As you approach a downed power line, look for the ends of the line. They may be hidden by objects or foliage.
Stay clear of anything a downed line may be in contact with, such as fences, vehicles, trees, utility poles and other wires. A downed line can energize these objects.
Be alert for multiple hazards. If there is one power line down, there may be others. Don’t let the most obvious hazard distract you from other potential hazards in the area.
Maintain a safety perimeter around downed power lines until you receive the all-clear from utility personnel:
Keep yourself, your vehicles and equipment and the public at least 30 feet away from downed distribution lines and at least 100 feet away from downed transmission lines.
All safety clearances given here are minimums; always use the maximum possible distance.
Be extremely cautious when using water to fight fires near downed power lines. Follow the 30/30/100 rule: Stay at least 30 feet away from energized objects, and use a 30-degree fog pattern at 100 psi—NEVER a straight stream.
