Tinker Air Force Base, OK, in conjunction with the Environmental Security Technology Certification Program (ESTCP) and the Joint Group on Pollution Prevention (JG-PP) coordinated efforts with Versar Inc., in regard to pollution prevention issues identified during a defense system's acquisition process. The primary objectives of this task were to reduce or eliminate the use of CFC-113, a Hazardous Material (HazMat), and to avoid duplication of efforts in action required to reduce or eliminate HazMats through joint service cooperation and technology sharing. The Scope of work was to design, develop and construct a prototype oxygen line cleaning system (POLCS), and cleaning process, to precision-clean the critical life support oxygen distribution system for the Air Force B-1B weapon system (and other aerospace vehicles) while all equipment and tubing remains installed onboard the aircraft. The POLCS design will provide the Air Force with a suitable and applicable fluid system that will meet or exceed special operation and cleanliness requirements in accordance with Government and non-Government documents for maintaining on-board aerospace vehicle oxygen tubing. This effort also included testing, troubleshooting and the validation of a selected solvent solution on various aerospace vehicles using the POLCS. Laboratory testing began in October 1999; field-testing was conducted during fall 2001.
