How dangerous are RCS thrusters, in a vacuum, to A. other spacecraft, especially when docking, and B. astronauts in EVA suits? How far away do you have to be to be safe / do RCS thrusters need to be rigorously shut down and safed before an EVA is carried out near them? Does the gas from these very small hypergol engines expand quickly enough to be minimally hazardous if it impinges on something?
