Why do you send so many fire vehicles to a fire, especially a small fire?

There are a number of specialized roles that firefighters undertake on a fire call, and it is necessary to have enough firefighters on the scene of an incident. Firefighting is a very labor intensive activity. If you get behind because there are not enough firefighters on the call, it is more difficult to extinguish a fire quickly. Also, adverse weather conditions can certainly play a role as well. The basic philosophy is to have more than enough firefighters on scene.
