Other information:
Dry ice is the solid form of carbon dioxide (CO2) with a temperature at -109.3°F (-78.5°C) or below. Dry ice is especially useful for freezing and keeping things frozen because of its very cold temperature. At normal atmospheric pressure, dry ice sublimates directly into carbon dioxide gas without going through a liquid stage
Applications:
In-transit refrigeration of foods, ice cream, pharmaceuticals and other temperature-sensitive materials (like vaccines)
Process cooling during chopping/blending/mixing/mincing/grinding operations of meat
Dry ice blasting cleaning system for moulds, machinery, buildings etc.etc
Shrink fitting metal components for an interference fit e.g. axles into gear wheels
Production of fog effects for theatres, discos etc
Quick and convenient source of inert gas for purging fuel tanks etc
Freeze-branding livestock
Safety:
Intensely very cold and hence contact with bare skin should be avoided
Carbon dioxide gas is heavier than air and is an asphyxiate - care should be taken to avoid accumulation at low levels or in confined spaces
Dry Ice must not be placed in tightly sealed containers. Sufficient care (ie) vents must be provided to allow the gas evolved to escape
