High Voltage, when referring to electric power transmission, is anything over 35,000 volts. At this voltage, combined with an average amperage, even a second of contact could do major damage to fragile human tissue. In addition, this kind of voltage, when pushed through a conductor, can cause burns and fuse metals and other materials together.
Voltages of greater than 50 V are capable of producing heart fibrillation if they produce electric currents in body tissues which happen to pass through the chest area. The electrocution danger is mostly determined by the low conductivity of dry human skin. If skin is wet, or if there are wounds, or if the voltage is applied to electrodes which penetrate the skin, then even voltage sources below 40 V can be lethal if contacted.
Accidental contact with high voltage will usually result in severe injury or death. This can occur as a person’s body provides a path for current flow causing tissue damage and heart failure. Other injuries can include burns from the arc generated by the accidental contact. These can be especially dangerous if the victims airways are affected. Injuries may also be suffered as a result of the physical forces exerted as people may fall from height or be thrown considerable distance.
It’s imperitive that all employees follow proper safety precautions when working near or with high voltage equipment. We’ve developed a decal to help create awareness of these situations in the SD007-08 5″ x 3″ Vinyl Decal.
