The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
Extensive damage can also be inflicted upon the auditory system. The tympanic membrane (also known as the eardrum) may be perforated by the intensity of the pressure waves. Furthermore, the hair cells, the sound receptors found within the cochlea, can be permanently damaged and can result in a hearing loss of a mild to profound degree. [4]
Rust scale forming and flaking off from a steel bar heated to its forging temperature of 1200°C. Rapid oxidation occurs when heated steel is exposed to air. Rust is a general name for a complex of oxides and hydroxides of iron, [4] which occur when iron or some alloys that contain iron are exposed to oxygen and moisture for a long period of ...
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
The primary concern for explosives safety with a fire involving A&E is that it may transition to a more severe reaction, causing detonations of additional or more hazardous explosives devises and placing more people or property at a greater degree of risk of damage, destruction, injury, or death.
Explosive velocities are always higher than the local speed of sound in the material. If the explosive is confined before detonation, such as in an artillery shell, the force produced is focused on a much smaller area, and the pressure is significantly intensified. This results in an explosive velocity that is higher than if the explosive had ...
The amount of damage depends on the victim’s health, age, the location of the bite, the quantity of venom, and how quickly they receive medical attention. Deaths from these bites are rare but ...
Under the UN Dangerous Goods classification, explosive hazard Divisions are awarded using the UN Manual of Criteria and Tests, by following the process flow chart '10.3 Procedure for assignment to a division of the class of explosives' and conducting the appropriate tests either UN series 5, series 6, or series 7 tests.
