Visible crew/equipment: When Roy and Johnny find the two puncture marks, from the snakebite, on the unconscious man's leg, the outlines of the lav mic transmitter and wire are visible on the back, left side of Johnny's shirt. It's also visible on the back of Roy's shirt after he is hit with the cobra venom, and on the back of Gil's shirt when he brings in the defibrillator.
Visible crew/equipment: After Johnny and Roy arrive at the amusement park where the boy was injured on the go-kart, when the guy who runs the go-kart track walks over to Roy and Johnny, the outline of the mic transmitter is visible on the back of his shirt, and moments later it's also visible on the left side of Johnny's shirt. Also, when the guys scare the second boy with the huge needle, as he runs away the outline of the mic transmitter is visible on the back of the boy's vest.

Visible crew/equipment: When Brackett walks into the adjoining treatment room to talk to Pete about his pregnant wife, and tells him to sit, the legs (wearing jeans) of the cameraman/crew member are reflected on the chrome of the gurney, as he walks forward when the camera dollies in for a closeup.
Visible crew/equipment: At the home of the pregnant woman who was shot, the only ones there with Dora are Pete, Roy, Johnny and Vince. When the two ambulance attendants bring in the stretcher, a crew member's entire right arm (wearing short, white sleeve with pinstripes) comes into view on the right side of the screen, as the camera pans back.
Visible crew/equipment: When Art, The Screenwriter, goes on his first ride-along with Squad 51, just as Art rambles on about the fire truck on its mission of mercy going 80 miles an hour, two shadows of mic/camera equipment are visible on the left and right side of Squad 51's hood. What's amusing is that a moment prior to this, Art actually says that they could mount a camera right on the hood of the truck, when they make the film about paramedics.
Visible crew/equipment: When the Animal Control guy and the officer are in the grocery store, a few shots after the tiger jumps over the counter, the hand of a crew member (presumably the tiger's trainer) is visible behind the boxes holding a piece of food, as the tiger walks toward it (away from the camera).
Continuity mistake: After Johnny and the attendants exit the ambulance with Dora, the pregnant woman, the ambulance is empty and the drug box is on the seat with the Biophone on the floor beside the seat, but in the next shot as the gurney is wheeled inside, the drug box is now on the floor between the Biophone and seat.
Other mistake: After Roy and Johnny leave Wild Bill's apartment because he faked his injury, there's an overhead exterior shot of what is supposed to be Rampart, but it's not actually Rampart. Throughout the entire run of this series there are numerous exterior shots of Rampart from every angle.
Character mistake: After Squad 51 joins Engine 51 at the heart attack incident, while Roy's on the Biophone with Rampart he sends a second EKG strip, and Early orders, "100 milligrams lidocaine bolus," but he mispronounces lidocaine and says, "Lidograin," then he pronounces "Lidocaine drip" properly.
