When it comes to electric arc flash protection, “layering” can be a cost-effective, practical way to clothe workers as they move between tasks with different hazard ratings. The right combination of garments increases protection against heightened risks, and can be a more effective and comfortable way to attain the different protection levels needed throughout the day.
In a perfect world, workers would wear maximum-protection arc-rated clothing throughout their shifts, and comfort and cost would not be an issue. In the real world, however, protection must be balanced with worker comfort and cost in mind. Layering becomes one possible solution for increasing arc flash protection.
