What is IEC 61482-2 Ed. 2:2018?

IEC 61482-2 Ed. 2:2018 is an internationally recognized technical standard developed by the International Electrotechnical Commission (IEC). This standard provides guidance on how to protect workers against the thermal hazards of electric arc flash events in electrical equipment. It specifies the requirements for protective clothing and personal protective equipment (PPE) to be used by personnel working in areas where there is a risk of exposure to arc flash.

The Importance of IEC 61482-2 Ed. 2:2018

Arc flash incidents can result in serious injuries or even fatalities. These incidents occur when an electric arc forms due to a fault (such as a short circuit) in electrical equipment. The energy released during an arc flash can cause extreme temperatures, intense light, and pressure waves, which can cause burns, blast injuries, and damage to hearing and eyesight. IEC 61482-2 Ed. 2:2018 plays a crucial role in minimizing the risks associated with arc flash events and ensuring the safety of workers.

Requirements of IEC 61482-2 Ed. 2:2018

IEC 61482-2 Ed. 2:2018 outlines specific requirements for protective clothing and PPE to protect workers against arc flash hazards. It defines two different classes of garments based on their performance in withstanding the thermal effects of an arc flash:

Class 1: Garments tested to withstand an arc rating of at least 4 kilojoules per square meter (kJ/m²).

Class 2: Garments tested to withstand an arc rating of at least 7 kJ/m².

In addition to these requirements, the standard also covers testing methods and procedures for evaluating the performance of protective clothing and PPE. It ensures that the garments provide adequate protection against electric arc flash incidents and meet the necessary safety standards.

Compliance with IEC 61482-2 Ed. 2:2018

Compliance with IEC 61482-2 Ed. 2:2018 is essential for organizations and individuals involved in electrical work. By following the guidelines and using compliant protective clothing and PPE, employers can minimize the risk of arc flash incidents and protect the well-being of their workers. It is important to regularly assess and maintain the effectiveness of the protective equipment to ensure ongoing compliance with the standard and the utmost safety.
