An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.
Hydrogen safety. The Hindenburg disaster is an example of a large hydrogen explosion. Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704 's highest rating of four on the flammability scale because it is flammable when mixed even in small ...
Quantity-Distance (QD) is the foundation of DOD explosives safety standards. It defines levels of protection from blast based on relationships between the quantity of explosive material (NEW) and distance. The relationships are based on levels of risk considered acceptable for specific exposures but they do not provide absolute safety or ...
Gurney equations. The Gurney equations are a set of mathematical formulas used in explosives engineering to relate how fast an explosive will accelerate an adjacent layer of metal or other material when the explosive detonates. This determines how fast fragments are released by military explosives, how quickly shaped charge explosives ...
Explosive velocity, also known as detonation velocity or velocity of detonation (VoD), is the velocity at which the shock wave front travels through a detonated explosive. Explosive velocities are always faster than the local speed of sound in the material. If the explosive is confined before detonation, such as in an artillery shell, the force ...
Class 1: Explosives. Division 1.1: Explosive that has a mass explosion hazard. A mass explosion is a detonation of almost entire load instantaneously. Division 1.2: Goods and Substances without a mass explosion hazard, but with a projection (shrapnel/fragmentation). Division 1.3: Goods and substances with a mass fire hazard, and a minor, blast ...
ATEX Directive 2014/34/EU was published on 29 March 2014, by the European Parliament. It refers to the harmonization of the laws of the Member States relating to equipment and protective systems intended for use in potentially explosive atmospheres. Regarding ATEX 99/92/EC Directive, the requirement is that Employers must classify areas where ...
A U.S. Army Special Forces paratrooper conducts a high-altitude low-opening military freefall jump with an MK–54 SADM. The Special Atomic Demolition Munition (SADM), also known as the XM129 and XM159 Atomic Demolition Charges, [1] and the B54 bomb [2] was a nuclear man-portable atomic demolition munition (ADM) system fielded by the US ...
