Guardrails are installed primarily to achieve which of the following purposes?

Guardrails are primarily installed to enhance safety by serving as a physical barrier that helps prevent falls and serious injuries, particularly in environments where there is a risk of drops or accidents from elevated surfaces. The design and placement of guardrails aim to protect individuals working at heights or near hazardous edges, ensuring they remain secure and reducing the likelihood of severe incidents.

While aesthetics, preventing spills, and enhancing equipment life may be considerations in different contexts or applications, the primary function of guardrails is to safeguard individuals. A well-designed guardrail system is crucial for minimizing risks associated with working at heights, thereby fulfilling the essential safety purpose that justifies its implementation.
