Continuity mistake: At the ferris wheel, when the boy starts to climb down to help the man in the lower seat, in the closeup he steps on the two yellow, fluorescent tube light bulbs causing the bulbs to plummet and shatter on the ground below. The problem is that those two fluorescent bulbs did not even exist in the prior wide shots, that lamp socket space was empty.

Daisy's Pick Blind Date - S4-E7
Other mistake: When Squad 51 is dispatched to "man needs assistance", in the exterior shot as the squad rolls out of the apparatus bay we can see Engine 51 still inside the bay, but the real Station 127's engine is parked right beside the station house.
Continuity mistake: When Roy and Johnny are on the roof with Harriet, we can see the shadow being cast by the utility pole on the street down below, and when the police car shows up moments later that shadow has changed significantly. (00:12:40)

Greatest Rescues of Emergency - S7-E5
Other mistake: After getting their promotions, Roy and Johnny start recalling their history together and when Johnny remembers joining the paramedic program he says he was at 8's, but Johnny was at 10's and it even shows the clip from the show's pilot where Johnny's standing behind Engine 10 talking with his Battalion Chief. The filming of the show's Station 10 was done at the real Station 8. As an aside, the real Station 8 was also seen in the 1950's TV show Rescue 8.
