Continuity mistake: In the scene where Jack rescues the worker from the warehouse, while lowering the victim - the rope is wrapped around the beam - but in the overhead shot as the floor gives way - the rope is only laying across the beam.
Continuity mistake: In the rope rescue scene, when they first arrive, the snorkel is nosed into the tiller truck right below the action. Then it disappears, then reappears in one of the final shots of that scene.
Continuity mistake: In the scene where the floor collapses at the grain facility, Jack's helmet comes off as he is falling, but in the next shot it appears back on his head for a split second as he continues to fall.
Continuity mistake: During the response to the apartment fire in the snow, one of the responding shots is of a new pumper and a fully enclosed new tiller truck, instead of the actual units which are quite a bit older.

Continuity mistake: In the scene at the abandoned building where the firefighter falls through the roof, when they rip the plywood off the door, you can see the whole piece of wood fall. But when the shot goes back to Jack as he opens the hose line, the plywood looks like it snapped in half and is still in the doorway.
