What is the required rung length for ladders on scaffolding?

The required rung length for ladders on scaffolding is between 11.5 and 16.75 inches. This range ensures that the rungs provide sufficient space for safe foot placement, promoting stability and reducing the risk of slips or falls. Adequate rung length is critical for maintaining worker safety, especially on construction sites where scaffolding is used frequently.

Selecting rungs within this specified length range ensures compliance with safety standards and regulations, which are designed to protect workers from workplace hazards. Scaffolding and ladder safety regulations often stipulate that ladder rungs be designed to accommodate a range of foot sizes while also considering the durability and construction of the ladder itself. This reduces the risk of accidents, as workers can safely navigate up and down the scaffolding.

While other options may have lengths that seem close, they fall outside the acceptable range set by safety organizations and regulations, which can lead to potential safety hazards on the job site. A thorough understanding of these specifications is crucial for anyone engaged in construction work or site surveillance where scaffolding is present.
