Toxicity of gaseous ammonia

The handling of ammonia safely has been discussed by Brandt(Ref 40) and the toxicity of ammonia fumes by inhalation,by Wheatherby (Ref 55). Ohno(Ref 57) noted that the toxicity of gaseous ammonia was much smaller than that of sulfur dioxide. Both gases produce irritation of mucous membrane and eyes, bronchitis, hyperemia, hemorrage, endema, exudation and pneumonia. Krop(Ref 58) lists the toxicity and health hazards of ammonia and other substances used as fuels in rocket propellants[Also see Sax(Ref 82) for additional information on the hazards of ammonia]...
