Other mistake: Station 51 responds to an "accident with injuries, " address 7526 Sunset, cross street, Abbott, to rescue two people stuck on scaffolding at the top of the tall building. This distinctive, mirrored glass building was also used this season in episode 6, "Rules of Order", with the address given as 3120 South Century, cross street, Burgess, for the rescue of two people hanging off the side of the tall structure. The actual building address is 500 190th Street, Gardena, CA.
Continuity mistake: When the firemen cover the tanker in foam, the paramedics and ambulance drivers extract the tanker driver and place the patient on the stretcher they all get covered in foam, including the stretcher. Next shot, the stretcher, the patient and the men are all clean.Super Grover
Continuity mistake: Frequently during the first two seasons there will be long shots of Squad 51 running down the road but it has mysteriously become a mid-60's Dodge (easily visible because of the red painted grille) instead of the familiar 1972+ model Dodge with a chrome grille. It also has 51 on the door which makes for a significant paradox.
Continuity mistake: Just before Engine 51 and Squad 51 arrive at the scene of the hang gliding incident, there's a long shot of the victims lying injured on the side of the cliff, and when the camera zooms out we see Johnny and Roy with the informant of the accident standing at the top of the cliff, even though Squad 51 hasn't actually arrived at the scene yet. That same shot is shown a minute later after they all arrive, when Roy says that he'll get some equipment.Super Grover
Continuity mistake: While Johnny and the doctor are in the pressurized chamber with the diver, the guy outside the chamber tells them that they're at 165 and vetting, as he holds the mic up to his mouth with his left hand, but when it cuts to the interior shot, the mic is held up in his right hand.Super Grover
Continuity mistake: When dispatch drops the tones at night, waking all the guys up, notice that Marco's mustache has vanished, though it reappears later. Additionally, they all get into their boots, turnout trousers, only white T-shirts, suspenders, and grab their dark jackets, but when the bay door opens they're dressed in their uniforms as they respond. Then at the fire they're in the turnout trousers, and Johnny and Roy are wearing the uniform shirts when working on the burn victim.Super Grover
Other mistake: When Squad 10 is dispatched to the the high-voltage electrocution, Tony opens the bay door, but the closeup we see is actually the same closeup of the hand cupping the switchplate that was shown earlier, when dispatched to the nighttime factory fire.Super Grover
