Materials, Design & Other Characteristics :
DHK's ARC4™ ArcPlus™ pants are manufactured with a single layer of inherently flame resistant fabric. Two front, two back pockets and 7 belt loops are standard features. Buttons are sewn on using a diagonal stitch. All seams are safety stitched for strength and durability, and outer seams are triple stitched for extra strength. All components including buttons, labels, Nomex® zipper tape, Nomex® threads and Nomex® inter-liners are flame resistant.
Arc Rating : 6.9 cal/cm² ATPV
 
Color : Navy Blue & Khaki
 
Fabric : 6.8 oz/yd², Nomex® IIIA
 
Fiber Content : 98% aramid & 2% antistatic fiber
 
Sizes :Waist sizes range from 26” to 52” in increments of 2’’. For inseams and outseams see chart below.
 
Standards : Complies with NFPA 70E-2004 & ASTM F1506-02a.Tested according to ASTM F1959-04.
Use : DHK’s ARC4™ ArcPlus™ pants are designed to provide protection from arc flash heat exposures. According to NFPA 70E Hazard Risk Category (HRC) levels,this garment equals the 4 cal/cm² minimum requirement for Hazard Risk Category 1. Be aware that the arc rating (ATPV) of a fabric, as defined in ASTM F1959-04, indicates a 50% probability of a second-degree burn based on the Stoll curve. Consult Oberon’s ARC4™ clothing labels or BIRG™ (Burn Injury Reduction Guide SM ) for reduced probability of a burn injury . Always perform a hazard analysis and use higher protection than the hazard you are facing.
Cleaning Instructions & Maintenance : All garments should be free of contaminants. Flammable contaminants can reduce protection level. Garments can be machine washed with detergent and tumble-dried. Oberon’s inherently flame resistant garments will not lose the flame resistant properties of the fabrics due to laundering of the garment.
