Continuity mistake: When Roy and Johnny are at the construction site with the guy who wants to jump, before Roy walks over to him we see the pompier belt around Johnny's waist has the carabiner hook to his left and the double tongue buckles to his right. Then when Captain Stanley tells Johnny to try and get to the guy from the other side, Johnny's belt is now around his waist the opposite way. In the following shots his life belt flips around a couple more times. Note that their pompier belts have at one side double leather straps which are the two tongue buckles, and the other side has a single strap of leather for the attached carabiner hook.
Continuity mistake: When Squad 51 and then Engine 51 are dispatched to the hotel fire, before going in Johnny's SCBA cylinder has a large arrow sticker and Roy's has a large red sticker, but once inside Roy's air cylinder goes back and forth from having an arrow sticker to the red sticker. Then in a few moments, when Marco and Chet go in with the stokes, both of their air cylinders are tall, flat-top and devoid of stickers, but inside their SCBA cylinders are short, round-top and keep switching from having either an arrow or large red stickers.

Peace Pipe - S2-E5
Continuity mistake: Treatment 4 is beside the nurses' station, as seen when Roy and John are with Debbie's parents, while the drunk driver is being wheeled through the double doors. Later, when Brackett suspects that Debbie's father is with the drunk, as he rushes to the drunk's room he goes through the double doors to get to the room, but while Brackett's in the room speaking to Debbie's father we can see treatment 4's door right behind Brackett, even though they're supposed to be in a completely different area.

Continuity mistake: When the guys of Station 51 are dealing with the rescue of the doctor from the radioactive lab, Johnny's, Chet's, and Marco's SCBA cylinders change during this scene while they're all wearing them. Differences such as tall, slim, with a flat top vs short, wide, with a rounded top, and also the writing on the tanks. Marco's even changes between shots, when he exits the lab's doorway.
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 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.
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.
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.
Smoke Eater - S4-E16

Continuity mistake: When Johnny starts chasing Harriet down the street, in Johnny's closeup when he passes the white house (right after the yellow house), there is a light colored wagon-style car parked in the driveway, but in shots from other angles there is a green 2-door parked in that driveway.

When Roy smears mustard on his bun, Chet motions for the mustard with his eyes and Roy slides it over to him to use, but in the next few shots the open jar of mustard is either in front of Roy or Chet, depending on the angle of the shot. The milk container keeps switching places as well.
