The dangers from electricity are of shock, fire, burns and explosion, injury from involuntary reaction to otherwise harmless shock and, in the microwave and ultraviolet range, radiation damage.
Accidents involving electricity are often fatal.
Death can result from the passage through the body of an alternating current of only a few milliamperes in value. The population at large is generally well protected at work and at home by long established safety techniques. Earthing of metal work which could become live under fault conditions. Fuses or circuit breakers to protect equipment from excess current and, to allow safe isolation. Residual current circuit breakers.
