Description of key information

Waiving: not technically feasible

Key value for chemical safety assessment

Additional information

Sodium hydride is a strong base which reacts nearly spontaneously when exposed to water forming sodium hydroxide and hydrogen gas. This endpoint is therefore considered technically not feasible and waived in accordance with REACH Annex XI, part 2.
