Arc flash is a significant electrical hazard resulting from electrical arcs, which has caused severe burns, injuries, fatalities among electrical workers worldwide, as well as considerable damage to property and equipment. For global organizations, electrical safety should not just be a concern, but a responsibility.
UK law mandates that employers must protect workers from electrical hazards. The Electricity at Work Regulations 1989 and the Management of Health and Safety at Work Regulations 1999 require a “suitable and sufficient” risk assessment for electrical systems. Failure to comply can result in HSE enforcement notices, fines, and even prosecution. Conducting an arc flash study demonstrates due diligence and legal compliance.
Multinational companies often adopt uniform safety practices across all sites to maintain consistency and reduce liability. In the UK, performing arc flash studies ensures alignment with NFPA 70E, IEEE 1584, and IEC standards, creating a globally integrated safety program.
Arc Flash Hazard Analysis is a critical component of electrical safety management. It determines the incident energy levels that could be released during an arc flash event and identifies potential hazards within an electrical network. This analysis provides actionable recommendations to mitigate risks and protect operational personnel.
One of the primary outcomes of the study is the specification of appropriate Personal Protective Equipment (PPE) as the last line of defence against arc flash incidents. In addition, the analysis recommends risk reduction strategies, such as adjusting protection settings or updating switching procedures to isolate areas with high incident energy levels, thereby minimizing the likelihood and severity of arc flash events.
A well-executed Arc Flash Hazard Analysis not only ensures compliance and safety but also contributes to a culture of proactive risk management. By identifying hazards, determining exposure levels, and implementing effective controls, employers can significantly reduce the likelihood and impact of arc-flash incidents.
PSC has extensive experience in Arc Flash Hazard Analysis and supports our clients from the outset with data collection of electrical networks to the final issue of the report and Arc Flash label installation. Our team has a deep understanding of the relevant standards, such as the IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations, NFPA 70E Standard for Electrical Safety in the Workplace and the Electricity at Work Regulations 1989, supporting the safety of operational personnel.
