Electrical Safety Measures - Arc Flash Risk Assessment & 40 cal/cm2 Myth

Qualified Electrical Workers (QEW) need to complete an Arc Flash Risk Assessment related to an energized electrical work task that has been assigned to them.

What does this mean? How do they get the hazard information they need? Is there an Equipment Label, and is it correct? If there is NO Equipment Label what does the QEW have to do? Does the QEW understand that arc-rated PPE is defined by its Arc Thermal Performance Value (ATPV)? Is the Arc Flash Boundary distance understood? Do the workers keep their face and torso at the “Working Distance” when they perform the work task that may expose them to an arc flash? Does the QEW follow a company’s defined policies and practices when performing a work task that may expose them to an arc flash?
