First-Aid Procedures for Cryogenic-Induced Injuries

WebThe difference between a refrigeration and a cryogenic system lies in the achievable temperatures, with the dividing line being set at −100°F or −74°C. The methods used and the physical principles applied to achieve low temperatures are shown in Table 1. Method Physical principle Cyclic processes WebThese substances undergo no chemical reactions under any known circumstances. They are nonflammable, noncombustible and nontoxic. They can asphyxiate. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved.
