OXYGEN, REFRIGERATED LIQUID is a dangerous substance used for emergency medical applications. It should be handled with extreme caution, as it is an oxidizing liquid gas under pressure that vigorously accelerates combustion. The substance is extremely cold and can cause severe frostbite. The warning label on the container warns against changing or forcing connections and strictly forbids smoking in its presence. As combustibles in contact with liquid oxygen may explode on ignition or impact, the container should be kept upright, and only suitable oxygen service equipment should be used with it. Persons who come into contact with the substance should use a face shield and gloves when dealing with it, and should avoid getting it in their eyes, on their skin, or on their clothing. In the presence of oxygen, oil, grease, and combustibles are also hazards. The substance should be stored and used under adequate ventilation to reduce the risk of respiratory problems. If someone gets frostbite, they should seek medical attention immediately. This liquid should only be used by properly trained personnel for oxygen deficiency and resuscitation emergencies. Continuous use of this substance without monitoring its effect on the oxygen content in arterial blood is harmful.*
