Bombs And Explosives Flashcards
What are the three types of training?
Non criminal disposal of explosives-military souvenirs old blasting caps
Criminal investigations-use of explosions, threaten use of explosives
Post blast- investigation if a crime scene where it detonated, determine components and suspect
What is the mission of bombs and explosives?
1) render safe explosive devices
2) dispose of explosives/chemicals, fireworks, ammunition and ordnance
3) conduct investigations of post blast scene
4) provide training to community and police in recognition of explosives/chemicals/ biological hazards
What was the first explosive used with?
Black powder
What is the officer safety rules?
Primary rule: if a suspected device found, do not handle it, and secure area
Secondary rule: always assume there is more than one bombing device/threat/ until it has been found
Third rule: never pick up or dissemble a pipe bomb or any IED
What is high vs low explosives?
Low- will deflagrate- burn rather than detonate- explode. Used as propellants
High-designed to shatter, rather than push.
What are the three basic explosions?
Mechanical- over pressurization causes failure of a container
Chemical explosions- chemical reaction results in substantially instantaneous release of heat and gas
Nuclear explosions- energy released at an atomic level
What are the three primary affects when an explosive is detonated?
Blast pressure
Fragmentation
Incendiary or thermal
What are the phases of the blast pressure?
Positive - white rapidly expanding circle called the shock front. Pressure is formed once detonation
Negative phase- partial vacuum is formed by outward pushing of air away from detonation
What is the most common cause of death?
Fragmentation-causes secondary injuries
What are explosive initiators?
Time fuse
Non electric flash tubing
Blasting caps
What are the two low explosives?
Black powder
Smokeless powder
What are high explosives?
1) Binaries
2) Dynamite
3) Detonating cord
4) TNT
5) C-4
6) boosters
7) shaped charges
8) fire line
9) deta sheet
