An Ounce of Prevention - S6-E13
Plot hole: As Roy and the stagehand are bringing in the equipment to treat the shock victim Engine 51 rolls into the scene. Not enough time has passed for the engine to respond. They haven't even started treating the victim yet.
Suggested correction: First, Cap and other guys at Station 51 were watching the live TV show, then heard the explosion happen live, so Engine 51 rolled out immediately and notified dispatch. Second, we don't know how far the set of the Tom Jensen Show is from Station 51. It cannot be a plot hole since we don't have the necessary information. All we know is Roy and John were cleared for 90 minutes. Third, when Jensen tells his live audience, "What you're witnessing is remarkable" John has already begun treating the victim with mouth-to-mouth resuscitation, while Roy and Jensen's guy go to wherever Squad 51 is parked outside, to get the stowed paramedic supplies. Then the shot dissolves (we don't know how much time goes by - 2, 3 minutes?) and cuts to Engine 51 arriving on scene, as Roy and Jensen's guy return with all the gear.
Engine 51 cannot just roll out since they saw it live. If they were the closest to the show, they would need to be dispatched to the fire. As we don't know where the show is, there may be another station closer.
Captain Hook - S6-E8
Other mistake: As the fire apparatus are leaving the station for the helicopter rescue, the shot from the front shows doors at the back of the building but when they are leaving it shows a brick wall at the back of the building.
Suggested correction: When Station 54 are leaving for the "aircraft down" rescue, in the exterior long shot from across the street (of the real Station 127), we are not seeing the apparatus bay with a head-on frontal view. The camera is positioned so that viewers see the apparatus bay at an angle, and we are only able to see the very long interior left brick wall, with the doors to locker room/bathroom and the dorm. The back of the building with the rear roll-up door is simply not visible at this particular angle.
Other mistake: Stoker prematurely plots 617 Kimble Road on the map as the dispatcher is barely starting to say the address. Then the squad leads in the departure from the station, but when the squad arrives to the above dispatched location the engine is already finished with the dumpster fire.
Suggested correction: 1st part of the mistake is already noted and 2nd part is incorrect. The Engine and Squad are dispatched to 617-1/2 Kimball for unknown type rescue and Squad leads. At the destination, Captain Stanley walks to the front door and rings the bell, while off camera Roy and Johnny get rescue gear and join Stanley at front door. Dispatch then sends the Engine to a trash container fire at Farber/Wilmington, while Roy and Johnny's Squad stays with the current rescue involving dieffenbachia. After this, the Squad joins the Engine.
Other mistake: When the plane crashes into the neighborhood and traps Gage and DeSoto in the house, you see outside shots of the squad when the other two paramedics arrive. You can see a large piece of smoking engine/plane laying on the back end of the squad, right over the spare air tanks. They would have exploded when something that heavy and hot landed on them, since they are filled with oxygen. The tanks would be full or they would not be on the back of the squad.
Suggested correction: Probably air tanks, because oxygen tanks are always painted green. Both kinds of tank are very tough. Hard to tell with how much force the plane debris might have landed except that the truck still looks pretty much intact. However, if the plot required it, I would find it completely believable that the crash could have exploded the tanks, but also don't find it strange that they didn't explode.
