Other mistake: When the dispatcher drops tones for the structure fire, he calls on Station 51, Engine 27, Engine 32, and Truck 105. Once there, Captain Stanley tells the dispatcher to send a second alarm, then hear him call on Station 19, Truck 98, Truck 34, and Battalion 43. However, the only ones at the fire with 51 are Engine 9, Engine 17, Truck 17, and two men with helmets from 20, even though dispatch did not call on any of them, and of all the companies that were called to the fire, none were there, except for 51.
Other mistake: On the first run of the Ward LaFrance we hear the dispatcher say, "Wrecking yard fire," but subtitles read, "Working yard fire," and as soon as Engine 51 rolls up on scene Mike turns to Captain Stanley and asks, "Light water?" but subtitles read, "Do we got water?" Then we hear the dispatcher say, "Repair 3, call Station 8," but subtitles read "Return 3..." Subtitles from Universal Studios 2010 DVD.
Other mistake: On scene at the plane crash, just as Roy and John are about to head down to the aircraft we hear the dispatcher ask, "Foam 23, what is your location?" but the odd subtitles read, "Phone 23..." Subtitles from Universal Studios 2010 DVD.
How Green Was My Thumb? - S3-E17
Other mistake: Eric Shea appears in "The Hard Hours" as Clyde, the boy who built a full size rocket, but he's mistakenly listed in the credits at the end of this episode.
How Green Was My Thumb? - S3-E17
Other mistake: During the refinery fire, while Roy is with Fernando the first victim, we hear Roy say, "It's OK, you're gonna be all right," but the subtitles read that Johnny says that. Subtitles from Universal Studios 2010 DVD.
Other mistake: At The Boat explosion incident, when Roy and Johnny climb aboard The Boat Johnny says, "We'll set up the Biophone here," but subtitles read "We'll set up the platform here." Subtitles from Universal Studios 2010 DVD.
Other mistake: When they're trying to identify the address of the attempted suicide, Engine 51 stops and is standing by at 223 Street and Ridgely, while the squad drives elsewhere, and when Squad 51 stops it's standing by at 218 Street and Carson. However, when they're dispatched we see that the rigs are actually pulling away from the same corner but facing opposite directions, note the area and background. Then when Johnny and Roy put on their turnouts, in the next shot of Engine 51 it's now driving towards the camera in the opposite direction on the same street they had pulled away from.
Other mistake: When the squad and engine roll up on the scene of the bulldozer accident in the junkyard, just as the guy runs up to inform them about the victims, have a look at Squad 51's license plate number because it is not the normal prop plate number E999007.
Other mistake: Just as Squad 51 reaches the Tank Motorway, in the shot of the squad as it drives towards the camera before it zooms out, look at the squad's license plate before it stops. Even through the haze, we can see that the plate number is not Squad 51's normal E999007.
Other mistake: When Roy and John are examining the boy who jumped from the ledge, they're standing at the back of Engine 85 while the boy's sitting on the tailboard, and we can see behind his head the vinyl material with the imprinted 85, covering the attached plate with the real company number.
Other mistake: During the fire at Hammond Chemical, when Engine 7 rolls up and lays duals, we can see the vinyl material adhered to the top of the cab covering the engine company's real number.
Other mistake: During the paint factory fire, when Engine 2 rolls up, we can see the red, large, rectangular vinyl material that is adhered to the front of the engine, with the company number printed on it. There's also vinyl material adhered to the top of the cab as well as the back of the engine with nothing on it, presumably covering the engine company's real number.
Other mistake: When Squad 51 is dispatched to the possible heart attack, while Chet’s at the base station responding to the dispatcher, the lightbar atop Squad 51 has nothing covering the chrome, but en route in the close up there's black tape covering much of the chrome trim.
The Promise - S3-E11
Other mistake: At the very end, when Roy is cleaning the windshield while John's fiddling with the squad’s radio mic, the spray can on the hood of the squad has tape covering the brand name.
Other mistake: When Dixie's on the phone with the suicide attempt, Dixie tells her the date of her own birthday, hoping to get the caller's birthday in return. Then when the caller tells Dixie that the month of her birth is February, while Brackett's listening, they don't contact Early who's with the senior data analyst with that crucial information to help narrow down her identity faster, which was the whole point of Dixie trying to get that information from her.
Other mistake: During the fire at the horse ranch, when Engine 40 rolls up we can see that the engine company's number is covered atop the cab, and the large, red rectangular vinyl material that's adhered to the back of the engine with nothing on it. Presumably covering the real engine company's number.
How Green Was My Thumb? - S3-E17
Other mistake: When Station 51 is dispatched to the fire at the winery, just as Squad 51 rolls up, in this semi-closeup we can see that it's Roy driving and exiting the squad, and also that it's actually Randolph Mantooth's double exiting the squad and getting the drug box from the side compartment. Also fun to note the difficulty the double had just opening the squad's door.
Heavyweight - S3-E5
Other mistake: When Chet is preparing the lasagna, then tells Johnny that he's preparing 'rutabaga delight' especially for him, the green container of parmesan cheese has tape covering the brand name, though it looks like it's the Kraft brand.
Inventions - S3-E22
Other mistake: When Station 51 responds to the incident of the man who fell through the ceiling at his mother's house, the footage of the squad and engine pulling up to the curb of the house is from episode 3x15, "Messin Around", when they rescue Old Bill after he's collapsed in his house.
Other mistake: After Johnny gets hit by the phantom in the apparatus bay, Station 51 is dispatched to an unknown type rescue at 617-1/2 Kimball Rd, and before the dispatcher even gives the address, Mike has already located the area on the map with his finger.
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
