Factual error: In this episode Blackwall Station is shown as a London Underground tube station. Blackwall Station is a Docklands Light Rail (DLR) station. Also look at the destination sign on the front of the train, which reads 'THAMES LINE', No such line/station exists on the London Underground.
Revealing mistake: In the episode when ACO Bulstrode is looking at the newspaper cut-out of the appliance crash (the one that Bayleaf was involved in), look closely at the cut-out. The whole article consists of the same paragraph written twice. Seemed the producers were too lazy to write a full article, hoping no-one would notice.
Other mistake: During the shout at the beginning, when the workman is hanging dangerously close over the electricity transformer, Nick is informed by the electricity board that they cannot get closer than 15 feet without it arcing. So why isn't the transformer arcing when the workman is hanging just under a foot from it?
Deliberate mistake: Before the gas explodes in the sewer, you can see the base of the Davy lamp glow red. Except that in real life this doesn't happen; the flame simply turns blue and grows taller in the presence of gas. This was probably done to make the scene more dramatic, though.
Revealing mistake: The flashover in the disused factory's ventilation duct (where the pop video is being shot) craftily borrows a shot of the flashover in the laser arcade shout from Series 7 episode 5. The arcade's overhead walkway and the icon of the woman holding the laser gun is visible.
Factual error: In this episode Nick rides the pump. However, being Station Officer, he should be riding the pump ladder. The London Fire Brigade always has the Station Officer in charge of the pump ladder and not the pump (it's the Sub Officer who is in charge of it).
Continuity mistake: On the way to the second shout at the council accommodation, the fire appliance shown is YHV 194T. Whilst this was the pump in the pilot and first series, for the second series, the appliances were GYW 627W and GYW 628W. (00:43:00)
Continuity mistake: During the petrol station fire, Hallam goes to rescue two attendants trapped in the station shop. The first external shot shows the inside of the shop on fire, but when it switches to the interior shot where Hallam tells them to run for it, there's no fire at all.
Continuity mistake: During the car chase scene, the car passes a petrol station and heads straight towards a bus. Then the next shot shows the car on a clear piece of road where the bus and petrol station have disappeared, but in the next shot the car swerves into the petrol station seen before. The car was going straight, without turning onto any side roads.
Continuity mistake: When Billy and Sicknote go upstairs after their encounter with Pitbull, they go upstairs to change into uniform. The camera follows them upstairs. The appliance bay has no other firefighters present. When the camera pans back down, a full roll-call is taking place in the appliance bay, including Billy and Sicknote who just went upstairs to change few seconds earlier. This was probably done intentionally but it sure does look ridiculous.
Deliberate mistake: When the appliance crashes into the drunk driver's car and flips over, water is seen spilling out of the top of the appliance. This appliance was specially designed to flip over by mounting the water tank at the top, to make it unstable enough to tip over.
