Ladder Placement at Windows
Ladder Placement at Windows
Place the ladder in the center of the window so that the ladder tip is even with the window sill for stability and safety.
Reasoning for Ladder Placement

Study Notes
Ladder Placement & Selection
- Proper ladder selection and placement are critical for effective ladder use at an emergency scene
Ladder Placement at Windows for Rescue
- Position the ladder in the window's center so the ladder tip aligns with the windowsill, regardless of window width; for sills projecting from the wall, wedge the ladder tip underneath for added stability
- Aligning the ladder tip with the windowsill allows firefighters and civilians to stay low, avoiding heat and smoke, when moving onto the ladder; the ladder bail technique learned during Rapid Intervention Training allow firefighters quick exits; also allows firefighters to help assist or lift civilians over the sill
Second Ladder Placement
- A second ladder can be placed beside the first, enabling a second rescuer to assist in victim rescue, regardless of window size or first ladder placement; place the second ladder approximately one foot away from the first
Access to the Roof
- When placing ladders to the roof, extend them about five rungs above the coping
- Ladder extensions provide a hold for firefighters to test roof stability before bearing weight and allow the roof team can see the ladder from any point on the roof (unless there are obstructions like smoke)
Ventilating Windows
- Place the ladder on the windward side of the window with the ladder tip about even with the top of the window when ventilating from a ladder
- This allows firefighters to vent the upper window portion with the most dense smoke and heat
- The positioning also ensure glass falls away and that smoke and hot gases blow away
- If rapid window ventilation is needed, raise the ladder tip to the window's top section, break the glass by dropping the ladder tip into the window, step away, and then move the ladder to the window's windward side to clear remaining glass shards; This is a dangerous maneuver due to falling glass
- After either ventilation method, firefighters should lower the ladder and reposition it at the sill for rescue
Additional Tips for Ground Ladder Use During Rescue
- When a ladder is placed firefighters should advise their location; ex. "A ladder is in place, 2nd floor, sector 2" so others are aware of its placement
- When climbing the ladder, the rescuer should wear an SCBA to assist patients
- Ground ladders must always be heeled
- When using a 50' Bangor, both tormentor poles should be used on each side for support
Selecting the Right Ladder
- Residential floors typically measure 8-10 feet in height from floor to floor, with a 3-foot distance from the window sill to the floor. Commercial building floors are about 12-feet high with a 4-foot sill distance
- A ladder's reach is less than its full length due to angle placement; reach is about a foot less the amount for ladders under 35 feet and about two feet less for ladders over 35 feet
Extensive Method of Ground Ladder Selection
- To determine the correct ground ladder to use, factor in the information provided
Ladder Selection Guide
- Residential and commercial buildings may require different ladders as residential dwellings can have peaked or flat roofs, while commercial buildings typically have flat roofs
- A quick method for ground ladder selection involves counting the stories to be reached and using this number as the first digit of the required ladder size; consider the roof an additional story; using this method, if the window is on the 3rd story, select a 35' or 38' ladder
- The most versatile ladder on the Chicago Fire Department is a 35' / 38' ladder
Before Raising or Lowering Ladders
- Always check for power lines and other hazards overhead
