Daisy's Pick Blind Date - S4-E7
Other mistake: When dispatched to the fire in the theater, the companies called are Station 51, Engine 85, and Station 36, but at the scene of the fire we see Engine 9 roll up and also see firemen with 19 on their helmets. These are shots from previous episodes including 3x7, "Promotion", when Roy and John rescue the security guard at the structure fire.
Other mistake: After Station 51 is dispatched to the 'vehicle accident with injuries', in the exterior shot as the squad and engine roll out, we can see the real Station 127's vehicle is still parked inside the apparatus bay, near the rear bay door.
Other mistake: When Station 51 is at the scene with the electrocuted man, he's dangling from a rope below the second stem of the letter H, in the large sign which reads "HOTEL", above the striped awning. In the shots from above the sign, looking directly down as they set up the ladder, we can see the letter H and the awning, but the dangling man is simply not there in the shots from this perspective, even though we should be able to see him.
Other mistake: At 6:50 AM, just before the dispatcher transmits the testing tones to Station 51 which wakes everyone up, we're shown the exterior shot of the station and the two flags are already flying. Guys of C shift (as Chet states) haven't arrived yet that morning, so they didn't raise the flags, and we know it's Mike who always raises the flags on A shift, but he only just woke up when the dispatcher sent the tones.
Other mistake: When Station 51 is dispatched to the structure fire, the address is given as 1127 West Winston, but when they're on the scene, the fire flashes through the front door causing Marco and Chet to fall back, and the house number on the stairs is 1026.

Other mistake: When Johnny and Roy are in the ice house, there's a closeup of Johnny's arms as he's hosing down the ice and removing it from the hypothermic victim's arm, but it's obvious that the dark hairy arms belong to the stunt double, not to Johnny.
Camera Bug - S4-E10
Other mistake: At the end of the episode, when Johnny's telling the other guys that his photograph was bought, the box of cereal and carton of milk that are on the table have tape affixed to them, to deliberately cover their brand names.
Other mistake: When Squad 51 is dispatched to the liquor store shooting, en route they are almost hit by a driver who passed a stop sign at the intersection. This is the same footage from season 2, episode 13 "Drivers", when the squad is almost hit by a car while responding to a football injury.
Other mistake: When Engine 51 pulls up to the hotel with the injured man dangling from the hotel sign, Captain Stanley addresses Chet and says, "Chet, Roy and John'll need a line," but the subtitles read, "See that? Roy and Dan'll need a line, " even though there isn't anyone named Dan. Subtitles from Universal Studios 2010 DVD.
Other mistake: When the tones drop and Station 51 is dispatched to a "man injured", there is a closeup of the guys running from the kitchen into the apparatus bay, heading for the squad and engine, and none of them are actually 51's guys.
Other mistake: During the fire at the chemical plant, when Captain Stanley and Roy find the missing man and carry him out, the subtitles read that Johnny says "All right, grab his feet," when in fact it's Captain Stanley who says that - Johnny's not even in the same room with them. Subtitles from Universal Studios 2010 DVD.
Other mistake: At the scene of the vehicle accident, with a raging fire going on, the Chief communicates over the HT with Copter 10, and when Copter 10 arrives and makes the water drop, it is actually Copter 14 we see in all the shots.
Other mistake: When John, Roy, and Vince grab the officer who was shot by the sniper and make a run for it, as they duck behind the car, right behind them we can see a city bus just driving on by the lot, directly in the sniper's line of fire, even though that area's supposedly closed off with heavy police presence.
