Document Summary
Burns can be divided into five categories: flame, contact, radiant heat, scalding, chemical, microwave. Flame burns: actual contact of the body and flame with scorching of the skin progressing to charring. Flash burns: variant of a flame burn. Caused by initial ignition ( flash ) from a flash fire that results from sudden ignition of gases, petrochemicals, or fine particulate material. Typically a short duration, a few seconds at most. Contact burns: involves physical contact between the body and a hot object (surface temperatures of 70 degrees c and higher, trans-epidermal necrosis in less than 2 second). Radiant heat burns: caused by heat waves (no contact between body and flame or contact with hot surface. Skin appears erythematous (redness due to capillary dilation) and blistered with areas of skin slippage. Prolonged exposure to low heat, the skin will become brown and leathery.
