Basic Firefighting: Ground Ladders

SPO 2-1 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.

EO 2-1 Identify the purpose of fire service ladders.

EO 2-2 Demonstrate the proper placement of ladders and a safe climbing technique as it pertains to advancing hoselines.

EO 2-3 Describe the techniques of using ground ladders to support fire streams.

EO 2-4 Raise all portable ladders carried on the apparatus using the flat or beam raise, and climb correctly the full length of those ladders (NFPA 1001 (1997) 3-3.5).

Instructional Guide

I. Ground Ladder Operations (2-1)

Introduction

• Within height and personnel limitations, ground ladders can be effective in number of operations

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

• Some uses same as aerial units, but others unique

• Gaining access to fire building and exposed buildings

• Advancing hoselines when stairways are used by people escaping

• Replacing damaged stairways

• Removing trapped victims

• Removing people from crowded fire escapes

• Getting from one roof level to another

• Reinforcing weakened building features

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

• Ladder Work

• Ladder work should be assigned to those performing truck duties

• If laddering duties not specifically assigned, rescue or fire attack operations can be delayed

• Ladder operations affect the efficiency of most other fireground operations

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

• Handling Ground Ladders

• Several ways to carry ground ladders from apparatus

• Method used should require least maneuvering and time

• There should be no need to lay ladder on ground after carrying to building and before raising it

• One way to avoid extra movement is to carry it with rungs and trusses parallel to ground - once butt in position near wall, lower to ground while upper part of ladder raised from shoulder height

• Ladder can then be pivoted and extended if necessary

• Two- and three-person ladders can be quickly placed for beam raise

• Two-person ladder is carried with fire fighters on opposite corners

• Three-person ladder carried with two fire fighters at each end of one truss and one in the middle on other truss

• Four person ladders carried by two fire fighters at each end and additional crew members at or near middle

• If manufacturer makes no recommendation, position fly section away from building

• Climbing angle is determined by height of raise and distance from butt to building - butt to building distance one-quarter of height of raise

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

• Safety

• Be careful of overhead obstructions, especially electric wires

• Once ladder raised, should be tied in to building or braced by fire fighter

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

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

• Once ladder used to enter building, it should be left in place as exit
