ASTM Committee G-04 published several guides and a manual that outline a process for identifying and analyzing fire hazards in oxygen systems. Many companies and government agencies have accepted this process and require hazards analyses to be performed on oxygen systems. When an oxygen hazards analysis is performed, the results are usually documented to identify the hazards associated with the system and its components.
The information needed to perform an oxygen hazards analysis include details on system components, configuration, and operating conditions. Material flammability, ignitability, and potential damage data are also used when analyzing oxygen hazards. In the past, word processing and spreadsheet tools have been used to document results. However, the wide variety of numerical data, explanatory text, and pictures or graphics makes it difficult to retrievably catalog hazards data using word processing and spreadsheet tools.
Recently, the NASA White Sands Test Facility (WSTF) was requested to do an increased number of oxygen hazards analyses. In doing so, it became apparent that many oxygen systems use the same components with slight variations. However, with the existing tools, all data had to be re-entered for each analysis. To increase efficiency and precision of analysis, an electronic database for performing oxygen hazards analyses was developed.
The database provides a repository of all information used in hazards analyses, including drawings, materials data, and environmental information that can be used for future analyses. Furthermore, the analyses of both systems and components remain available for future reference, allowing users to quickly access all data and past analyses as a reference for performing current analyses and answering questions that arise during the process. This paper presents the design, layout, advantages, and potential uses of this database.
