If scaffolders need to work closer than the minimum safe distance from powerlines, what is one required action?

When scaffolders need to work closer than the minimum safe distance from powerlines, having the electrical power disconnected is essential for ensuring safety. This action significantly reduces the risk of electrocution or electrical hazards while working near live powerlines. Disconnecting power eliminates the possibility of accidental contact or arcing, which can result in serious injuries or fatalities.

While other actions, such as obtaining a permit, using insulated scaffolding, and conducting a risk assessment, are important components of overall safety protocols, they do not directly mitigate the immediate danger posed by working near live electrical power. Disconnecting the power is a definitive action that addresses the hazard right at its source, thus prioritizing the health and safety of the workers involved.
