If the console exploded at mid or upper torso, Leutre would of likely been thrown upper body first (head or back). If you combine the force needed to hurl someone backwards two meters, the fact engineering is a hard metal environment and that he didn't have a helmet on, I think it's very likely he would have at minimum a grade three concussion. That's assuming he wasn't immediately killed (which he wasn't according to Tom's post).
For those not familiar with basic medicine, a concussion of that magnitude causes unconsciousness for a very short period (less than five minutes), nausea, confusion, minor hallucinations (seeing stars), and amnesia.
