Dangers of cryogen exposure
Webcryogen temperature Tc and heat transfer coefficient hc may not be constant during the cryogen spurt, this approach is only a first approximation, which has been shown to describe the cooling dynamics of epoxy phantoms reasonably well [19,20]. Parameters Tc and hc may vary with a number of fac-tors, including the cryogen delivery device, atomizer WebHazards of Cryogens. Cryogenic liquids (or cryogens) are liquified gases that are cooled below room temperature-most cryogenic liquids are below -150°C. When a small amount of cryogenic liquid is converted into gas, a very large volume of gas is created. Under WHMIS, cryogenic liquids are classified as compressed gases.
