What is the height requirement for guardrails?

The requirement for guardrails is set at 42 inches in height. This standard is established to ensure the safety of workers on elevated surfaces, such as scaffolding or open-sided platforms, by providing an adequate barrier that helps prevent falls. A height of 42 inches strikes a balance between being high enough to reduce the risk of falling over the edge and low enough to allow for visibility and ease of use for workers, such as being able to see over the top of the rail.

In addition to the height, guardrails are typically required to be constructed of materials that can withstand specific loads without collapsing or breaking, further enhancing safety for those working in elevated conditions. The height of 42 inches is widely recognized and adopted across various safety regulations, making it a critical aspect of workplace safety practices in the construction industry.
