In this video:
One of the first challenges that firefighters face when they arrive at a fire is finding a suitable water source that provides enough water for the type of fire they are fighting. Common sense tells us a car on fire will require much less water than a burning apartment building. There are formulas used by firefighters that will tell them approximately how much water is needed to fight a given fire (see bonus facts below). Fire hydrants are commonly color coded to indicate how much water a particular hydrant will provide. This allows for quick decision making when they are deciding which hydrant to access.
