As the American Fire Service keeps trending towards high flow, low pressure attack packages it is important to understand what Dennis LeGear refers to as ‘gold standard’ for fire stream development in this episode.
Stream movement and stream angle have a major impact on fire attack and getting water to the seat of the fire.
THE LOST EPISODE! We are excited to share with all of you “The Lost Episode” of Brass Tacks & Hard Facts.
In the well-read October 2007 Fire Engineering Article “How Kinks Affect Your Fire Attack System” Jerry Knapp along with Tim Pillsworth, Christopher Flatley, and Doug Leihbacher go into great detail how kinks affect your fire flows.
Nozzle/Hose Whip is a term often used for erratic movement and kinking in smaller, 1.5 coupling hand lines at the nozzle position. Often referred to as a "nozzle weight" problem; hose construction and diameter inconsistencies are often the greatest variables.
Jerry Herbst discusses how "hose/nozzle" whip may surface in evaluation of attack line packages.
Brian Brush discusses bringing efficiency and accuracy to your engine mounted master stream by the simple addition of a gate valve.
In this episode, Jeff Shupe compares in detail 2" versus 2-1/2" with a side-by-side comparison showing that while the 2" hose line has its applications, the 2-1/2" is still the "King of hose lines".
In this episode Jeff Shupe reviews the historical evolution of 2” hose and its fit in today’s fire service as an intermediate size hose line, balancing high flows with mobility utilizing a 1-1/16” tip with a target flow of 240 gallons per minute.
