Abstract:
The United States Army Aeromedical Research Laboratory USAARL porcine cutaneous bioassay technique was used to to determine what mitigating effect four thermally protective flight suit fabrics would have on fire-induced skin damage. The fabrics were 4.8 oz. twill weave Nomex aramide, 4.5 oz. stabilized twill weave polybenzimidazole, a 4.8 oz. plain weave experimental high temperature polymer, and 4.8 oz. plain weave Nomex aramide. Each fabric sample was assayed 20 times in each of four configurations as a single layer in contact with the skin as a single layer with a 6.35 mm one-fourth inch air gap between fabric and skin in conjunction with a cotton T-shirt with no air gaps and, finally, in conjunction with a T-shirt with 6.35 mm air gap between T-shirt and fabric. Bare skin was used as a control. A JP-4 fueled furnace was used as a thermal source and was adjusted to deliver a mean heat flux of 3.07 sq cm sec. The duration of exposure was five seconds. Four hundred burn sites were graded using clinical observation and microscopic technique.
