What are some characteristics of high explosives?

High explosives are materials that are characterized by a very high rate of reaction, high pressure development, and the presence of a detonation wave. The guideline applies to the following explosives: blasting explosives in bulk or in packaged form, e.g.; ANFO (ammonium nitrate / fuel oil);

What are characteristics of all explosions?

What are three characteristics of all explosions? The three characteristics are a large release of energy, production of quickly expanding gas molecules, and a rapid reaction rate.

What are the 3 classification of explosives?

There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.

What are the classification of explosives?

The class of explosives includes: a) explosive chemicals; b) explosive items, except devices containing explosive chemicals in such quantity or of such a character that their inadvertent or accidental ignition or initiation does not cause any effect external to the device either by projection, fire, smoke, heat or loud …

What is the characteristic of explosion Class 8?

A sudden reaction takes place with the release of heat and light and the evolution of a large amount of gas takes place it is called an explosion.

What are explosives made of?

Chemical composition

A chemical explosive may consist of either a chemically pure compound, such as nitroglycerin, or a mixture of a fuel and an oxidizer, such as black powder or grain dust and air.

What are the functions of explosive?

Explosive – any chemical compound, mixture, or device, the primary or common purpose of which is to function by explosion, i.e., with substantially instantaneous release of gas and heat, unless such compound, mixture, or device is otherwise specifically classified by the U.S. Department of Transportation; see 49 CFR …

What is the best description of an explosive?

An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.

What is a Class 4 explosive?

Class 4 – Flammable solids; Substances liable to spontaneous combustion; Substances which, on contact with water, emit flammable gases.

What are the two types of explosives?

There are two major categories, high explosives and low explosives. High explosives are further divided into initiating, or primary, high explosives and secondary high explosives.

What are the main effects of explosions?

Explosion effects generally include those of overpressure, thermal effects, energized projectiles (fragments, debris, and missiles), ground shock, and cratering.

What is explosive strength?

What is Explosive Strength? Explosive strength is the speed at which you can use your strength! It involves heavy loading in shorter high speed movements for a few repetitions with long rest periods between. Think one rep max vertical leap, or one rep max snatch/clean and jerk. In non workout terms, think a punch.

What are Class 1 explosives examples?

341.11 Class 1 Divisions

Division 1.1 consists of explosives that have a mass explosion hazard. Examples are black powder, nitroglycerine (desensitized), dynamite, most types of torpedoes, and mercury fulminate.

What are Class 1.4 explosives?

division 1.4 consists of explosives that present a minor explosion hazard. the explosive effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected.

What is hazard classification code?

The term ‘hazard classification code’ (HCC) refers to an alpha-numeric symbol that denotes the complete HCC for a particular nature. The code consists of two or three digits indicating the hazard division followed by a letter corresponding to the compatibility group, e.g. 1.3G.

What are the two classes of high explosives What are the differences between the two classes?

Detonating explosives, such as TNT and dynamite, are characterized by extremely rapid decomposition and development of high pressure, whereas deflagrating explosives, such as black and smokeless powders, involve merely fast burning and produce relatively low pressures.

What explosive class is C4?

C4 is an RDX based plastic explosive that is mouldable by hand to form demolition charges of various shapes and weights for EOD or general demolition tasks. C4 Plastic Explosive is fully compliant with the UN Convention on the Marking of Plastic Explosives for the Purpose of Detection Regulations (MPER96 amended).

What are the 4 hazard categories?

  • Biological Hazards. …
  • Ergonomic Hazards. …
  • Chemical Hazards.

What is a 1.2 explosive?

(2) Division 1.2 consists of explosives that have a projection hazard but not a mass explosion hazard. (3) Division 1.3 consists of explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard.
