If your machine contacts overhead or underground power lines, what should you do?

1. Get off the machine immediately

2. Stay on the machine and warn others

3. Try to move the machine

4. Disconnect the power line if possible

The correct answer is: Stay on the machine and warn others

Staying on the machine and warning others is the correct action to take if your machine contacts overhead or underground power lines. When a machine comes into contact with power lines, there is a significant danger of electric shock or electrocution. By remaining on the machine, you minimize the risk of becoming a ground path for electrical current, which can happen if you exit the machine and touch the ground while still in contact with the power lines. Additionally, warning others to stay away is crucial because they may be unaware of the danger and could inadvertently put themselves at risk. This protocol is vital to ensure the safety of everyone in the area until professional help arrives, such as utility workers who can safely assess and handle the situation. Other actions, like trying to move the machine or disconnecting the power line, could lead to further danger. Exiting the machine may expose the operator to electric shock. Therefore, the recommended procedure emphasizes remaining in the machine and alerting others until the threat has been resolved.
