Basics Safety |
|
It's the volts that jolts and the mills that kills. (milliamps)
Most people have experienced a static electric shock.
These are not dangerous because they contain so little energy even though the voltage might be as high as 10 000 Volts.
A high current shock at a lower voltage can be much more dangerous.
Effects of the shock ...
Low to moderate voltage electric shocks are rarely fatal if correct, quick action is taken.
Higher voltages might cause fatal damage almost instantly.
Rescue and First Aid ...
Some electronic components contain chemicals that are harmful to the environment or to human health.
If the victim survives the electric shock, they can also be badly burned. Clothing can become super-heated and should be removed to reduce burning. The best place to survive lightning is in a Faraday cage (a metal box). Cars and aircraft make good Faraday cages and make safe refuges. The people inside a car were completely unhurt when a strike expolded all four tyres and caused other exterior burning.
