What are low explosives sensitive to?
The low explosives exert more of a pushing or heaving effect (when confined), and are generally used as propellant powders. Low explosives are sensitive to heat, friction, and shock. Examples of Low Explosives include: Black Powder, Smokeless Powder, and Flash Powder.
Which are more sensitive explosives?
Straight Dynamite – Nitroglycerin in an absorbent, with velocities between 10,000 and 20,000 feet per second. This dynamite is the most sensitive of all commercial explosives.
What are examples of low explosives?
Low Explosives – explosives that are characterized by deflagration or a low rate of reaction and the development of low pressure. Black powder, smokeless powder, safety fuse, and squibs/igniters are classified as low explosives.
What are two examples of low 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 are the three types of explosives?
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 are the most widely used low explosives?
Consider for instance black powder, the most primitive form of gunpowder and the quintessential low explosive. In black powder, charcoal and sulphur are the fuel, and postassium nitrate (KNO3) is the oxidizing agent.
What are primary explosives sensitive to?
Primary explosives are very sensitive materials that can be easily ignited by small stimuli of heat, impact, friction, and electrostatic. Very small amount of energy is needed to initiate such material; it is considered to be the materials that are more sensitive than PETN.
What is high and low explosive?
Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be “high explosives” and materials that deflagrate are said to be “low explosives”.
Why is ni3 explosive?
It is an extremely sensitive contact explosive: small quantities explode with a loud, sharp snap when touched even lightly, releasing a purple cloud of iodine vapor; it can even be detonated by alpha radiation….Nitrogen triiodide.

What is the most powerful explosive in the world?
PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
Can dust cause an explosion?
Dust can collect on surfaces such as rafters, roofs, suspended ceilings, ducts, crevices, dust collectors, and other equipment. When the dust is disturbed and under certain circumstances, there is the potential for a serious explosion to occur. The build-up of even a very small amount of dust can cause serious damage.
What is the difference between primary and secondary explosives?
Primary explosives detonate by ignition from some source such as flame, spark, impact, or other means that will produce heat of sufficient magnitude. Secondary explosives require a detonator and, in some cases, a supplementary booster. A few explosives can be both primary and secondary…
