Continuity mistake: At the start, when Chet tacks the notices up on the bulletin board, the papers are tacked to the board differently between the closeups and wide shots.
Continuity mistake: At the apartment complex fire, after Truck 82 sets its outriggers, Engine 28 is right behind them with their supply line and duals laid out, but quite a few shots later Engine 28 is just pulling up behind 82, even though they were already there all set up.
Continuity mistake: After the ambulance is involved in a traffic accident, when Marco shows up in Squad 51, he parks it parallel to a blue pickup truck and gets out of the squad, but in the next shot that pickup has suddenly vanished and the squad is now parked beside the sidewalk.
Continuity mistake: In the waiting room, after Mrs. Evans complains that she's been waiting in the ER for two hours, Dixie walks up the hallway to Brackett, who's beside treatment 1, but after Brackett tells her about the visiting administrators, Dixie walks away headed toward the nurses' station. Yet in the next shot, Dixie is back at the opposite end of the hallway, by the waiting room, as she heads up the hallway before the man walks in with his injured son.
Continuity mistake: When the dispatcher sends Squad 51 on an 'unknown type rescue', the address is given as 2608, but when they're at the house the address is 4654.
Continuity mistake: During the fire at the apartment complex, when Cap talks to dispatch over the HT and requests a second alarm, we see Roy put up that first ladder, but after the Pasadena engine arrives, Roy's just putting up that first ladder. Second, after Engine 82 extends their outriggers, it cuts to the flames and we see that three ladders are already against the building, but then there are only two up - the third will go up a few shots later (when Roy reaches the balcony) Third, we see Roy start climbing the ladder that's farther from the camera (the one Johnny's holding), but when Roy reaches the balcony, he's climbing up the ladder that's closer to the camera.
Continuity mistake: When Station 51 is dispatched to 'plane crash into a structure' the address is given as 1145 Delmar Drive, but when they arrive at the apartment complex, the 3-storey structure's address is 775.
Continuity mistake: When Herbert is leaving the station, there are shots of him on the left edge of the bay doorway, but in the shots of the guys looking at Herbert, particularly Chet and Marco who are standing in front of the squad, it's as if Herbert is crawling around towards the center of the bay doorway - their eye contact is way off.
Daisy's Pick Blind Date - S4-E7
Continuity mistake: While Roy, Johnny, and Cap are in the ice house with the hypothermic victim, there's a closeup of the pipe's frozen shut-off valve in the upright position with an ammonia leak, and the manifold temp/pressure gauges that are hanging from it. Then, when Johnny goes to wrap the rag around the valve it's upside-down, but in the next shot the valve is upright once again, and the manifold gauges are now facing the opposite way.
Continuity mistake: When 51's guys get to the roof of the building with the swaying sign, Marco places the silver hose roller on the roof edge, but when Captain Stanley and Stevie's father lean over the edge to talk to Stevie, the second larger hose roller is already in place near the silver hose roller, even though the second one hasn't been brought to the roof yet by Engine 95's guys.
Continuity mistake: Just after Brackett tells Early that the patient he was talking to is his father, it cuts to a shot of Squad 51 pulling up the driveway, and the Engine 51 we see parked in the apparatus bay is not the current Ward LaFrance pumper, it's the original Crown engine from seasons 1 and 2.
Continuity mistake: When 51's guys are at the table eating and discussing Roy and Johnny's deal, Johnny tosses his car keys to Roy, and in the following shots those keys vanish and reappear on the table repeatedly, and in the shots where the keys appear on the table, it's the ketchup, mustard, and napkins that have vanished. Also notice that the ketchup's brand name is covered.
Continuity mistake: While Johnny is trying to reach the man who fell over the cliff, the bicycle falls all the way to the bottom of the canyon, and then there's a shot of the man and we can see that the bicycle is still above him at the side of the cliff, just before Chet says over the HT, "Lower him, Cap, the victim's broken loose."
Transition - S4-E15
Continuity mistake: After Gil and Johnny have lowered the man from the amusement park ride, Gil, who's wearing the backpack, rappels down first and reaches the ground. Then when Johnny hooks in and rappels down, there's a shot of what is supposed to be Johnny rappelling down, but it's actually a shot of Gil, because it was Gil who was wearing the backpack.
Continuity mistake: After Squad 51 gets back to the station, Roy and Johnny remain in the squad discussing Roy being the coach, and when the dispatcher drops the tones, we see a closeup of five pair of legs rushing out of the kitchen, even though we should only be seeing four pair of legs, since Roy and Johnny are already in the squad.
Camera Bug - S4-E10
Continuity mistake: After Roy and Johnny are dispatched to Station 68, Bob is lying on the floor with his shirt buttoned up and Roy has his hand on Bob's chest taking his respiration, but when it cuts to Bob's closeup his shirt is already unbuttoned, with the ECG electrode discs and leads in place on his chest. Additionally, in Bob's closeups the leads go from attached to the discs, to unattached, to attached again.
Continuity mistake: When Johnny and Roy are with the boy who is in anaphylactic shock from the bee sting, Johnny's watch reads 2:25, then 2:35, and then 2:25 again.

Continuity mistake: During the fire at the chemical plant, the distinctively marked SCBA tanks that Captain Stanley, Johnny and Roy are wearing, when they're searching for the missing man, change when they're inside and then finally exit.
