This course is designed to introduce students to advance techniques for supplying high flow fire streams through tower ladders. Tower ladders, when properly utilized, are awesome firefighting machines capable of extinguishing large amounts of fire. Supplying a tower ladder at the scene of a fire can be extremely taxing on the water supply system. These incredible machines are often times capable of delivering flow rates of up to 2,000 GPM. This requires the engine companies tasked with supplying these tower ladders to be extremely proficient in their water delivery techniques.
