Visible crew/equipment: When Dixie tells the attendants to wheel Ruthie, the woman who went berserk at the salon, into the treatment room where Dr. Early's waiting, there are two T-marks visible on the floor at Dixie's and Johnny's feet.
Visible crew/equipment: After Station 51 is dispatched to the fire at the marine salvage yard, when they arrive at the scene we can see a second cameraman on his knees beside the camera, as he is shooting footage of the ship from that specific angle, which we see during this scene.
Visible crew/equipment: After the guys rescue the woman who was trapped upside down in the wrecked car, when they load her into the ambulance, the location set lighting is reflected on the glass of the ambulance doors.
Other mistake: At the end of the episode, when 51's guys are in the kitchen waiting to see the "terrific idea", in the closeup John presses the tape recorder's third white button to play it, and we hear the dispatcher's voice, but in the next shot we continue to hear the dispatcher saying, "1305 Overland Ave, apt C, cross street, Pacific..." despite the fact that we can see all the white buttons are now up, none are actually depressed.
Other mistake: When the woman from the salon is brought into the treatment room she's unconscious, but as they transfer her from the ambulance stretcher to the hospital gurney, she lifts her left arm from under the stretcher bar and then also positions it on the gurney.
Continuity mistake: When Ruthie is wheeled into the ER, Dixie tells the attendants to put her in the treatment room where Dr. Early's waiting, and they wheel her into treatment 2 which has a windowless door, but when they're in the room the door has a window, which means she's in treatment 1, not 2. Plus the fact that both treatment rooms are set up differently.
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
