What is an example of a high explosive?
High Explosives – explosive materials that can be caused to detonate by means of a blasting cap. A few examples of high explosives would be boosters, detonators, dynamite, water gels/slurries, and emulsions.
What are some characteristics of high explosives?
High explosives are materials that are characterized by a very high rate of reaction, high pressure development, and the presence of a detonation wave. The guideline applies to the following explosives: blasting explosives in bulk or in packaged form, e.g.; ANFO (ammonium nitrate / fuel oil);
What does highly explosive mean?
Definition of high explosive : an explosive (such as TNT) that generates gas with extreme rapidity and has a shattering effect.
What are the two types 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.
What are the classification of explosives according to its sensitivity?
Explosives are further classified into primary, secondary, and tertiary explosives depending on its level of sensitivity to external stimuli. Standardized testing evaluates the sensitivity in terms of friction, impact, heat, shock and based on these results, explosives are classified accordingly.
How do high explosives work?
High explosives consist of materials that typically combine the reacting elements in the same molecule. This allows them to react much faster, and they “detonate.” Detonation involves supersonic shock waves that pass through the material, causing chemistry that happens quite a bit faster than burning.
What are low explosives?
Low explosives are mixtures of chemicals that burn very rapidly, but subsonically (as opposed to supersonically), meaning that they “deflagrate.” They consist typically of fuel and an oxidizer. The black powder used in fireworks is one example of a low explosive.
What is an explosive hazard?
The OSHA Laboratory Standard defines an explosive as a chemical that causes a sudden, almost instantaneous release of pressure, gas, and heat when subjected to sudden shock, pressure, or high temperature. Under the Department of Transportation (DOT) hazard class system, explosives are listed as hazard class 1.
What is the importance of explosives analysis?
Analysis of explosives in storage is important for assessing the purity of their components, the uniformity of composition, and the various decomposition products.
What are the differences between low explosives and high explosives?
Low explosives are mixtures of chemicals that burn very rapidly, but subsonically (as opposed to supersonically), meaning that they “deflagrate.” They consist typically of fuel and an oxidizer. High explosives consist of materials that typically combine the reacting elements in the same molecule.
What is the scientific definition of an explosion?
An explosion is defined as the rapid increase in volume and release of energy in an extreme manner. Bodurtha explains in his book “Industrial Explosion Prevention and Protection,” “an explosion is the result, not the cause, of a rapid expansion of gases. It may occur from physical or mechanical change.”
