"The problem was the current procedure for mitigating small spills of liquid oxygen (LOX) inside a hospital building had not been tested to determine the procedure's effectiveness. The hypothesis being, if LOX on asphalt has been shown to be impact sensitive, then LOX on a floor tile surface will contact the tile's underlying petroleum-based adhesive through the seams or cracks of adjoining floor tiles, creating an impact-sensitive condition until mitigated. The absence in literature of a mitigation procedure for small LOX spills that could occur with portable LOX respiratory therapy equipment prompted the Kent County Memorial Hospital to develop a spill procedure. The purpose of the research was to develop and conduct a controlled LOX spill test experiment to determine the procedure's effectiveness."
