What safety feature is required for rolling scaffolds?

The requirement for guardrails on rolling scaffolds is based on the need to protect workers from falling off the edges while working at height. Guardrails serve as a physical barrier, providing stability and support to individuals using the scaffold. They help prevent accidents by reducing the likelihood of a worker losing their balance or stepping off the edge, which is crucial in maintaining safety standards in construction and maintenance environments.

Guardrails are typically required to be a certain height and may include toeboard features to prevent tools or materials from falling off, further enhancing safety. While other options, such as safety nets, stabilizers, and safety harnesses, play important roles in various contexts of scaffolding use and fall protection, the specific requirement for guardrails addresses the immediate risk of falls from scaffolds, making them essential safety features in these working situations.
