Arc Flash Coordination Study

Analysis

As part of our comprehensive Arc Flash hazard analysis, we will ensure total compliance with all the latest NFPA 70E and OSHA requirements. We offer a complete turn-key solution for your Arc Flash project.

  • Our team will travel to your facility, open your equipment, and gather all required data without interruption to your facility's normal daily operations.  
  • We enter this data into our power analysis software and perform a number of analyses including short circuit, arc flash, and device rating evaluation.
  • We will generate a single line diagram of your facility's power system.
  • We generate and install Arc Flash warning labels on all required equipment.
  • We will offer recommendations to reduce many of your facility’s higher ratings, to improve coordination, and to reduce other issues uncovered during the project.
  • Finally, we provide complete reporting and documentation that can be presented as proof of your facility’s compliance with the latest Arc Flash requirements.
  • We also offer complimentary support for 12 months for minor revisions.
  • Additionally, we offer   NFPA 70E Arc Flash Safety Training.


An Arc Flash is a rapid release of energy during an arcing fault between two electrical conductors. The fault is typically initiated by a dead short between the conductors, the cause of which generally burns away during the initial flash. The arcing fault is then sustained by the establishment of a highly conductive plasma, limited only by the impedance of the arc. This fiery explosion devastates everything in its path, violently discharging deadly shrapnel and molten metal. The core of an Arc Flash can reach temperatures as high as 35,000°F. 


What are the Dangers?

Injuries from an Arc Flash are among the leading causes of workplace fatalities. Thousands of workers are treated in specialized burn trauma centers each year as a result of Arc Flash injuries. Burns are not the only danger. The pressure wave from an Arc Flash can knock workers off ladders or platforms and even throw them across the room against walls or other hazardous equipment. The sound blast from an Arc Flash can cause eardrums to rupture resulting in temporary or permanent hearing loss. Even the bright flash from the event can cause temporary or permanent blindness. A high level arc flash blast will most likely result in significant equipment damage and potentially personal injury or death.


Is an Arc Flash Hazard Analysis required?

Per OSHA Part 1910.132(d)(1), an employer is required to assess their workplace to determine if hazards are present, or are likely to be present, which necessitates the use of personal protective equipment (PPE). If so, the employer must select, and have each employee use, proper PPE to protect each affected employee from the hazards. OSHA also requires the employer to provide written certification of this hazard assessment, identifying the workplace evaluated, the person certifying the evaluation, and the date. 

Additionally, NFPA 70E-2012-130.5(C) states electrical equipment that is likely to require examination, adjustment, servicing, or maintenance while energized shall be field marked with a label containing the following: 1.) the incident energy, 2.) the system voltage, and 3.) the Arc Flash boundary. The Arc Flash boundary is defined in NFPA 70E-2012-130.5(A) as the distance at which the incident energy equals 1.2 cal/cm2. Therefore, this distance must be calculated for each piece of equipment. 

What better way to ensure compliance with these and other requirements than to perform a comprehensive Arc Flash Hazard Analysis. Furthermore, should you choose not to do anything, OSHA can and has cited companies for a “willful act of negligence” not to comply with these requirements.
