Question 1
Which of the following statements regarding blasting agents is FALSE?
Answer
Plastic explosives are generally excluded from Type D listings.
Dynamite and blasting gelatin are examples of Type A agents.
Type B agents cannot contain nitroglycerin.
Type E agents incude substances consisting of water as an essential ingredient.
Question 2
Neoprene, which is present in roofing tiles and flexible hose, is made from a polymerizing reaction of what known human carcinogen?
Answer
1,3 butadiene
TCCD
Tetrafluoroethylene
Chloroprene
Question 3
The shock waves produced during the detonation of a chemical explosive are linked with its potential shattering power called the __________.
Answer
explosophore
blasting agent profile
brisance
explosive train
Question 4
What separates a combustion reaction from a detonation?
Answer
Only one happens at 1200 degrees Fahrenheit.
The Law of Sixes (.six seconds to six minutes reaction time) explains the separation.
Combustion involves an inorganic component only.
Detonation does not require the interplay of atmospheric oxygen or other oxidizers.
Question 5
Nitric acid is used to produce all of the following commercially available explosives EXCEPT:
Answer
Tetryl
Nitroglycerin
ead Azide
TNT
Question 6
Even though polyurethane fires can be effectively extinguished with water, what other important fact must be taken into account when dealing with this material?
Answer

Fires involving these products retain considerable heat; therefore, it is essential to check for total fire extinguishment.
Breakdown products from these fires are potential human carcinogens.
All water used to extinguish these fires must be diked or retained for treatment as a hazardous waste.
Dioctyl phthalate, an extremely toxic byproduct, is produced.
Question 7
Which of the following is an intermediate product in the production of methyl methacrylate?
Answer
Vinyl acetate
Acrylonitrile
Acetone cyanohydrin
Isocyanate
Question 8
Why do foam rubber products catch fire easily within a hot clothes-dryer or under a heating blanket while their cousins, vehicular rubber tires, do not?
Answer
The heat of combustion is so high with foam rubber products that they catches fire easily.
The increased surface area of the reactants (blowing and trapping inert gases in foam) causes the foam rubber to have an increased reaction rate.
The statement that foam rubber products burn more quickly than vehicular rubber tires is false; both products burn at the same rate and initial ignition temperature.
The greater weight of vehicular rubber tires means it burns more slowly.
Question 9
In 1995, an explosive mixture of what two products destroyed the Murrah Federal Building in Oklahoma City, OK?
Answer
Ammonium nitrate and fuel oil
Dynamite (straight) and ammonium nitrate
Amatol and fuel oil
Tetryl and amatol
Question 10
What is the term or phrase that refers to the events beginning with the initiation of the primer and ending with the detonation of the bursting charge?
Answer
Brisance
Explosive train
Explosophore
Deflagrating event
