One Arrow 2Coming close to a high-amp source with a conductive
object can cause the electricity to flash over

One Arrow 2Dropping a tool or otherwise creating a spark can ignite
an arc flash

One Arrow 2Equipment failure due to use of substandard parts,
improper installation, or even normal wear and tear

One Arrow 2Breaks or gaps in insulation

One Arrow 2Dust, corrosion or other impurities on the surface of
the conductor

Current Arc Flash Boundaries

Down arrow

The arc flash boundaries are designed to keep employees safe while they are working near energized equipment.


Exposed Conductor, or Circuit
RESTRICTED Approach Boundary
(distance at which there is increased danger of shock)
LIMITED Approach Boundary
(distance at which employees could be exposed to a shock hazard)
ARC FLASH Boundary
(furthest established boundary from the energy source where heat generated could result in burns)

 




Complying with 2015 Arc Flash Requirements (NFPA 70E Standard)

Down arrow
The NFPA 70E 2012 edition instructs employers to conduct an arc flash hazard analysis (now “Arc Flash Risk Assessment”) to determine the amount of thermal energy that could be generated in an arc flash incident. The information is then used to define a flash protection boundary around the potential source, and to determine the level of arc-rated apparel and other personal protection equipment required when employees cross the boundary while they work on or near exposed live parts.

How to Label According to Arc Flash Requirements

Down arrow
To increase safety and ensure compliance throughout the workplace, it is essential to identify arc flash hazards in your facilities. Arc flash labeling is an important responsibility that should be addresses by the employer and includes the labeling of electrical equipment, such as switchboards, panel boards, industrial control boards, meter socket enclosures and meter control centers.

These labels should have relevant information to keep employees safe, including nominal system voltage, arc flash boundary and personal protective equipment information. Read more...
