bnemirowNo Such Thing as Bad Luck - S7-E18
Character mistake: At the formal awards ceremony for Cruz the Police officers and Cruz are in dress uniform with their covers on. Serveride joins them on stage in uniform without his cover on and salutes Cruz. Serveride should have known to have on his cover for the ceremony. (00:58:00)
Snag.1Factual error: In the scene at O'Hara airport the paramedics meetup with a TSA officer. The TSA officer has a gun as a part of his uniform. TSA officers do not carry firearms. In addition, the CBP officer in the scene does not have on a proper CBP uniform. The CBP officer uniform has rank epaulets and officer has no epaulets, and the CBP uniform doesn't have a bar tie clip and the gun belt buckle is brass not stainless metal. (00:42:00)
Snag.1Continuity mistake: Chief Boden is in his dress uniform and his award ribbons above his right pocket are hanging down. There is an emergency and he orders the firefighters to mount up to depart the firehouse. They all leave in a hurry, and when Chief Boden arrives on the scene his ribbons are no longer hanging from his jacket, but intact and straight above his right pocket. (00:41:00 - 00:43:00)
Snag.1Continuity mistake: Casey and Kelly are on the roof smoking cigars when a man runs up carrying his daughter yelling for help. Both Casey and Kelly put down their cigars and are next seen sliding down a ladder with black gloves on. They were not smoking cigars wearing gloves, and wouldn't have time to put them on to get off the roof as fast as they did. (00:21:00)
Snag.1Continuity mistake: When Brett and Dawson go rescue the two climbers, at the very beginning you can see a long shot of the group where the victim is lying with her legs and arms straight, while in the rest of the scene she lies there haphazardly in consequence of the fall. (00:09:45)
balistenerContinuity mistake: When Dawson and the police detective are knocking the door of a suspect a neighbor is coming out to sidewalk and the snow is piled high along the sidewalk and parked cars.

Snag.1Continuity mistake: At the hospital, when Cruz talks to Herrmann while he still has the oxygen mask on, Herrmann's hand keeps switching between clutching the mask on his face and resting at his side. (00:38:45)
balistenerApologies Are Dangerous - S3-E4
Continuity mistake: When driving to their first call that shift (guy stuck between cars), Truck 81 is seen arriving at the scene while it should be still being repaired. When they arrive back at the firehouse, the truck they drive carries the number of the exchange truck they've got (E-..).
Continuity mistake: Brett enters the abandoned factory twice when she is searching for the missing girl.
bnemirowContinuity mistake: No snow in all exterior scenes except for when Chief Bowden pays a return visit to have dinner with the female resident of the building which was a fire scene early in the episode. He gets out of his car and walks to the building with several inches of snow on the ground. The immediate next scene of Shay (supposedly the same time) has spotlessly clean streets.
bnemirowOther mistake: In the pilot, Heather Darden states that Andy had been at the house for 14 years. Assuming that he was placed there directly after the Academy that would place his age at 32 years old at the time of his death (2012). In Season 3 (I Am the Apocalypse), April Sexton gives her year of birth as 1982, making her 33 years old in 2015. April and Andy both are said to be the same age as Kelly Severide, as Darden went to kindergarten with him and April sat next to them in class, however there is at least a 3 year age difference between Andy and April.
