• Essentials of Fire Fighting, Fourth Edition, IFSTA, Chapter 9

Preparation

Motivation:

Objective (SPO): The student will demonstrate a basic understanding of ground ladder operations, positioning fire streams with ladders, carrying ground ladders, raising ground ladders, and climbing ground ladders.

Overview: Firefighter Pre-Basic IV

• Introduction to Ladders

• Lifting, Raising and Carrying

• Rescue Using Ground Ladders

• Ground Ladder Practical

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 ground ladders. 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 ladders available for display, demonstration, and handling.

Instructional Guide

I. INTRODUCTION TO LADDERS (4-1)

Kinds of Ladders

• Aerial ladders - mounted on apparatus and operated mechanically

• Ground ladders - carried and raised by hand

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

Ladder Construction

• Solid - beam constructed of solid material

• Truss - beam constructed with top rail and bottom rail and rung plates connecting the rails and supporting the rungs

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

Ladder Types

• Roof - a single section ladder with hooks on the tip end that can be folded out for securing to a roof

• Extension - a ladder consisting of at least two sections that can be extended to various lengths

• Folding - a small ladder that folds for storage and is compact for use in tight areas such as accessing an attic

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

Ladder Parts

• Single section ladder

• Heel - bottom end of ladder

• Tip - top end of ladder

• Beam - side pieces that support rungs or steps

• Rungs - part of ladder used for climbing

• Foot - bottom end of each beam

• Roof hooks - hooks on tip end of roof ladders

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

• Extension ladder (in addition to those on a single section ladder)

• Bed section - bottom section (part that rests on ground)

• Fly section - part that extends; may be more than one fly section

• Halyard - rope or cable used to extend fly sections

• Dog - assembly to hold fly sections in place when extended

• Pawl - part of dog that fits over rung

• Pulley - part of ladder on which halyard rides

• Stop - part of ladder that stops sections from coming apart when being extended

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

Safety

• Be careful of overhead obstructions, especially electric wires

• Once the ladder is raised, it should be tied in to building or braced/heeled by a firefighter

• Ladder should not be overloaded - firefighters should be at least ten feet apart at normal climbing angle

• If the climbing angle is decreased or hose is being carried up, the distance between those on ladder should be increased to twenty feet
