Other mistake: After Station 51 responds to the 'man caught in an air conditioning duct', when they get on the elevator its metal sliding doors and metal jamb on the lower lobby have scratches and dents on the exterior, and the same scratches and dents are on the doors and jamb, when they reach the upper level.
Other mistake: When 51's guys are watching an Adam-12 episode on TV (in Emergency!'s pilot, Reed and Malloy are real), on that show just after Reed is knocked out, the hitman says "Nate would've blown his stack if I'd let you go," (refers to hitman's partner, Nate), but Emergency!'s DVD subtitles read, "Pete would've blown his stack," (Pete Malloy is Jim Reed's partner). Moments later hitman Nate yells, "I wanna talk a deal," but subtitles read, "I wanna talk to Neil," and there isn't even anyone named Neil.
Other mistake: After being dispatched to the heart attack, when John and Roy have cardioverted the V-fib Brackett asks for another EKG strip, and when Brackett lifts the chart paper to read it, it just shows flatlining, no rhythm whatsoever.
Other mistake: There are two specific pieces of stock footage used from season 3 onward, when the camera faces the fire station, it shows either just Squad 51, or both Squad 51 and Engine 51 pulling out of the apparatus bay, then turning left (viewer's right) onto E 223rd St, and the real Station 127's Truck 127 can be seen parked in the side driveway. Examples are: In season 6, "The Exam", when Squad 51 responds to Molly's phone call, and in "Hypochondri-Cap", when Station 51 is dispatched to an 'unconscious female in a car'.
Pressure 165 - S5-E7
Deliberate mistake: When Roy and Johnny are on the Coast Guard helicopter, approaching Catalina Island with the injured diver, there is a closeup shot of them looking out the windows, which is a flipped shot - note the backwards paramedic patch on the right sleeve, instead of being on the left sleeve.
Other mistake: After Station 51 arrives at the structure fire, Captain Stanley tells Mike to get water to their lines (charging the two lines) and then mule the supply line back to the hydrant. When Marco and Chet get the two lines, they head to the house with Captain Stanley and start hosing the fire down with charged lines. A few shots later, we see Mike going to the back of Engine 51, and the two lines that Chet, Marco, and Cap have been using are flat and not even charged yet.
Visible crew/equipment: When Roy, Johnny, and Karen are waiting outside the treatment room with the elderly patient, with Brackett and then with Dix, the outlines of the lavalier mic transmitters are visible on the left sides of Roy's and Johnny's shirts, over their belts.
Character mistake: After the cat has her kittens, when Squad 51 is dispatched to the 'man trapped in boating accident', we hear Captain Stanley respond, "Station 51, KMG365," even though his response should have been, "Squad 51, KMG365," since it's only John and Roy that were dispatched, not the entire station.
Continuity mistake: While Squad 51 is out on the run (quite literally) with the female OD, Johnny gets a cut on his elbow which he keeps fidgeting with even after it's bandaged. When Roy and Johnny get back to the station and see The Old Engine, Johnny's cut has vanished.
Continuity mistake: After the Bengal tiger jumps on Les, the feline walks up the aisle that is directly in front of the self-serve ice cream freezer, and knocks over the pyramid of Hi-C cans that block the aisle, but a few shots later the tiger walks up that same aisle (note the ice cream freezer), and the mess of Hi-C cans have vanished.
Continuity mistake: After Johnny sees the Bengal tiger in the market, he backs away, and when Johnny is about to walk through the curtain, in the shot from the back room we see the tall shelving display of chip bags on the other side. However, in the next shot from the store that display of bags is gone, there's only a display of loaves of bread in front of the fruits and vegetables.
Deliberate mistake: At the market, after the tiger knocks over the pyramid of Hi-C cans, which were set up blocking the aisle just for that purpose, the officer tells Les, "Down that aisle," and the next shot of the aisle is a flipped shot - note the backwards words on the upside-down boxes. Two shots later that same aisle is shown properly, not flipped.
Continuity mistake: After Roy and Johnny's pre-dawn rescue at the market, by the time Roy advises dispatch about the tiger and when Animal Control shows up at the market, it's already past sunrise, but when Les and the officer walk into the store and then when they follow the tiger up onto the roof, it's nighttime again.
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: When the dispatcher sends Squad 51 to the heart attack at the bank robbery location, the address is given as "2057 North Hillcrest, cross street Barker," but when they arrive at the corner bank, the sign reads Celis Street.
Continuity mistake: When Johnny and Roy are on the "child locked in a bathroom" run, Johnny makes a hasty retreat leaving Roy to deal with the "child." The bar of soap Roy uses is on a curved pedestal soap dish, and that dish is either curved towards the wall, or turned the opposite way, depending on the camera angle.
Propinquity - S3-E20
Other mistake: When Station 51 is dispatched to the traffic accident, while en route first we see Engine 51 with nobody on the back, but then we see two firemen standing at the back, and they are Johnny and Roy. This footage is from the episode "The Old Engine" in season 3, when Station 51 got the new Ward La France engine, and since the previous shift was still out with the squad, Cap told Roy and Johnny to jump on the back and join them on their first run with the new engine.
Inventions - S3-E22
Other mistake: After Johnny and Roy are seen carrying the semi-conscious worker during the chemical leak, Captain Stanley tells Mike to get the life gun, and tells Chet to secure a lifeline, then before he mentions getting the guys from the catwalk via the lifeline, we hear Captain Stanley tell the Battalion Chief (into his handie-talkie), "Battalion 14, Engine 41," even though he's Engine 51, not 41. Additionally, when Cap tells Chet about the lifeline, two firemen behind Chet are wearing helmets with no company numbers on them.
