What are the 3 classification of explosives?
There are 3 classes of explosive materials:
- (a) High explosives (for example, dynamite, flash powders, and bulk salutes);
- (b) Low explosives (for example, black powder, safety fuses, igniters, igniter cords, fuse lighters, and “display fireworks”, except for bulk salutes); and.
What is a Class A explosive?
“Class A explosives.” Possessing, detonating, or otherwise maximum hazard; such as dynamite, nitroglycerin, picric acid, lead azide, fulminate of mercury, black powder, blasting caps, and detonating primers.
What are the two classes of high explosives?
There are two major categories, high explosives and low explosives. High explosives are further divided into initiating, or primary, high explosives and secondary high explosives.
Is PETN a primary explosive?
PETN is a second- ary explosive and as such is not as sensitive as primary explosives such as lead azide. Cast primers of PETN are also supplied as shaped charges. RDX – RDX (cyclotrimethylenetrinitramine) is second in strength to nitroglycerin among common explosives substances.
What type of smell does ANFO present?
A telltale sign of an ANFO bomb, for instance, are its signature residues and the lingering smell of ammonia following a blast. This helps law enforcement authorities determine the cause of the blast, but, because the odor is emitted after the blast, it does little to prevent such an attack.
How many classes of explosives are there?

| Hazard type | Explanation |
|---|---|
| Hazard Type 1 | a mass explosion is one in which the entire body of explosives explodes as one |
| Hazard Type 2 | |
| Hazard Type 3 | ie those explosives which give rise to considerable radiant heat or which burn to produce a minor blast or projection hazard |
Is PETN a military grade explosive?
A military grade explosive, PETN is not easily available and has been used in the past by groups such as Al Qaeda for making bombs. PETN or Pentaerythritol tetranitrate is one of the most dangerous plastic explosive. The substance is available in black market, and belongs to the same family as nitroglycerin.
What is the hazard class or division for PETN?
Hazard Class or Division: 1.1D; Pentaerythrite tetranitrate (Pentaerythritol tetranitrate; PETN), with not less than 7% wax, by mass. [United Nations; Recommendations on the Transport of Dangerous Goods.
What is the chemical formula for PETN?
PETN has the chemical formula C5H8N4O12. It is formed by reacting pentaerythritol (C5H12O4), an alcohol commonly used in paints and varnishes, with nitric acid (HNO2). The reacting solution is chilled to precipitate the PETN.
What are the characteristics of a PETN explosion?
Its basic explosion characteristics are: Explosion energy: 5810 kJ/kg (1390 kcal/kg), so 1 kg of PETN has the energy of 1.24 kg TNT. Critical diameter (minimal diameter of a rod that can sustain detonation propagation): 0.9 mm for PETN at 1 g/cm 3, smaller for higher densities (other value: 1.5 mm)
