolysis.
Sodium hydride is an inorganic compound
and therefore the biodegradadtion endpoint is waived in accordance with
column 2 of REACH Annex VII. Further data on biodegradation are also not
possible to generate due to the substance being inorganic, and water
The data bioaccumulation for sodium
hydride is waived in accordance with REACH Annex XI, the study is not
technically feasible because the test substance is reactive with water.
Once this substance has reacted with water it produces sodium hydroxide
and hydrogen gas. Sodium hydroxide is highly water soluble and therefore
will not bioaccumulate.
