Bomb Identification & Detection

  1. 1. LISTEN CAREFULLY! COZ ILISTEN CAREFULLY! COZ I WILL BLOW YOU UP!!!!WILL BLOW YOU UP!!!!
  2. 2. BOMB IDENTIFICATION ANDBOMB IDENTIFICATION AND DETECTIONDETECTION DefinitionDefinition :: Explosive – is any substance that whenExplosive – is any substance that when subjected to heat, shock or friction willsubjected to heat, shock or friction will undergo a very rapid decomposition thatundergo a very rapid decomposition that transform into a more stable material,transform into a more stable material, characterized by the liberation of tremendouscharacterized by the liberation of tremendous amount of heat and almost always w/ theamount of heat and almost always w/ the formation of gases, and a sudden release offormation of gases, and a sudden release of pressure that resulted to violent explosion.pressure that resulted to violent explosion.

  5. 5. DEFLAGRATIONDEFLAGRATION It is the reaction of a chemical compoundIt is the reaction of a chemical compound or the transformation from solid gasesor the transformation from solid gases whereby the speed is relatively slow overwhereby the speed is relatively slow over a sustained period. It is the very rapida sustained period. It is the very rapid burning that never reaches detonation.burning that never reaches detonation.

  7. 7. THREE BASIC TYPES OFTHREE BASIC TYPES OF EXPLOSIONEXPLOSION 1.1. MECHANICAL EXPLOSION:MECHANICAL EXPLOSION: It can be illustrated by the gradual build-up ofIt can be illustrated by the gradual build-up of pressure in a steam boiler or pressure cooker.pressure in a steam boiler or pressure cooker. 2.2. CHEMICAL EXPLOSION:CHEMICAL EXPLOSION: It is caused by the extremely rapid conversion of aIt is caused by the extremely rapid conversion of a solid or liquid explosive compound into a gaseous formsolid or liquid explosive compound into a gaseous form having a much greater volume than the substanceshaving a much greater volume than the substances from which they are generated.from which they are generated. 3.3. NUCLEAR EXPLOSION:NUCLEAR EXPLOSION: It maybe induced either by fission or fusion.It maybe induced either by fission or fusion.
