Continuity: Season 1, episode 6, 'Dealer's Wild': 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.

Revealing: Season 2: In at least three episodes, which include 'Saddled', 'Peace Pipe' and 'Women', the same corner restaurant/hot dog stand (with a striped orange/white awning and green vinyl bar stools) is featured. That would be fine, if it weren't for the fact that in each episode the street it is located on has a different name and different cross streets. It is obviously a set on the Universal Studios lot.

Continuity: Season 2, episode 12, 'Helpful': When DeSoto starts to crack about what's upsetting him, Gage places a mop beside another mop, up against the door and it falls over. Next shot both mops are upright and in different positions as well.

Continuity: Season 2, episode 9, 'Women': 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: Season 2, episode 7, 'Fuzz Lady': At the stationhouse, when DeSoto and Gage are discussing the detective, in the shots facing Gage, DeSoto holds a cup of coffee in his hands, but in the shots facing DeSoto his cup is on the table.

Visible crew/equipment: Across whole show: When the guys are wearing their helmets, multiple head set lights are usually reflected on the black surface, more often than not.

Continuity: Season 2, episode 1, 'Decision' (aka 'Problem'): 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.

Continuity: Season 1, episode 6, 'Dealer's Wild': When Gage plays the new game of poker with Kelly, the entire left side of the table is visible as the two begin. Next shot, DeSoto is suddenly sitting at that end, with an additional cup and saucer, opposite Kelly and Gage.

Continuity: Season 1, episode 7, 'Nurses' Wild': When Gage rides in the ambulance with the cardiac and gunshot patients, the windows between him and the drivers are opaque glass. In the next exterior shot, as they drive down the street, those interior windows are transparent.

Revealing: Season 2, episode 12, 'Helpful': En route to the pick-up truck hanging from the freeway on-ramp, there is a flipped shot of Engine 51 and Squad 51 as they drive under the freeway before the camera pans in towards the car. Some giveaways are the reversed '51' on the Engine and the reversed 'road construction ahead' sign.

Continuity: Season 2, episode 10, 'Dinner Date': When DeSoto and Gage arrive on scene at the traffic accident, the boy and his bicycle lying on the ground change positions between wideshot and close-up.

Continuity: Season 2, episode 9, 'Women': When Christy walks into Station 51's kitchen, the bag strap is on her shoulder, but close-up it is gone, only to be back next shot when she removes it a moment later.

Continuity: Season 2, episode 5, 'Peace Pipe': 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.

Revealing: Across whole show: When Engine 51 and/or Squad 51 are dispatched, the shots of the vehicles while en route to the call or even en route to Rampart, in many instances, are stock footage or repeat shots which show the same traffic, same parked cars, same people, etc., from previous episodes. The same occurs when they actually pull out of Stationhouse 51 - it's actually pretty amusing to see the same cars across the street, in countless episodes.

Continuity: Season 2, episode 1, 'Decision' (aka 'Problem'): At the stationhouse, when the captain draws the diagram of the plastics company set-up on blackboard, the chalk drawing differs between shots.

Visible crew/equipment: Season 1, episode 11, 'Hang up': At Rampart, when Dixie walks over to Dr. Brackett, who stands behind the station, the tape mark is visible on the floor, just before she steps precisely on it.

Continuity: Season 1, episode 6, 'Dealer's Wild': When Frankie flies the Cessna, he places an oxygen mask on his father. The style of the mask changes from either a round, large type, to a smaller, square type.

Continuity: Season 1, episode 4, 'Cook's Tour': When Squad 51 arrive at the house with the woman in labor, first there is a wideshot of the home and front yard. In the next close-up, the actual style of the house changes - note the roof and its three dormers, and bushes appear/disappear.

Continuity: Season 2, episode 9, 'Women': The shaving foam on DeSoto's face changes between the face-on shots and the reflection shots, and in the reflection he shaved from cheek to chin, but in face-on shots only to the neck.

Continuity: Season 2, episode 5, 'Peace Pipe': To send the drug box up to Gage and DeSoto on the scaffolding, Kelly loops the rope and ties a knot, but in the next shot, when Gage pulls it up it's a different kind of knot and loop.
