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.
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 ...
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.
These waves mostly damage junctions between tissues of different densities (bone and muscle) or the interface between tissue and air. Lungs and the abdominal cavity, which contain air, are particularly injured. The damage causes severe hemorrhaging or air embolisms, either of which can be rapidly fatal. The overpressure estimated to damage ...
Chemical: Bombs in this class include noxious chemical materials that may cause a patho-physiological response in individuals exposed to the blast area during and post-explosion. Biological: Much like the chemical-type, with the exception that biological bombs use vector-borne pathogens or other biohazardous materials to initiate a patho ...
The cause was found by a Health and Safety Executive report to be the ignition of gas from a ruptured pipe. Nine people were killed and 37 were injured, 15 seriously. On July 30, 2004, the a natural gas pipeline exploded in Ghislenghien, Belgium. The leak was a result of the damage from a previous construction work.
Online videos of the disaster's initial moments show sparks and lights inside the smoke rising from the blaze, just prior to the massive blast
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.
