Arc Flash Risk Assessments

When are they needed, and what do they accomplish?

Every day around the world, at least five non-deliberate, major explosions with temperatures more than three times the heat of the sun and sound waves louder than a jet at takeoff happen to electrical equipment.

Each explosion causes both major damage to equipment and personnel injuries, with direct costs of each incident of more than $80,000 and indirect costs, such as worker’s compensation claims, electrical outages, and equipment damage, easily exceeding four times that amount. This creates a total economic burden of millions of dollars each year, not to mention the cost to human life.

In this Salas O'Brien white paper, we discuss how electrical system studies can prevent costly arc flash explosions.
