CHAPTER 14 Introduction Ladders are used for many purposes besides providing access to elevated locations. Ladders were originally constructed from wood, now truss type beams are used. Truss construction allows for stronger and lighter ladders. Continuous advances allow for ladders of various sizes and uses to be developed.
CHAPTER 14 Ladder Terminology 1 of 2
CHAPTER 14 Ladder Terminology 2 of 2
CHAPTER 14 Ladder Companies Apparatus carrying ladders and other devices, tools, and personnel. Tower ladders and articulating boom ladders. Ladder company tasks include: Forcible entry. Search and rescue. Roof access. Ventilation.
CHAPTER 14 Aerial Ladder Apparatus-mounted ladder reaching 100’- 110’. Designed so various sections slide out from one another. Bed is attached to a turntable.
CHAPTER 14
CHAPTER 14 Tower Ladder A telescopic boom with mounted basket. Helpful to remove many victims. Very versatile piece of equipment.
CHAPTER 14 Articulating Boom Ladder Uses basket with articulating booms. Capable of placing bucket into hard to reach places. Also known as snorkel ladder.
CHAPTER 14 Types of Ground or Portable Ladders Straight Extension Roof or hook Folding A-frame combination Pompier
CHAPTER 14 Straight Ladder A fixed length ladder. Range from 12’ to 20’. Can usually be carried and raised by one person. Used for access, ventilation and escapes.
CHAPTER 14 Extension Ladder Two or more ladders operating as a unit. May have 2 or more fly ladders. Halyard used for extending ladders. Ladders over 40 feet have stay poles.
CHAPTER 14 Roof Ladder Straight ladder with retractable hooks at tip. Used when operating on a sloped roof. Hooks are placed over the ridge of roof.
CHAPTER 14 Folding (Attic) Ladder Enables access into narrow and confined spaces. Length of 8’ to 16’. Collapsible feature. Ideal ladder to reach sprinkler shutoff.
CHAPTER 14 A-Frame Combination Ladder Can be used in various configurations. Fly ladder can be manually raised. Can be used as step ladder. Works well in tight places.
CHAPTER 14 Pompier Ladder No longer an approved ladder. Was used as hanging ladder to climb up. Ladder raised manually to window levels.
CHAPTER 14 Maintenance, Cleaning, and Inspection Fire service ladders warrant special attention. NFPA Ladder needing repair must be taken out of service. Detailed maintenance records should be kept of required inspections.
CHAPTER 14 Cleaning Ladders Dirt and grime can negatively affect ladder operation. During cleaning, ladders should be inspected closely. Follow manufacturer’s recommendations on cleaning.
CHAPTER 14 Ladder Safety 1 of 2 Use common sense. Overloading ladder limits is the most common cause of ladder-related injuries. Ladder placement is a critical element. Ladders should not be in front of lower floor window or door. Use of correct ladder is important.
CHAPTER 14 Ladder Safety 2 of 2 Must be careful of overhead wires. Always keep three limbs in touch with the ladder. Always have someone butt the ladder. Always use a safety belt or leg lock when working off a ladder.
CHAPTER 14 Ladder Uses 1 of 2 Used primarily for climbing. Can provide a path to heights. Can be used to descend or as a bridge. Commonly used for rescue. A roof ladder provides stability while working on sloped roof. Can be used to remove glass
CHAPTER 14 Ladder Uses 2 0f 2 Can be used to support weight. Water can be applied from a ground ladder. May reach areas where apparatus mounted appliances may not reach. Can serve as an exterior work platform.
CHAPTER 14 Ladder Selection Considerations Ground conditions Height needed Purpose Slope of ground Accessibility of location Available personnel Overhead considerations Raising space considerations Stability
CHAPTER 14 Raising Skills: Concepts Heel of ladder must be a certain distance from the building for stability. Safest climbing angle is about 75 degrees. Prior to climbing, determine proper distance for ladder from building.
CHAPTER 14 Raising Ladders Two-person raise One-person raise Beam raise Rung raise
CHAPTER 14 Special Uses Removal of numerous victims. Chute with a tarp. Over a fence. Elevated hose stream. Portable pool. Barrier. Supporting of falling sign. Forcible entry. Hoist point. Ventilation fan supports.
