The following are some important facts about electricity.
Basic facts about electricity you should know…..
Electricity seeks the easiest and shortest path to the ground. When people or objects come too close to, or touch an electrical wire, they can become a part of the electrical circuit which can result in an instant flow of electricity through them to ground.
The flow of electricity through the human body can kill. Less than one ampere of electricity can burn, severely injure or cause death. Electricity is fast, electricity travels at approximately 299,330 km per second. That leaves no room for mistakes. Never put yourself into electricity’s path.
"Conductors" conduct electricity quickly and in large amounts. All metals, waters, humans and even non-metallic materials (trees, ropes etc.) can conduct electricity depending on their moisture content and surface contamination. Caution needs to be applied.
When birds land on wire they don’t get electrocuted because they don’t represent a path to ground. Electricity wants nothing more than to go to ground and will always do so by the easiest most direct way. A bird on a wire and not touching another wire or the ground ,doesn’t provide a path of current,and electricity has nowhere to go but back to the wire hence ,the bird does not get electrified.
Many overhead power lines are insulated but only to a level to prevent problems from incidental tree contact. They are usually not fully insulated to prevent injury to people. So they are not safe to touch.
All ladders should be kept away from overhead power lines. No matter what the ladder is made of, if it’s wet or can get wet, it represents a potential hazard. Even if the ladder isn’t metal, it isn’t safe to rest on power lines. Depending on how far away your ladder and you are from the line, electricity can jump and often does when a potential conductor like a metal ladder comes within a certain proximity. Be safe, and keep well away from overhead power lines.
All electrical equipment installed by the utility company to help deliver electricity from the high voltage lines near your neighborhood , should be marked with warning labels as an electrical hazard to keep everybody away. The Warning labels shall be visible and must be designed and tested to communicate a sense of danger even to children who are too young to read.
