Which of the following locations are guardrails required?

Guardrails are specifically required on scaffolds to provide safety and prevent falls while workers are elevated. Scaffolds, being temporary structures designed to support workers and materials during construction or maintenance tasks, present significant fall hazards. The establishment of guardrails on scaffolds is essential to ensure that workers are protected, as they help to retain individuals within the safe work area and act as a physical barrier against falling off the edge.

In contrast, while rooftops, lobbies, and hallways may have their own safety requirements, the explicit need for guardrails is specifically emphasized in regulations governing scaffolding operations to address the unique risks associated with working at heights. The Occupational Safety and Health Administration (OSHA) mandates that guardrails be installed on scaffolds when the work surface is more than a certain height above the ground or lower levels to ensure the safety of workers.
