Field testing of the Advanced Worker Protection System
Field testing of the Advanced Worker Protection System AWPS is a life support system that allows a suited worker in operate in a chemically hazardous or radiologically hot environment for up to 2 hours with minimal heat stress and minimal encumbrance from his life support equipment. It consists of 3 parts: a backpack using liquid air to supply breathing gas and cooling power; a liquid cooling garment (LCG) that circulates water chilled from vaporizing and warming the cryogen; and a Level B protective garment which accommodates the low profile of the backpack, permits greater mobility and doesn`t require tape closure. The AWPS backpack and LCG are compatible with commercially available Level A protective garments. A one-hour demonstration of a AWPS prototype was done.
