In a recent publication of Safey and Health magazine I found an interesting article in their Safety Tips.

The article was titled “Preventing arc flashes”. It covered the different types of measures that can be taken to minimize injury due to arc flash events. It also put them in a hierarchy of effectiveness as modeled by OSHA. The Hierarchy of Controls pyramid shown below shows the basic safety protocols in order of incresing effectiveness. Although Personal Protective Equipment (PPE), like arc rated clothing, is on the bottom, it does set the foundation as a level of safety insurance, should the other control measure fail or fail to be implemented. If the workers, potentially exposed to an electric arc flash, always wear their arc rated FR clothing, they can have some level of comfort that they will be protected should the other controls not be properly implemented or fail.
