Water On The Fire
Track 1 Dennis LeGear
Fully Understanding water delivery through Hose & Nozzles
Handlines; from Rig to Seat of Fire
A detailed look at Handline Hose, Handline Nozzle Selection and Handline Fire Stream Development / Application.
This class will look at all the items that go into gold standard simple critical handline flow, areas discussed in detail will be:
Hose construction/design (Tru Hose Concept)
Nozzle construction/design (CVSS, Solid Tip and Automatic) Pros and Cons
Needed Handline flow a review of the Iowa and NFA flow formulas
Handline Fire Stream effective reach, foot print of extinguishment
Stream Air Entertainment (What is the new UL understanding shedding light on?)
Water dispersal/mapping (Can we really wet adequately from the exterior?)
Playing of the handline stream the when and why? (Overhead, O, T, Z, I)
Impacts of Wye Operations (Line Commitment and Responsibility)
Standpipe design impacts on SP attack packages as it relates to smaller hose line, what are the limits factors?
Attendees should be able walk away with a better understanding of the complex thoughts of design spec and layout of equipment as it relates to handline fire stream development. This will include a understanding of stream selection and its impacts. This deeper understanding will provide the insight needed to make wise decisions as it relates to purchasing of new equipment whether it is replacement equipment or entirely new significant change over current equipment.
Track 2 The Brass Tacks & Hard Facts of Hose & Nozzle Selection
Brass Tacks and Hard-ER Facts: Behind and Beyond the Series
This 8-hour course will take you behind the scenes of the making of the Brass Tacks & Hard Facts engine company training video series and beyond the facts presented. It will be a deep dive in to the gamut that is the engine company discipline, specifically, heightening awareness to the various types of equipment that create fire streams and developing a basic understanding of the different types of nozzles in use today. It exposes the following critical factors contributing to success of the firefighter interaction with this equipment: Flow, function, relationship of pressure to GPM and limitations due to nozzle reaction. Specific manufacturer data will be presented to make a case for selections citing industry trends. Instigating change, committee development, and trial benchmarks will be discussed in detail. Lecture and hands on format will be combined to ensure each student has the comfort level to go back to their own department and evaluate and test their own fire flow system.
A basis of understanding is developed drawing on statistical information from UL, NIST, ISO, NFPA 1710 section 5.2.3, 1720 and 1962.
Course Activity and Timeline
Classroom session with interactive power point:
Training ground activity:
Establish target flow and flow test engine through a hands on nozzle/hose comparison
Demonstrate how to properly setup and calibrate an inline flowmeter
How and where to measure inline pressure to determine friction loss through rig plumbing and hose layout
How to measure nozzle pressure using inline and pitot gauges and the differences in between
Hands on flow stations for comparative flows and nozzle reaction with all nozzle types (smooth bore, fixed, selectable, automatic) and tip pressures (50 psi, 75 psi, 100 psi)
How to record and interpret flow data, friction loss, and nozzle reaction and find balance in selecting an appropriate hose and nozzle package
Students will leave understanding the WHY behind an effective fire attack package and how a cut and paste solution is not always the best solution
An attendee for this class is an Engine Company disciple looking to expand their basis of knowledge. They could be currently involved with an active hose and/or nozzle evaluation, in the planning stages to define the objectives and benchmarks of an evaluation, or just looking for a better understanding of accuracy validating effectiveness in fire stream development. Member’s working to promote alternative attack options in an organization resistant to change will benefit from a “best practices” approach based on facts rather than opinion.
