But surely not in miliseconds like opening a set of valves in a hypergolic abort system (ie superdracos)... What do you use to spin up the turbines? Helium?

Distance from fireball is 0.5*a*t^2, so if t is small, you haven’t moved far even if a is high. At ~6g thrust, you’ll only travel ~0.03m in 100 ms. Pressure wave (aka explosion) with liquid rockets is low, as ox & fuel are poorly mixed. If you can fly out of it, you’re prob ok.
