To enhance the public’s safety awareness and preparedness, National Grid brought its live line demonstration trailer to Brockport Fire District’s Station Five on August 11 to demonstrate the dangers posed by live electricity wires, including downed wires and electrical contacts during weather events and emergencies. The live line demonstration trailer is a mobile training unit designed to provide hands-on electrical safety training for first responders, including firefighters, police, and EMTs.
Attendees saw examples of the powerful energy produced during emergency situations and gained an understanding of risks associated with such circumstances during storms. These include what happens when a tree hits a wire, when a downed wire hits a fence, and when the ground/water is electrified. There was also a demonstration on how to safely connect a generator.
Downed power lines and wires create danger for anyone who approaches. National Grid says you should always assume power lines are live even if they aren’t sparking or humming. If you see a downed wire, keep a distance of at least 30 feet and call 9-1-1 to report it.
Downed trees could have wires caught in them, and wood can conduct electricity when wet. Avoid coming in contact with branches or trees if they have fallen. If you are unsure if a wire caught in a tree is an electric wire, contact your power company.
Water is a natural conductor of electricity, and a downed line in a puddle or flooded area can electrify it, creating a deadly hazard. Even non-conducting materials like cloth or wood can conduct electricity when wet.
Also, never touch a person in contact with a downed wire because human bodies can conduct electricity, which means the electricity will be passed on to you.
Safety should be your first priority when you see a downed wire. Call 9-1-1 to report it immediately and keep yourself and others away from the scene.
