ARC FLASH LAYERED PROTECTION

LAYERING ARC FLASH GARMENTS RESULTS IN HIGHER ATPV PROTECTION. THE POWER OF LAYERING When two or more electric arc flash protective garments are worn in combination, a higher level of arc flash protection is achieved. When wearing layers, a layer of air with a naturally low electrical conductivity is trapped between each garment, this helps to increase the overall insulation and protection. The total Arc Thermal Protective Value (ATPV) of layered arc flash garments cannot be worked out by adding the ATPV of each garment, because of the additional layer of air, it may be higher than the sum of the ATPV of each garment. The following page details different combinations of our garments that we have tested to demonstrate their total ATPV protection when worn together. ADDITIONAL BENEFITS OF LAYERING Layering provides increased comfort and it also allows for the wearer to adjust their level of protection based on the task.
