SODIUM AMIDE is a powerful reducing agent. Reacts violently with oxidizing agents. Reacts violently with steam and water to form caustic NaOH and NH3 vapors [Bergstrom et al., Chem. Reviews, 12:6 1932]. May form explosive compounds in the presence of water and carbon dioxide [Handling Chemicals Safely 1980 p 826]. Liable to deflagration upon heating and friction. Forms an explosive peroxide on storage. When sodium amide and chromic anhydride are mixed together a vigorous reaction results; the same occurs with other oxidizing agents including dinitrogen tetraoxide, potassium chlorate, sodium nitrite. [Mellor 11:234 1946-47]. Reaction with 1,1-diethoxy-2- chloroethane produces sodium ethoxyacetylide, which is extremely pyrophoric [Rutledge 1968 p. 35]. Reactions with halogenated hydrocarbons may be violently explosive. Sodium amide forms toxic and flammable H2S gas with CS2. (714).

Storehouse ventilated at low temperature and dry; stored separately from acid and alkali; moisture-proof

Reacts violently with water, generates flammable gas, may explode

Stability Flammable. Reacts violently with water producing very toxic fumes. In case of fire do not use water, but instead smother with soda ash. May form explosive peroxides if heated, or if stored for extended periods in contact with air or oxygen. Incompatible with water and aqueous solutions, carbon dioxide, halogenated hydrocarbo

Excerpt from ERG Guide 139 [Substances - Water-Reactive (Emitting Flammable and Toxic Gases)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

Neutralizing Agents for Acids and Caustics: Caustic solution formed by reaction with water can be diluted with water and/or neutralized by acetic acid. (USCG, 1999)

FLAMMABLE, DANGEROUS FIRE RISK.|The reduction with 1,1-diethoxy-2-chloroethane in the presence of ammonia produces sodium ethoxyacetylide, which is extremely pyrophoric. Sodium amide reacts violently with water and frequently bursts into flame.

INTENSELY IRRITATING TO SKIN, EYES, MUCOUS MEMBRANES.

Ammonia gas formed by reaction of solid with moisture irritates eyes and skin. Solid causes caustic burns of eyes and skin. Ingestion burns mouth and stomach in same way as caustic soda and may cause perforation of tissue. (USCG, 1999)

INGESTION: give water or milk followed by dilute vinegar or fruit juice; do NOT induce vomiting; call a doctor. SKIN OR EYES: flood all affected areas with copious amounts of water. (USCG, 1999)
