Electrocution may occur as a result of domestic or industrial electricity or lightning strike. Adults are mostly likely to experience electrical injury in the workplace, while children are more at risk at home. There are approximately 1000 deaths worldwide every year from lightning strike (Auerbach 1995). Injuries may range from a transient, unpleasant sensation from contact with a low current to cardiac arrest from exposure to high voltage or current. The severity of electrical injury is also dependent on whether the current is alternating (a.c.) or direct (d.c.), magnitude of the energy delivered, resistance to current flow, pathway of current through the casualty and the area and duration of electrical contact (Lederer et al. 1999).
