What is the purpose of guardrail systems on construction sites?

The purpose of guardrail systems on construction sites is primarily to protect against falls from elevated surfaces. These systems are a critical safety measure designed to prevent workers from accidentally falling off edges, such as roofs, balconies, or other elevated work areas. Guardrails create a physical barrier that significantly reduces the risk of injury or fatalities resulting from falls, which are among the most common hazards in the construction industry.

While other choices may have some relevance to workplace safety or site organization, they do not encompass the fundamental role of guardrails. For example, using guardrails to support scaffolding does not reflect their main function; they are not intended as structural supports. Similarly, aesthetic purposes are not a consideration in the design and implementation of guardrail systems, which prioritize safety over looks. Finally, marking work boundaries is typically managed through other types of safety measures and signage rather than relying on guardrails.
