Agent Name
Sodium hydride
Synonyms
NaH; Sodium monohydride; UN1427; [ChemIDplus]
Description
Gray powder in oil with a kerosene odor; [CHRIS]
Sources/Uses
Used as a condensing and reducing agent, e.g., to descale metals by reducing metal oxides; [HSDB]
Comments
Can cause third-degree burns after short contact; [CHRIS] Highly corrosive to skin, eyes, and respiratory tract with risk of acute pneumonitis and pulmonary edema after high inhalation exposure; reacts with water to form sodium hydroxide and hydrogen; [HSDB] Hydrides are one of the four binary salts that have specific hazards (nitrides, carbides, hydrides, and phosphides); Hydrides give off hydrogen, and a corrosive base is formed from contact with water. The corrosive base is the hydroxide of the metal that is attached to the hydrogen in the hydride compounds; [Burke, p. 21]
