Hydrant to Nozzle Seminar - Carol Stream, IL
Instructors: Dennis LeGear
Date: October 22/23, 2019
Hydrants to Nozzles class is a two day lecture taking a comprehensive look at engine layout, equipment spec (pumps/hose/nozzles) hydraulics and its direct impact on strategies and tactics on the fire ground. Students of all ranks will build a strong foundation for success and be better prepared to make strategic and tactical decisions on the fire ground with a realistic working look at gold standard movement of water from the Hydrant to the Nozzle.
This will include how to best use the equipment you have at hand. Including suggested changes to spec, deployment and equipment layout to vastly improve pumping operations, fire stream development (large and small) and apparatus placement. Items discussed will include the flowing:
- Pump theory (Series, Tandem, Suction to Suction, Pumping)
- Water supply, Hydrants (Understanding main distribution system)
- Hydraulics (Pump Charts, Updating them simplifying them)
- Operating from booster tank (Transition to pressurized source)
- High volume connections to hydrants (Proper way to get the most out of a Hydrant)
- Single and multiple handlines pumping (Line commitment, Line Responsibility, Marking Gauges)
- Setting agency target flow and stream selections (Both small and heavy streams)
- Impact of air entrainment and stream selection (Stream policy at Oakland and D.C.)
- Type and design of handline nozzles (Pros, Cons the good the bad the ugly)
- Type and design/construction of hose supply and handline (Hose fleet its impact)
- Wye Operations (Is it possible hydraulically, Modern flow, Trunk line pressure differential, Wye ops pitfalls)
- Supplying FDC (Sprinkler, Sprinkler/Standpipe Combo, High-rise double your water at pressure)
- Master Stream target flow and nozzle selections (Rapid Attack Monitor, vs Engine Deck Gun vs Platform vs Ladder)
- Supplying MS, Supplying aerials (Supply vs Attack Pumper, Master Intake Settings, Aerial PRVs, Reaction Force Limits, NP is 80 psi best?, Nozzle selection,)
If not laid out correctly / ideally all of the above can and will alter your effectiveness on the fire ground before you ever put the Engine in pump. This detailed approach pre arrival will facilitate better possible extinguishment at all fires. A comprehensive review of common sense approach to engine work, which will reduce unnecessary complexities on the fire ground. A recommitment to basic efficient supply and attack packages with a goal to fully maximize the property and lifesaving potential of the engine company.
Anyone in a position to effect changes or in charge of purchasing equipment is strongly encouraged to attend. Much of the suppression equipment has 10 to 20 years in service times, this class will assist in removing the specter of the 20 year purchasing mistake. The executive rank of the fire service and the rank and file needs more than just vendor interaction…
This class will not sell you anything, but knowledge and review items you already understand, the goal is to jointly create a base understanding of all these interrelated items and their fire ground impacts. Lessons learned can be taken back to your agency and worked, tested, researched etc. to assist your agency in the goal of ensuring the best system possible fire stream development for your jurisdiction.
