Continuity mistake: When Station 51 is dispatched to the 'unconscious female in a car' it's 8:20, but when Roy is on the Biophone with Rampart his watch reads 11:05, and John's watch reads 12:30 as he's checking the woman.
Continuity mistake: When dispatch drops the tones at night, waking all the guys up, notice that Marco's mustache has vanished, though it reappears later. Additionally, they all get into their boots, turnout trousers, only white T-shirts, suspenders, and grab their dark jackets, but when the bay door opens they're dressed in their uniforms as they respond. Then at the fire they're in the turnout trousers, and Johnny and Roy are wearing the uniform shirts when working on the burn victim.
Visible crew/equipment: When Roy leans over Captain Stanley after he was electrocuted, the outline of Roy's mic transmitter is visible on the back of his shirt.
Continuity mistake: When Roy and Johnny get to the address in the canyon that has overgrown weeds and shrubs, in violation of county ordinance, Johnny is empty-handed when they knock on the front door, but when they're told to come in Johnny is now holding the large fire-code violation ticket booklet.
It's How You Play the Game - S4-E19
Visible crew/equipment: When Johnny and Roy get the car salesman out of the car with the tiger, and when Johnny gets into the ambulance with him, the outline of the mic transmitter is visible at the side of Johnny's shirt.
Peace Pipe - S2-E5
Continuity mistake: When Brackett and Officer Vince are in the ER with the drunk driver, Dixie cuts the gauze bandages from around his head, and they lie bunched up on the gurney beside him, but in the overhead shots as Brackett draws his blood the bandages are still around his head.
Other mistake: The Battalion chief assigns tanker 76 to assist engines 51 and 60 with the rescue at the canyon. However, it is tanker 44 that arrives.
Welcome to Santa Rosa County - S6-E10
Continuity mistake: When getting the climbers off the mountain, the Ford letters on the tailgate are muddy and blanked out, but are not in the scenes where they're transporting the climbers in the pickup bed.
Deliberate mistake: At the very end of the episode, Roy and John are walking back to the unit and the driver side mirror appears to be parallel with the unit. The driver would see their own reflection at best.
Continuity mistake: When the guys come out and are watching Herbert leave, they are all in their turnout pants. Stoker is wearing turnout pants with the blue jacket zipped. When the tones drop for the call, the guys go to the vehicles and grab their turn out jackets and Stoker is in his blue pants and blue shirt pulling on a turnout coat. Not turnouts and no navy jacket.
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.
Continuity mistake: When Roy and Johnny go to get on the helicopter they are with only the orange bio-phone, but after The Boat brings them back to the shore you see them running to the helicopter with the patients, and they pick up their large black trauma box. They didn't have it with them when they left.
Continuity mistake: When transporting the heart attack victim from the plane the ambulance starts as a Ford and ends as a Chevy.
Continuity mistake: When Gage goes into the lion enclosure you see the lion up high roar with sharp white teeth but the other shots the lion is now an older lion with broken rotten looking teeth.
Continuity mistake: When Brackett leads Mr. Teal to his wife they walk into treatment 2, which has a windowless door, but in the shot from inside the room they're actually in treatment 1, which has a window on its door.
Continuity mistake: After winning the semi-finals against 16, when Chet walks into the kitchen in the closeups John's holding the newspaper filled with photos on the page facing out, but in the wideshots an entirely different page faces out. (00:45:00)
School Days - S2-E14
Continuity mistake: When Dr. Temple's assistant is running to the door to let the ambulance attendants in, as we see her exiting the room where the bookcase has fallen over, her slip is showing, but the very next room we see, her slip is properly under her dress.
Continuity mistake: Immediately before the man rescued from the sewer fire is brought into the hospital, the shot shows squad 51 and two ambulances in all three spots in the ambulance bay, however neither ambulance is the big box Mayfair type that was at the rescue scene. (00:11:20)
Continuity mistake: When the squad rolls up on the OD victim's residence Roy drives the squad over the little fence and bends it. When he takes off the gate is back in its original position.
Loose Ends - S6-E12
Continuity mistake: At the freight yard when the two men are talking to each other after the Montana man says that the operator has been a good friend, the front of the boxcar is seen, and some fire vehicles (a battalion car and a deluge) are visible on the left of the screen. When Engine & Squad 51 come on the scene, those fire vehicles have disappeared. (00:33:55 - 00:36:05)
