If you want to be a firefighter you have to fill out a long form and do all kinds of tests.
Part of the tests you have to do are - pulling down a dummy, pull up a ladder and walk up and down stairs. You have to be strong so in the physical test you have to carry a big tank of water.
Firefighters respond to emergency calls in a variety of ways. Firefighters can help you when a baby is stuck in the car, a cat is stuck up a tree, they help in a car crash and they all so put out fires.
