A material for a glove for handling cryogenic liquids which will not only be effective in preventing contact with cold metal but which will also avoid the risk of holdingcryogenic liquid in contact with the skin. If liquid splashes onto bare skin the flash gas released when the liquid approaches (to it) the extremely hot surface of the skin prevents physical contact of the droplet. Consequently liquid which splashes or even flows over our hand for a brief period will not cause injury. This bare skin can be maintained by using a glove manufactured out of a hollow mono-filament fibre such as terylene of about 1mm in diameter. The fibre can be knitted into a gloveshape to form a very open but fairly thick weave. The thickness of material means that cold pipes and fittings can be handled without coming into contact with the skin with the knitted hollow mono-filament acting as an effective thermal insulator whereas any liquid sprayed onto the gloved hand will not be trapped by the "cloth" but may be shaken free.
