Wildland urban interface (WUI) apparatus typically are a mix of wildland and Type 1 engines, usually with a short overall length, good angles of approach and departure, and a chassis that can handle both highways and rough terrain. These vehicles are becoming a staple of fire department fleets where the urban interface meets wildland terrain and are being built in a number of configurations.
Merging Types 1 and 3
Ken Lenz, vice president of engineering for HME Inc., says his company has introduced the Ahrens-Fox WUI engine, a merger of Type 1 and Type 3 pumpers built on a 4x4 short front overhang (SFO) chassis and medium four-door cab. The vehicle has a rugged off-road bumper and a skid plate that covers the radiator, tubing, and air lines as well as a 1,500-gallon-per-minute (gpm) pump with HME’s Distributed Water System™, a 500-gallon water tank, and a 150-gpm diesel-driven pump for pump-and-roll.
Lenz points out the Ahrens-Fox WUI has a 22-degree angle of approach, a 26-degree angle of departure, one-inch hose reels on the left and right sides, two 1½-inch crosslays, two 2½-inch rear discharges, a 2½-inch discharge on the left side, two 1½-inch discharges and under-spray nozzles at the front, a rear 2½-inch tank fill, and a six-inch steamer and 2½-inch intake on the left side. Ladders and hard suction are stored in the rear of the vehicle where an attached ladder provides access to coffin compartments on top of the rig.
John Schultz, director of pumper and custom chassis products for Pierce Manufacturing, says Pierce recently built a WUI PUC pumper for the Oklahoma City (OK) Fire Department with a 1,500-gpm pump, 750 gallons of water, a foam system, a Darley 2.5AGE auxiliary pump for pump-and-roll capability, and a front-mounted bumper turret. “It’s a multipurpose vehicle with a short wheelbase to make it more maneuverable,” Schultz observes, “with extra storage capacity and seating for five firefighters.”
Doug Feldman, western regional manager for Rosenbauer, says the trend today is to merge the Type 1 and Type 3 concepts together into a WUI-capable engine. “We take the high angle of approach and departure and four-wheel drive common to a Type 3 along with its short wheelbase and marry it with a Type 1 pump of 1,500 gpm, 750 gallons of water, and a National Fire Protection Association (NFPA) complement of ground ladders to get the WUI vehicle,” Feldman says. “Rosenbauer uses a body mounting called metacones on these vehicles that allows the body to flex, which is very helpful when traversing rougher terrain.”
Ken Howenstine, sales engineer for Burton’s Fire Inc., says Rosenbauer’s normal high-pressure pump, which comes in 1,250- and 1,500-gpm versions, “works very well in the wildland environment where water conservation and the dispersion of the water droplets is very important.”
