What should be the arc thermal performance value of clothing selected for a specific application?

The arc thermal performance value (ATPV) of clothing selected for a specific application should indeed be higher than the potential hazard. The ATPV is a measure of how much arc energy a fabric can withstand before it fails and no longer provides protection.

In environments where electrical hazards are present, the higher the ATPV, the better the clothing will be at preventing skin burns in the event of an arc flash. If the ATPV is lower than the potential hazard, it means that the clothing may fail to provide adequate protection, leaving the wearer vulnerable to serious injuries. Thus, ensuring that the clothing has an ATPV that exceeds the potential hazard is crucial for the safety of individuals working in high-risk electrical environments. This selection helps to mitigate the risks associated with arc flash incidents, contributing to safer work conditions.
