The Bureau of Mines has funded the development of two items of mine rescue team equipment in order to make mine rescue missions safer and more efficient. A 2-h breathing apparatus was developed with the goals of low profile, light weight, positive pressure, cooler breathing air, and low breathing resistance. These goals were achieved through the use of efficient design, proper choice of materials, dual spring-loaded breathing bags, and an internal heat exchanger. The apparatus, the LP-120, has a profile of 10 cm, weights 10 kg, and contains 240 L O2. A rescue team helmet was also developed that combines the functions of full head protection, breathing apparatus facepiece, communications, and lighting. This helmet was designed to be used with the LP-120.
