    Abstract

    Polymer lined flexible hoses can be vulnerable in high-pressure oxygen systems. Ignition within a hose occurred after pressurization. The hose was not protected with a distance piece. However, a key factor appears to have been the presence of contaminants of hydrocarbons. The trail of contaminants leading from the ignition point and following the path of flow is shown in the analysis of this failure.
