The term cryogenic is usually used to refer to something that produces or is related to very low temperatures. As such, the term cryogenics refer to gases that have been subjected to very low temperatures to form liquids or solids. The boiling point of these gasses is usually below -150 degrees centigrade. Nitrous oxide and carbon dioxide usually have higher boiling points but are also classified under cryogenic substances. Here are facts regarding Cryogenic gases.
Cryogenic substances occur as gases at room temperature and pressure. The process of liquefying them involves cooling them below room temperature and then subjecting them to high pressure. There are different circumstances under which cryogens become liquids. Nevertheless, there are two characteristics that cut across all cryogens. To begin with, they are extremely cold. Secondly, minute amounts of the liquid evaporate to form huge amounts of gas.
A cryogenic liquid releases very cold vapor or gas. Moisture in the air condenses around it because of the low temperature. Highly visible fog is formed as a result of the vapor produced. If the tanks used to store cryogens are poorly insulated, the air around it condenses to form liquid air mixture.
Working with cryogens can be a very risky job. As such, all people who work with these substances are required to have a good understanding of the risks that are associated with it. They are also required to employ appropriate safety measures to avoid accidents and injuries. There are several safety measures that have been invented for use by workers. It is important for workers to learn about them.
The three major categories of cryogens in existence are oxygen, inert gasses, and flammable gasses. They are all categorized under the three groups named above but each cryogen possesses its own unique qualities. Inert gasses are characterized by inability to undergo any kind of chemical reaction. They are incapable of supporting combustion and do not burn. Neon, krypton, argon, nitrogen, and helium are some of the gasses that fall under this group.
Just as indicated by the name, flammable gasses are normally highly combustible and may ignite in air. Among gasses in this category are methane, hydrogen, and liquefied natural gas. Normally, oxygen is categorized in its own group because it has a high capacity of supporting combustion. Many incombustible materials burn when there is oxygen. That is why oxygen is discussed separately in a discussion about cryogens.
Very importantly, cryogens should be stored carefully given the dangers associated with them. Thermally insulated containers are usually used for storage. Usually, these containers are designed to be able to withstand huge temperature differences. They can also tolerate temperature changes that occur rapidly.
There are several medical effects that cryogens can cause to the body. For instance, very cold gasses can cause burns on the skin which are similar to burns caused by heat. Exposure to extremely cold materials usually causes frostbites that cause the skin to appear waxy yellow in color. When tissues in the area of contact start to thaw, one experiences intense pain.
