An arc flash assessment evaluates your electrical system to determine the potential for dangerous arc events – sudden releases of energy caused by electrical faults. By calculating incident energy levels and identifying hazardous areas, we help you implement the proper safety measures to reduce risk, including the determination of the necessary PPE to protect your employees from the heat, light, and blast effects of an arc fault incident.  

The Occupational Safety and Health Administration (OSHA) mandates that employers create a work environment free from recognized hazards that could lead to serious injury or death. A critical element of this requirement involves conducting an arc flash risk assessment, which helps employers identify potential arc flash dangers. Non-compliance can lead to hefty fines, liability, and preventable injuries. Arc flash analysis ensures that your electrical system is compliant with these regulations, minimizing the risk of accidents and keeping your workforce safe.

Comprehensive Electrical System Analysis – We evaluate your electrical distribution system to identify arc flash risks.

Comprehensive One-Line Diagrams – We create detailed, accurate one-line diagrams of your electrical system, giving you a clear overview of your infrastructure and helping you visualize areas of concern. One-line diagrams also serve as an excellent reference for emergency shutoff and lock-out tagout procedures!

Detailed Labeling – Clear, compliant labels are applied to assessed equipment, informing workers of potential hazards. Labels include the appropriate personal protective equipment (PPE) based on the analysis results.

High-Risk Panel Identification & Mitigation – Beyond standard assessments, we work closely with you to identify panels and equipment at the highest risk for arc flash incidents. We provide tailored recommendations to minimize risks, such as adjusting system design, upgrading equipment, or enhancing protection strategies.

Clear Communication and Review – We don’t just hand over the results – we guide you through the findings, explain the risks in practical terms, and collaborate with you to develop an actionable plan for improvement.

Many insurance companies require arc flash assessments as part of their risk management criteria. By completing this analysis, you can potentially lower your facility’s insurance premiums – with the savings often covering the cost of the assessment in a short time. Investing in arc flash analysis doesn’t just pay off in safety – it pays for itself over time. Let Curious Engineering Consulting help you enhance safety, achieve compliance, and save money.

It’s important to recognize that over time, buildings may undergo change – equipment can be added, removed, or modified. Any alterations to overcurrent protective devices, conductor lengths, or equipment locations could render previous calculations from your arc flash assessment invalid, putting you and your employees at risk of unsafe working conditions. Conducting regular reviews or audits helps identify potential gaps and ensures that your workplace remains safe and compliant. Per NFPA 70E 130.5, an arc flash risk assessment “shall be reviewed periodically, at intervals not to exceed 5 years, to account for changes in the electrical distribution system that could affect the results of the arc flash risk assessment.” When changes occur, or as the 5-year milestone approaches, Curious Engineering Consulting is ready to provide ongoing support to ensure continued compliance.
