UDMH is toxic, a carcinogen and can explode in the presence of oxidisers. It can be absorbed through skin. During the 1980s there was concern about the levels of UDMH in various foods being a cancer risk, especially for apple juice. UDMH released into the environment can react in air to form dimethylnitrosamine, a persistent carcinogen and groundwater pollutant.

Cool. C'est sympa d'en remplir des milliers de litres dans des boosters de premier étage.
