Continuity mistake: When Roy and Johnny are in the apartment, just as Mr. Jefferson mentions that Shorty brought in hot tractors, it cuts to a closeup of Roy who is not wearing a stethoscope, but in the next shot the stethoscope is suddenly around Roy's neck.
Continuity mistake: When Station 51 is dispatched to the 'unconscious female in a car' it's 8:20, but when Roy is on the Biophone with Rampart his watch reads 11:05, and John's watch reads 12:30 as he's checking the woman.
Continuity mistake: When Roy and Johnny get to the address in the canyon that has overgrown weeds and shrubs, in violation of county ordinance, Johnny is empty-handed when they knock on the front door, but when they're told to come in Johnny is now holding the large fire-code violation ticket booklet.
Welcome to Santa Rosa County - S6-E10
Continuity mistake: When getting the climbers off the mountain, the Ford letters on the tailgate are muddy and blanked out, but are not in the scenes where they're transporting the climbers in the pickup bed.
Captain Hook - S6-E8
Other mistake: As the fire apparatus are leaving the station for the helicopter rescue, the shot from the front shows doors at the back of the building but when they are leaving it shows a brick wall at the back of the building.
Suggested correction: When Station 54 are leaving for the "aircraft down" rescue, in the exterior long shot from across the street (of the real Station 127), we are not seeing the apparatus bay with a head-on frontal view. The camera is positioned so that viewers see the apparatus bay at an angle, and we are only able to see the very long interior left brick wall, with the doors to locker room/bathroom and the dorm. The back of the building with the rear roll-up door is simply not visible at this particular angle.
Continuity mistake: After winning the semi-finals against 16, when Chet walks into the kitchen in the closeups John's holding the newspaper filled with photos on the page facing out, but in the wideshots an entirely different page faces out. (00:45:00)
Loose Ends - S6-E12
Continuity mistake: At the freight yard when the two men are talking to each other after the Montana man says that the operator has been a good friend, the front of the boxcar is seen, and some fire vehicles (a battalion car and a deluge) are visible on the left of the screen. When Engine & Squad 51 come on the scene, those fire vehicles have disappeared. (00:33:55 - 00:36:05)
Welcome to Santa Rosa County - S6-E10
Continuity mistake: In the scenes where Johnny and Roy are transporting the injured hikers in the back of the pickup truck, Roy's watch appears, disappears, then appears again.
Continuity mistake: When Johnny and Roy rappel down the cliff with the downed hang gliders, both of their lifebelts are buckled going from their left to right sides, but in Johnny's first closeups when he's with the second victim, Johnny's lifebelt is on the opposite way, note that it's buckled going from his right to left. Then once the glider falls Johnny's belt is on the original way.
Captain Hook - S6-E8
Character mistake: When Johnny and Roy are with the heatstroke victim in the polar bear costume, they're on different sides of the victim when Roy says, "Twitching here in both arms," and Johnny looks at her left arm and responds, "Yeah, the same thing over here too." And then it happens again, when Roy says, "Got some heavy spasms in these arms," and Johnny responds, "Yeah, same thing over here."
Continuity mistake: When Roy and Johnny begin rappelling down the cliff to the injured hang gliders, Roy's not wearing the safety pack in the closeup, but as they're rappelling in the wide shot the large safety pack is suddenly on Roy's back.
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.
Paper Work - S6-E11
Revealing mistake: After Roy and John meet the new supply nurse, when Squad 51 rolls back into the station the license plate number on the back of Engine 51 ends in 174, but the engine's plate number should read 999058. Engine 127's license plate number is 180174.
Continuity mistake: While Brackett and Morton are working on the boy who was shot with a pellet gun, when Morton is about to intubate the boy, we see that the O2 mask has been removed from his face and lying behind the boy's head, but when Morton hooks up the hose to the ventilator, we see the O2 mask and its elastic are still around the boy's neck. Then when Brackett says, "Prep him," the mask is gone.
Continuity mistake: While 51 is breaking into the bookie's apartment, after Chet uses the axe on certain areas of the door he puts the axe down, and in the shot from inside the apartment Chet reaches in through the hole on the door to undo the chain and remove the bar, but when the door opens there's another new axe mark over the top lock that was not made by Chet.
Continuity mistake: During 51's basketball game against 16, when Chet takes his first shot and makes the basket the scoreboard now shows 51's at 16 and 16's at 30, then Chet makes the second basket, but the scoreboard shows 51's still at 16 and 16's at 32.
