IEEE 1584-2018 is an update to IEEE 1584-2002 and was developed to help protect people from arc-flash hazard dangers. The predicted arc current and incident energy are used in selecting appropriate overcurrent protective devices and personal protective equipment (generally abbreviated as PPE), as well as defining safe working distance. Since ...

[citation needed] Higher voltages can cause a spark to jump, initiating an arc flash without the need for physical contact, and can sustain an arc across longer gaps. Most powerlines use voltages exceeding 1000 volts, and can be an arc-flash hazard to birds, squirrels, people, or equipment such as vehicles or ladders.
In the mining industry, non-contact electrical burns due to arc flash events are the largest single category of electrical injuries. To address this problem, NIOSH OMSHR researchers conducted a study of such injuries from an 11-year period, with findings that included the determination of organizational and human behavior components of arc ...
