Step 2. Assess the risks. Step 3. Control the risks. Step 4. Review control measures. Consultative committee for work-related fatalities and serious incidents. The committee was established to ensure there is an ongoing consultative forum for injured workers and families affected by a workplace death, illness or serious incident.
Arc Flash Analysis An arc flash occurs when an electrical path is broken in some way and the electricity jumps or “arcs” to a nearby grounded object. It is basically the same as lightning but can often be much more powerful and dangerous. It is usually caused by exposed wire where the rubber insulation has broken down…

· An arc flash study (also known as an arc flash analysis) is an electrical engineering analysis of a facility’s electrical distribution system that determines how hot an electric arc explosion can get (what’s known as the incident energy) at any point that a worker might interact with that system. The arc flash study produces all the ...
· Electrical systems are designed for electrical current to flow through conductors. However, when this current travels through air, an arc is formed. This event is called arc flash and poses significant risk toward the safety of personnel, property, and productivity. At 480V (the voltage that powers the majority of equipment in most facilities ...
The equations and methods in IEEE 1584 should be used for arc-flash analysis whenever possible, but the Hazard/Risk categories in NFPA 70E and the theoretical model for calculation of arc-flash levels (also included in IEEE 1584) may be useful in some situations. ...
