Plot hole: When Bo Jenson visits Richard Allen, he takes the elevator at the far south end of the ER wing, near the ER nurses' station, straight up to the 6th floor and then turns left to get to Richard's room in the short hallway, by the windows. When Richard jumps out the window and lands on the ledge, we see he's on the south side of Rampart's main building. Considering the actual floor plan of the hospital, this is completely impossible. The ER is located in the south lower wing and only has two floors, so Jensen could not have gone up to the 6th floor from the elevator he took.
Other mistake: Richard is in room 603 and jumps out of the 6th floor hallway window. In the long shot of the exterior of the building, we see that he's lying on the ledge of the row of windows that are second from the top. The elevator shows 8 floors, which means that he's actually lying on the 7th floor's window ledge.
Continuity mistake: When Roy and Dr. Brackett are on 127's Snorkel while Johnny is trying to subdue Richard on the ledge, Brackett is not wearing any rings, but after loading Richard into the Stokes, when Brackett is grabbing hold of the basket in the closeup he's wearing two rings on his left hand, which vanish in following shots.
Visible crew/equipment: After Squad 51 is dispatched to 'woman down', just as the squad rolls up in front of the apartment building we can see a bit of the camera's production equipment at the bottom left corner of the screen, which is then pulled quickly out of shot.
Continuity mistake: When Roy and John walk into Edna Self's house, in her closeups she's wearing a light beige floral robe, but in the shots facing the guys we can see that it's a dark solid color robe that's on the chair. Notice how odd it is that the three are not in any shots together - Edna's not in any shots facing John and Roy, and they're not in any shots facing her.
Revealing mistake: When Richard jumps out of the 6th floor window, in the interior shot we see that he lands right at the base of the window's frame, as his body bounces back from the impact, but when Brackett looks out the window Richard is lying on the ledge, which is much farther down than the window's bottom frame.
Other mistake: When Johnny and Roy get back to the station, Chet tells Johnny that Paula's going to come by around 12:30 PM, then when the dispatcher sends Squad 51 on the 'woman down' run he says "Time out 12:22." When the guys get back to the station again, Paula tells Johnny that she arrived around noon and that Engine 51 left on a run shortly after.
Continuity mistake: When Richard jumps out of Rampart's 6th floor window, the bottom of his feet are very filthy (impressive for someone in bed in a catatonic state), but when he wakes up while lying on the ledge and Johnny tries to control him, Richard's feet are now pretty clean.
Continuity mistake: When Bo goes to Richard's room for the first time, in the view from inside the patient's room, as Bo pushes open the door we can see the hallway behind him, and there's a perpendicular wall beside the door. This wall does not exist when he visits Richard the second time, because there's a hallway leading to the elevator outside of Richard's door.
Continuity mistake: When Bo Jensen goes to Richard's room for the second time, as he pushes open the door we can see there's a wall perpendicular to the door, but when Bo is in the room there's a wide widow covered with curtains where that wall was. The window with curtains can also be seen in the exterior shots, when Richard jumps out the hallway window.
Continuity mistake: After Johnny finds the missing mechanic, when he turns him over from his stomach to his back, Johnny's wearing a watch on his left wrist, but in the closeup showing Johnny's arms turning the catatonic mechanic over, Johnny's watch has vanished.
Continuity mistake: When Roy and Johnny try to subdue the out-of-control patient on Rampart's ledge, after Brackett tells them that he'll go to x-ray right away, Roy's helmet is off, but in the overhead shot it's on his head, then in the next shot Roy puts it on his head.
