Arc Flash

Arc Flash Hazard Analysis

An arc flash is the result of a rapid release of energy (light and heat) due to an arcing fault between electrical conductor(s) and another electrical conductor(s) or ground with enough electrical energy to cause damage or fire, and injury. During an arc fault air becomes the conductor. A massive amount of energy discharges during the arc flash or blast. This energy burns the conductors, vaporizing the copper and thus causing an explosive volumetric increase, the arc blast. This explosion propels deadly shrapnel and molten metal as it dissipates. This rapid release of energy can cause debilitating burns, other injuries and even death. Without an Arc-Flash Hazard Analysis, employers cannot properly protect their personnel from arc-flash.

The Arc Flash Hazard Analysis identifies the levels of incident energy throughout the system.

Consider your building. Have you completed an ArcFlash Hazard Analysis for the facility? Do you have a defined electrical safety program and proper training and PPE for your employees? Does your electrical equipment have warning labels that comply with NFPA 70E, OSHA, or ANSI Z 535? We can help. SSM supports numerous clients by performing comprehensive electrical distribution and equipment assessments; conducting short circuit analysis, time current coordination studies and identifying Hazards.
