What is the required strength of a handrail according to safety standards?

The required strength of a handrail, according to safety standards, specifies that it must withstand a force of 200 pounds applied within 2 inches of the top edge. This requirement is in place to ensure that handrails provide adequate support and stability for individuals who may rely on them for balance or leverage, especially in construction environments where safety is paramount.

Applying this force within the specified distance ensures that the handrail is strong enough to resist not only typical pulls or pushes but also unexpected forces that could occur in a construction setting, such as someone leaning heavily on the rail or bumping into it. The focus on the top edge also reflects the practical use of handrails, as this is typically where most users will make contact.

In contrast, the other options do not align with the established safety standards for handrails. Options that specify different poundage either below or above the 200-pound requirement do not reflect the strength needed to ensure safety in construction scenarios. The choice of applying the force at any point greater than 2 inches from the top might not adequately account for the most likely points of strain experienced during use.
