• Safety:
• Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. A poison by ingestion, skin contact, intraperitoneal, and intravenous routes. Moderately toxic by inhalation. An experimental teratogen. Other experimental reproductive effects. Human mutation data reported. A powerful reducing agent that is corrosive to the eyes, skin, and mucous membranes. May cause skin sensitization as well as systemic poisoning. Hydrazine and some of its derivatives may cause damage to the liver and destruction of red blood cells.

  Flammable liquid. A very dangerous fire hazard when exposed to heat, flame, or oxidizing agents. Severe explosion hazard when exposed to heat or flame, or by chemical reaction. Explodes on contact with barium oxide; calcium oxide; chromate salts; chromium dioxide; dicyanofurazan; mercury oxide; trioxygen difluoride; N-haloimides; potassium; silver compounds; sodium hydroxide; titanium compounds (at 130°). Potentially explosive reactions with alkali metals; NH₃; Cl₂; chromates; CuO; Cu⁺⁺ salts; F₂; metallic oxides; Ni; Ni(ClO₄)₂; O₂; liquid O₂; K₂Cr₂O₇; Na₂Cr₂O₇; tetryl; zinc diamide; Zn(C₂H₅)₂. Forms sensitive, explosive mixtures with 2-chloro-5-methylnitrobenzene; metal salts [e.g., cadmium perchlorate; copper chlorate (heat-sensitive); manganese nitrate (heat-sensitive); mercury(I) chloride; mercury(II) chloride; mercury(I) nitrate; mercury(II) nitrate; tin(II) chloride]; methanol + nitromethane; air; lithium perchlorate; sodium perchlorate; sodium. Ignites on contact with cotton waste + heavy metals; dinitrogen oxide; rhenium + alumina; catalysts; nitric acid; hydrogen peroxide; N,2,4,6-tetranitroaniline; rust + heat. Ignites spontaneously in air when absorbed on earth, asbestos, cloth, wood. Violent reaction with 1-chloro-2,4-dinitrobenzene; oxidants (e.g., iron oxide; chlorates; peroxides); thiocarbonyl azide thiocyanate. Vigorous reaction with benzene-seleninic acid or anhydride; carbon dioxide + stainless steel; copper oxide; lead oxide; potassium peroxodisulfate; ruthenium(III) chloride. On contact with metal catalysts (e.g., platinum black; Raney nickel; copper-iron oxide; molybdenum; molybdenum oxides; iridium), it decomposes to ammonia, hydrogen and nitrogen gases which may ignite or explode. A hypergolic reaction with dinitrogen tetraoxide is the basis of a liquid rocket fuel mixture. The vapor will burn without air. It is a powerful explosive. It is very sensitive and must not be used without full and complete instructions from the manufacturer for handling, storage, and disposal. Dangerous; when heated to decomposition it emits highly toxic fumes of NO_x and NH₃.
