As many as 80% of all electrical injuries are caused by burns resulting from exposure to energy released from an arcing fault. Typically, exposed workers receive second and third degree burns that are often fatal.
NEC Article 110.16 Flash Protection requires labeling on switchboards, panel boards, motor control centers and industrial control panels so that electrical workers are made aware of the potential hazards and can take appropriate action, (e.g. safe work practices, PPE, etc.) In some cases this may require an arc-flash study to determine the intensity of the arc flash at various distances.
EESCO performs these arc-flash studies using calculation methods to determine the incident energy in cal/cm2 for a distance from an electric arc. Based on the results of these studies, reports (and labels) can be applied to appropriate equipment, which clearly indicate the class of PPE required at various distances. This study is typically performed in conjunction with the short circuit analysis and protective device coordination study discussed above.
