Did you know that standing or walking near a downed power line can be just as dangerous as touching the line itself? This type of hazard is called step potential, and should be in the front of your mind if you come across any fallen power equipment.
What is step potential?
Step potential is the danger present when two parts of your body (usually your feet) are in two different voltage zones. This difference in voltage causes the current to run through you and shock you, which can be fatal.
When do I have to worry?
Whenever you see downed or malfunctioning power equipment, you need to worry about step potential. Broken power equipment can feed electricity directly into the ground, charging the earth beneath your feet. If you have one foot closer to the source of the charge than the other, you can be shocked.
What should I do if I see a piece of broken equipment?
If you see a downed power line or other piece of broken equipment, be sure to stay at least 10 feet away. Call Eversource or 911 and keep your distance until they make the area safe for everyone.
What if I’m in an accident close to a piece of broken equipment?
If you’re in an accident with a car or other vehicle near a downed power line, stay in the vehicle. Eversource or a first responder will tell you when it’s safe to get out. Keep in mind, it is OK to use your cell phone from inside your car.
What if I have to get out of the car?
If there’s a fire or other emergency forcing you to exit the vehicle, there is a special procedure to follow when moving to safety:
- Open the door and and jump clear of the car. Never have one foot touching the ground and the other in the car. Land with both feet together.
- Immediately shuffle or hop away from the vehicle. Keep your feet as close together as you can, so the voltage stays the same.
- Once you are more than 10 feet away from the vehicle, call Eversource or 911 immediately and report the emergency.
