What do explosive engineers do?
Some of the topics that explosives engineers study, research, and work on include: Development and characterization of new explosive materials in various forms. Analysis of the physical process of detonation. Explosive generated shock waves and their effects on materials.
What element is common to many explosives?
All explosives must contain both oxidizing and reducing agents. Strong oxidizing agents require the use of the most electronegative elements nitrogen, oxygen, fluorine, and chlorine. Therefore, one common aspect of HE compositions is a large percentage of the more electronegative elements nitrogen and oxygen.
What are explosions made of?
TNT is composed of the elements carbon, oxygen and nitrogen. When TNT explodes it forms several covalent gases: CO, CO2 and N2 that are very stable. The production of these very low energy (stable) bonds means that a great deal of energy is released. It should be noted that most explosives contain these same elements.
How much do EOD specialists get paid?
The typical US Army EOD Technician salary is $54,016. EOD Technician salaries at US Army can range from $31,711 – $81,743.
What is the fastest explosive?
Octanitrocubane has a detonation velocity of 10,100 m/s, making it the fastest known explosive. Small amounts have been synthesized in the laboratory, but not enough for performance testing as an explosive.
What is the strongest explosive?
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.
Who made the first explosive?
Alfred Nobel, in full Alfred Bernhard Nobel, (born October 21, 1833, Stockholm, Sweden—died December 10, 1896, San Remo, Italy), Swedish chemist, engineer, and industrialist who invented dynamite and other more powerful explosives and who also founded the Nobel Prizes.
Why is dynamite called TNT?
By combining the stabilized nitroglycerin paste with a detonator he’d invented earlier, Nobel had his practical explosive. He called it dynamite after the Greek word for power, dynamis. TNT, in contrast to nitroglycerin, is very difficult to detonate.
What is the most dangerous explosive?
Like all azides, it reacts with water to emit explosive, highly toxic hydrogen azide. Azidoazide azide has been called “the most dangerous explosive material in the world.” It is also No. 3 in K. S. Lane’s list “The 10 Most Dangerous Chemicals Known to Man”.
Is pure nitrogen explosive?
Flames are extinguished and animals die in an atmosphere of pure nitrogen – so it was once known as “azote”, Greek for “lifeless”. And yet this colourless, odourless gas, making up 78% of the atmosphere, has a highly explosive nature.
How does an explosion kill?
Based on this, one can list the ways one can be killed by an explosion: Primary – If close enough to an explosive overpressure, the blast will cause the most catastrophic damage. Decapitation, dismemberment, traumatic brain injury will all kill one instantly to within seconds. Physics wises, this is due to acceleration.
How are explosions and burning different?
A fire occurs when there is chemical reaction of a substance (fuel) combining with an oxidizer to release energy in the form of heat or light. An explosion is a violent release of energy caused by a physical or chemical reaction. It is accompanied by a rapid increase in pressure and usually temperature.
How long is EOD training in the Army?
EODs spend the standard ten weeks in boot camp, formally known as Basic Combat Training (or just “Basic”) and 39 weeks in Advanced Individual Training (AIT) at Fort Lee in Virginia. Their AIT is longer than a lot of other Army jobs since the work these soldiers do requires such a high level of skill and expertise.
How many EOD techs have died?
Since 9/11, 131 EOD technicians have died in combat and another 250 have sustained major physical injuries including lost eyesight, lost limbs, paralysis and major burns, but it is the numbers that aren’t tallied that are now most alarming to Falke and many others.
Do bomb suits work?
EOD technicians wear bomb suits during reconnaissance, ‘render safe’ or disruption procedures on potential or confirmed explosive threats. Such suits must provide a tremendous degree of protection from fragmentation, blast overpressure, thermal and tertiary effects should the threat device detonate.
How much do bomb disposal experts get paid?
3. Bomb disposal diver. Typical salary: In the private sector you can earn up to £60,000 a year in the UK and £100,000 outside the UK, working just two months out of every three. Supervisors will command an extra £50 to £100 a day on top.
Where do Explosive workers work?
Positions for these workers are located in construction companies, airlines and airplane manufacturers, rock and gravel quarries, the oil and gas industry, and the military. Explosives workers generally need a high school diploma or equivalent.
What does a blaster do?
A blaster, also known as an explosives worker, uses explosives and detonators to demolish structures or remove earth in a quarry, mine, or similar site. You then drill holes in rock or structural supports, pack the holes with the required explosives, and oversee the detonation.
What is an explosive specialist?
Job Description for Explosives Workers, Ordnance Handling Experts, and Blasters : Place and detonate explosives to demolish structures or to loosen, remove, or displace earth, rock, or other materials. May perform specialized handling, storage, and accounting procedures.
How fast is an explosion mph?
At 50 seconds after the explosion, when the fireball is no longer visible, the blast wave has traveled about 12 miles. It is then traveling at about 784 miles per hour, which is slightly faster than the speed of sound at sea level.
| Peak overpressure | Maximum Wind Speed |
|---|---|
| 10 psi | 294 mph |
| 5 psi | 163 mph |
| 2 psi | 70 mph |
What is the most powerful chemical?
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.
What happens to your body after an explosion?
The main direct, primary effect to humans from an explosion is the sudden increase in pressure that occurs as a blast wave passes. It can cause injury to pressure- sensitive human organs, such as ears and lungs.
Is it illegal to own dynamite in Namibia?
Under federal explosives law, it is illegal to manufacture, store, distribute, receive or transport explosive materials without a federal explosives license or permit (FEL/FEP).
How is dynamite used today?
Today, dynamite is mainly used in the mining, quarrying, construction, and demolition industries. Dynamite is still the product of choice for trenching applications, and occasionally used as a cost-effective explosive booster for ANFO charges.
Why can’t we use nitrogen in the atmosphere?
Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive.
Why do we need nitrogen?
Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms. A process called the nitrogen cycle makes this happen.
