Arc Flash Forum View topic - ARCAD performance

15/2/2016· In fact a study has been done that shows that "dumb luck" (not doing anything about arc flash) done by some folks at Dupont based on about 30-40 cases has a serious injury rate of 100%. If you just use the tables without the engineering calculations then based on an older edition of the tables (the 2015 version is much improved) there is a 50% chance of avoiding serious injury.
