When it comes to electrical safety in today's workplace, there seems to be some misconceptions. For instance, many people believe that arc flash can only be hazardous when working with high voltage or voltage above 600v. Statistics, however, say otherwise.
One of the most important factors in determining your hazard is to identify the magnitude and duration of the fault current for a particular piece of equipment. The combination of the maximum fault current that is available during an arc flash incident and the duration of time that the arc can sustain itself is critical to the severity of the injury that may result.
