What are examples of low explosives?
Examples of Low Explosives include: Black Powder, Smokeless Powder, and Flash Powder.
What are low explosives used for?
Low explosives are normally employed as propellants. Included in this group are petroleum products such as propane and gasoline, gunpowder (including smokeless powder), and light pyrotechnics, such as flares and fireworks, but can replace high explosives in certain applications, see gas pressure blasting.
Is black powder a low explosive?
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.
Is gasoline a low explosive?
The lower flammable limit or lower explosive limit (LFL or LEL) of gasoline is 1.4 percent; the upper flammable limit or upper explosive limit (UFL or UEL) is 7.6 percent. This means that gasoline can be ignited when it is in the air at levels between 1.4 and 7.6 percent.
What are division 1.3 explosives?
Division 1.3 consists of explosives that have a fire hazard and either a minor blast or minor projection hazard or both, but not a mass explosion hazard. Examples are sodium picramate, some liquid and solid propellants, and some rocket motors. Division 1.4 consists of explosives that present a minor blast hazard.
What is the difference between high and low explosive?
Explosives are classified as low or high explosives according to their rates of decomposition: low explosives burn rapidly (or deflagrate), while high explosives undergo detonations. No sharp distinction exists between low and high explosives, because of the difficulties inherent in precisely observing and measuring rapid decomposition.
What are the most widely used low explosives?
The most widely used explosives in the low-explosive group are black powder and smokeless powder. Black powder is a mixture of potassium or sodium nitrate, charcoal, and sulfur. Smokeless powder consists of nitrated cotton (nitrocellulose) or nitroglycerin and nitrocellulose.
Which explosive is more powerful?
The most powerful known condensed (i.e. solid) explosive is probably octonitrocubane. It has an R.E. of 2.38 meaning it is about 2.38 times as powerful as TNT. It has a detonation speed of an incredible 10,600 meters/sec.
What does a low order explosive material?
A low order explosive is a low explosive substance, for example gunpowder or a pyrotechnic composition, whereas a low order explosion is the functioning of that substance as intended, slow burning in the open, but speeded up if contained until their container bursts, just like a fireworks banger or firecracker.
