Don't go near downed lines, and please report the problem to OPPD as quickly as possible. Until repair crews arrive, please watch the line at a safe distance, if possible, and alert others who may come by.
If clean-up work is necessary following a storm or other event, please make sure you watch out for any power lines on the ground or overhead. Make sure there aren't any downed lines tangled in fallen tree limbs or debris that you're about to clear.
In fact, treat every downed power line as a live high voltage wire, and stay away.
If you're working above the ground, for example, removing damaged branches from a tree or checking for roof damage, make sure there aren't any overhead power lines near your work area.
