Prevention
It is important to teach children how to avoid fire and scalding. Firefighters and community leaders often lead such programs in schools and clinics.Smoke alarms installed in homes can reduce deaths resulting from fire by half. Homeowners should change batteries at least once a year and replace smoke alarms every decade. Before fire occurs, a family should practice evacuating the home, and when fire occurs the family must leave the residence immediately (within two minutes). Sources of flame, like matches, should be kept out of childrens reach. Stoves, ovens, space-heaters, and candles must not be left unattended, and flammable objects must be kept at least 30 cm away from open flames. Fire extinguishers should be stored in the kitchen, where most house fires start.To prevent children from getting burned, water temperature must not be set too high when taking baths or washing hands, nonflammable sleepwear should be worn, back burners should be used when cooking something on the stove, and hot foods, drinks, and irons should be kept away from the edge of counter and table. Oven mitts and potholders must be used in handling hot containers. Care should be taken when taking hot foods out of microwave ovens, and covers should be opened gently to reduce the risk of steam burns. Treatment
The most important first action is to stop the burning process. The source of the burn should promptly be removed (or the patient removed from the source).
In some regions, such as the western United States, wildfires are responsible for an increase in burn injuries. Wildfires can suddenly shift due to changing wind directions, making it harder for firefighters and eyewitnesses to avoid getting burned. If clothing catches fire, third-degree burn can develop in a matter of just a few seconds. Hot objects
Solid objects that are hot can also cause contact burns, especially in children, who may intentionally touch things they dont know are too hot to touch. Such burns imprinted on the skin usually form a pattern that resembles the object. Sources of burns from solid objects include ashes and coal, irons, soldering equipment, frying pans and pots, oven containers, light bulbs, and exhaust pipes. Pathophysiology
There are three (or sometimes four) degrees of burns, in ascending order of severity and depth. For more information, see Signs and symptoms. According to Jacksons thermal wound theory, there are three zones of major burn injury. Zone of coagulation is the area that sustained maximum damage from the heat source. Proteins become denaturated, and cell death is imminent due to destruction of blood vessels, resulting in ischemia to the area. Injury at this area is irreversible (coagulative necrosis & gangrene) 
Zone of stasis surrounds the coagulation area, where tissue is potentially salvageable. This is the main area of focus when treating burn injuries. Zone of hyperemia is the area surrounding the zone of stasis. Perfusion is adequate due to patent blood vessels, and erythema occurs due to increased vascular permeability.
