Guardrail systems shall be capable of withstanding, without failure, a force of at least ___ pounds applied within 2 inches of the top edge, in any outward or downward direction at any point along the top edge.

The correct answer is based on OSHA regulations regarding guardrail systems, which are crucial for ensuring safety in work environments where there is a risk of falling. According to OSHA standards, guardrail systems must withstand a force of at least 200 pounds applied within 2 inches of the top edge in any outward or downward direction at any point along the top edge. The force requirement is in place to ensure that the guardrail can effectively prevent falls, which are a significant hazard in many construction and maintenance contexts.

This standard is designed to provide a barrier that is adequately sturdy, addressing both the durability of the materials used and the potential forces that could be exerted in various scenarios. Understanding this requirement is vital for contractors to ensure compliance with safety regulations and protect workers on site.
