Is sodium hydride toxic?

Sodium hydride is generally non-toxic but highly corrosive. Direct contact can cause skin burns and significant damage to the skin and mucous membranes. Appropriate personal protection should be taken when handling sodium hydride.

Sodium hydride is an inorganic compound that appears as a white or grayish crystalline powder. It is primarily used as a condensing agent and catalyst, and also finds applications in the pharmaceutical, pesticide, and polymer industries. While sodium hydride itself is not toxic, it is strongly corrosive. The fumes it emits can irritate the eyes and respiratory tract. Direct skin contact may result in burns, and ingestion can cause severe injury to the digestive tract. When handling this substance, proper protective measures must be taken, including wearing a respirator, rubber gloves, and protective clothing. If skin contact occurs, immediately remove contaminated clothing and rinse the affected area with flowing water for at least 15 minutes, then seek medical attention promptly.

In addition, sodium hydride has high chemical reactivity and can even ignite spontaneously in moist air. Heating or contact with acids may lead to combustion or explosion. Extreme caution must be exercised when handling sodium hydride.
