14.20
- Slide 21
- Ladder Selection Once target identified What length of ladder
is necessary? What will be done with the ladder? Will ladder be
used at several locations? Is a straight or extension ladder
needed? Additional considerations Ground condition Accessibility of
location Available personnel 14.21
- Slide 22
- Butt Section Ground slopes Proper climbing angle is 75 degrees.
Placed under the target Butt should be carried in the direction of
the target. 14.22
- Slide 23
- Fly Section Tip of fly dictates how ladder will be used.
Placement of tip will be important. Windows Roof level Fire escapes

Ladder placed with the tip at the top of the windowsill to either
side. (A)(B)
- Slide 25
- Special Uses Can be used as tools or as portable stairs Ladder
integrity not compromised 14.25
- Slide 26
- Removal of Numerous Victims Method Raise ladder Ascend and
secure victim Descend escorting victim For several victims, use two
or more ladders. One supply ladder can service many escape ladders.
14.26
- Slide 27
- 14.27 Multiple ladder rescue technique.
- Slide 28
- Chute with a Tarp Prevent water damage Ladder with salvage
cover, plastic sheet, or tarp can be used as a makeshift chute to
direct water out a window. 14.28
- Slide 29
- Over a Fence Two short ladders tied together in an A-frame can
be used to climb over fences. There are times a fence cannot be
cut. 14.29
- Slide 30
- Elevated Hose Streams Locations that could not be approached
conventionally Basic safety practices Firefighter and hose secured
to ladder Ladder must be stabilized at base or tip. 14.30
- Slide 31
- 14.31 A handline can be used off a ground ladder for difficult-
to-reach areas. Note the use of a ladder belt.
- Slide 32
- Portable Pool Three or four ladders can be tied together to
form a crib and lined with a tarp. Filled with water Used to
capture runoff 14.32
- Slide 33
- Barrier Secure dangerous areas Provides a positive visual
deterrent 14.33.
- Slide 34
- Support With ropes, a ladder can be secured to substantial
objects. Only as an emergency structural stabilizer 14.34 Should be
replaced as soon as possible with tools designed for the
situation
- Slide 35
- Hoist Point A-frame hoist Pulley and rope are attached. Ladder
weight limits 14.35
- Slide 36
- 14.36 A-frame hoist.
- Slide 37
- Ventilation Fan Supports Short ladder spanning an opening
Innovation tempered with safety 14.37
- Slide 38
- Safety Common sense Gloves Correct ladder Overhead wires must
be considered live. When on a ladder, firefighter should keep three
limbs in contact. 14.38
- Slide 39
- Overhead Obstructions Injury potential Tree limbs, structural
overhangs Television and telephone wires Overhead electrical lines
14.39 A ladder can make an electrical connection to ground.
- Slide 40
- Climbing Path Passageway a firefighter climbs through while
ascending ladder Obstructed paths Firefighter is required to alter
normal climbing angle. Squeeze through a tight space. Breathing
apparatus must be considered. 14.40
- Slide 41
- 14.41 Climbing path pass-through area.
- Slide 42
- Ground Considerations Ladder must be stable. Ground must be
level. Dangerous lateral lean 14.42 Uneven ground effect is
magnified as the ladder increases in height.
- Slide 43
- Ladder Load Number of people permitted on ladder Load capacity
Recommended maximum load label 14.43
- Slide 44
- 14.44 Ladders must be positioned properly and not
overloaded.
- Slide 45
- Working Off a Ladder Firefighter secured to ladder Ladder belts
Safety harness Leg lock 14.45 Leg lock.
- Slide 46
- Ladder Storage More than two support points Flat surface Avoid
the same contact points when storing. Apparatus ladder storage
Stored under cover in compartments De-icing products 14.46
- Slide 47
- Ladder Apparatus Parking Park ladder apparatus at an angle to
the fire building to ensure ladder access Leave room for removal of
ladders. 14.47
- Slide 48
- Ladder Painting Should never be painted as a means of
maintenance Small areas should be painted. Identification
Visibility Quick reference Hoist points 14.48
- Slide 49
- Certification and Testing Procedures NFPA Standard 1931 When
ladder model is designed, rigid testing is needed. Ladder label
14.49
- Slide 50
- Ladder Skills Common terminology and technique Commands Common
sense 14.50
- Slide 51
- Carrying Ladders Techniques used for carrying ladders: Suitcase
carry Shoulder carry Flat carry Firefighter can carry a small
ladder. Victims 14.51
- Slide 52
- Raising Ladders Several considerations Heel of ladder distance
from building Climbing angle about 75 degrees Number of
firefighters needed to raise a ladder will vary. Most situations
call for two firefighters. 14.52
- Slide 53
- The working length is the distance from the ground to the point
where the ladder contacts the building. The ladder is placed at a
point approximately one- quarter of the working length from the
building.
- Slide 54
- Rung and Beam Raises Two methods of raising a ladder:
Two-person rung raise Two-person beam raise Raising an extension
ladder: Fly extension raise Three-person raise Four-person ladder
raise safer than three-person raise 14.54
- Slide 55
- 14.55 (A) Beam raise. (B) Rung raise. (A) (B)
- Slide 56
- Leg Lock Secure firefighter to ladder Both hands needed Ladder
belt Second alternate leg lock known as hyper- extended leg lock
14.56
- Slide 57
- Carrying Tools When carrying tools, security is sacrificed.
Tools should be passed up. Tools can be hung on an upper rung and
climbed to. Tools can ride up the rails of an aerial ladder.
14.57
- Slide 58
- Mounting and Dismounting Getting on and off a ladder is the
most difficult action for the uninitiated. Height increases. If
ladder is not secured by rope, it should be heeled. When climbing
into a window from a ladder, two methods are used. Special care
should be observed when mounting or dismounting ladder from
ornamental works. 14.58
- Slide 59

directly Hook ladder 14.59
- Slide 60
- Hoisting Ladders by Rope Need to use ladder from elevated When
lowering ladder, procedure is reversed 14.60
- Slide 61
- Types of Truck-Mounted Ladders Many types of ladder trucks are
used today. Each designed to serve a particular function Aerial

- Slide 65
- 14.65 A snorkel basket can reach places not possible with other
types of apparatus.
- Slide 66
- Lessons Learned Ladders have many applications. Different types
of ladders are designed for a specific use. Ladder use is packed
with additional dangers that each firefighter must respect.
