How Come Firefighters Use Water?

Question

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?

When you poor it over an open flame, the flame is extinquished. Hence, water puts out fire and why it is used.
