1. Garden tractor
   Mini wagon
2. Pickup wagon
   Grass wagon

Sometimes the standard firetrucks just aren't practical for accessing the scene of a fire. In some wild fires for instance, firefighters use a specialty pickup known as a grass wagon. Equipped with a hose and water pump, it's ideal for tackling small blazes.

An interior attack means fighting the fire from inside the structure. To maximize safety, it always requires at least four people -- two to go in, and two to stay back for backup or rescue.

1. Water
   Heat
2. Alarms
   Wind

GPM stands for gallons per minute. This information is critical to firefighters as they calculate the best way to battle a blaze.

   Kill oxygen to the fire
2. Revive overdosed patients
   Change the color of traffic lights
