Why you need an incident energy/arc flash analysis
Demand for high-efficiency electrical equipment is steadily increasing. With more electrical equipment to maintain and operate, workers are exposed to numerous hazards every day. One of those hazards is arc flash, or an arc blast, which can have devastating consequences. If there is an incident, the emotional and financial effects can be devastating. As illustrated in Figure 1, when you start to combine individual arc flash risks, you significantly increase the chances of an arc flash event.
In the United States, OSHA 1910.132 requires employers to access the workplace to determine whether hazards do or are likely to exist. OSHA references the National Electrical Code, NFPA 70E, and the IEEE standards for compliancy.
