 == Nontoxic == 

 In the image caption, HAN/AF-M315E is referred to as ""a nontoxic ... liquid"", but in the HAN article it's referred to as toxic, corrosive and possibly carcinogenic. The reduced toxicity is only in relation to hydrazine and similar fuels. Mainly that it doesn't produce toxic vapour when being handled, either directly or by reacting with handling materials. It doesn't refer to the material itself. Can I suggest removing the word ""nontoxic""?    "
