Engine Design: Water Delivery Focused - From Urban to Suburban

#FDIC2024
An engaging FDIC 4-hour workshop that provides the knowledge and understanding to produce a spec driven fire-stream-focused engine for both supply & attack while effectively meeting your other local requirements. This presentation will discuss the nuts and bolts of urban/suburban engine design revolving around the big three components of a triple combination pumper: The Chemical Wagon, Hose Wagon and Steamer:
First, the “Chemical Wagon” component, a.k.a. the booster tank for rapid fire attack. We’ll discuss capacity, shape (L, T, Square), impacts to body layout, tank-to-pump sizing (3” vs 4”), weight, and UL Data on required amounts of water to suppress Private and Multiple Dwelling Fires. Second, the “Hose Wagon” component, a.k.a. the hosebed, which is the beating heart of the pumper. Bed width, length, free board (depth), and the collective design impacts on both supply and attack evolutions. Further discussion includes the pros and cons of crosslays, front bumper designs, and the opportunity to build out both attack and supply functions. And finally, the “Steamer Component”, a.k.a. the main pump. Plumbing spec and layout are often overlooked with their major impacts to performance, from too few intakes to too many discharges; ensuring the overall plumbing including pressure pick up locations, foam loop (issues), flow meters and pump sizing that is designed correctly and in balance with the mission of simple best practices fire stream development. Finally, where all water flow is controlled from the pump panel itself: clean, simple, and easy to operate - the devil is in the details.
This class will be offered all Monday AM, Monday PM, Tuesday AM, and Tuesday PM at FDIC 2024
