Eric’s story

Eric’s story is a two-minute video about a young man who survives an electrical incident. Eric and his friends were out one night when they ended up somewhere they weren’t allowed to be. A split second of poor judgement changed Eric’s life forever. Some key details from his experience include: 

• Eric found himself close to a 12,000 volt main line going into a transformer.
• The electricity arced and entered through the left side of Eric’s head and exited his left wrist.
• Electricity can jump.
• It all happened so fast.
• It was a split second of poor judgement.
• A lifetime of change started there.
• There needs to be a respect for electricity.

PSAs

Developing a concept for a Public Service Announcement embraces the new curriculum model of “Know–Do–Understand” and is a way to honour students’ voice and choice. Creating a digital PSA demonstrates a logical sequencing of ideas, connects appropriate content to the overarching message, and exudes a high quality and depth of learning. The Core Competencies of Personal Awareness, Social Responsibility, Communication, Critical Thinking and Creative Thinking are all supported in this activity. 

Science of electricity  

Electricity is powerful and can be dangerous. The more students know about electrical safety and responding to emergencies at home, in the community and in the workplace, the better informed they’ll be when making decisions.      

Electricity seeks the easiest path to the ground and will travel there through any conductive material. The human body conducts electricity and if we get between electricity and the ground or something touching the ground, electricity will flow through us. 

Electricity travels very quickly – approximately 300,000 km per second. You aren’t given any warning or time to react. 

Down. Danger. Dial.

A downed line may be on the ground or caught in a tree. Wherever it’s landed, it can be a danger to yourself and others. Stay at least 10 metres (the length of a yellow school bus) away from the downed line and call 911 as soon as you can. Emergency services dispatch a team immediately to secure the area and will contact BC Hydro right away. For more information, go to bchydro.com.

Touch and step potential

Touching anything connected to live electricity can provide a path to ground (e.g. touching a ladder that becomes energized by electricity creates a path to ground through the person). This is called touch potential.

Electricity moves from high to low concentrations and spreads away from a point of contact on the ground in concentric circles. If a person is standing with one foot on an energized piece of ground and the other foot on a less energized piece of ground, electricity will move through the person. This is called step potential.

If you find yourself near a downed power line, you need to shuffle away from the electrically charged ground until you are at least 10 metres away. Shuffle with your feet close together so that the heel of the front foot doesn’t pass the toes of the back foot.

Electrical injuries

Injuries can occur through direct contact with electrical energy or when electricity arcs (jumps) through the air to a person who is grounded. High-voltage contact burns can damage internal tissues while leaving only very small injuries on the skin. Muscle contractions, or a startled reaction, can cause a person to fall from a ladder or height, causing serious injuries. 

Electrical contact can cause electric shock, which prevents a person from moving to disconnect the electricity, and can cause serious internal injuries, burns or electrocution. Electrocution is the term used for a death caused by electrical contact. High voltage electricity can move through all types of materials including metals, wood, rubber and soil. No matter the urge to help someone, don’t touch someone who is being shocked. Call 911 and wait until BC Hydro can isolate and turn off the power.

Power lines

Always look up and look down. Be aware of overhead and underground power lines. 

Overhead wires entering houses and buildings aren’t insulated and therefore can’t protect you from an electric shock. You don’t have to touch a power line to be shocked or electrocuted; if you come within three metres of a power line, the energy can arc (jump) towards you and take a path to the ground through your body. Remember this if you are using a ladder, painting, climbing trees or cutting branches. Stay back at least three metres from any power line.

If you don’t see the power lines above you, they are buried underground. Call BC 1 Call (1-800-474-6886) before digging to find out the location of underground electricity, gas or service lines and avoid them. 

Power outages

Power outages can be caused by power lines falling to the ground. Remember to stay back at least 10 metres from a downed power line and call 911.

Prepare for a power outage by developing a plan with your family. Make a list of local emergency contact numbers and purchase or prepare an emergency kit. Never use a portable generator indoors because carbon monoxide gas can build up and lead to death. All workplaces should have an emergency plan. Make sure you’re familiar with it. 

Power cords and outlets

• Don’t overload circuits. This can cause short circuits and possibly a fire. If multiple connections are required, use a properly rated power bar. 
• Never use cords or plugs that show signs of wear or damage. They can cause shocks or fires.
• Don’t use a two-pronged extension cord outside. 

Water and electricity

• Keep all electrical cords away from heat and water.
• Never use electrical tools or appliances near water.
• Never use an electric lawn mower when it’s raining or on wet grass.
• Keep plugged in devices away from swimming pools or wet surfaces.
