Maybe -- hypothetically -- more than depressurizing the main shuttle bay: look how little time he had to explain and how many buttons he presses with his unhuman super speed; maybe he didn't have time to explain that he quickly added as much preassure as he could (remember passed scenes of how quickly oxygen could be brought back to an deoxygenized Bridge, or how quickly fresh air coudl be cycled) before opening the bay door, which could add more kick. Also, he could have opened connecting doors to the main bay, to add what little was there.
Of course, how come none of the shuttle in the bay are blown out? What's holding them to the floor? 'cause nothing apparently is holding them, because we've seen episodes where somebody can steal a shuttle and the only thing he has to worry about is getting the bay door open.
And what about shuttle bay crew? Everytime we see a shuttle bay, it seems there's crew doing maintainence. Floating flotsam?
The needs of the many... They were counted as acceptable casualty...
