Continuity mistake: When Johnny is writing the 'for sale' sign about his Land Rover, in the wide shot the two phone numbers begin with "853" and "352", but in the closeup a piece of paper has been glued over the phone numbers, and the new numbers now begin with "321" and "749."
Continuity mistake: When Brackett asks Early and Morton to assist with the examination of the hallucinating veteran, in the shot from the hallway the doctors walk into treatment 1, its door has no window, but when it cuts to the shot from inside the room, its door has a window, which means they're all in treatment 2 or 3, not 1.
Continuity mistake: When Johnny and Roy are heading to the parade in The Old Engine, and get sidetracked dealing with a fire rescue, they are wearing the old-style shirts with a ten-button, square bottom bib front, with five buttons on each side. When Captain Stanley laughs at them on the roof, their shirt style differs in the close-up, it's now a nine-button, pointy bottom bib, with four buttons on each side and one button at the bottom point.
Continuity mistake: While Johnny, Roy, and Vic try to outrun Charlene inside Stage 3, after heading down the ladder, when Roy opens the door to find Charlene standing there, Johnny's holding the red extinguisher in his right hand and the nozzle in his left hand, but next shot they've switched hands.
Continuity mistake: After leaving the football player who kicked in his TV screen, as Roy and John put the gear back in the squad, we see the old blue set of the Datascope 850 monitor and defibrillator, and not their current Datascope M/D2 white case. The last time the blue two-piece unit is even seen in the squad is in 4x13, "Parade", and the first time the white unit is used is in 4x15, "Transition", and it's then used in all following episodes. This scene was a prior taping, that was inserted into this end of the season episode.
Continuity mistake: When the Animal Control guys are dispatched to the fire in the canyon, the rearview mirror in their vehicle vanishes in the close-ups.
Continuity mistake: When Roy and John are talking to Vic at his party, his manager's cigar changes length repeatedly, from short to long and back again, depending on the camera angle.
Smoke Eater - S4-E16
Continuity mistake: When John and Roy are with the possible MI, while Roy's setting up the IV bag John's on the Biophone with Rampart, and after Brackett orders the IV TKO with MS, we see that Roy's pant leg has nothing on it, but then it cuts to the closeup and suddenly there are strips of torn tape (for IV as usual) on Roy's pant leg.
Smoke Eater - S4-E16
Continuity mistake: While John and Roy are treating the possible MI, when John's on the Biophone with Rampart his watch reads 5:10, but after the patient goes into V-fib John's watch reads 2:45.
Continuity mistake: During the structure fire at Kiddytime Toy Factory, when the man is downed by an electrical shock, Johnny pulls out the defibrillator and Biophone from the squad, and in Johnny's closeups with the Datascope we can see that its center knob on the right is missing, but in the Datascope's closeups the knob is back.
Continuity mistake: Roy and Joanne are going to be on a TV quiz show. When the guys are eating soup and sandwiches, Captain Stanley asks Roy, "You nervous about being on the tube tonight?" However, Roy didn't do the quiz show that night, because later we see they're on their next shift, and Roy is getting into his uniform when Johnny says "Tonight's the big night," and Roy tells him that Dwyer will do the rest of his shift when he leaves early.
Continuity mistake: During the fire at the apartment complex, when John and Roy go into the apartment to rescue the woman, they throw a coat over her, but then the explosion occurs knocking John and the woman unconscious. When Roy puts her over his shoulder and starts walking out the coat is not over her, but when he gets to the balcony she's covered by the coat, yet when the Pasadena fireman goes back for John, that coat is still lying on the floor.
Continuity mistake: When Brackett is first on the line with the vet, there's a closeup of Early checking the goat's heartbeat and we see the baby goat has been intubated. Brackett informs the vet of the goat's heart condition, so the vet tells Brackett to mask him with halothane and intubate. Then a minute goes by before the vet says that they should have him intubated by now, and when Brackett gets back on the line he says that the animal's intubated, even though we saw the animal already intubated in the closeup right at the start.
I'll Fix It - S4-E2
Continuity mistake: When Station 51 is at the scene of the oil well eruption, underneath a house which was built atop an abandoned oil field, just after Johnny tells Roy that he thinks the whole foundation is slipping, it cuts to a shot of the front porch as one of the porch columns (and part of another) breaks and falls. However, when the guys finally free the trapped man and carry him out, all the columns are upright once again.
Continuity mistake: When the guys decide to eat lunch before resuming CPR practice, Chet puts the CPR mannequin upright beside the fridge. Chet's wearing his regular black shoes, and the CPR mannequin is wearing white sneakers. However, in the close-up of The Mouse crawling under the fridge, the leg we see near The Mouse is wearing a brown rubber firefighter's boot.
Continuity mistake: After Johnny and the attendants exit the ambulance with Dora, the pregnant woman, the ambulance is empty and the drug box is on the seat with the Biophone on the floor beside the seat, but in the next shot as the gurney is wheeled inside, the drug box is now on the floor between the Biophone and seat.
Continuity mistake: When Brackett tells Dixie about the visiting administrators she's holding a clipboard, but when she's stopped by the man whose son has an arm injury, Dixie's now holding a brown folder.
It's How You Play the Game - S4-E19
Continuity mistake: At the scene of the vehicle accident, when Roy's on the Biophone with Rampart the squad's lightbar is on properly, the center chrome piece has vertical slats that face forward. However, after the victim is removed from his vehicle, when Johnny's on the line with Rampart note the squad's lightbar again, the center chrome is now on backwards, the solid side faces forward.
Continuity mistake: Before the fake eye test begins Captain Stanley hands each guy their own cheat sheet, and when Chet walks out of the day room upset about the eye test, John puts his cheat sheet into his shirt pocket just as they're being dispatched to the "accident and car fire." After the rescue, when John and Roy get back to the station John joins Chet by the lockers, and when John tries to prove that the eye test was a prank, John opens his locker and pulls out his cheat sheet, even though we saw him place it in his shirt pocket before the run.
Continuity mistake: When 51's guys go down into the tank to try and subdue Al, the big guy who has a chemically induced psychosis, the ring Al was wearing on his left hand in the overhead shots is gone, but when Al shakes Chet upside-down in the closeups the large ring is back, but then it vanishes again.
