Dangers are related to cryogen exposure
Web16.10 Cryogenic Material Safety. Print Chapter. According to the Compressed Gas Association, a cryogenic fluid is a material that has a boiling point of less than -130°F (-90°C). Examples of cryogenic materials include the liquids nitrogen, argon, and helium, and solid carbon dioxide (dry ice). Hazards associated with cryogenic fluids include: WebAlthough not a cryogen, solid carbon dioxide or dry ice which converts directly to carbon dioxide gas at -78°C (-109°F) is also often used in laboratories. Cryogens, as well as dry ice, can be hazardous to workers if not handled properly. General PrecautionsWhenWorking with Dry Ice or LN 2

WebAbstract. When a cryogen spurt is applied to the skin surface for tens of milliseconds, cooling remains localized in the epidermis, leaving the temperature of deeper hemangioma vessels unchanged. The objective of this study was to compare the efficacy and safety of noncooled laser treatment (NC-LT) vs. cryogen spray cooling plus laser treatment ... WebBackground and objective: To analyze the effects of laser pulse duration and cryogen spray cooling (CSC) on epidermal damage and depth of collagen coagulation in skin resurfacing with repetitive Er:YAG laser irradiation.
