38
Q

39
Q

Define explosive

A

Title 18 U. S. C. Chapter 40 Defines explosive as any chemical compound, mixture, or device, the primary or common purpose of which is to function by explosion.

40
Q

Define explosion

A

The sudden and violent escape of gases from a central point accompanied by high temperature, violent shock and loud noise

41
Q

Three types of explosions

A

Mechanical explosion

Nuclear explosion

Chemical explosion.

42
Q

Mechanical explosion

A

Purely physical and not chemical

Involves the conversion of a substance such as water into gas in the form of steam. Example would be a water heater that overheats without a pressure release valve. The result would be an explosion from the build up of steam.

43
Q

Nuclear explosion

A

Involves

Fission - the splitting of the nucleus of Atoms

Fusion- The joining of the nuclei of items under great force.

44
Q

Chemical explosion

A

Instant conversion of a solid or liquid compound into gases having a much greater volume than the original compound. Consist of an exothermic [heat] reaction that is set off and propagated by a shockwave, loud noise is often a byproduct.

Chemical explosives or unstable substances or mixtures of substances capable of undergoing sudden and violent decomposition or break up. Such as TNT and nitroglycerin or composite explosives like ANFO And flash powder.

45
Q

Low explosives

A

Characterized by deflagration (Rapid burning) And produce gasses slowly and in large amounts.

Typically move at sub sonic speed below 3300 f/s

LE typically need some type of container to explode

46
Q

High explosives

A

Decompose from an unstable solid or liquid compound or mixture to a more stable gas instantaneously. This is called detonation.

Heat in large quantities of gases travel outward at supersonic speeds over 3300 F/S and with enough force to shatter materials in close proximity. This is referred to as brisance Or the ability of an explosive to rip, tear, or break materials in close proximity.

47
Q

Explosive train

A

And ordered combination of explosives necessary to achieve an explosion; initiation is the first step in the explosive train.

48
Q

Initiation

A

Is the first step in an explosive train

The imposition of heat or shock insufficient amounts that starts [or initiates] The deflagration or detonation reaction

49
Q

Low order detonation

A

the incomplete consumption of the explosive or complete consumption, but at lower than optimum velocity, usually because of deteriorated explosives or human error [poor priming techniques].

50
Q

High order detonation

A

The complete consumption of the explosive at its optimum [highest] velocity.

51
Q

Sympathetic detonation

A

High order destinations can result in the initiation of one explosive from the shockwave of another detonation In close proximity.

52
Q

Velocity of detonation [VOD]

A

Explosive work or explosive power is directly related to the functioning velocity of an explosive.

VOD is the speed at which the shock wave passes through a column of explosives.

Detonation velocities range from 3300 to 30,000 ft./s [1100 to 9000 m/s].

53
Q

Exothermic or thermal effect

A

High explosives [detonations] produce extreme but brief heat. Resultant fires are rare

Low explosives [Deflagrations] Produce lower temperatures but for longer periods. Resultant fires are more common.

54
Q

Identify the effects of an explosion

A

Exothermic or thermal effect

Positive blast pressure [expressed in pounds per square inch or psi]

Negative blast pressure

Blast physics [Blast mitigation]

Over pressure effects on the human body

Fragmentation/shrapnel

55
Q

Low explosives

A

Consists of propellant such as black or smokeless powder and pyrotechnics such as black powder

Sensitive to heat, shock, friction and static. They are flame sensitive and deflagrate upon initiation.

Grain size FFg, FFFg. More f’s smaller the grain size.

56
Q

Safety or time fuse

A

Is a low explosive

Has a black powder core

57
Q

Pyrotechnic fuse and quick match

A

Is a low explosive

Used to initiate pyrotechnics.

Composed of black powder and surrounded by yarn and varnish [pyrotechnic fuse] or paper [quick match]

58
Q

Smokeless powder

A

Is a low explosive

Typically use as a propellant powder for modern small arms ammunition and military projectiles but also [like black powder] a filler for pipe bombs.

Sensitive to flame, heat, and static.

59
Q

Flash powder

A

Considered a low explosive but classified under that CFR as a high explosives for storage purposes

Used in display fireworks (aerial salutes), Military artillery simulators and noise/flash diversion Ary devices (flash bangs).

60
Q

Primary high explosives are used in

A

Detonators/blasting caps and are used to initiate secondary high explosives.

Extremely sensitive to initiation by friction, shock, static electricity, heat (flame), Or combination of these.

61
Q

Electronic blasting caps/detonators

A

High explosive and are used as initiators.

62
Q

What is the net explosive weight of Booster, dynamite, emotions, ANFO

A

Gross weight. 100%

63
Q

net explosive weight of detonators

A

1.5 pounds of HE per 1000

64
Q

Net explosive weight of detonating cord

A

9 pounds of HE per 1000 feet (50 to 60 grains/feet) (For others sizes, grains per feet divided by 6.7 equals pounds per 1000 feet). For example 1000 feet of 20 green cord equals 20÷6.7=2.985
