Without knowing the specifics of the incident: There is actually very little stored energy in a hydraulic system, due to the incompressibility of the fluid. Hydraulic injection injuries[0] are nasty, but catastrophic failure isn't particularly dangerous. Pneumatic systems on the other hand can reach dynamite energy levels and near-enough dynamite energy discharge rates. [0]A not-for-the-faint-of-heart google.
