The minimum height of a barricade toeboard must be _______ inches?

The minimum height of a barricade toeboard must be 4 inches to effectively prevent tools, materials, or other debris from falling off elevated surfaces, which is crucial for maintaining safety in construction and installation sites. The 4-inch requirement is based on safety standards that provide a balance between ensuring adequate protection while still allowing for accessibility and movement around the work area.

This height is sufficient to act as a barrier, minimizing the risk of accidents. If the toeboard were lower than this, it would not adequately serve its purpose, potentially leading to hazardous situations. The regulations reflect best practices in safety management and are critical for protecting workers on the site.
