What is the minimum height at which a ladder should extend above a landing?

The minimum requirement for a ladder to extend above a landing is to extend at least 3 feet above the landing. This standard is aimed at providing adequate support and safety for individuals as they transition onto or off of the ladder. When a ladder extends this height above a landing, it offers a stable handhold, reducing the risk of falling or losing balance. This extension is particularly critical in preventing accidents during ascent and descent, where the potential for slips is heightened.

By ensuring that a ladder extends a sufficient distance above the landing, workers can safely grab the ladder for support as they step on or off. This safeguards against sudden shifts in weight or unexpected movements that could lead to injury. The established safety standard recognizes the importance of having a reliable point of grip to maintain stability, which is essential for safe ladder use in various work environments.
