Wildland fire engine
A wildland fire engine is a fire engine specifically designed to assist in fighting wildfires by transporting firefighters to the scene and providing them with access to the fire, along with water or other equipment. Most commonly used by the United States Forest Service, there are multiple types of wildfire apparatus which are used in different scenarios. According to the National Fire Protection Association, if the apparatus will be used primarily for outdoor and wildland responses, than it is to be considered a wildland fire apparatus and must conform to NFPA 1906.
Depending on where the engine is stationed it may carry as much as twice the national standard in fire hose. In areas where there is rugged terrain that keeps engines from driving directly to the fire, large hose lays are installed to transport water to the fire area. In desert areas with moderate terrain, less hose is used as it is easier to access the fire. Often the technique of pump-and-roll is used where the vehicle drives with the pump engaged while a firefighter uses a hose to spray water on the fire. This technique allows a team of two to flank the perimeter of a fire.
==Features==
Wildland engines are traditionally smaller than standard fire engines and are primarily used for vegetation fires or wildland fires. They also respond to emergencies in the back country where traditional engines cannot respond. Most wildland engines feature four-wheel drive capability and can thus climb hills and make it through rough terrain. One of the features that makes these engines ideal for vegetation fires is that they can pump water while driving, whereas most, but not all traditional engines must be put into park to flow water, it depends on the specifications to which the Fire Department wants the vehicle to be built. This pump-and-roll feature allows the engines to make "running attacks" on vegetation fires, a tactic that can help minimize the rate of spread by having a firefighter walk the edge of a fire with a hose line and the engine trailing close behind.〔(【引用サイトリンク】url=http://sbcfire.ndic.com/wp-content/uploads/2012/05/Type-3-Engine.pdf )〕
