What is the minimum wood thickness required for overhead protection on a temporary working platform?

The minimum wood thickness required for overhead protection on a temporary working platform is indeed 2 inches. This thickness is established to ensure adequate structural integrity and safety for workers below. Wood of this size can effectively withstand potential impacts from tools, materials, or equipment that may fall from above during construction or maintenance activities.

Using wood that is 2 inches thick provides a balance between weight, manageability, and strength. Thicker materials, while potentially offering better protection, could be cumbersome to work with and increase the overall load on the platform. Hence, regulations incorporate a minimum thickness that ensures safety while allowing for practical usability.
