DriFire outerwear to meet new standards
18/03/2009
He explains that, because of new regulations, non-arc-rated protective undergarments no longer count. Garments now need to fulfil a new set of requirements before they can be considered arc flash clothing compliant.
According to Mr Cone, a cotton t-shirt under an arc-rated outer layer will no longer qualify as an HRC 2 garment system. In order to be considered compliant, the FR outer layer must rate at least 8 cal/cm². If not, the additional FR undergarments layers must be added to bring the system up to the full 8 cal/cm² of protection required for HRC 2.
He adds that patented layering system offered by DriFire is unique. The Total System Arc Ratings allow consumers to combine protective garments with existing coveralls or wicking shirts, allowing clients to update current clothing systems easily in order to meet the new standards.
The HRC Level 1 includes: silk-weight clothing, 5.5oz (ATPV 4.4 cal/cm²); mid-weight clothing, 6.5oz (5.2 cal/cm²); women's undergarments, 7oz (4.4 cal/cm²); and woven chambray utility shirts, 5.5oz (6.3 cal/cm²). HRC Level 2 includes: heavy-weight clothing, 5.5oz (8.7 cal/cm²); woven industrial shirts, 7oz (12.1 cal/cm²); coveralls, 7oz (12.1 cal/cm²).
The company incorporates moisture wicking with its 70E-compliant quick drying performance apparel to ensure wearers stay cool, focused and safe. Arc protection ratings for the garment system solutions include: 5.5oz DriFire chambray shirts (6.3 cal/cm²); 7oz industrial shirts (12.1 cal/cm²); 5.5oz chambray over 5.5oz t-shirt (15.1 cal/cm²) and 7oz industrial shirt over 5.5oz t-shirt (20 cal/cm²).
