The Arc Flash Institute recommends most facilities consider a two-level PPE program as outlined in NFPA 70E Section 130.5 (G) and Table 130.5 (G). The first level is from 1.2 to 12 cal/cm2. The second level is from 12 cal/cm2 up to 40 cal/cm2 ( or greater ). In practice, 40 cal/cm2 was often the cutoff for "safe" work and the highest PPE ...
The progression of an arc flash event starts with an arc fault, which is essentially a short circuit conducted between two live parts, or by one live part and one ground, creating ionized air. The next event in this progression is referred to as the arc flash. Think of an arc flash as the extreme heat and blinding light produced by the arc fault.

What is Arc Flash? Arc flash (often called a flashover) is a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system. For example, when a wire makes contact with an earthed system.
Arc Flash Advisors can help in reviewing or developing a comprehensive electrical safety program that supports an overall site safety program. An effective program should include a certified training program, awareness of electrical hazards and self-discipline of employees. It should also identify hazard/risk evaluation procedures, electrically ...
Understanding "Arc Flash" Simply put, an arc flash is a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to ground. The results are often violent and when a human is in close proximity to the arc flash, serious injury and even death can occur.
We offer a wide variety of arc flash and electrical hazard studies, including: Arc flash analysis. Electrical power studies. Protective device environments. Motor start analysis. Short circuit analysis. Power flow studies. Our engineers are all members of IEEE, the organization setting the standards for arc flash studies.
At the top of the label is the warning label. It's a warning designed to grab your attention and make you aware of the hazards that exist. Note that it explicitly describes two hazards (arc flash and shock). This is very important as a shock hazard is statistically a greater danger than its counterpart.
Arc flash shirts come in a variety of styles and colors but ultimately need to perform one task. This task is to protect a person's torso and arms (down to the wrists) from an arc flash. Most arc rated shirts will have an arc rating around 8 cal/cm2. Here are some worth taking a look at: mwg comfort weave 9.0 cal.
The arc flash boundary is calculated to 1.2 calories/cm2 of incident energy. That's the distance where a worker without appropriate PPE would receive second-degree burns. Sometimes this boundary is the furthest one from the exposed equipment, other times the limited approach boundary is the furthest out. When the arc flash boundary is the ...
