The Perfect Stream

perfect-streamA real world approach to fire stream management

Whether it be a fire in a single family residence, a highrise fire, or a surround and drown big water fire, the weapon of choice in today’s fire service is the stream producing appliance AKA the nozzle and the ammunition is good old water. Methods of attack can require different types of fire streams made up of a specific flow (GPM), stream patterns, and fire stream exit pressures. This class is going to analyze the various types of fire situations and the types of nozzle, hose, and appliance combinations required to successfully achieve a fire knockdown as safe and efficiently as possible. Emphasis will be placed on utilizing equipment to its maximum capabilities while keeping within the recommendations of the equipment manufacturers themselves.

Some of the topics that will be covered include:

  • High flow handlines used for the offensive blitz attack. Again we will be showing various nozzles and nozzle pressures as well as the use of 1-3/4″, 2″ and 2-1/2″ hose. The highlight of this portion will be showing how an 1-3/4″ and 2″ blitz lines can deliver 400 GPM with one firefighter and a 500 GPM 2-1/2″ handline with two firefighters both done safely and efficiently.
  • Analyzing the highrise handline under real world system pressures to show that there are other options besides the 2-1/2″ handline.
  • Master stream operations to include smooth bore tips utilizing higher than the standard they are currently rated to get high velocity and far reaching streams without breaking any rules set by the equipment manufacturers.
