- This series of three articles provides a broad overview of today’s state of the art for protecting electrical workers against electric arc thermal hazard.
- Part 1 addresses key factors for further electric arc PPE advancement.
- It also discusses the different types of electric arc and why this knowledge is important for safety professionals who perform arc risk assessments.
The entire industry of PPE against the thermal hazard of an electric arc has existed for 20 years. However, gaps still exist in electric arc knowledge and standardization. This three-article series provides a broad overview of today’s state of the art for electrical workers’ protection against electric arc thermal hazard.
Part 1 of the series identifies key factors for future progress, and discusses electric arc classification, properties, behavior and methods of thermal energy dissipation.
Statistical trends in general electric and electric-arc- related fatalities and trauma are essential for future improvements. However, information on electric arc incidents is hard to find in government statistical reviews. Part 2 of the series is dedicated to reviewing statistical data and identifying gaps in reporting electric-arc-related incidents and corresponding skin burn trauma. The authors also review previously published electric arc incidents.
Part 3 of the series discusses multiple elements for reliable protection against electric arc. These include arc hazard assessment, standardization for PPE test method requirements, results of the latest research, challenges and suggestions.
Factors for PPE Progress
Fire Retardant Materials
During the past 15 years, revolutionary changes occurred in the availability of different fabrics and materials for PPE used by electrical workers to protect against the thermal effect of an electric arc during live electrical work. Removing flammable and melting materials and fabrics from the face, body and hands was a major factor in reducing burn incidents.
