As Anthony Kastros has noted, the American fire service continues to deal with a leadership pandemic. Yet new leaders are emerging at all levels to fill the vacuum, none perhaps more critically than in the role of the company officer. In the first of a series of discussions on fire department leadership, Rachael Staebell and Bassel Ibrahim join Kelly Crummer of Firehouse Subs for a roundtable discussion on leading at the company level.

Part 2 followed the stream of water from the intake to discharge, examining the control systems it contacts along the way. Part 3 addresses pump control. Controlling the pump is paramount in getting the proper amount of water to the fireground. This is mainly done by the engine throttle. The more revolutions per minute (rpm) the operator commands the engine to produce, the faster the pump spins, throwing more water out of the discharge. How the operator interacts with the pump has evolved with technology. It is critical that the operator understands how the throttle control system controls the pump discharge. Engines using independent throttle control and a discharge relief valve control the flow and pressure of the water, allowing the operator to be the brains behind the controls. This is the first method of control discussed in the series.

ANALOG ENGINE CONTROL

After the air bleeder, relief valve, and intake valve, the water will come to the pump. The velocity of the pump impeller controls the flow and pressure developed at the discharges. The speed of the engine controls the speed of the pump. Engine throttle designs have evolved over the years with improvement in technology and changes in regulations. Initially, a cable was connected directly to the engine throttle from the pump panel. This was the tried-and- true Vernier throttle. Twisting the knob to the left tensioned the cable, increasing rpm. Turn the knob to the right, and the rpm went down. In the middle is the red emergency idle button. Many operators use this button as the normal means to bring the engine to an idle at the end of operations.

 

This puts added stress on the engine—it should be slowly brought to idle after working to pump water. It is the equivalent of running a marathon and immediately plopping on the couch with a bag of chips—your body would not appreciate this style of cool down, and neither does your engine.

Engines started using fly-by-wire throttle systems in the late 1990s. This technology evolution required fire apparatus manufacturers to adapt and make the throttle control on the pump panel electronic. Electronic throttle controls can have a knob or up and down pushbuttons. Many may say, “I have a rig from the 2000s and still have a Vernier throttle.” Open the pump house and see if a cable or several wires are connected to the Vernier dial. It is a good bet it is wires, as many departments want a controller to look and act like what they used for many years. The one thing the electronic throttle and Vernier throttle have in common is the need for an operator to make adjustments to develop and maintain pressure. I refer to this control setup as the analog engine.

DISCHARGE PRESSURE RELIEF VALVE

Analog engines need a way of controlling spikes in the discharge pressure. Spikes occur when multiple handlines are flowing

CRAWFORDVILLE, Fla. (AP) — Authorities rescued people trapped by floodwaters and more than 3 million customers were in the dark across much of the southeastern U.S. as Hurricane Helene weakened to a tropical storm over Georgia early Friday after making landfall overnight in northwestern Florida as a Category 4 storm.

Helene came ashore amid warnings from the National Hurricane Center that the enormous system could create a “nightmare” storm surge. There were at least four storm-related deaths.

Video on social media sites showed sheets of rain coming down in Perry, Florida, near where Helene made landfall, and siding being torn off buildings. One local news station showed a home that had flipped over. The community and much of surrounding Taylor County were without power.

In Citrus County, some 120 miles (193 kilometers) south of Perry, first responders were out in boats early Friday to rescue people trapped by the flooding.

“If you are trapped and need help please call for rescuers – DO NOT TRY TO TREAD FLOODWATERS YOURSELF,” the sheriff’s office warned in a Facebook post. The water may contain live wires, sewage, sharp objects and other debris, they posted.

With maximum sustained winds of 70 mph (110 kph) , Helene continued to weaken while moving farther inland over Georgia. The storm was about 40 miles (65 kilometers) east of Macon and about 100 miles (165 kilometers) southeast of Atlanta, moving north at 30 mph (48 kph) at 5 a.m., the hurricane center in Miami reported.

“We expect it to weaken further. It’s going to turn northward and turn northwestward and eventually move into Tennessee and Kentucky, and merge with a funnel system up in that area,” said Jack Beven, a senior hurricane spec

Rural Development U.S. Department of Agriculture posted the following story on its Web site:

Located in the Highlands region of Maine, the town of Greenville has long been a vacation destination. In recent years, the community has welcomed even more visitors pursuing outdoor recreation and lakeside living. While the influx of seasonal residents and tourists has been good for area businesses, it also puts an increasing burden on fire, police, and EMT services. Town leaders knew they had to modernize their public safety facility to maximize efficiency for their small corps of staff and volunteer emergency responders. Under the guidance of Town Manager Mike Roy, the little town with a population of fewer than 1,500 people built a new 20,000 square-foot public safety building in the heart of town, paid for in part with a USDA Rural Development Community Facilities grant.

In use since the spring of 2024, the new facility is a victory for the community, where the need for emergency services has been rising at a rapid clip. Greenville’s emergency responders cover not only the town but also the massive area in and around Moosehead Lake, with its more than 400 miles of coastline and 80 islands. The town has just three full-time police officers, one full-time fire chief, and about 10 volunteer firefighters on any given day, so the responders need an efficient workspace and good equipment to do their jobs successfully. Replacing a 60-year-old structure, the modern new facility should serve the town’s needs for years to come.

Functionality, efficiency, and safety were priorities in designing the building. It is equipped with critical features like specialized equipment to decontaminate and launder firefighters’ uniforms and an exhaust removal system for the fire truck bays. It is also spacious, with a large community room, separate police and fire department offices, exercise and bunk space for rescue staff, and ample storage and truck bays. Says Police Chief Jim Carr, “The new facility represents growth not only for the Town of Greenville, but the Moosehead Lake region as well. It offers appropriate space to complete the job. It also offers room for a regional training center for both fire and police and has been designed to allow for area expansion 50 years out.” 

Local Rural Development staff supported Mike Roy and his team as they completed the paperwork for the Community Facilities Grant, finalized plans for the structure, and managed the budget. Mike Roy cites the USDA architect, Bill, and loan specialist, Nathan, as being particularly helpful. (“The support from Rural Development was amazing,” said Mike. “Nathan made the process understandable. When a problem arose, he’d say, ‘We’ll get through this,’ and he’d find a way to make it work.”)

Greenville’s Rural Development Community Facilities Grant was awarded through the Congressionally Directed Spending (CDS) process. This means that Maine’s two legislators, U.S. Senator Susan Collins and U.S. Senator Angus King, both advocated for the project and secured the federal appropriations legislation necessary. When the funding was announced, Town Manager Roy noted that “This facility would not be possible without the help and support of Senator Collins and Senator King. Their support represents federal dollars, not only coming back to Maine, but coming our region.” 

USDA Rural Development Maine State Director Rhiannon Hampson echoed that sentiment, saying, “Greenville’s new public safety building highlights the collaboration between our Congressional Delegation and USDA Rural Development. Together we are bringing Community Facilities investments to rural Maine towns, leveraging federal dollars to modernize infrastructure and meet the needs of locals and visitors.”
