This is a hazard warning label for Liquid Oxygen (Refrigerated Liquid Oxygen, UN1073) manufactured by Matheson Tri-Gas. The label identifies the product as an extremely cold, oxidizing liquid and gas under pressure that vigorously accelerates combustion and can cause frostbite.

The label provides critical safety warnings and handling instructions. It prohibits smoking and open flames in areas where the product is stored or used. Key restrictions include keeping oil, grease, and combustibles away from the product, using only equipment cleaned for oxygen service, storing and using the product with adequate ventilation, and maintaining container temperatures below 52°C (125°F). Personnel must wear face shields and gloves when handling, avoid spills, and refrain from walking or rolling equipment over spilled liquid oxygen. The label explicitly warns that combustibles in contact with liquid oxygen may explode upon ignition or impact, and that contact with the liquid can cause frostbite. First aid instructions direct users to obtain immediate medical treatment for frostbite cases and reference the Matheson Tri-Gas Material Safety Data Sheet (MSDS) for additional information. The label instructs users not to remove the product label.
