Cryogenic liquids present significant hazards because of their intense cold and substantial gas production when warmed. The extreme cold can not only cause tissue damage to personnel, but also bring about changes in the properties of metals and other materials. Asphyxiation and over-pressure hazards are created by the potential for production of large quantities of gas.

These problems require that careful attention be given to the storage, transfer, and use of cryogenic liquids in order to assure the safety of personnel working with them.

DOE, Office of ScienceOne of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE’s Office of Science by Brookhaven Science Associates, a limited-liability company founded by Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
