Description
Electrically powered equipment can pose a significant hazard to workers, particularly when mishandled or not maintained. Many electrical devices have high voltage or high power requirements, carrying even more risk.
The major hazards associated with electricity are an electrical shock, fire and arc flash. Electrical shock occurs when the body becomes part of the electric circuit, either when an individual comes in contact with both wires of an electrical circuit, one wire of an energized circuit and the ground, or a metallic part that has become energized by contact with an electrical conductor.
The severity and effects of an electrical shock depend on a number of factors, such as the pathway through the body, the amount of current, the length of time of the exposure, and whether the skin is wet or dry. Water is a great conductor of electricity, allowing current to flow more easily in wet conditions and through wet skin.
The effect of the shock may range from a slight tingle to severe burns to cardiac arrest. The chart below shows the general relationship between the degree of injury and the amount of current for a 60-cycle hand-to-foot path of one second's duration of the shock. While reading this chart, keep in mind that most electrical circuits can provide, under normal conditions, up to 20,000 milliamperes of current flow.
Top 10 Rules for Electric Safety
To play it safe around your home, just remember the rules for using electricity the right way.
1. DON'T plug a bunch of stuff into one outlet or extension cord.
It could damage the electrical system in your house or even cause a fire.
2. DO ask grown-ups to put safety caps on all unused electrical outlets.
Covering outlets will also help save energy by stopping cold drafts.
3. DON’T yank an electrical cord from the wall.
Pulling on a cord can damage the appliance, the plug or the outlet.
4. DO make sure all electric cords are tucked away, neat and tidy.
Pets might chew on electrical cords, and people might trip and fall.
5. DO ask a grown-up for help
when you need to use something that uses electricity.
6. DO look up and look out for power lines before you climb a tree.
The electricity can go right through the tree branch - and right through you!
7. DON'T ever climb the fence around an electrical substation.
If a ball or pet gets inside the fence, ask a grown-up to call the electric company - they'll come and get it out for you.
8. DO remind your mom or dad to watch out for power lines
When they're using a ladder, chainsaw or other outdoor equipment.
9. DO keep electrical stuff far away from water.
Most electrical accidents around the house happen when people use electricity near water.
10. DON’T fly a kite near power lines.
The kite and the string may conduct electricity – sending it right through you to the ground.
