Protective clothing for the arc flash market has continued to evolve in recent years, bringing with it new technological processes and fibres which now enable garment layering to provide optimal protection against arc flash. The principle of layering gives the benefit of creating air gaps between the layers, dissipating the energy in the event of an arc flash. It is also an easy way of achieving a higher level of protection without becoming too heavy, for example layering thin layers such as a jacket or coverall over a base layer. However, it is critical that each layer has been tested and qualified as an arc flash protection PPE. Additionally, the economic crisis has put an emphasis on cost savings on all levels, including protective workwear, and has led safety engineers to look for multi-hazard, one fits all needs garments with maximum wearer comfort.
