CITP Test 5; The Last One! ACTUAL
QUESTIONS AND CORRECT ANSWERS
What are the effects of an explosion? - CORRECT ANSWERS Thermal
Effect
Blast Pressure Effect
Fragmentation Effect
T/F: Thermal effecs are generally the most damaging of the three primary
effects? - CORRECT ANSWERS False; Fragmentation is usually the
most damaging.
What is important to know about thermal effect high explosives? - CORRECT
ANSWERS They produce higher temperature thermal effects but for a
shorter duration.
What is important to know about thermal effect low explosives? - CORRECT
ANSWERS They produce lower temperature thermal effects but for a
longer duration.
What is the blast pressure effect? - CORRECT ANSWERS When very
hot gases are formed in approximately 1/10,000 of a second expand out from
the point of detonation at supersonic velocities, up to 20,000 mph.
What are the two distinct phases of the blast pressure effect? - CORRECT
ANSWERS The Positive Phase and Negative Phase.
T/F: The negative phase is typically three times longer than the positive phase
but less intense. - CORRECT ANSWERS True.
, The four types of injuries sustained during a blast are: - CORRECT ANSWERS
Primary Blast Injury: Direct effects of blast upon the body
Secondary Blast Injury: Propelled fragmentation
Tertiary Blast Injury: Casualty's body is propelled against a stationary object
Qauternary Blast Injury: Being crushed or burns.
___________ blast injury is the most common cause of death in explosions. -
CORRECT ANSWERS Secondary Blast Injury (Fragmentation)
IED's may have precut/preformed objects (ie ball bearings, hexagonal nuts,
nails, etc) placed within or along the device to serve what purpose? -
CORRECT ANSWERS To form fragmentation when the IED detonates.
What is primary fragmentation? - CORRECT ANSWERS Fragments
produced by the IED or explosive container.
What is secondary fragmentation? - CORRECT ANSWERS Object
propelled from around the detonation point, and fractured pieces of the intended
target that become lethal missiles.
IED's generally consist of what four components? - CORRECT ANSWERS
Power source
Initiator
Explosive
Switch
(PIES)
