Arc Flash Incident Energy Analysis
Five to ten victims of arc flash hazards are hospitalized daily; and as many as 80% of all electrical injuries are caused by arc flash. So, what is this powerful force that can change a life in an instant? Arc flash is often described as a short circuit through the air. It is a very hazardous situation associated with an explosive discharge of energy caused by an electric arc. Electric arcs can occur due to poor electrical contact or failed insulation. Such situations allow the passage of substantial amounts of current through the vaporized terminal material - usually metal or carbon. The arc flash comes from the heat and the light produced by the arc.
To determine the potential arc flash associated with exposed energized circuits, an arc flash incident energy analysis
is required. This analysis calculates the intensity of the arc flash at various distances so a determination can be made regarding flash protection boundary distances and the type of PPE necessary while working in the area of the threat. Arc flash needs to be taken very seriously. Call us
