Session Reference: 5

Topic: Firefighter Pre-Basic V

Level of Instruction:

Time Required: 3 Hours

Materials:

• Two Fully Equiped Pumpers

• Static & Preasurized Water Sources

References:

• Essentials of Fire Fighting, Fourth Edition, IFSTA, Chapters 11 & 12

Preparation

Motivation:

Objective (SPO): The firefighter will demonstrate a basic knowledge of the hose use to supply water to the fire scene, the appliances required to move water, hose loads, and lays used for supply at the emergency scene along with the basic techniques to conserve property during a fire situation.

Overview: Firefighter Pre-Basic V

• Introduction to Supply Line Operation

• Hose Loads

• Hose Lays

• Salvage Operations

Instructors Notes: This lesson should be delivered as a combination of demonstration and student practice with the minimum amount of time spent on lecture. This material is designed to give the student some basic information on supply line operations and salvage. It is not intended to replace a Firefighter I program nor make the individuals fully-functional firefighters. It includes some basic information that any new firefighter should know to assist in an exterior mode on the fireground. Instructor should have apparatus, supply hose, and salvage covers available for display, demonstration, and handling.

Instructional Guide

I. INTRODUCTION TO SUPPLY LINE OPERATIONS (5-1)

Sources of Water

• Pressurized systems - hydrant systems

• Static sources - ponds, lakes, swimming pools, etc.

• Apparatus tanks - water carried by the apparatus

-------------------

Hose Construction

• Rubber lined, fabric covered - used for supply and attack lines, sizes range from 1-inch to 5-inch

• Rubber lined, reinforced, rubber covered - used for obtaining water from static sources, sizes range from 2-1/2-inch to 6-inch

• Polymer impregnated - used for attack or supply lines, sizes range from 1-1/2-inch to 5-inch

-------------------

Hose Couplings

• Three- or five piece threaded coupling - male end fix with exposed threads, female end swivels, equipped with rocker lugs for tightening and loosening

• Storz - quarter-turn coupling with sexless ends

-------------------

Hose and Coupling Damage

• Apparatus driving over it

• Heat and flame

• Abrasion from dragging

• Chemical damage from fire runoff

• Rupturing from over pressurizing

-------------------

Hose Appliances

• Double male - used to join two female couplings

• Double female - used to join two male couplings

• Reducer/increaser - used to connect couplings of different diameters

• Wye - used to divide one line into two

• Siamese - used to combine two lines into one

• Humat valve - used to connect hose to a hydrant, turn the hydrant on, and still permit other apparatus to connect to the hydrant without shutting it down

• Ball valve/hydrant gate valve - used to stop the flow of water in a hoseline

• Spanner wrench - used to tighten or loosen hose couplings

• Hydrant wrench - used to turn the operating nut on a hydrant
