What is the minimum height for a toeboard on the guardline as per ASME B30.23?

The correct choice indicates that the minimum height for a toeboard on the guardline, as outlined in ASME B30.23, is 3 1/2 inches. This requirement is established to ensure safety on construction sites and other environments where elevated work is performed.

Toeboards serve a critical function by preventing tools, materials, or large objects from falling off elevated surfaces and potentially injuring personnel below. The specified height of 3 1/2 inches is deemed sufficient to act as a barrier, helping to mitigate the risk of falling hazards. This height balances the need for safety with practical considerations regarding the design and functionality of work surfaces.

Understanding this regulation is essential for compliance and promoting a safe working environment, reinforcing the importance of following established guidelines in occupational safety standards.
