Cryogenic Fluids

#SNSInstitutions #SNSDesignThinkers #DesignThinking

Cryogenic fluids, also known as cryogens, are?liquids that have boiling points below -130° Fahrenheit (-90° Celsius).?At normal temperatures and pressures, they are gases, but become liquids at low temperatures.?

Some common cryogenic fluids include:

Argon, Carbon dioxide, Helium, Hydrogen, Methane, Nitrogen, Nitrous oxide, and Oxygen.?

Cryogenic fluids are used in research for experimentation and frozen storage.?They have several properties that make them hazardous and require special handling:?

·??????? Extremely cold

The liquids and their vapors are very cold and can cause severe burns if they come into contact with the skin.?

·??????? Expand rapidly

Small amounts of liquid can expand into very large volumes of gas.?

·??????? Visible fog

The vapors and gases from cryogenic fluids condense moisture in the air, creating a highly visible fog.?

·??????? Flammable

Some cryogenic fluids, like hydrogen, methane, and liquefied natural gas, can burn or explode.?
