The way consoles explode, I don't think combustion with air has much to do with it. The fires afterwards, sure, but explosive consoles gonna 'splode, air or no. Really, extreme-environment suits, like Spock's in the new movie, would be the best protection.
Exploding consoles is more thermal damage than shrapnel, more often than not. More importantly, even 21st century space suits and are reinforced against micrometeoroid impacts and are effectively a form of low-grade body armor anyway. A 23rd/24th century space suit could be expected to have its own SIF or even forcefield protection for the same reason.
Shutting down artificial gravity would seem to be a safe bet too; no more bridge officers getting crushed by falling pillars.
How often does it happen that things just fall and hit folks? Usually it's stuff that exploded. Without gravity, it's going to fly across the bridge, hitting lots of people while ricocheting off walls and stuff.[/QUOTE]
Interestingly, a tumbling object in zero gravity only has so much momentum regardless of its mass; a grand piano tumbling through an open space in zero gravity packs a wallop, but a lot less than a ROLLING piano in the same space, which is accelerating at a constant rate instead of simply moving from a single brief impulse.
It's a tradeoff either way, but reducing the ship to vacuum conditions reduces the environmental hazards to that which could be found in open space itself, and those are somewhat easier to deal with if you have the right technology.
