Le phénomène Arc Flash/ Arc flash phenomenon SAFETY DIVISION Effets d un arc flash sur le corps humain Effects of an arc flash on the human body Brûlures aux 2 ème et 3 ème degré 2 nd and 3 rd degree burnings 7
SAFETY DIVISION FR vs Non FR Typical non-fr workwear can ignite at 4-5cals
Evaluation des risques / Risks assesment SAFETY DIVISION Calcul du niveau de protection / Calculation of protection level Energie (CAL/cm²) = Puissance + Distance + Temps Energie (CAL/cm²) = Power + Distance + Duration Une énergie de seulement 1.2 cal/cm 2 cause une brûlure du 2 ème degré sur la peau d un individu. 1.2 cal/cm² produces a 2 nd degree burn 1 cal/cm 2 équivaut à l exposition de la flamme d un briquet sur un doigt pendant une seconde. 1 cal/cm² is equivalent to expose your finger to a lighter during 1second
SAFETY DIVISION Clothing for protection against thermal effects of arc flash hazard International IEC 61482-2 (Product standard) France / Europe / International NF EN IEC 61482-1-1 (ATPV test method) NF EN IEC 61482-1-2 (BOX test method) 10
SAFETY DIVISION Protective gloves against thermal effects of arc flash France / Europe International IEC level USA - Under consideration ASTM F2675 11
SAFETY DIVISION Face protection against thermal effects of arc flash hazard France / Europe GS-ET-29 (Recognized as the official European Standard by the European commission) International IEC level Under consideration 12
SAFETY DIVISION Face protection for UV from Arc Flash France / Europe NF EN level International IEC level NF EN 170 Under consideration UV 13
SAFETY DIVISION Face protection for physical impact from arc flash France / Europe NF EN level International IEC level NF EN 166 Under consideration physical impact 14
Conclusion SAFETY DIVISION 1. This presentation gives a practical overview of the standardization 2. A risk assesment is the first step 3. Based on EN and IEC standards the employer can protect the worker, 4. Except for gloves were the employer can use the ASTM F2675 standard 15
