Continuity mistake: When Brackett tells Morton that he can go keep Early company while he awaits test results, Brackett's wearing a patterned tie, and when Brackett walks into treatment 3 his tie is tied differently.
Visible crew/equipment: When Roy and Johnny are in the basket with the man who was electrocuted, after they finally get the victim on the ground and surround him, the shadows of the cameraman/camera are visible mainly on Roy and Captain Stanley.
Visible crew/equipment: When John and Roy get back to the station, Captain Stanley asks them to step into the office, and as Cap walks through the doorway the camera's shadow is visible on the wall at the left. Also note the coiled electrical wire lying on the floor in front of the squad, and the shadow of something that is directly in front of the squad, even though the squad just rolled in.
Continuity mistake: When Johnny and Roy are in the basket with the man who was electrocuted by a power line, they are atop three more power lines. Chet and Mike cut the two outer lines and only the center line remains, but in the closeup of the basket there are still three power lines under the basket.
Continuity mistake: After Dr. Early fixes the squad's engine problem, while Roy is driving we see a two-way radio mounted at the top of the dashboard, just past the steering wheel. When the dispatcher calls on Squad 51 to respond, there's a closeup of the Motorola two-way radio/Interceptor units which are mounted under the dash (near gas pedal), and Johnny lifts this mic, but then we see that he's speaking on the mic from the top of the dash. Additionally, in those two closeups of the two-way radio, we can see the gas pedal, but Roy's foot is nowhere to be seen, even though the squad has been moving all along.
Other mistake: After getting the hermit out of the cave, Roy asks Marco to take the EKG leads "over there", but then hands them to Chet (played by Tim Donnelly) saying "here Tim", and the subtitles read that Roy says "Chet."
Visible crew/equipment: When the woman staggers into the ER a nurse rushes over, and the actor's T-mark is visible on the floor in front of the admitting desk, where the nurse was just standing.
Visible crew/equipment: When Roy and Johnny climb the tower to rescue the man at the top, Johnny slips and Roy helps him down the ladder. When Chet begins his ascent, twice there are shots looking down the center of the tower, and in those two shots the cases of production equipment are visible on the landing where the camera is situated. The print on one case reads "400' MAGS", referring to the filmmaking magazines.
Other mistake: During the fire at Hammond Chemical, when Engine 7 rolls up and lays duals, we can see the vinyl material adhered to the top of the cab covering the engine company's real number.
Continuity mistake: Roy and Johnny move a barking dog, who is tied up in front of a hermit's rock-faced cave, and retie the dog to a branch in some bushes, but in following close-ups of the dog he is still tied up at the original spot.
Continuity mistake: When Chet quickly takes off his turnout coat, one of the sleeves is inside out when Johnny uses it on the dog, but then both sleeves are right-side out while he and Roy are trying to subdue the dog.
Continuity mistake: When they bring the Hermit into the ER, Brackett tells them to take him to treatment 4 and he's wheeled there, but in the shot from inside the treatment room we see that he's actually inside treatment 1.
Continuity mistake: While climbing the tower to rescue the "man" at the top, after Johnny slips and slams into the cross beam, when he and Chet are heading back down the tower, the two lights attached to the tower keep switching from the right side to the left side, depending if it's a closeup of them or a wide shot of their doubles. Additionally, in the closeups the lights are large and round, but in the wide shots one of them is a small square.
Continuity mistake: After the woman has staggered into the ER she is seated in the wheelchair, and when she jumps out of the wheelchair there is a tall ashtray can behind her beside the wall, but in the next shot that tall ashtray can has vanished.
Continuity mistake: After Station 51 is dispatched to the fire/explosion at the chemical company, when John heads inside to rescue the chemist, the SCBA cylinder he's wearing has one white sticker and one pinkish sticker. By the time John brings the victim out to the sidewalk, his air tank has changed back and forth repeatedly to one that has two red stickers.
Visible crew/equipment: Just before the hermit leaves Rampart, the actor's mark is visible on the floor in front of the market owner's feet, and when Dixie turns the hermit's wheelchair, the tape mark in front of Brackett becomes visible.
