Arc Flash: From Prediction to PPEDownload Now
Thousands of workers are admitted to burn centers each year for arc-flash-related injuries. The past decade has seen tremendous progress made in protecting workers against the heat energy associated with arc flash. One major area of improvement has been the steps taken to get workers into safer clothing. The arc rating system, developed in ASTM 1959, and the development of the predictive equations identified in NFPA 70E and IEEE 1584 have been instrumental in this effort. This white paper explains the directional nature of arc development and test setups, as well as heat measurements with alternate test configurations and their effects on PPE.
