What Are Support Requirements for Fixed Ladders?
Fixed ladders are commonly found in many industrial and commercial settings, providing access to elevated areas such as rooftops, platforms, and mezzanines. To ensure the safety of workers using these ladders, there are specific support requirements that must be met. Here is an overview of those requirements:
1. Wall-Mounted Ladders: Wall-mounted fixed ladders must be securely fastened to the structure with brackets or other suitable means. The ladder should be attached at intervals not exceeding 25 feet vertically.
2. Free-Standing Ladders: Free-standing fixed ladders should be securely anchored to the ground or a suitable base. They should also have stability devices at the top to prevent movement.
3. Rungs and Steps: The rungs or steps of fixed ladders should be uniformly spaced, with a minimum clear width of 16 inches. They should be parallel, level, and free from any projections that could cause injury.
4. Clearance: Fixed ladders must have a minimum distance of 7 inches from the back of the ladder to the nearest permanent object. This ensures that workers have enough space to climb safely.
5. Side Rails: Fixed ladders should have side rails that extend at least 42 inches above the top landing or platform. The side rails help prevent falls and provide additional stability.
6. Access: Fixed ladders should have a clear and unobstructed path of access. There should be no objects, equipment, or structures that could hinder a worker’s ability to climb or descend safely.
7. Maintenance: Fixed ladders should be inspected regularly to ensure they are in good condition. Any defects or damage should be repaired promptly to maintain their structural integrity.
