Additional information
No aquatic toxicity data are available for Sodium hydride due to the potential for the compound to react with water. Sodium hydride is a strong base which reacts nearly spontaneously when exposed to water forming sodium hydroxide and hydrogen gas (flammable).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
