What is the first step to take if work is required inside the mandated electrical exclusion zone?

The first step to take if work is required inside the mandated electrical exclusion zone is to have power isolated or insulated. This is a critical safety measure because the exclusion zone is designated to protect individuals from electrical hazards. By ensuring that the power is either fully disconnected or adequately insulated, the risk of electric shock or electrocution is significantly reduced.

Having power isolated means that the electrical source is turned off, while insulation helps to prevent accidental contact with live parts. This immediate action establishes a safe working environment before any other safety measures or assessments are implemented.

While other actions, such as installing safety barriers or conducting a risk assessment, are important for overall safety, they are secondary to first ensuring that there is no active electrical hazard present. Similarly, notifying local authorities may be a procedural step, but the safety of the workers in the exclusion zone must be prioritized above all.
