Fire hood retains fire protective qualities after wear and washing

Fire hood retains fire protective qualities after wear and washing Royal Navy RN fire fighters have recently been provided with a new twoply hood made from 20 per cent polybenzimidizole80 per cent permanent flame retardant Rayon fibre made from regenerated cellulose. After 1520 days of use during livefire training and regular washing the new type hood appeared to be suffering from excessive wear and there was concern that the level of protection might have decreased. To examine this, 25 new and 25 used hoods worn and washed approximately 1520 times were exposed to flame, five each at 2, 4, 6, 8 and 10s using a flame manikin head to ascertain the predicted burn injuries. The new hood was shown to provide excellent protection against the most severe flame engulfment to which RN personnel might accidentally be exposed. There was no evidence that the protection afforded by the hoods was reduced by prolonged use and washing and therefore it was safe for the newtype hood to remain inservice. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Clothing Science and Technology Emerald Publishing

Abstract

Royal Navy RN fire fighters have recently been provided with a new twoply hood made from 20 per cent polybenzimidizole80 per cent permanent flame retardant Rayon fibre made from regenerated cellulose. After 1520 days of use during livefire training and regular washing the new type hood appeared to be suffering from excessive wear and there was concern that the level of protection might have decreased. To examine this, 25 new and 25 used hoods worn and washed approximately 1520 times were exposed to flame, five each at 2, 4, 6, 8 and 10s using a flame manikin head to ascertain the predicted burn injuries. The new hood was shown to provide excellent protection against the most severe flame engulfment to which RN personnel might accidentally be exposed. There was no evidence that the protection afforded by the hoods was reduced by prolonged use and washing and therefore it was safe for the newtype hood to remain inservice.
