Information That Should Be On an Arc Flash Study Report
Know what an arc flash study report should include (methodology, equipment ratings, worst-case incident energy, and labels) before you hire a consultant.

To ensure the electrical safety of their workplaces, companies will invest in arc flash analyses, and each one ends in an arc flash study report. An arc-flash risk assessment and incident energy analysis evaluate the electrical system to quantify the thermal hazard: the incident energy in cal/cm² at a stated working distance, the arc-flash boundary at which incident energy falls to 1.2 cal/cm², and the arc-rated PPE and work practices required under NFPA 70E®. Calculations follow IEEE Std 1584-2018, which addresses incident energy and boundary distance only; neither IEEE Std 1584 nor NFPA 70E provides a method for calculating arc-blast pressure or projectile hazard, so a study should not be described as determining a facility’s risk of an arc blast. Without receiving an arc flash analysis, businesses become much more susceptible to seeing employee injuries, infrastructure issues, and reputation damages.

If your business is about to invest in its first arc flash analysis, you may wonder what to expect. Once arc flash consultants evaluate your electrical system, they’ll provide you with an arc flash study report. Dreiym Engineering uncovers what to expect during an arc flash analysis, along with the information that should be on an arc flash study report.
Different Aspects of an Arc Flash Analysis
Arc flash consultants will perform a thorough assessment of your company’s electrical system. To ensure they can provide all the information that should be on an arc flash study report, they’ll carry out the following actions around your corporation’s site:
- Assemble existing layouts of electrical systems on the site.
- Verify your company’s layout documents with the help of arc flash analysis software.
- Gather all your equipment piece’s specifications, such as size, model, type, manufacturer, etc.
- Create arc flash labels to prompt safe electrical equipment operations.
Information Included in an Arc Flash Study Report
As you may infer, each step to create an arc flash study results in valuable information for arc flash consulting teams. Once arc flash consultants complete their study, they’ll make a comprehensive report to return to their client. This report will include the following information:
- A complete description of the study’s results as well as the methodology they used, such as the IEEE 1584 calculation method and NFPA 70E requirements
- A breakdown of short-circuit equipment that your company utilizes beyond its ratings and alternatives for the equipment or operations
- A list of any equipment that has considerable arc flash hazards
- Details on a worst-case-scenario energy blast per a hazardous electrical system’s modes of power
- The calculated incident energy at the working distance and the arc flash boundary for each bus or piece of equipment
- The minimum arc-rated PPE required for work on each piece of labeled equipment
- Information regarding the software used to perform the arc flash study
