What should an operator do if a mobile crane strikes a power line?

1. Exit the crane immediately

2. Stay in the crane until emergency crew arrives

3. Call emergency services from the crane

4. Shut down the crane's power

The correct answer is: Stay in the crane until emergency crew arrives

When a mobile crane strikes a power line, the safest course of action is for the operator to remain in the crane until emergency services arrive. This recommendation is based on several crucial safety considerations. When a crane makes contact with a power line, it can create a dangerous situation where the crane becomes electrified. Exiting the crane can expose the operator and any nearby personnel to the risk of electric shock or electrocution. Staying inside the crane, which acts as an insulating barrier, minimizes that risk while waiting for professional help to assess the situation and safely remove the crane from the power line. Furthermore, attempting to call emergency services from within the crane provides a direct line of communication with external help while ensuring that the operator remains in a protected environment. It is vital for operators not to attempt to shut down the crane or conduct any further actions that could put themselves or others in jeopardy. By remaining in the crane until trained emergency responders arrive, operators significantly reduce their risk and ensure a safe resolution to the dangerous incident.
