Mining Contract: Cryogenic Life Support Technology Development Project

Contract DetailValue
Contract #12FED1213259
Start Date7/1/2012
Research Concept

This Annex shall be for the purpose of developing cryogenic supply systems for Refuge Alternatives. Specific objectives are to conduct a feasibility study for cryogenic air and oxygen application, fabricate, test and document operational prototype supply systems, and adapt and evaluate systems for retrofitting into, or in conjunction with, existing refuge chambers. Final demonstration of the system may occur in an operating underground coal mine or NIOSH’s Safety Research Coal Mine.

Program Areas

Contract Status & Impact

This interagency agreement with NASA Kennedy Space Center involves four Annexes, as follows.

CRYOGEN AIR BREATHING APPARATUS (CRYOBA)

This Annex shall be for the purpose of developing a two hour, low-profile, liquid air SCBA prototype with an attitude independent pick up termed Cryogenic Air Breathing Apparatus (CryoBA) for use in escaping from an underground mine. Two packs will be built with the intent of meeting the provisional certification criteria under 42CFR84 and 42CFR84 Sub-part O (where applicable). This 15 month project will be funded by NIOSH-OMSHR, designed and built at NASA-KSC, machine tested at the National Personal Protective Technology Laboratory (NPPTL), and human-tested at KSC. NIOSH-OMSHR will provide funding for labor, parts, travel, and consumables. NASA KSC will provide the use of the Biomedical Engineering Lab (NASA-BRL) and other facilities as required on a non-interference basis. The KSC Biomedical Engineering Lab will partner with other NASA KSC groups, existing contractors, and outside companies as required to support this project.

LOX RETROFIT KITS FOR EXISTING CLOSED-CIRCUIT BREATHING APPARATUS (LOXK)

This Annex shall be for the purpose of developing liquid oxygen supply systems for existing entry/ rescue closed circuit breathing apparatus (CCBA) i.e. Draeger BG4 & Biomarine BioPak240R. These systems would replace the existing compressed oxygen supply cylinder. These will be developed as ‘kits’ to modify these units and termed LOX Retrofit Kits (LOXK). One each of the Draeger and Biomarine CCBA will be thus modified with these kits and tested to verify performance. This 13 month project will be funded by NIOSH-OMSHR, designed and built at NASA-KSC, machine tested at the National Personal Protective Technology Laboratory (NPPTL), and human-tested at KSC. NIOSH-OMSHR will provide the two CCBAs, funding for labor, parts, travel, and consumables. NASA-KSC will provide the use of the Biomedical Engineering Lab (NASA-BRL) and other facilities as required on a non-interference basis. The KSC Biomedical Engineering Lab will partner with other NASA KSC groups, existing contractors, and outside companies as required to support this project.

CRYO AIR STORAGE AND FILL STATION (CRYOASFS)

This Annex shall be for the purpose of developing Cryogenic Air Storage and Filling Systems for the Cryogenic Air Breathing Apparatus. Specific objectives are to conduct a concept study, fabricate, test and document operational cryogenic air supply systems, and adapt, evaluate in conjunction with cryogenic air breathing apparatus. Final demonstration of the system may occur in an operating underground coal mine or NIOSH’s Safety Research Coal Mine. NASA KSC will provide the use of the Biomedical Engineering Lab (NASA-BRL) and other facilities as required on a non-interference basis. The KSC Biomedical Engineering Lab will partner with other NASA KSC groups, existing contractors, and outside companies as required to support this project.

CRYOGENIC REFUGE ALTERNATIVE SUPPLY SYSTEM (CRYORASS)

This Annex shall be for the purpose of developing cryogenic supply systems for Refuge Alternatives. Specific objectives are to conduct a feasibility study for cryogenic air and oxygen application, fabricate, test and document operational prototype supply systems, and adapt and evaluate systems for retrofitting into, or in conjunction with, existing refuge chambers. Final demonstration of the system may occur in an operating underground coal mine or NIOSH’s Safety Research Coal Mine. BCS Life Support, LLC, working as a contractor to NASA, developed the concept of using a liquid air based breathing and cooling system for use in mine refuge alternatives. To demonstrate the feasibility of this concept, a prototype system was constructed that utilizes stored liquid air as the sole oxygen supply to replace high pressure oxygen cylinder systems. This system not only provides breathable air but a measure of cooling as well. The scope of this project will address both breathing grade liquid air and liquid oxygen supply systems for refuge alternatives. NASA KSC will provide the use of the Biomedical Engineering Lab (NASA-BRL) and other facilities as required on a non-interference basis. The KSC Biomedical Engineering Lab will partner with other NASA KSC groups, existing contractors, and outside companies as required to support this project.
