Continuity mistake: On the roof at the studio, Wally sets up John's gear and anchors his rappelling line onto a single carabiner which is attached directly to the belt support around John's waist. Yet when Johnny flips upside down while rappelling down, in the closeups when Roy joins him, that carabiner is now locked off onto another carabiner, which is attached to John's belt, and both of their locking mechanisms are red. Then when John's on the ground, the carabiner attached to his belt and anchor is entirely silver.
Continuity mistake: When Roy and John are at the studio so John can test out Wally's rappelling gear, on the roof John's wearing his medical holster, but Roy is not, but when each rappel down in the wide shots they're both wearing it. Then in their closeups while hanging on their lines, Roy's wearing his medical holster, but Johnny's has vanished, then on the ground Johnny's wearing his and Roy's has vanished.
Continuity mistake: At the studio, when Roy and Johnny are on the roof with Wally to test out Wally's rappelling gear, before Johnny rappels down the thin swami around Johnny's waist and the loop at the back are both green, but once he rappels down the swami belt is grey and the loop is blue.
Continuity mistake: When the woman from the car accident is in the ER, Brackett tells Morton to intubate her and Morton grabs the laryngoscope and slides her body down on the gurney to a proper position, but in the next shot from another angle Brackett orders the intubation again and the same things are repeated.
Continuity mistake: While the woman from the car accident is in the ER, when Brackett tells Morton to intubate her Morton has a penlight (to check pupillary response) in the pocket of his scrubs, but in the following shots that penlight keeps vanishing from his pocket and reappearing.
Continuity mistake: After Chet sees The Mouse run under the fridge, when the guys are discussing The Mouse Johnny's medical holster is clipped at his right hip, but when they're dispatched to 'man unconscious at laundromat' his medical holster is now at his left hip as he walks to the squad.
Continuity mistake: When Roy and John are at the nurses' station talking to Brackett and Dixie about The Old Engine, at the bottom right corner of the screen we can see the patient's metal clipboard chart being held, before Early even walks over to the nurses' station holding a chart. Then when Early does walk over he stands to Brackett's right, but in shots facing Dix and Johnny we still see that chart being held, where Roy is supposedly standing, not Early. Additionally, the charts hanging on the chart holder change/vanish between shots.
Continuity mistake: At the scene of the traffic accident involving the car and the armored truck, the chrome center of Squad 51's lightbar is backwards, the solid side is facing front and the vertical slats are facing the rear.
Continuity mistake: While cutting the shaft where the burglar is trapped, in the close-up of Johnny taking the K-12 from Roy we can see the ladder that Roy's standing on, and when it cuts back to Roy after Cap's closeup, the ladder Roy's standing on has switched around to the opposite way.
Continuity mistake: While John's lying in the lateral tunnel when digging to reach Helena, his entire uniform is covered in dirt, but when John pulls her out and is with Roy in the rescue shaft, John's uniform is only a little dirty, nowhere near as filthy as it was just moments before.
Nurse's Wild - S1-E7
Continuity mistake: At the liquor store, when Roy is seeing to the store owner with chest pains, Roy snaps a black headed lead onto the disc, but in the man's closeup it's a white headed lead. Then when Brackett orders countershock, the lead is back to black.
Continuity mistake: At the airport, when Roy is being told about young Frankie flying the airplane because his father had a heart attack, we see that Roy's wearing his uniform shoes, but in the shot of Roy following the airport employee while they're running into the building, Roy (perhaps his double) is wearing tan work boots. The uniform shoes are back when Roy uses the grounded plane's radio mic.
Continuity mistake: After Squad 51 is dispatched to "possible heart case" when Roy and Johnny walk into the house, we can see in the hallway and there's a bureau against the wall, but when they leave that bureau is gone and now there's a painting on the wall which we should have seen in the earlier shot, but it wasn't there.
The Wedsworth-Townsend Act - S1-E1

The Wedsworth-Townsend Act - S1-E1

The Wedsworth-Townsend Act - S1-E1

Continuity mistake: At the scene of the traffic accident, after removing the injured driver from the overturned tanker, when Roy gets the Biophone from the squad and John runs over to the ambulance stretcher, notice the red rectangular material adhered to the front of Engine 51's cab. We know that Engine 51 does not have a license plate on the front of its cab, and during this scene Engine 51 is being played by the real Engine 127, whose license plate is at the front of its cab.
Continuity mistake: When Roy brings the injured tanker driver into the ER, the attendants wheel the stretcher down the hallway passing treatment 3, and after Roy asks Brackett and Early a pointed question about the trucker's condition, the doctors also walk down the hallway passing treatment 3, in the direction of the nurses' station. But then we see that Early and Brackett are with the patient in treatment 3, which is right beside the ER's receiving entrance.
Continuity mistake: When Station 51 is being dispatched to the brush fire, there's black tape on the chrome trim of the squad's lightbar, but when Squad 51 arrives on scene the black tape has vanished. Then later at Rampart, after Brackett calls Roy a hose jockey, the black tape is back, but vanishes again when they rescue the injured looter.
Cook's Tour - S1-E4
Continuity mistake: While Early is trying to remove a young boy's hand from a vase, in the shot from inside the room he's in treatment 3 with a windowless door, but when he steps into the hallway and asks Sharon for ice cubes he's at treatment 5 with a window on the door.
