This is a warning label for a container of Refrigerated Liquid USP Oxygen, regulated under UN 1073. The label cautions users to keep the container upright, not to change or force-fit connections, and to avoid smoking as oxygen vigorously accelerates combustion. It warns that combustibles in contact with the liquid oxygen may explode on ignition or impact and also cautions that liquid oxygen may cause severe frostbite. The label instructs users to keep oil, grease, and combustibles away, use only equipment cleaned for oxygen service, and avoid spills. It includes instructions for liquid withdrawal and emphasizes the importance of wearing gloves and a face shield. The label also provides first aid instructions and warns that uninterrupted use of high concentrations of oxygen over a long duration, without monitoring its effect on oxygen content of arterial blood, may be harmful. Finally, the label includes information on the company producing the product and warns not to remove the label.*
