Exam 17: Forensic Aspects of Fire and Explosion Investigation

Dynamite has largely replaced ammonium-nitrate-based explosives for industrial uses.

A search of the fire scene must focus on finding the fire's point of origin.

________ is an explosive consisting of ammonium nitrate soaked in fuel oil.

Which is often used as the explosive core in a detonating cord?

Factors that can contribute to abnormal observations at a fire scene include:

Following microscopic examination,the recovered debris is thoroughly rinsed with ________.

Which is a natural heat-producing process that may give rise to a fire?

Water does not interfere with laboratory methods used to detect and characterize flammable liquid residues.

Warm air expands,which causes it to become ________ dense.

The minimum temperature at which a fuel will spontaneously ignite is called:

Which is an initiating explosive often used in detonators?

Which is an explosive readily detonated by heat or shock?

The ingredients in black powder are potassium nitrate,carbon,and ________.

Which is a device used to screen objects for the presence of explosive residues?

Heat energy can ignite distant objects through the transmission of:

What is the main advantage of analyzing accelerant residues from a fire using the vapor concentration technique over the headspace technique?

Combustion is accompanied by the production of noticeable heat and light.

Which type(s)of screening and confirmation tests are used for analyzing evidence of explosives?
