In the fall of 2007, the National Wildfire Coordinating Group agreed on a set of standards for all fire engines that are used for wildland firefighting. If you have an auxiliary pump that is putting out 100 gpm at 200 psi at 800 RPMs, there is sufficient pressure to use the flow and pressure reducing valves to maintain steady, constant handline performance. The Type 3 Engines traditionally have four-wheel drive to make driving over rough terrain easier, they can also be produced with standard rear wheel drive. Forest Fires Advantages and Disadvantages.

Airtankers are very effective on small, initial attack operations and: When there is quick follow up by ground forces. The water may even receive pollution from the smoke and ash, which can harm marine life the biome as well. The smaller the nozzle size, the higher the nozzle pressure.

Fires involving solid material as well as flammable liquids can be controlled and extinguished using high expansion foam. Type 6 fire engines have a maximum GVWR of 19,500 lbs. The lead engine takes the heat out of the fire and the second engine is used to follow the first engine, picking up hotspots and securing the line. Of course, these forests dont just remove trees; they kill and displace wildlife, alter water cycles and soil fertility, and endanger the lives and livelihoods of local communities.

Where do you begin when making a flanking attack with an engine? If the fire is spotting, use the airtankers to hold the spot fires until ground forces can be positioned to control. All engines have Class A foam capability. When you consider the fact that wildland firefighters are also engaging in extremely strenuous physical activity and battling blazing flames, its not hard to understand why dehydration poses such a large safety threat. Tall Timbers Research Station in Tallahassee, FL, ran an experiment on the local forest biome for over 40 years. Rushing water also picks up debris, rocks, and even vehicles on its way down to create more damage. Dont expect much power until the engine reaches 1,000 to 1,200 RPMs. That information can then be compared to the slow speed chassis performance to see if it will work.

Breathing in the heated smoke can create respiratory system problems or worsen chronic heart and lung diseases. Future generations then lose the chance to study these older trees, enjoy the biome they create, and the other benefits that such a forest provides. During extended attack, engine crews support fireline production, structure protection, and helicopter operations. When an old-growth forest loses its foundational members, then there is no way for them to return. The crew can hike or be flown to fires in more remote areas. They also respond to emergencies in the back country where traditional engines cannot respond.
