After unwrapping the large box on the kitchen table, the alarm goes off. They enter the apparatus bay on the fire engine side, which is their shower, lockers and bunks; the kitchen and office are on the other side of the building, by the rescue squad truck.
When the trailer is on fire at the front of the station, the trailer tongue jack is already touching the ground. The captain runs over and starts raising the trailer off of the car hitch. The coupler on the trailer was not engaged.
When the burned boy was taken by ambulance at the station, the ambulance was a Ford model. When the ambulance is shown backing up at Rampart, it is a Chevrolet model.
The station wagon that is towing the trailer disappears and leaves room for the ambulance to park to pick up the burned boy.
When treating the boy from the trailer, the paramedics tell Dr. Early that he is burned on his upper right arm and upper right leg. But when Dr. Early is examining the boy in the treatment room, he describes the burns as being on the right forearm.
When treating the boy that is burned in the travel trailer, Gage states he has given 100 liters of O2. Oxygen is stated in liters per minute and given normally to patients @ 4-8 lpm. Also, any delivery system only goes to 25 lpm.
John and Roy bring groceries back to the station. The bananas are already rotten.
When a fireman runs up to disconnect the burning trailer (and presumably drive the car out of harm's way) the trailer had already been "prepped." The jack wheel was already lowered to the ground and the the fireman did not have to release the tongue latch.
After John and Roy are informed of the injury to the crossing guard, they are told to continue as normal. The Squad truck is never impounded to be checked for damage or other signs of being in a hit and run, which is what would normally happen.
