Rear-Mount Rescue-Pumper Fits Seamlessly into Warrenton (MO) Fire Fleet

1 The Warrenton (MO) Fire Protection District had Rosenbauer build this rear-mount rescue-pumper with a Waterous S100 2,000-gpm pump, a 1,000-gallon water tank, and two 40-gallon foam tanks for Class A and Class B foam Sentinel Emergency Solutions.)

Because a major interstate snakes its way through the center of its coverage area, the Warrenton (MO) Fire Protection District has set up all of its engines as rescue-pumpers. And when it came time to replace an aging pumper that had reached the end of its useful service, Warrenton turned to Rosenbauer for a new rescue-pumper but one with big differences compared with its other rigs.

“All our vehicles are on a replacement cycle of 20 years of front-line service and five years in reserve before they are replaced,” says Mike Owenby, Warrenton’s chief. “We have about 10 miles of Interstate 70 that run through our fire district, which means lots of motor vehicle accidents and tractor trailer accidents. That’s why all three of our engines are set up as rescue-pumpers.”

Pump Panel Location

Warrenton’s truck committee produced a list of the things it liked about a 2009 rescue-pumper it had purchased from Rosenbauer and then spent a lot of time looking at other vehicles in neighboring departments. “The committee made a lot of changes to what we wanted in our new rescue-pumper,” Owenby points out. “They wanted a rear-mount pump and a pump panel at the rear of the officer’s side to protect the operator when working on the interstate. We also wanted our extrication tools mounted in the front bumper and our crosslays at the rear of the vehicle.”

Brian Franz, executive vice president of Sentinel Emergency Solutions, who sold the rescue-pumper to Warrenton, says he delivered a rear-mount rescue-pumper to Lincoln County, Missouri, in 2012 and told the Warrenton truck committee it should take a look at it, which they did. “Once they saw that pumper, they were sold on the rear-mount concept,” he says. “Their new vehicle has a shorter wheelbase than their older side-mount pumper, and it has at least 100 cubic feet more storage space, with full height compartments on both sides.”

Todd McBride, apparatus specialist at Rosenbauer, says one of the main advantages of a rear-mount pump with a pump panel at the left or right rear is the field of view that it offers the operator. “With a setup like that, the operator has a 270-degree field of view of a scene instead of 180 degrees like you would find on a side-mount pumper,” he points out.

McBride adds that the Warrenton rescue-pumper carries a little bit more water than most rescue-pumpers. “Warrenton chose to have a 1,000-gallon water tank plus two foam tanks of 40 gallons each-one for Class A foam and the other for Class B,” he says.

Another interesting feature of the rig, McBride says, is its kneeling feature. “The rear axle has an air ride suspension where the operator can push a button on the pump panel and lower the rear of the vehicle about six inches so the rear step and hosebed are even more accessible,” he notes.

Preconnects and Rescue Tools

Franz notes that the Warrenton truck committee wanted preconnects to be easier to deploy and reload, which is why they were located in the rear bumper. “It’s an all steel bumper that’s tied directly into the frame rails, so there’s no concern about its strength or stability,” Franz says. “The covered trays hold two 200-foot sections of 1¾-inch preconnected hose. At the other end of the truck, in the front bumper, is a 100-foot section of 1¾-inch preconnected hose.”

Owenby says the preconnect in the front bumper can be used as a trash line or as a protection line when operating the hydraulic rescue tools. The front bumper also holds two 100-foot hydraulic hose reels, two preconnected rescue tools, two air horns, and a Federal Q siren.

“We spend a lot of time on the interstate, so with the rescue tools up front, we can nose into a scene with the tools easily available and still use the vehicle itself as a blocker for traffic,” Owenby says.

Jeff Dunn, a Warrenton firefighter and member of the truck committee, notes that tactically, having the rescue tools up front instead of in a side compartment makes deployment much quicker. “With the tools in the front bumper, you don’t have to waste 35 feet of hydraulic hose running up the side of the truck to get to the scene,” he says. “Plus, we saved all that compartment space that would have been used by the hydraulic reels and the tools.”

Equipment Storage

Warrenton spec’d all roll-up doors on the rescue-pumper’s compartments, including a roll-up door to cover the intakes and discharges that are recessed into the rear of the vehicle. The truck committee also moved the hydraulic ladder rack to the left side of the vehicle. “On our two previous pumpers, we had push-through-tank storage for the ladders, but we made them easier to get to by putting them in the hydraulic rack that comes down to 40 inches off the ground,” Dunn says.

Owenby notes that the rescue-pumper is set up so each side is dedicated to a particular type of operation. “For this rescue-pumper, the left side of the vehicle is set up for rescue and extrication, while the right side is set up for fire suppression operations,” he says. “The left side has all the technical rescue and vehicle rescue equipment, so we don’t need the ladder rack down for those situations. All the fittings and adapters for the pump operator are on the right side of the vehicle in a Respond Ready toolbox under the pump panel.”

Pump and Lighting

For fire suppression, the rescue-pumper carries a Waterous S100 2,000-gallon-per-minute (gpm) pump and a Waterous 200-cubic-feet-per-minute (cfm) compressed air foam system (CAFS). It’s set up with Elkhart electric CAFS valves, a Fire Research Turbo Foam 400 foam injection pump with auto flush, Elkhart internal butterfly valves on the steamer connections, an automatic direct tank fill plumbed internally to a rear six-inch intake, and a Rosenbauer automatic air primer. Its hosebed holds 1,000 feet of five-inch large-diameter hose and 600 feet of 2½-supply line.

The vehicle also carries a Command Light LED light tower with six Fire Research Spectra Q20 light heads; an 11.5-kW diesel generator; Rosenbauer Green Star Idle Reduction technology; Fire Research Spectra LED scene lights; and PowerArc warning lights, light bar, and rear traffic advisor.
