Arc Flash

Engineering Power Solutions specialises in arc flash safety for offshore oil & gas platforms, wind turbines, industrial plants around the globe. From support in the early planning stages to training of your personnel, a full range of services is available to help you increase work safety and save time.

The package is based on a hierarchy of risk control measures based on the following principles:

  • Predict – Calculate the arc flash incident energy severity
  • Prevent – Eliminate or remove the hazard at source
  • Protect – Provide protection to personnel in the form of PPE
  • Publish – Signage and training

The four principles are based on the DuPont ™ Arc-Guide which uses IEEE 1584 Guide for Performing Arc Flash Hazard Calculations 2015.

These four methods ensure compliance with the European Council Directive 89/391/EEC EU Health and Safety Directive. This approach complies with both U.S. and European legislation.

We’ll support you and add value as follows:

  1. Identify the arc flash hazard potential (calculate the arc flash energy)
  2. Provide solutions to remove the hazard by design or procedures (Arc flash detection, protection adjustments, changes to operational procedures)
  3. Undertake a risk assessment for each switchboard / MCC based on HSE Guidelines (Task based)
  4. Guidance and support on which PPE manufacturer to choose and PPE selection
  5. Arc flash awareness and training for technicians


What is arc flash?

Arc flash is what happens when a short-circuit is made in an electrical power distribution system and electrical current makes a jump through the air. This arcing is similar to lightning and poses a hazard to electrical workers that is often not considered. For more detailed information see the ‘What is arc flash (Click here)’ page.

Why should I worry about it? Isn’t this a concern for the United States only?
Arc flash risk exists anywhere people are working near energized equipment, and sometimes it is simply unavoidable to be working near a live conductor. In Europe there’s currently no legal obligation to consider it, but current standards are perfectly suited to include arc flash hazard in a work safety program.

Is there anything I can do about it?
Yes! The hazard can be calculated, reduced and mitigated. Once calculated there are plenty of measures that can be taken to either reduce or entirely remove the hazard. The remaining hazard can be mitigated through PPE.
