Continuity mistake: When Squad 51 heads out on the first call, Roy pushes the tool cart up against the wall map and the rear apparatus bay door is down, but in the next wide shot as they head down the driveway, the tool cart is gone and the rear door is raised all the way up.
Continuity mistake: When Early is examining the boy who had the grand mal seizure in the waiting room, after using his penlight Early puts it back into his pocket just before he examines the boy's ears in the closeup, but in the wide shot that penlight is on the gurney and Dixie picks it up then puts it into her pocket. Yet in Early's closeups the penlight is still in his pocket, and in the wide shots it's gone.
Continuity mistake: When Early examines the boy who had a seizure in the waiting room, Early uses a tongue depressor and his penlight to check the boy's throat. During his examination, in the wide shot the penlight is in Early's right hand and the tongue depressor in his left, but in the closeup they've switched hands. Additionally, in that wide shot Dix is holding the otoscope with her right hand, but in the closeup her right hand in under the boy's head.
Continuity mistake: Dispatched to the structure fire are Station 51, Engine 36, Engine 116, and Truck 3. While Johnny and Roy are searching the rooms for the young girl, it cuts to a shot of guys from 9, and later there are also shots of 28's and 19's guys, even though none of their companies were called to this incident. These are shots from previous episodes including 3x7, "Promotion."
Continuity mistake: When Station 51 is dispatched to the landslide, the address is given as 2283 Canyon Road, but when they arrive at the house the address is 4102.
Continuity mistake: When Ruthie is wheeled into the ER, Dixie tells the attendants to put her in the treatment room where Dr. Early's waiting, and they wheel her into treatment 2 which has a windowless door, but when they're in the room the door has a window, which means she's in treatment 1, not 2. Plus the fact that both treatment rooms are set up differently.
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 guy who was injured in the manhole is brought into the ER, Dix tells them to bring him to treatment 6 (which is around the corner from the other treatment rooms, and has no color lines that run past its door), then we see him wheeled into treatment 6 in the shot from the hallway. However, in the next shot from inside the treatment room we can see they're not in treatment 6, but actually in treatment 1, note the red, green, and yellow lines on the hallway floor in front of its doorway, and treatment 6 has no color lines that run past its doorway.
Continuity mistake: When the TV catches fire in the kitchen, Captain Stanley unplugs it, and when it cuts to Roy running into the kitchen with the fire extinguisher, he passes Marco, who just ran into the apparatus bay. All of this while we hear Cap's voice telling Marco, who already ran out, to get the asbestos blanket. Then, in the next shot, Marco is still standing behind Captain Stanley in the kitchen.
Continuity mistake: When Johnny's on the phone with Uncle Ernie about the new color TV, in the wide shot Johnny writes down the address of the warehouse, and puts the pen back in his shirt pocket. Then Johnny thanks Uncle Ernie, and when he hangs up the phone, in the next closeup the pen is back in Johnny's hand.
Continuity mistake: When the boy who fell over the cliff is brought into the ER, Dix tells them to bring him to treatment 3 and we see them at treatment 3's door, which is on the same side of the hallway as treatment 4, with the red line closest to it (hall has red, green and yellow lines on the floor which run the length of the hall) However, in the shot from inside the treatment room, they're not in treatment 3, but are actually in treatment 1. Note that we see treatment 4 directly across the hall, which means they're in treatment 1, and also see the yellow line is closest to the door which means it's on the opposite side of the hallway.
Continuity mistake: On the way into the treatment room with the unconscious boy, Gage is on the left side of the gurney holding the IV bag. Suddenly, he's on the right side, away from the bed.
Continuity mistake: Squad 51's lightbar has a center chrome piece which has slats at the front and is solid at the back. When the squad's dispatched to the vehicle accident with the two student drivers, on scene the lightbar's chrome center is on backwards, it's solid at the front for some inexplicable reason.
Continuity mistake: After Roy gets his leg bandaged at Rampart, as he and Johnny exit to their truck, they suddenly get haircuts. Looks like a shot from an earlier season.
Continuity mistake: When Station 51 is dispatched to a structure fire (with the two girls trapped upstairs) the address given is 1911 Harper Ave, but when they reach the house with the fire, directly across the street that house number is 1637.
Continuity mistake: When the unconscious boy is brought to the ER, he's taken into treatment 2, with a windowless door, but when Early is doing the lumbar tap on the boy, the door behind Early has a window, and also by the way the room is set up, we know it's treatment 1 he's in, not 2.
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.
The Girl on the Balance Beam - S5-E18
Continuity mistake: When Roy and Johnny arrive on scene with the injured gymnast, as they enter the building in the exterior shot it's the last door that's open, but in the next interior shot that last door is shut, and it's the second to last door that's open.
The Girl on the Balance Beam - S5-E18
Continuity mistake: When Johnny and Roy are at the movie studio, while they're dangling from their lifelines they're trying to help the actress dangling from her own lines, but when she freaks out she drops her wand (yes, a wand) in the wide shot, but next closeup she's still holding it.
Above and Beyond... Nearly - S5-E20
Continuity mistake: After Station 51 is dispatched to 'man stranded on a cliff', when Roy and John free climb up the cliff, they're not wearing their uniform shoes, they're wearing hiking-type shoes with ridges on the soles.
