Visible crew/equipment: At the abandoned refinery, just after Roy attempts to pull out the man pinned under a tank, but is unsuccessful the first time, when it cuts to Captain Stanley and Chet, who are on the third level hosing the fire through the doorway, at the left of the screen a crew member is visible, watching them.

Visible crew/equipment: When Roy moves the squad forward to tow the wrecked car away from the flames, as he opens the driver side door to get out, we can see the reflection of the silver reflector screen in the squad's long wing mirror.

Visible crew/equipment: When Engine 51 first arrives at the abandoned refinery and stops to hook up to the hydrant, the multiple location set lights are reflected on the engine's large windshield.

Revealing mistake: When Johnny and Roy are figuring out how to free the woman trapped in her wrecked car, the flames spread and Johnny's pant leg catches fire, but as he's trying to smother that flame, the strip of fire stunt gel that was smeared on his pant leg is visible.

Other mistake: When Station 51 is dispatched to the traffic accident, while en route first we see Engine 51 with nobody on the back, but then we see two firemen standing at the back, and they are Johnny and Roy. This footage is from the episode "The Old Engine" in season 3, when Station 51 got the new Ward La France engine, and since the previous shift was still out with the squad, Cap told Roy and Johnny to jump on the back and join them on their first run with the new engine.

Continuity mistake: In the opening rescue where Roy and Johnny rescue the woman from the burning car, Johnny is relaying the woman's vitals to Rampart. Over his right shoulder, you can see a sticker on the trunk of the car behind them. This is probably a dealer sticker. In one scene, it is blue and red, and in another, it is blacked out. It returns to blue and red, only to be blacked out again.

Continuity mistake: After the ambulance Roy is riding in is involved in a traffic accident, when Johnny arrives he jumps into the back with the injured attendant and patient, and we can see that the stretcher's footrest is light brown. But when the attendants exit, they carry the stretcher out of the back of the first ambulance then wheel it to the second ambulance, and the footrest is now red. It would seem that they merely transferred the patient from the first ambulance's stretcher to the second ambulance's stretcher while still in the ambulance, but they couldn't have done that because two full size stretchers cannot fit into the back of that first station-wagon style ambulance, especially with attendants back there, so they would have had to do the patient transfer on the ground outside. Hence the problem.

Continuity mistake: The cut that Roy receives over his eyebrow during the traffic accident changes characteristics, such as when he and John are at the poker game, it looks considerably better in following shots, then it looks much worse again.

Continuity mistake: Just before the ambulance Roy is riding in is involved in the collision, we see a crowd of people at the corner near the stop sign, but in the next shot they've all vanished, only to reappear just as the vehicles collide.

Continuity mistake: After they load the woman from the wrecked car into the ambulance, Roy and an ambulance attendant are riding in the back with her. In the shots of the moving ambulance, until it's involved in the traffic accident, we should be able to see Roy and the attendant through the windows, but they're simply not there.

Visible crew/equipment: When the ambulance that Roy is riding in is involved in a traffic accident, the ambulance driver, Hal, comes out to help, and the outline of the mic transmitter is visible on the back of Hal's white shirt.

Continuity mistake: When the victims are loaded onto the second ambulance with Roy, after the original ambulance was hit by the car, we can see the license plate, Z99977, as Johnny closes the back doors. Then while en route to Rampart, the ambulance's make/model changes with plate, Z99953, then the make/model changes yet again, but still has the same plate, Z99953.
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
