X00-X09: Exposure to smoke, fire and flames

X03: Exposure to controlled fire, not in building or structure

Exposure to controlled fire, not in a building or structure, involves situations where a person is present around a fire that is managed and monitored, but not within any built environment. The condition is caused by close contact with open flame, hot gases, or heated surfaces, typically involving outdoor activities like camping, bonfire events or in controlled burn situations. Symptoms of this exposure may include burns on the skin or injuries to the respiratory tract due to inhalation of hot gases. The severity of symptoms can range from mild, superficial skin burns to severe, life-threatening injuries, depending on the intensity and duration of exposure to the fire. This condition directly affects the integumentary system (skin, hair, nails) and in some cases, the respiratory system as well, depending on the mechanism and extent of exposure.
