What Does Electrical Shock Mean?
An electrical shock is a physical reaction to electrical currents passing through the body. They range from almost imperceptible reactions to highly dangerous shocks that can affect the heart muscle and cause tissue damage. In severe cases, this may be fatal.
The prevention of electrical shocks is accomplished through shock hazard analysis. In general, fatal or serious shocks are most often sustained by personnel who fail to comply with safety regulations surrounding the de-energization of electrical components prior to maintenance activities. Arc flash hazard analysis determines how electrical equipment will respond in the event of a short-circuit. Arc blast hazard analysis seeks to identify the circumstances in which a blast could take place as well as the blast pressure it will create.
