		Explosives are grouped into two main classes, low explosives, which burn at rates of inches per second, and high explosives which burn at hundreds of meters per second.
		Primary explosives, because of their sensitivity, may be initiated by applying shock, friction, flame, heat, or any combination of these conditions.
		Some secondary high explosives cannot be detonated simply by a primary explosive such as a blasting cap unless the detonation wave of the primary high-explosive blasting cap is amplified or boosted.

	EXPLOSIVES SAFETY (DANGEROUS GOODS CLASS 1) (Site not responding. Last check: 2007-11-05)
		An explosive is defined as ‘a material which, when suitably initiated, decomposes with the rapid formation of a large volume of gas at high temperature’.
		Explosives may be solid, liquid or gaseous, and may be single substances or mixtures of different substances.
		Explosive Safety Certificates typically report : ‘sensitiveness to direct mechanical shock’, ‘sensitiveness to friction’, temperature of ignition’, ‘inflammability’, ‘behaviour on inflammation’, ‘chemical stability’, ‘special precautions’, ‘poisonous ingredients’, ‘method of preparing and filling’, and ‘general precautions to be observed during manufacture and use’.

		Care should be taken to ensure the primary explosive is notpresent in the area of the tube to be crimped, as this crimping with thisprimary in between the tube walls could very well cause the prematuredetonation of the cap.
		Forthis primary explosive to detonate it must be loose in the detonator shell.It would be best used in caps where the base charge is pressed in first.Rifle shell improvised blasting caps would not work well with thisexplosive due to this property.
		This primary explosive should bekept dry, as it could begin to decompose in the presence of moisture.MANUFACTURE- Measure 15 grams of sodium chlorate into a large mouth pint bottle.Sodium chlorate is the oxidizer in matches.

	Explosive material - Wikipedia, the free encyclopedia
		Explosives are classified as low or high explosives according to their rates of decomposition: low explosives burn rapidly (or deflagrate), while high explosives undergo detonation.
		The term "detonation" is used to describe an explosive phenomenon whereby the decomposition is propagated by the explosive shockwave traversing the explosive material.
		Explosive force is released in a direction perpendicular to the surface of the explosive.

	Initiating element for non-primary explosive detonators - Patent 5385098
		Primary explosives cannot be transported in bulk but has to be locally produced at each detonator plant.
		For practical purposes a primary explosive can be defined as an explosive substance able to develop full detonation when stimulated with a flame or conductive heating within a volume of a few cubic millimeters of the substance, even without any confinement thereof.
		Unlike propellents, an unrestricted acceleration of reaction rates is an advantage in explosives for the present purposes and high values for the A and N constants mentioned and porosities for exposing large burning surfaces are typical adaptions in the present connection.

		Primary explosives are generally used in electric and percussion primers (blasting caps) to start a detonation.
		Secondary explosives have the highest energy outputs of any explosive and are used for blasting, demolition, or fragmentation type applications where a high energy shock wave is desirable.
		The general characteristics of secondary explosives are compared with those of primary explosives in the Explosives Data Table of Figure 2.

		An explosive is a substance that, under the influence of heat, shock, or some other agency, undergoes a chemical reaction that causes it to decompose or break up quickly with more or less violence (whew).
		Explosives fly to pieces because the materials composing them react in such a way that solids or liquids are suddenly converted into gases, which tend to expand and rapidly fill a larger volume of space.
		Primary Explosives Primary Explosives, or initiators as they are sometimes called, explode or detonate when they are heated or subjected to shock.

	Non-primary explosive detonator - Patent 4727808
		The presence of even a small charge of primary explosive makes a conventional detonator hazardous to handle because it is sensitive to mechanical deformation or impact, such as when accidentally bent or impacted at the region of the primary charge.
		The manufacture of the primary explosive, the handling of the same and the shell filling operations during manufacture of the detonator are risky operations which require extreme care and caution which in turn means costly operations and expensive plants.
		The detonation of the secondary explosive is caused by another secondary explosive that is compressed and arranged in a confined enclosure in a steel tube having specific dimensions.

		An explosive is a material, either a compound or a mixture of compounds, capable of rapid decomposition which produces heat and often gas.
		Primary explosives are commonly used as primers in ammunition.
		High explosives are generally more powerful, producing a greater shock than primary explosives; however, because they are less sensitive to heat and pressure, they usually require the explosion of a primary explosive in order to detonate.

		This explosive is not as sensitive as ot hers in this publication to primary explosive requiring 2 G. mercury fulminate or 1.25 grams of H.M.T.D. Methylamine is a basic building block of modern chemistry.
		This is a good feature as requirements for explosives made with concentrated acids take time to produce and cannot be produced as fast or c h eaply.
		The other drawback of this explosive i s the fact that it requires larger quantities of primary explosive as other base explosives.

		In OB operations, explosives or munitions are destroyed by self-sustained combustion, which is ignited by an external source, such as flame, heat, or a detonation wave.
		In an electric system, electric current heats a bridge wire, which ignites a primary explosive or pyrotechnic, which in turn ignite or detonate the material slated to be burned or detonated.

	Fuzes
		From the standpoint of the explosive train, it is convenient to divide the explosives into three classes; primary explosives, priming mixtures, and high explosives.
		High explosives have the characteristic of low sensitivity to heat or shock and function under the influence of the shock of the primary explosive or of another high explosive.
		Although the primary explosive of the fuze is the most sensitive component in the explosive train, it sensitivity varies depending on the type of fuze system.
