When there is a danger of being exposed to an electric arc, personnel are advised to wear arc approved protective clothing. IEC 61482-2 is the overall standard that covers protective clothing against the thermal arc hazards of an electric arc. The IEC 61482-2 standard also covers various aspects of the garment design. This is a requirement for selling garments for arc flash protection within the EU.
Garments complying with all of these requirements outlined under IEC 61482-2 should be marked with the IEC 61482-2 symbol as well as the level of protection it meets.
