But then all dark rides and all themed installations in all visitor attractions would be illegal and should be shut down.
Im sorry but this is like saying because Smiler crashed then coaster block mechanisms aren't safe. There's specific circumstances and complexity there
It is nothing like saying that at all because the safety block system worked fine. It was manually overridden by a human. That is hugely different to the point I am making.
Two major dark rides quite literally burnt to the ground, very quickly and very fast. The goal of fire suppression is to suppress the fire is it not, the clue is in the name. Therefor, it would not be out the realms of possibility to assume that rides that have fire suppressed sets would actually slow the speed of the fire, would it not?
How does that even suggest something should be shut down? It does not.
What I am saying is, the speed and ferocity of not only Europas pirate ride but WWH, suggests that in these situations, fire suppressants on the sets does not do much to slow the speed of the fires. Given what we saw with our own eyes about how fast the fires spread. This also suggests that once ignited, the sets become very flammable, clearly they are else the buildings would not burn like they did.
You stop a forest fire by removing fuel, aka wood from the fires path. Fire retardant materials could be compared slightly to removing fuel from the path of a fire. So even if the fire started outside the building and was large by the time it got to the sets, it should have slowed the pace of the fire down once reaching the ride. The opposite happened, the fire sped up and went from large to absoloutly huge, clearly suggesting there was some highly flammable materials inside, else the fire would not go from a large one to a huge one.
You need three things for a fire; heat, fuel and oxygen aka the fire triangle. The oxygen and heat were already there in the Europa fire before hitting the pirate ride, once the fire hit the pirate ride the fire went hugely bigger, I mean HUGELY. The only thing that would have changed according to the fire triangle before and after hitting the building would be the fuel. In this case, becoming far more flammable once hitting the pirate ride.
