Continuity mistake: When Squad 51 is dispatched to the woman whose hair is caught in the meat grinder, time out is 12:34, and right after that quick run they stop by Rampart. Back at the station, after Chet mentions that when they started their shift that morning Boot was fine, they're all dispatched to the gasoline tanker traffic accident, and the time out is 9:18 in the AM. Then the next run Squad 51 responds to is the woman caught in the mixer, and the time out is 15:54.
Revealing mistake: During the rescue of the man trapped in the submerged car, when 110's Captain hands John and Roy (in the water) the special cave-in gear's air hose, then when he opens the O2 valve and also when he revs up the jaws, we see that The Boat's port side has a taught line tying it off at the stern in the closeups (seen from The Boat's deck) to prevent it moving, but in the long shots there is no line.
The Wedsworth-Townsend Act - S1-E1
Visible crew/equipment: At the very start of the episode, as the camera slowly passes the vehicles and the posts, the moving shadow of the camera is visible on one of the posts at the left as it moves past it.
Continuity mistake: During the rescue of the two boys on the tower, a few shots after Chet starts climbing the stairs, there's a long shot looking up at Roy and John, and we can see Chet at the last set of stairs at the bottom left of the screen, and a few shots later from the same long angle, we see Chet reach the top. However, quite a few shots later, after the old man comments about job security, we see Chet again, but he's nowhere near the top yet.
Continuity mistake: When Johnny and Roy must climb the tower to rescue the two boys, they both buckle the pompier belts around their waists with the large carabiner hooks at their left sides and walk towards the tower, but in the next shot Johnny's belt is on the opposite way, at his right, as they start to climb the stairs. Then the life belt flips back to the way it was originally.
Visible crew/equipment: After Roy and Johnny have listened to Brackett's tape of 110's rescue, when they get to the squad the outline of the lavalier mic transmitter is visible on the back, right side of Johnny's shirt, as he stores some things in the squad.
Revealing mistake: After Brackett has played the tape of 110's rescue for Roy and Johnny, when they get into the squad, the usually highly reflective chrome surface of the driver's side spotlight has been sprayed with a 'dulling spray', to temporarily dull the finish for this shot.
Visible crew/equipment: After Roy and Johnny give a CPR demonstration at the ladies' club, when one of the women thanks the paramedics, the outline of the lav mic transmitter is visible on the back of Roy's shirt.
Continuity mistake: After Johnny has gotten Sheba off the roof, he and Roy stand by ladder as Sheba takes off after the cat again, and in the shot of the dog running across the roof Roy and Johnny are gone - the ladder stands alone, but in the next shot the paramedics are by the ladder again. Also note that the door behind the ladder is alternately closed or open, depending on the shot.
Visible crew/equipment: When Johnny climbs the ladder and then picks up Sheba to carry her off the roof, the outline of the mic transmitter is visible on the back of his shirt. Additionally, as he's lifting Sheba the big dog pushes up against the front of Johnny's shirt, and we hear the crackling noises that were picked up on Johnny's hidden mic.
Continuity mistake: When Roy and John are in the apparatus bay talking about Joanne, just after Roy walks away, Boot steals the armboard splint package with the writing facing up in his mouth, but when Boot hides under the squad the reverse side is up in his mouth.
Continuity mistake: When Johnny and Roy have to go in search of the two boys lost in the storm drain, the air cylinder that Johnny grabs from the squad has two large red stickers, but when Roy and Johnny climb down below, Johnny's air cylinder has changed - both of their tanks now have the large arrow stickers.
Visible crew/equipment: In the waiting room, when Dixie brings the couple with the sick little boy (lead poisoning) to the admitting desk, we can see the small tape mark on the floor behind them, where they had just been standing.
Dinner Date - S2-E10
Revealing mistake: In episode 2x5, "Peace Pipe", when Brackett gets on the line with Johnny, who's at the scene of the drunk driver's accident, Brackett presses two buttons - the third and fifth, to record the conversation on the tape machine. However, in this episode when Dixie gets on the line with Johnny, while he's with the little girl whose arm is stuck in the pool drain, Dixie presses only one button - the second, to record the conversation.
Dinner Date - S2-E10
Continuity mistake: When Johnny and Roy are standing by the squad outside Rampart, talking about the man in a hepatic coma, both ER doors are wide open, but when the woman drives up and then shouts that she needs help both doors are closed, and this continues a few times depending on the angle of the shot.
Audio problem: After helping the guy who was trapped in his sofa bed, Christy, Roy, and Johnny get back into the squad, and then we hear Johnny tell the dispatcher that Squad 51 is returning to quarters, but we see that Johnny's not actually saying anything.
Continuity mistake: When Ed chases after the possible OD into the car wash, Roy sits at the passenger side of Squad 51 to contact dispatch about the sheriff's ETA, but each time it cuts to the car wash employee the squad is empty behind him, even though Roy is still there in his closeups.
Continuity mistake: When Roy and Johnny are rescuing the elderly man from the burning house, in the interior shot Roy exits the window by placing his left leg out the window onto the ladder, but when it cuts to the exterior shot Roy has his right leg out the window on the ladder.
Peace Pipe - S2-E5
Continuity mistake: Before Roy and Johnny climb up to the injured man (who was shot) lying on the scaffolding, they put on their life belts (pompier) with the tongue buckles and carabiner hooks towards their right sides, but both stuntmen wear their belts the opposite way. Also note the axe sheaths (attached to the pompier belts) are upside down on Roy and Johnny, but right-side up on the stuntmen.
Peace Pipe - S2-E5
Continuity mistake: When Squad 51 is dispatched to the woman who's having difficulty breathing, the address is given as "1017 Crocker", but when they pull up to the building's corner the street sign reads Colfax.
