If an incomplete scaffold is left overnight, which is a recommended risk control?

Installing, isolating, and barricading access to an incomplete scaffold overnight is essential for ensuring safety at the worksite. This control measure effectively prevents unauthorized access, thereby reducing the risk of accidents and injuries that could occur if individuals unknowingly enter an unsafe area.

Barricading serves as a physical barrier, clearly indicating that the area is not safe for entry. It deters unauthorized personnel from accessing the scaffold and minimizes the chance of falls or mishaps due to incomplete or unstable structures left unattended.

While clearing the area, installing surveillance cameras, and informing nearby residents might enhance safety, they do not directly manage access to the scaffold itself. Simply clearing the area may not prevent people from entering, and surveillance does not prevent accidents but merely records them. Informing nearby residents, while a good communication practice, does not provide a physical barrier to protect against potential hazards. Therefore, the most effective risk control in this scenario is to remove, isolate, and barricade access to ensure no one can inadvertently put themselves in danger.
