As Johnny rappels down from the stuck amusement park Sky Ride, in the first two shots he has nothing on his back, but in the third he's wearing a backpack.
When Gil started CPR, he began with a precordial thump. This was used only within 60 seconds of the heart stopping. Once given, the victim should be checked for a heart beat. The idea is that it momentarily stops the heart in the hope that it will restart in the normal synchronous beat. He also hit too hard. The proper way is to raise the fist about 1 foot above the chest and then just let it drop. No muscle is used.
A king cobra spits venom into Roy's eyes and into a glass shield held by Gil. King cobras are not classified as spitting cobras and cannot spray venom.
When Squad 51 pulls out of the station, only Johnny and Roy are seen, but when the Squad pulls up on scene, Gill was between them in the cab.
As The Squad Leaves The Station To Respond To The Man Down Call, The Older Crown Fire Truck Can Be Seen In The Truck Bay Not The Newer Ward LaFrance.
Both the go-cart rescue and the Sky Ride rescue take place at Queen's Park in Long Beach. The name is shown on a sign in one shot and several Long Beach landmarks such as the Queen Mary and Island Grissom are clearly visible. Long Beach has their own fire department and would not require the services of the LA County Fire Department.
