Total body disruption is the most severe and invariably fatal primary injury. [2] Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. [3] The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract.
Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion. Substances that diffuse efficiently in human tissue, e.g., hydrofluoric acid , sulfur mustard , and dimethyl sulfate , may not react immediately, but instead produce the burns and inflammation hours after the contact.
Chemical exposure to the skin is a common workplace injury and may also occur in domestic situations with chemicals such as bleach or drain-cleaners. The exposure of chemicals to the skin most often results in local irritation to the exposed area. [9] In some exposures, the chemical will be absorbed through the skin and will result in poisoning ...
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.
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 ...
The chemical reaction produces heat and pressure, and some beetles exploit the latter to push out the chemicals onto the skin; this is the case in the beetle Metrius contractus, which produces a foamy discharge when attacked. [14]
The generation of heat in large quantities accompanies most explosive chemical reactions. The exceptions are called entropic explosives and include organic peroxides such as acetone peroxide. [6] It is the rapid liberation of heat that causes the gaseous products of most explosive reactions to expand and generate high pressures. This rapid ...
Although tetryl is among the most toxic explosive compounds, it is very short-lived. This combined with the fact that the health impacts of this compound are largely unstudied, not much is known about any health problems that this compound may cause. Epidemiological data shows that tetryl has most effect on the skin, acting as a strong irritant ...
