Liquid Helium emergency infrastructure and plan
Liquid helium is the only element and can remain a liquid at -452.5° F and is essential to cool the superconducting magnets inside NMR spectrometer instruments. NMR instruments cannot be shut down and therefore must be continually filled with liquid helium to keep the magnetic coils from overheating. Failure to keep these instruments filled with liquid helium results in overheated magnets or complete instrument destruction.
