Q.E 18

• Implosion – is similar phenomenon except that the energy released is initially directed inward.
• Mechanical Explosion – it is a sudden breaking apart, shattering or bursting into pieces by internal pressure as that of

  gas or steam boiler; also known as pressure explosion.
• Chemical Explosion – a source of explosion wherein the source of this energy comes from an explosive such as

  gunpowder.
• Nuclear explosion – an explosion due to nuclear fusion and fission of particles.
• Act #2255 (11 Feb 1913) – act prohibiting the manufacture, possession and sale of dynamite and other explosives or

  components without a special permit, from Chief, PC or Senior Inspector in the province
• Executive order #9 (01 Feb 1954) – control and supervise licensing sales, possession, use, storage and manufacture of

  explosives.
• Executive order #60 (09 Feb 1967) – promulgating rules and regulations on the control and supervision of the

  importation, sale and possession of chemicals used in manufacture of explosives
• Gunshot residue –is defined as the traces of materials that remain after the use of a firearm using gunpowder

  ammunition.
• Primer or Lead Residue – are devices used to initiate the propellant in ammunition
• Propellants Components – contain up to 23 organic compounds (FBI study).
• Black powder propellants –the trick to making as suitable ballistic propellant was in the correct ratio of the three (3)

  chemicals.
• Smokeless propellants – since the discovery of nitrocellulose in 1845, by treating cellulose
• Flake – common form of propellant
• Cylindrical – are mistakenly called extruded. This is technically incorrect because nearly all propellants are extruded at

  some point in their manufacturer
• Cut sheet – common and European propellant. Cylindrical powders are mistakenly called extruded
• Stabilizer and Plasticizer – stabilizers are organic material that are added to propellants and explosives to retard their decomposition during storag
• Burning rate – is the rate at which energy released during burning.
• Slow-burning powders –release their energy (in the form of pressure) more slowly than fast-burning powders.
• Fast-burning powders –are commonly used for light loads with light bullets.
• PARRAFIN WAX – A white, translucent, odorless solids consisting of a mixture of solids hydrocarbons of high molecular weight.
