Continuity mistake: After Roy tells Johnny to call Barbara, while they're standing by the telephone in the kitchen, Squad 51 is dispatched to 'man unconscious at Observation Park', and when the squad rolls out of the apparatus bay, the engine we see parked in the bay is the Crown from the first two seasons, not the current Ward LaFrance.
Continuity mistake: When the parathion victim is brought into the ER, they go into treatment 2, but in the view from inside the treatment room when John opens the door to leave, we can see that he's actually on the opposite side of the hall facing treatment 2, which means he's in treatment 1.
Continuity mistake: At the start of the episode, when Roy and John are going through inventory in the trauma and drug boxes, there are three rolls on the trauma box lid and John takes two of them leaving only one, but it cuts to another angle and now there are two on the lid.
Continuity mistake: After John spots a cute nurse talking to Dixie, when he zeros in on Dix for the nurse's name Dixie's holding a pad in her left hand, but in the next closeup her left hand's empty as she gives John an entire run-down on that nurse.
Continuity mistake: When Dr. Early and Marcia's father stand outside her semi-private room, number 104, we see treatment 4 is right beside it. There are two problems with this bizarre situation. First, when Dixie gave Early the lab results about Marcia's possible pregnancy earlier, treatment 2 is right beside treatment 4, not the semi-private room 104. Second problem is that when Early and the parents walk into Marcia's room, in the interior shots we can see that there's a perpendicular wall right beside the doorway to its left, where the hallway ends. (00:19:20 - 00:31:30)
Continuity mistake: When Brackett's examining the teenager (Donny Most) with paralysis Morton's standing beside him, but in the next shot as Dixie takes the teen's BP, we see Morton standing behind the teen with the student nurse, then Morton's back beside Brackett.
Continuity mistake: At the station, after Johnny has searched through a bunch of papers for the receipt for $8.42, when he gathers them up a yellow paper falls to the floor at his feet, just before Roy suggests putting them in alphabetical order. Then after Johnny stuffs the papers in an envelope and tosses the envelope in the garbage, the paper that fell on the floor has vanished.
Continuity mistake: When Squad 51 is dispatched to a "man locked in a safe", at 1817 South Maplemoor, after the escape artist lets himself out of the safe, when Roy and Johnny head back to the squad the house address reads 4017.
Continuity mistake: When Station 51 is dispatched to an 'unknown type rescue', the woman who opens the door tells them she didn't call, and when Roy asks her if he and Johnny can check on her sick husband, Roy's second shirt button is open and his undershirt is visible, but in the next shot it's buttoned up again.
Continuity mistake: At the start of the episode, after Chet takes a spoonful of hot cheddar cheese the bowl is near his plate, but when it cuts to facing the other guys that bowl is on the other side of the table near Marco, then back and forth again.
Continuity mistake: When the boy who ingested ant poison is laid down on the gurney, the safety belt is wound around the gurney's side bar and clasped, but when exiting the house and loaded into the ambulance the safety belt is directly around the boy.
Continuity mistake: When Johnny goes to the closet to get the mop, because he's 'latrine officer of the day', he gets hit by the phantom, and all the guys run out of the kitchen to see Johnny wet again, so when dispatch drops the tones they all head for the vehicles and Captain Stanley removes his jacket. Then next shot all the guys are running out of the kitchen, as if they were all still there, and Stanley is wearing his jacket.
Continuity mistake: When Old Bill is wheeled into treatment 3, there's a pillow under his head and the gurney he's lying on has grey trim, horizontal bars under the bed and flat steel plates over the wheels, but when it cuts to inside treatment 3 as he's brought in, the pillow has vanished and the entire style of the gurney he's lying on is completely different.
Continuity mistake: After Station 51 is dispatched to 'man down' and realize it's Old Bill when they look through the window, when Roy and Johnny climb through the window their gear is handed in to them, and John takes the drug box with his left hand and Biophone with his right, but in the next interior shot John's taking them with the opposite hands.
Continuity mistake: Before Old Bill wakes up, Brackett, Morton, and Early are talking in the hallway outside Bill's room, and the hallway is a big, wide open space. After Bill wakes up, Dixie goes out to the hallway to get Brackett, and when they walk into Bill's room we can see the hallway behind them, and it's a fraction of the size it was before, only about 4-5 feet wide now.
Continuity mistake: After bringing Old Bill to the ER, when Squad 51 gets back to the station, in the shot of the squad driving backwards toward the driveway, the engine we see parked in the apparatus bay is the Crown from the first two seasons, not their current Ward LaFrance.
Continuity mistake: When Station 51 is dispatched to 'man down', Cindy and her mother are standing in front of the rear bay door, but they vanish in the next shot as the guys get ready to leave.
Continuity mistake: When Chet is being timed while putting on his gear, Squad 51 is parked much further up than the engine, providing more room in the apparatus bay behind the squad to run the drill. Then when Station 51 is dispatched to the explosion, the squad's parked normally. Additionally, we see the front bay door is closed, but that's impossible considering how far up Squad 51 was parked during the drill.
Continuity mistake: When Roy and John are in the ER's staff lounge discussing Donaldson, Roy's button, second from the top, is buttoned up in the wide shots, but is unbuttoned in his closeups during the conversation.
Continuity mistake: When Roy and Johnny are with the man in full arrest on the tower at the refinery, Johnny hooks up the Datascope with the wire, but in all the overhead shots there is no wire at the back of the Datascope monitor.
