Scaffolding safety requires which features?

• A. Guard rails, mid rails, and toe boards
• B. Only guard rails
• C. Only mid rails
• D. No rails are required

Answer: (A)

Scaffolding safety relies on a complete edge and falling-object protection system. Guard rails provide a barrier along the top edge, preventing a worker from stepping off. Mid rails fill the space between the guard rail and the platform so a person can’t slip through. Toe boards run along the platform edge to stop tools and materials from tumbling off and hitting people below. Together, these three features address both fall hazards and falling-object hazards, which is why this combination is required. Relying on only guard rails leaves gaps at the sides; relying on only mid rails omits top-edge protection; and having no rails at all is unsafe.
