Other mistake: When the dispatcher calls for Squad 51 about an unknown rescue, Roy almost closes the squad's hood on Johnny's head, and when Captain Stanley responds the usual KMG365 with the hand mic, we can see that the mic's cord is dangling down, not even plugged into the base.
Continuity mistake: While Charlie is finishing up on the squad's engine, Captain Stanley hands Johnny the address in the canyon that has overgrown weeds, and when Johnny packs up the toolbox, Charlie holds out the roll of electrical tape and the combination wrench, with its open-end up. However, in the next shot the only thing Charlie holds out is the wrench, but with its box-end up.
Visible crew/equipment: While Johnny and Gage are in the press box with the cardiac arrest, when Brackett tells Johnny to administer the bicarb and epinephrine, the bulging outline of the mic transmitter is visible on the left side of Johnny's shirt.
Visible crew/equipment: When Roy and Johnny are stuck in the elevator with the cardiac patient, the outline of the lav mic transmitter is visible on the front, left side of Roy's shirt, above his belt.
Visible crew/equipment: When the boy who was shot by a pellet gun is wheeled into the treatment room, at the start of the next shot there is a closeup of the domed surgical light fixture, which provides a reflection of crew and equipment, albeit upside-down.
Visible crew/equipment: When the injured father and daughter are wheeled into the treatment room, an actor's tape mark is visible on the floor under the daughter's gurney, and another tape mark is visible on the floor under the father's gurney.
Visible crew/equipment: At Rampart, when Gage and DeSoto walk into the staff lounge, where Dixie and Dr. Brackett are seated at the table, there is an actor's T-mark on the floor behind Dixie, where DeSoto stands.
Visible crew/equipment: When Roy is in the ER due to the dizziness, two actors' T-marks are visible on the floor near the door, where moments later Dr. Bracket and Dr. Early stand before leaving. Additionally, Dr. Early's mark (during The Exam) becomes visible when Dixie shifts her position, just as Dr. Bracket asks, "Any pain here, Roy?"
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: When Frankie lands the Cessna, the red seatbelt is in place behind him. When Gage and DeSoto reach the plane that seatbelt has been pulled across the side wall, over the door, with its end pushed between the windshield and ceiling. Done deliberately so Gage can enter that door unhindered.
Visible crew/equipment: When Station 51 arrive at the movie studio, after the car's explosion Captain Stanley tells dispatch to respond another engine, mobile aid unit, and another ambulance. In the next shot from the interior of Engine 51, the cameraman and camera are visible in the passenger side mirror.
Continuity mistake: In nearly every episode, the dark blue jackets that Gage and DeSoto wear suddenly appear and/or vanish and then reappear, numerous times, while en route in their squad, or when they pull into the stationhouse and Rampart. Since stock footage is usually used when showing all the guys getting into their vehicles, Johnny's hair length may differ as well.
Continuity mistake: Gage and DeSoto arrive at the apartment complex, home to the guy trapped in the couch. They park the vehicle and walk on the gated balcony to the apartment. In the exterior shot, when they enter the doorway the inside wall to their left is bare and the corner of the balcony's iron gate is to the doorway's left. Next interior shot, now there is a large painting on that previously bare wall and the iron gate is directly in front of the door. When they leave, their vehicle is farther away, positioned differently.
Continuity mistake: When the guys begin to use the pulley system to lift the car engine off the injured man, the women stand to the officer's left (viewer's right), but in the next close-up it is switched, then back again in the wideshot.
Deliberate mistake: At the station, Gage is washing dishes and talking about his idea for a new poker game. In this shot the camera is positioned behind the kitchen's top/lower cabinets and sink, facing Gage. The fact that we can see the back side of the cabinetry (paper towel dispenser which hangs over sink is gone) ruins the illusion of this POV from the wall that should be there.
Loose Ends - S6-E12
Visible crew/equipment: When the guys bring Brackett to the hospital after his car accident, two white tape, and one black tape actors' T-marks are all visible on the floor in the ER.
Continuity mistake: After the guys lift the car engine off the man and Kelly maneuvers the car backwards, the same close-up of the officer and two women that was shown a few shots earlier is shown again, even though the car is now moving farther back.
Revealing mistake: In many of Dixie's close-ups the use of the soft focus lens is rather apparent. This could be an acceptable directorial decision, were it not for the fact that in some shots where there's movement (of a hand, for example) that passes through the corners of the shot, the thick 'hazy cloud' is blatantly visible and quite distracting.
Revealing mistake: After Gage gets bitten by the rattler, when the driver of Tractor 2 begins ascending the cliff, there is a nice close-up as he passes and this young stuntie is most certainly not the older driver seen in this scene. Not to mention the watchless driver suddenly acquires a black watch and a plastic face shield attached to the helmet.
Peace Pipe - S2-E5
Continuity mistake: After Gage catches fire from flammable hose 'water' and removes his jacket outside, when DeSoto walks to his Engine Co., the gloves he holds switches hands between shots.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
