5.2 Ladder Safety, Placement & Climbing Procedures

The deployment, positioning, and climbing of ground ladders on the fireground present high-risk physical challenges. To minimize the danger of falls, ladder failure, and electrical contact, firefighters must execute standardized safety procedures, placement calculations, heeling methods, and climbing techniques.

The 75-Degree Climbing Angle & Spacing

The stability, strength, and safety of a ground ladder depend directly on the angle at which it is positioned. NFPA and fire service standards establish 75 degrees as the optimal climbing angle.

• The 1/4 Working Height Rule (1:4 Ratio): To achieve a 75-degree angle, the distance from the base of the structure to the butt (heel) of the ladder must be equal to one-quarter of the working height. The working height is defined as the vertical distance from the ground to the point where the ladder contacts the building.

  Butt-to-Building Distance = Working Height / 4

  • Example: If a ladder is placed to reach the sill of a window 24 feet above the ground, the butt of the ladder must be positioned exactly 6 feet away from the wall (24 feet / 4 = 6 feet).
  • Example: For a roofline that is 32 feet high, the butt must be placed 8 feet away from the building (32 feet / 4 = 8 feet).

• Consequences of Deviation:

  • Too steep (angle greater than 75 degrees): The ladder is unstable and prone to tipping backward as the firefighter climbs, as the climber's center of gravity is shifted outward.
  • Too shallow (angle less than 75 degrees): The load capacity of the ladder is severely compromised. Shallow angles subject the beams to extreme bending stress, which can cause catastrophic structural failure. Additionally, the base of the ladder is highly likely to slide out from the wall under the weight of a climber.

• The Arm's Length Test (Verification): To quickly verify the proper climbing angle on the fireground, a firefighter can perform a simple physical check:

  1. Stand upright at the base of the ladder with toes touching the butt spurs.
  2. Extend both arms straight forward, parallel to the ground.
  3. If the ladder is at the correct 75-degree angle, the firefighter's palms or fingers should rest comfortably on the rung directly in front of them at shoulder height, without the need to lean forward or stretch.

Overhead Hazards & Safe Placement Size-Up

Before a ladder is removed from the apparatus or raised, the crew must perform an overhead hazard assessment.

• Electrical Power Lines: The most critical hazard on the fireground is contact with energized electrical utility lines.
  • Firefighters must look up to identify overhead wires before lifting, moving, or raising any ladder.
  • Maintain a minimum clearance of 10 feet (3 meters) from all electrical lines to prevent electrical arcing.
  • Treat all ladders as conductors of electricity, regardless of material (fiberglass and wood can conduct electricity if they are wet, dirty, or damaged).
• Physical Obstructions: Check for building overhangs, gutters, window cornices, signage, and trees that could obstruct the ladder's raising path or cause it to tip.
• Location relative to Building Features:
  • Avoid placing ladders over doors or windows where flame, heat, or heavy smoke could impinge on the ladder or compromise the climbing path.
  • Ensure the base of the ladder is placed on stable, level ground. If placed on soft soil, the butt spurs should be firmly driven (spaded) into the ground. On ice, wet concrete, or asphalt, the ladder must be immediately footed or secured to prevent slippage.

Heeling and Securing the Ladder

A ground ladder must be footed (heeled) or anchored before any climb begins to prevent the base from sliding or shifting.

• Heeling: Footing the ladder to provide a stable base during raising and climbing.
  1. Front Heeling (Under the Ladder): The firefighter stands under the ladder, facing the building. They place their feet against the beams or the bottom rung, and grasp the beams at shoulder level, pushing the ladder toward the structure.

     [!WARNING] The front heeler must wear full structural PPE, including a helmet with the visor down. They must look straight ahead or slightly downward to avoid being struck in the face by falling debris, tools, or broken glass.

  2. Rear Heeling (Behind the Ladder): The firefighter stands on the outside of the ladder, facing the building. They step on the bottom rung or the butt spurs with one or both feet and grasp the beams to stabilize the ladder.
• Securing/Tying Off: When a ladder is left unattended, or if multiple personnel will climb it, the ladder must be secured. This is accomplished by tying the top of the ladder to the building (such as to a windowsill or fire escape rail) or anchoring the base using utility straps, rope, or webbing.
• Fly Section Orientation: Aluminum and fiberglass ground ladders must be raised with the fly section out (facing the climber). Wooden ground ladders are designed to be used with the fly section in (facing the building), unless otherwise specified by the manufacturer.
• Safety Locks and Halyards: Ensure the dogs (pawls) are fully locked over the rungs before climbing. The halyard must be secured to the bed section using a clove hitch and an overhand safety knot.

Climbing and Working Procedures

Ascending and descending ground ladders requires strict adherence to body mechanics and safety guidelines:

• Three Points of Contact: Firefighters must maintain three points of contact at all times (two hands and one foot, or two feet and one hand). Hands should grasp the rungs (or the beams, if using them for sliding contact) to maintain a secure hold. Grasping rungs is preferred because it provides a more secure grip if a foot slips.
• Climbing Mechanics: Keep the body aligned with the center of the ladder, stand upright, and climb smoothly. Avoid running, jumping, or bouncing on the rungs. Look straight ahead, rather than down at the feet.
• Carrying Tools: Carrying tools in one hand while climbing is unsafe as it compromises the three points of contact.
  • Small tools should be placed in a holster, pocket, or utility pouch.
  • Large tools (such as axes, pike poles, or Halligans) should be hoisted using a utility rope after the firefighter has climbed to the working height.
  • If a tool must be hand-carried, the firefighter must hold the tool in one hand while sliding that hand along the underside of the beam, maintaining constant contact with the ladder.
• Working from a Ladder (Securing the Firefighter): When working from a ladder (e.g., executing vertical ventilation or forcible entry), the firefighter must be secured.
  • Ladder Belt: A belt worn around the waist with a hook that attaches directly to a rung.
  • Leg Lock: If a ladder belt is not available, a leg lock must be applied. The firefighter climbs one rung higher than the working rung, slides one leg through the rungs (above the rung they will stand on), and hooks their foot around the opposite beam or the rung below. This secures the firefighter, leaving both hands free to operate tools safely.
