Woah! Those sirens are the sound of fire engines on their way!

Firefighters do these training exercises all the time. So how do you think the firemen are going to put out the fire? Let's watch and see.

They're pulling out a long ladder and that will mean they can get right up to the top where we can see the smoke on the fire tower.

This fireman has a giant hose, and just look how much water is coming out of the end of that.

The water is coming out so fast and it's so powerful that it's able to reach all the way up to the top where the smoke's coming out of the fire tower.
