Materials not normally considered to be combustible may be so in an oxygen-enriched atmosphere. In an oxygen-enriched atmosphere, materials that are combustible and flammable in air ignite more easily, burn more vigorously and produce a higher temperature when burning. This venting may create an oxygen-enriched atmosphere if the container is stored in a confined space. If the container is tipped over or placed on its side, a larger amount of oxygen will be vented. When a liquid oxygen container is not used for a period of time, there is a small amount of oxygen vented into the vicinity of the container. The transfer of liquid oxygen from one container to another can create an oxygen-enriched atmosphere within the vicinity of the containers.Here are some important elements to remember relating to the storage and use of liquid oxygen: Pressure producing potential of the vaporization and/or liquid expansion processes.Very cold temperature of the liquid and vapor (it's classified as a cryogenic fluid), and.Transferring (also referred to as transfilling) of liquid oxygen from one container to another presents several potential hazards, which include the: The 1999 edition of NFPA 99 is adopted by reference in the 2000 edition of NFPA Standard 101 ( Life Safety Code). This Information Bulletin outlines the basic requirements of National Fire Protection Association Standard 99 (NFPA 99) for the safe storage, transfer and use of liquid oxygen in a health care facility. The use of liquid oxygen in health care facilities has increased dramatically in the past few years. Attachment 1: Locations Used For Transfilling of Liquid Oxygen Purpose
