Continuity mistake: After being dispatched to "industrial accident at railroad yard," once they rescue the man from the train car carrying trichlorethylene, when Roy and John are standing beside Engine 51 we can see the empty red disc on the side of the engine covering the real engine company number (127), as well as the American flag sticker on the windshield. Earlier, when they were dispatched, there's no disc or sticker in the closeup of Engine 51 (played by Engine 60).
Continuity mistake: When the guys are listening to the baseball game on the radio, dispatch drops tones for Engine 16 and only Squad 51, yet Chet turns the radio off, and all the engine company guys rush out of the day room then head to their rig, even though it's only Roy and John that were dispatched.

Continuity mistake: After Johnny and Roy find the motorcycle and its injured rider, Johnny wraps his arm/shoulder area, but the way it's wrapped - whether or not it's over the shoulder and/or at his waist, and the amount that's wound around his body, significantly differs between shots until they see Vince at the base station.
The Wedsworth-Townsend Act - S1-E1
Continuity mistake: When the man who was electrocuted is loaded onto 127's snorkel, we can see that he's wearing a white crew-neck undershirt under the denim shirt, but at the ER when his denim shirt is open there's nothing underneath.
Continuity mistake: When the man who doesn't speak English is in treatment 4, there's a closeup of the Datascope 850 monitor, and then the girl points to the EKG monitoring unit behind the gurney and asks Dixie why the thing is bouncing up and down. Problem is that the Datascope 850 is used by the paramedics and it's not actually in that treatment room. The treatment room has a Zenith Travenol unit.
Continuity mistake: When Squad 51 is dispatched to the attempted suicide, the dispatcher states that he's in apartment 2A, and when Roy and John arrive at the scene the police officer also says he's in apartment 2A, but when they get to the second floor they pass apt 2A and go to the apartment at the end of the hall.
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 cutting the shaft where the burglar is trapped, in the close-up of Johnny taking the K-12 from Roy we can see the ladder that Roy's standing on, and when it cuts back to Roy after Cap's closeup, the ladder Roy's standing on has switched around to the opposite way.
Continuity mistake: While John's lying in the lateral tunnel when digging to reach Helena, his entire uniform is covered in dirt, but when John pulls her out and is with Roy in the rescue shaft, John's uniform is only a little dirty, nowhere near as filthy as it was just moments before.
Nurse's Wild - S1-E7

Continuity mistake: At the airport, when Roy is being told about young Frankie flying the airplane because his father had a heart attack, we see that Roy's wearing his uniform shoes, but in the shot of Roy following the airport employee while they're running into the building, Roy (perhaps his double) is wearing tan work boots. The uniform shoes are back when Roy uses the grounded plane's radio mic.
