Which action is taken as the last step in responding to an electrical incident?

In the context of responding to an electrical incident, calling for emergency assistance and beginning CPR represents a critical and immediate life-saving measure. This action becomes the priority when someone has sustained an electrical shock or is in a state of medical emergency. The focus at this stage is to ensure that professional medical help is on the way while also providing necessary first aid to the victim.

Promptly calling for emergency assistance ensures that trained professionals can arrive quickly to provide further medical attention that may be required based on the victim’s condition. If the victim is unresponsive and not breathing, initiating CPR is vital in maintaining blood flow and oxygenation until higher-level medical care arrives, significantly increasing the victim's chances of survival.

While other actions like moving oneself and the victim to safety, verifying test instrument operations, and assessing surrounding hazards are important components of the response process, they typically occur prior to the emergency response step. The urgency of supportive care and the involvement of emergency services takes precedence when dealing with potential life-threatening situations following an electrical incident.
