With the following statements taken from Wikipedia and backed by other
sites, I'm trying to make sense of a "MAN RATED" capsule having UDMH/NTO
motors right next to the escape hatch.


UDMH is toxic, a carcinogen <https://en.wikipedia.org/wiki/Carcinogen>
and can explode in the presence of oxidizers.
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 <https://en.wikipedia.org/wiki/Apple_juice>.
UDMH released into the environment can react in air to form
dimethylnitrosamine <https://en.wikipedia.org/wiki/Dimethylnitrosamine>,
a persistent carcinogen and groundwater pollutant

looks like a UDMH/NTO propellant.
