Arc Flash Services

El-Ark can provide a complete arc-flash hazard study designed to assist our customers address the NFPA’s 70E , Standard for Electrical Safety in the Workplace. This study helps to ensure employee safety against dangers associated with the release of energy caused by an electrical arc. We recommend that a short circuit analysis and a protective device coordination study be conducted concurrently with the arc flash study. (see Engineering Services)


The key elements of an arc-flash safety program are:

  • Calculation of incident energy exposure and arc-flash boundary
  • Communication of the incident energy exposure and arc flash boundaries of a possible arc source via warning label system.
  • Provide Employees with the necessary information to determine proper PPE for the task at hand.


Our Arc Flash services are based on the following industry standard practices:

  • Electric Arc Hazard Exposure (OSHA 29 CFR 1910.269)
  • Flash and Shock Hazard Analysis (NFPA 70E-2015, 130.4 and 130.5)
  • Personal Protective Clothing and Equipment for Arc Flash Hazards (NFPA 70E-2015, Table 130.7(C)(16))
  • Prescribed Equations for Incident Energy and Arc Flash Boundary Calculations (IEE Std. 1594)


Benefits of our Arc Flash Study include:

  • Improved employee safety
  • Calculated available incident energy and arc flash boundaries
  • Addressed NFPA 70E Standards
  • Provide the required detail field labeling for each system location
  • Provide up-to-date one-line drawings

Failure to address the NFPA 70E Standard can lead to very significant financial loss due to employee injuries, litigation, higher insurance premiums and regulatory fines.

OSHA 1910 regulations clearly state that a STUDY SHALL BE PERFORMED by a licensed professional.  Our Professional Engineer (P.E.) is currently licensed in AR, LA, MS and TX.  Registration in other states can be acquired as needed.


NFPA 70E 2015 Training:

Electrical dangers such as shock, electrocution, electrical explosion, and arc blast will always be present on the job, but a proper electrical training program and strategies can minimize the likelihood of injuries and fatalities. Our NFPA 70E Training focuses on the 2015 NFPA 70E arc flash electrical safety standard that addresses arc flash electrical safety requirements for employee workplaces that are necessary for the practical safeguarding of employees.  We offer various classes for "qualified employees", "unqualified employees" and management.  We can hold these classes at your facility for conveince or we offer them locally on a demand basis.

NFPA 70E for "Qualified Employees":
NFPA 70E defines a "qualified" person is "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."  We usually will train Electricians, E&I Techs, Shift Support Maintenance Staff and Electrical Engineers in this class but that is up to your facility to determine.  This class is a four (4) hour class and is conducted by one of our Engineers.  This class is required by NFPA 70E for all "qualified persons" and is recommended to be repeated every two years in order to keep personnel abreast of changes to NFPA 70E or other regulations or laws.

NFPA 70E for Operators:
Per NFPA 70E, a "Unqualified" Person is "a person who is not a qualified person."  This class usually consists of operators and non-electrical maintenance personnel.  This class takes about an hour to complete and gives the attendees a brief review of the hazards associated with electrical equipment and things that they are not authorized to do to electrical equipment.

NFPA 70E for Management:
This is a course we designed specifically for Supervisors, Planners, Safety Personnel and Managers to inform them of the electrical hazards that exist and why it is so important to follow NFPA 70E standards.  This class is a four hour class and will also be conducted by one of our Engineers.  This is a great course for facilities that doesn't have a resident arc flash expert or to take to gain a better understanding of the regulations that must be followed by every facility in the United States.
