Daisy's Pick Blind Date - S4-E7
Continuity mistake: While Roy, Johnny, and Cap are in the ice house with the hypothermic victim, there's a closeup of the pipe's frozen shut-off valve in the upright position with an ammonia leak, and the manifold temp/pressure gauges that are hanging from it. Then, when Johnny goes to wrap the rag around the valve it's upside-down, but in the next shot the valve is upright once again, and the manifold gauges are now facing the opposite way.
Daisy's Pick Blind Date - S4-E7
Visible crew/equipment: After the hypothermic victim is rescued from the ice house, just as the attendants wheel the stretcher into the ER, at the end of the hallway, the top of the set is visible where the ceiling should be.
Visible crew/equipment: While Roy is hanging off the side of the building with the second victim, Johnny's trying to tie off the swaying sign, then after he asks for some slack the second time, there's an overhead shot from the roof, and we can see the shadow of the camera and a bit of a crew member, at the bottom of the screen. Then a few shots later, from the same POV, we still see the camera's shadow, and we also see the leg of a crew member (white sneaker and dark pants) walk into the shot and back out, at the left of the screen.
Continuity mistake: When 51's guys get to the roof of the building with the swaying sign, Marco places the silver hose roller on the roof edge, but when Captain Stanley and Stevie's father lean over the edge to talk to Stevie, the second larger hose roller is already in place near the silver hose roller, even though the second one hasn't been brought to the roof yet by Engine 95's guys.
Continuity mistake: At the park, when the attendants load the mugger into the ambulance, and also when the ambulance backs up to Rampart's ER receiving, just as Squad 51 turns and starts backing up, the type of ambulance that parked is a station wagon, but in the next shot while Squad 51 is still backing up, that ambulance has suddenly become the truck type.
Heavyweight - S3-E5
Character mistake: When Johnny first contacts Rampart via landline about the stabbing victim, while Roy is across the street with the gunshot victim, Brackett gets on the line and asks Johnny if he started an IV, to which Johnny replies no, then he asks what the vitals are. Johnny has only just made contact with Brackett about this patient, so Johnny could not have started an IV without the doctor's consent, Brackett knows this. This goes against established procedure.
Heavyweight - S3-E5
Visible crew/equipment: When Roy and Johnny are with the man who was injured by a gunshot, Johnny goes across the street to treat the stabbing victim, and just as Johnny and the others enter the living room, the shadow of the moving boom is visible on the wall to the right.
Continuity mistake: Just after Brackett tells Early that the patient he was talking to is his father, it cuts to a shot of Squad 51 pulling up the driveway, and the Engine 51 we see parked in the apparatus bay is not the current Ward LaFrance pumper, it's the original Crown engine from seasons 1 and 2.
It's How You Play the Game - S4-E19

Visible crew/equipment: When Johnny and Roy are at the top of the open drawbridge, beside the car hanging over the edge, just after Roy says "Be careful, this could go at any minute," the moving shadows of the cameraman and another crew member are visible on the bridge surface. That shadow is visible in two other previous shots from the same angle.

Visible crew/equipment: After the fake eye exam 51's guys are sitting around the kitchen table, and when Chet tells them that he was sitting in the front row at the movies, there are moving shadows at the bottom, right corner of the screen, which do not belong to the guys.
Continuity mistake: When 51's guys are at the table eating and discussing Roy and Johnny's deal, Johnny tosses his car keys to Roy, and in the following shots those keys vanish and reappear on the table repeatedly, and in the shots where the keys appear on the table, it's the ketchup, mustard, and napkins that have vanished. Also notice that the ketchup's brand name is covered.
Deliberate mistake: When O'Brien shows up at the nurses' station for Dixie's answer, after she declines the offer Dixie walks off to a patient who's brought in by the police, and the last closeup that's shown of O'Brien is flipped - note his hair is parted the opposite way and the background is backwards.
