NFPA 70E Arc Flash and Shock Hazard Boundaries. As a result of accidents in the workplace related to arc flash, the National Fire Protection Association (NFPA) has developed specific approach boundaries designed to protect employees while working on or near energized equipment.

NFPA 70E: Understanding Approach and Arc Flash Boundaries ...

Limited and Restricted Approach boundaries deal with shock and are determined by NFPA 70E Tables 130.4(C)(a) for AC systems and 130.4(C)(b) for DC systems, while Arc Flash boundaries are determined through an Arc Flash Analysis or through the use of the use of the Arc Flash PPE Categories in 130.7(C)(15)(a).

What are the shock approach and arc flash boundaries ...

Arc Flash Boundary (AFB) The AFB is a safe approach distance from energized equipment or parts. NFPA 70E establishes the default arc flash boundary at 4 feet for low voltage (< 600V) systems where the total fault exposure is less than 5000 amperes-seconds (fault current in amperes multiplied by the upstream device clearing time in seconds).

Arc Flash - CEC - Engineering Firm Serving OK & TX

Arc Flash. An arc flash is a dangerous incident that can release an enormous amount of energy in only fractions of a second due to an electrical fault within a system. The result is extremely high temperatures exceeding the temperature of the sun, an excessive pressure blast, and shrapnel being hurled at high velocity in molten and solid form.

The difference between arc flash working distance and ...

The arc flash boundary is the distance away from an arc flash where someone would be able to receive a second-degree burn. Sounds crazy but that's what it is. They used to call it the arc flash protection boundary until someone pointed out that it did not protect anyone from anything (well maybe third-degree burns).
