A hydrofluoric acid burn is a chemical burn from hydrofluoric acid. [ 1] Where it contacts the skin it results in significant pain, swelling, redness, and skin breakdown. [ 1][ 2] If the fumes are breathed in swelling of the upper airway and bleeding may occur. [ 2] Complications can include electrolyte, heart, lung, kidney, and neurological ...
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ultraviolet radiation (such as sunburn ). [ 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. In the home, risks are associated with domestic ...
Acute radiation syndrome. Radiation causes cellular degradation by autophagy. Acute radiation syndrome ( ARS ), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [ 1] Symptoms can start within an hour of ...
The main causes of death and disablement in this state are thermal burns and the failure of structures resulting from the blast effect. Injury from the pressure wave is minimal in contrast because the human body can survive up to 2 bar (30 psi) while most buildings can withstand only a 0.8 bar (12 psi) blast.
Heartburn, also known as pyrosis, cardialgia or acid indigestion, [ 2] is a burning sensation in the central chest or upper central abdomen. [ 3][ 4][ 5] Heartburn is usually due to regurgitation of gastric acid (gastric reflux) into the esophagus. It is the major symptom of gastroesophageal reflux disease (GERD). [ 6]
Lightning injuries are injuries caused by a lightning strike. [4] Initial symptoms may include heart asystole and respiratory arrest. [1] While the asystole may spontaneously resolve fairly rapidly, the respiratory arrest is typically more prolonged. [1] Other symptoms may include burns and blunt injuries. [1]
Microwave burns are burn injuries caused by thermal effects of microwave radiation absorbed in a living organism.. In comparison with radiation burns caused by ionizing radiation, where the dominant mechanism of tissue damage is internal cell damage caused by free radicals, the type of burn caused by microwave radiation is by heat—health effects colloquially associated with the term ...
A chemical burn occurs when living tissue is exposed to a corrosive substance (such as a strong acid, base or oxidizer) or a cytotoxic agent (such as mustard gas, lewisite or arsine ). Chemical burns follow standard burn classification and may cause extensive tissue damage. The main types of irritant and/or corrosive products are: acids, bases ...
