I know there are certain types of fires that, if one uses water on it, will get worse. But as far as I know, firefighters use water tanks and fire hydrants for virtually every fire too large for a fire extinguisher to do the job.
Is it an issue of if the source isn’t large enough or too far away it doesn’t matter? How do they know the kind of fire before reacting to it?

Because water is almost everywhere and does not cost much, is easy to use and is safe.
The fire engine has a big water tank inside so that when we get to a fire , we can start putting out the fire as soon as we get there. We can put out a small fire with that, a car or some woods on fire. If it’s a bigger fire like in a house, school or big accident, we need more water than we have on the truck. We can get more water from a fire hydrant with a hose from the one down the street. The hose on the back is 1000 feet long and is like a big heavy pipe on top of the road when it has water in it. If we have to get water from a lake or river or ocean, we can connect the hard hose, it’s like a big straw, to the fire pump on the side of the fire truck and suck the water up from the lake and then pump it to another fire truck at the fire. We would use the big hose from the back of the truck for that too. If you have a swimming pool, we can use the fire truck to suck water out of it to put out the fire. Sometimes if there is no fire hydrant or lake out pool, we use firetrucks with bigger tanks to drive the water to the fire. Some are as big as a gasoline truck.
