Easton officials hope a new online tool will prod residents and merchants to provide information for firefighters who might be dispatched to a blaze at their addresses.

The Easton Fire Department has launched a Community Connect portal to coincide with Fire Prevention Week, which begins Oct. 6, Chief Henry Hennings said.

The free service will let residents and business owners upload pertinent information about building or business occupants, and their needs in the event of an emergency. That might include that a building houses someone who is bedridden, or contains stored hazardous materials.

The portal can include emergency contact information, relevant fire alarm system components and their locations, and special hazards such as oxygen cylinders in the property.

The information could help first responders do their jobs faster and more efficiently, potentially preventing serious damage, injury or deaths, according to Hennings. It also ensures that information provided to the department is current. When an emergency is dispatched, an alert goes to the fire department’s mobile response system listing the incident address.

Hennings said anyone in the city can participate. Subsequent property owners would have no access to information entered by previous owners, he said.

Hennings said anyone who wants more information can contact firefighter Ian Insley at 610-250-7762, or go to communityconnect.io/info/pa-easton online.

In this webinar, presented by Chase Downey, you’ll learn about station wear history and trends, along with the basics of a systems level approach to PPE. All in the name of giving you extra layers of protection during exposure to fire above (in this case, below) and beyond your bunker gear.

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
