What is the first step that must be done before anyone enters the explosion site?
What is the first step that must be done before anyone enters the explosion site? The entire bomb site must be systematically searched with great care given to recovering any trace of a detonating mechanism.
What is the blast effect?
4.1 BLAST EFFECTS As the reaction progresses, the solid or liquid explosive material is converted to very hot, dense, high-pressure gas. The explosion products initially expand at very high velocities in an attempt to reach equilibrium with the surrounding air, causing a shock wave.
Who investigates explosions?
The FBI
The FBI investigates the malicious damaging or destruction, by means of an explosive, of property used in interstate or foreign commerce. These matters include the bombing or attempted bombing of college or university facilities and incidents that appear to have been perpetrated by terrorist or revolutionary groups.
What is the importance of explosives analysis?
Analysis of explosives in storage is important for assessing the purity of their components, the uniformity of composition, and the various decomposition products.
What are the common methods of analyzing explosives and explosive contents please provide details?
Several methods have been used to detect and measure RDX in explosive materials and debris from explosions. The most common separation procedure is HPLC, but HRGC has also been used. These methods have been paired with several types of detectors, including TEA, MS, electrochemical detection, and UV.
What are the different types of explosives and their characteristics?
explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. 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 is UXO army?
Unexploded Ordnance (UXO) It includes sea mines or shells used by the Navy, mortar bombs, mines, artillery shells or hand grenades used by the Army; bombs, rockets or missiles used by the Air Force; and many other types of ammunition and explosives including training munitions.
Why does Kayce open his mouth?
Keeping ones mouth open is said to equalize pressure, therefore reducing internal damage.
What kind of result should we expect from explosive analysis?
What kind of results should I expect from explosives evidence analysis? During the analysis, scientists will confirm the type of explosion that occurred, and identify the type of explosive material and any explosive precursors such as diesel fuel or ammonium nitrate used in fertilizer, that may have been used.
