For escape/entry operations, what is the approved ladder overlap?

• A. The ladder must extend at least 3 rungs above the sill.
• B. The ladder must extend at least 3 rungs (roughly 1 meter) above the sill.
• C. The ladder must extend at least 6 rungs above the sill.
• D. No overlap is required.

Answer: (B)

Ladder overlap above the window sill is essential for a safe transition during escape/entry operations. You want the ladder to extend at least three rungs above the sill, roughly one meter, so you have a solid handhold and a secure place to place your foot as you move from the window to the ladder and establish three points of contact. This minimum helps prevent slipping and gives you a reliable starting grip without delaying you with unnecessary extra length. Extending three rungs provides enough overlap for a confident pull onto the ladder, while more than that isn’t required for standard procedures and having no overlap would remove that critical handhold. So the approved overlap is at least three rungs above the sill, about one meter.
