Scalding is a form of thermal burn resulting from heated fluids such as boiling water or steam. Most scalds are considered first- or second-degree burns, but third-degree burns can result, especially with prolonged contact. The term is from the Latin word calidus, meaning hot. [1]
A thermal burn is a type of burn resulting from making contact with heated objects, such as boiling water, steam, hot cooking oil, fire, and hot objects. Scalds are the most common type of thermal burn suffered by children, but for adults thermal burns are most commonly caused by fire. [ 2 ]
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ionizing radiation (such as sunburn, caused by ultraviolet radiation). [5] [9] Most burns are due to heat from hot liquids (called scalding), solids, or fire. [10] Burns occur mainly in the home or the workplace.
The Lund and Browder chart is a tool useful in the management of burns for estimating the total body surface area affected. It was created by Dr. Charles Lund, Senior Surgeon at Boston City Hospital, and Dr. Newton Browder, based on their experiences in treating over 300 burn victims injured at the Cocoanut Grove fire in Boston in 1942.
The critical heat flux is an important point on the boiling curve and it may be desirable to operate a boiling process near this point. However, one could become cautious of dissipating heat in excess of this amount. Zuber, [6] through a hydrodynamic stability analysis of the problem has developed an expression to approximate this point.
Various methods of treatment are used, depending greatly on the length of exposure and other factors. There are documented cases using both conservative and invasive treatments, including skin grafting and/or the application of nonadhesive dressing alongside topical corticosteroids to reduce inflammation. However, the use of steroids may ...
Boilover onset mechanism. The extreme violence of boilovers is due to the expansion of water from liquid to steam, which is by a factor of 1500 or more. [3] In practical storage scenarios, the presence of water under the burning fluid is sometimes due to spurious accumulation during plant operation (e.g., rainwater entering a seam in the tank roof, off-specification products from the source ...
Preventing razor burn: The best way to prevent razor burn is to make sure you’re using shaving cream made with emollients and a sharp, clean razor. An emollient-rich shaving cream protects and ...
