What can cause a a thermal burn?

Answer 1

Heat from radiation or conduction (contact).

The "burn" from very cold substances is not actually a burn, but has some of the same characteristics. Freezing temperatures (such as dry ice) will rupture cells in the same way that burns do, but by forming ice crystals instead of steam. Tissue damage and necrosis can progress in a similar manner from both injuries. One major difference is that there is no heat oxidation (charring) in ice burns.

Answer 2

A thermal burn occurs when skin or other body tissues come into contact with extreme heat or cold. The most common cause of thermal burns is exposure to high temperatures. Here are some factors and sources that can cause thermal burns:

Hot liquids: Scalds from hot liquids such as boiling water, hot oil, or steam can cause thermal burns.

Flames: Direct contact with flames or hot objects can result in burns. This can happen in situations like fires or explosions.

Hot surfaces: Touching hot surfaces, like stovetops, heated metal, or hot appliances, can cause thermal burns.

Electricity: Electrical currents can generate heat and cause burns if there is contact with live wires or electrical equipment.

Radiation: Exposure to intense sources of radiation, such as the sun, tanning beds, or industrial equipment, can lead to thermal burns.

Chemical exposure: Some chemicals can cause thermal burns upon contact with the skin, either due to their heat-producing properties or their corrosive nature.

Friction: Friction between the skin and a rapidly moving object or surface can generate heat and result in thermal burns.

Cold exposure: While not traditionally considered thermal burns, exposure to extremely cold temperatures or objects can cause frostbite, which is a form of cold thermal injury.

The severity of a thermal burn depends on factors such as the temperature of the heat source, the duration of exposure, and the sensitivity of the affected area. It's important to treat thermal burns promptly to minimize damage and prevent complications. Immediate first aid typically involves cooling the affected area with cool (not cold) water and seeking medical attention if the burn is severe.
