Arc flash incidents are one of the most dangerous electrical hazards in the workplace. To minimize risks, the IEC 61482 standard provides international guidelines for protective clothing against arc flash. For employers, understanding this standard is critical when selecting FR and IFR garments that keep workers safe and ensure compliance.
IEC 61482 (Protective Clothing Against the Thermal Hazards of an Electric Arc) is the key international standard for arc flash protection. It evaluates garments under two main testing methods:
1. IEC 61482-1-1 (Open Arc Test)
Measures the Arc Thermal Performance Value (ATPV) or Energy Breakopen Threshold (EBT).
Expressed in cal/cm², showing how much arc energy the fabric can withstand.
2. IEC 61482-1-2 (Box Test)
Simulates an arc in a controlled environment.
Classifies garments as:
Class 1: Protects against 4 kA arc current
Class 2: Protects against 7 kA arc current
For industries such as oil & gas, utilities, power generation, and electrical maintenance, compliance with IEC 61482 is not optional—it's a necessity. Employers must:
Provide Certified Garments – Ensure workers wear FR or IFR clothing tested to IEC 61482.
Match Protection to Risk – Higher energy environments require higher arc ratings or Class 2 garments.
Ensure Comfort and Durability – Workers need lightweight, breathable protection to stay compliant throughout long shifts.
Both Flame-Resistant (FR) and Inherently Flame-Resistant (IFR) garments can meet IEC 61482 requirements:
FR Garments: Cost-effective, treated fabrics offering reliable protection when maintained properly.
IFR Garments: Made from fibers with built-in flame resistance, offering permanent protection and long-term durability.
Choosing the right type depends on budget, usage frequency, and long-term safety goals.
At DOMEX SAFETY, we manufacture IEC 61482-compliant FR and IFR garments designed for arc flash protection in demanding industries. Our collection includes:
Arc-rated coveralls, jackets, and trousers
Multi-standard garments certified to IEC 61482, NFPA 70E, ASTM F1506, and NFPA 2112
Custom solutions tailored to specific jobsite risks
For employers, IEC 61482 compliance is essential to worker safety and legal responsibility. By choosing the right FR or IFR garments, companies not only meet international safety standards but also protect their most valuable asset—their people.
