Prepared by a team of fire control officers, the training guide is designed to help fire crewmen learn the fundamentals of water use. The entire package can be used for a complete course or individual lessons and can be adapted to specific training needs. Throughout the guide, emphasis is placed on one primary training objective, performance in real fire situations. The main sections of the guide include: (1) Supply: drafting water from a source below the pump and from a pressurized source, trouble shooting through gauge readings, and use of ejectors; (2) Delivery: delivery equipment, hose lay systems, planning water delivery systems for mop-up, water use hand signals, care of hose and fittings, connecting hose and fittings, broken hoses, and locating equipment; and (3) Application: principles of water application, initial attack with water, mop-up, and selecting or outfitting a tanker. Lesson plans provide objectives, instructor and student references, and step-by-step lesson presentations. Many lessons contain exercises appropriate for indoor fire training. Most lessons direct the instructor to specific visual aids (vu-graphs/transparency masters, slide/tape programs, and films). More than half of the document consists of instructional photos and the cross-referenced appended vu-graphs/transparency masters. (EA)
