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.
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.
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.
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.
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.
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

Peace Pipe - S2-E5
Continuity mistake: When Roy and Johnny decide the only choice is to break the glass on the gumball machine, Roy holds the green bottle of soap, but they're both empty handed when they walk back to the squad. When Johnny hands Roy the gloves and the 5-hole hydrant wrench, then start to walk back to the boy, in the next shot the green bottle of soap has suddenly reappeared in Roy's arms.
Peace Pipe - S2-E5
Continuity mistake: When Vince finds the liquor bottle in the drunk driver's car, he says that the driver has a cut, but doesn't think he feels it, and in the next overhead shot we see Johnny and Roy (at the left of the screen) walking away from the car with the drunk driver between them. However, in the next shot the drunk is still in the car, then in the next shot we see them at the front corner of Engine 51 in the background, but then he's back in the car again.
Continuity mistake: During the rescue at the movie studio, when Roy and Johnny wrap the line around the stuntman's waist, Johnny's belt does not go through his pants' back center loop, but a moment later after the wagon falls, when they pull the stuntman up, Johnny's belt now goes through that back loop.
Continuity mistake: When Roy, Johnny, and Chet are cleaning the locker room/bathroom while talking about the models' upcoming visit, dispatch drops tones for 'man trapped in a ditch', and then we see Johnny and Roy coming from the kitchen which is on the opposite side of the firehouse.
Continuity mistake: When Johnny and Roy are with the boy whose head is trapped in the window under the porch, the guys use the Porta-Power to lift the top jamb. When the child gets his head out and his mom tells him to come out from under the porch, the top jamb is straight and level, but when the boy walks away with his mom, the top jamb has lifted itself again.
Continuity mistake: During the structure fire, when Roy walks into the burning house his SCBA cylinder has a large arrow sticker on it, but when he's in the house searching for the boy it's a completely different tank with two red stickers, then when Roy goes upstairs it's back to the original tank.
Continuity mistake: When Roy tells the other guys of 51 what they need to do to rescue the doctor, once they're in the hot room, in the wide shot Roy's holding the handie-talkie in his right hand as he's gesturing with that hand, but when it cuts to Roy's closeup the HT has vanished from his right hand, as he's still gesturing.
Continuity mistake: After John makes a sarcastic comment, while he and Roy are in the treatment room with Dr. Early, Roy takes the squad's oxygen tank with him when he leaves the room, but when he exits the ER to get into the squad, the oxygen tank is gone.
Continuity mistake: When Johnny and Roy go into the radioactive lab, Johnny removes his glove to check the doctor's carotid pulse and when they walk through the doorway both his gloves are off (he's holding them), but in the next shot exiting the doorway both of Johnny's gloves are back on.
