Engage in a class that provides the knowledge and understanding to produce a spec-driven fire stream-focused engine for both supply and attack while effectively meeting your other local requirements. This new class will combine both classroom and a hands-on outside look at a couple of engines covering the nuts and bolts of urban/suburban engine design revolving around the big three components of a triple combination pumper: the chemical wagon, the hose wagon, and the steamer. The “chemical wagon” component, aka the booster tank for rapid fire attack, will cover capacity, shape (L, T, square), impacts to body layout, tank-to-pump sizing (3-inch vs. 4-inch), weight, and UL data on required amounts of water to suppress private and multiple dwelling fires. The “hose wagon” component, aka the hosebed, which is the beating heart of the pumper, will cover 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. The “steamer component”, aka the main pump, will cover plumbing spec and layout that are often overlooked with their major impacts to performance, from too few intakes to too many discharges; ensuring the overall plumbing including pressure pickup 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.
