What is an arc flash and why is it dangerous?

​

An arc flash is a sudden, explosive release of energy caused by an electrical fault. It produces intense heat, blinding light, pressure waves, and molten metal debris — all within milliseconds. Arc flash incidents are among the most severe hazards in electrical work environments and can cause serious burns, injuries, and fatalities. Identifying and mitigating arc flash risk is a critical component of electrical safety compliance.

​

What is an arc flash study and what does it involve?

​

An arc flash study is a comprehensive engineering analysis of your electrical system that calculates the incident energy levels at each piece of equipment. The study identifies hazard boundaries, required personal protective equipment (PPE) levels, and equipment labeling requirements. BCES Global's arc flash studies are conducted in accordance with CSA Z462 and NFPA 70E standards and cover your full power distribution system from the utility service entrance through to end-use equipment

​

Is an arc flash study a legal requirement?

​

Yes. Canadian and U.S. electrical safety regulations require employers to assess arc flash hazards in the workplace. CSA Z462 in Canada and NFPA 70E in the United States both mandate arc flash risk assessments and appropriate hazard labeling on electrical equipment. Failure to comply can result in regulatory penalties and significant liability in the event of an incident.

​

Does BCES Global handle both the analysis and the remediation?

​

Yes. BCES Global provides end-to-end arc flash services — from the initial engineering study and hazard analysis through to implementing the recommended corrective actions. This includes equipment upgrades, system modifications, protective device coordination, and labeling. Having a single provider handle both phases ensures that remediation work is directly aligned with the findings of the study.

​

How often should an arc flash study be updated?

​

Industry standards recommend reviewing your arc flash study whenever significant changes are made to your electrical system, and at a minimum every five years. Changes that trigger a reassessment include new equipment installations, utility service changes, load growth, and modifications to protective devices. BCES Global can help you determine whether your existing study is current or requires updating.
