What actually kills you in an explosion?
Explosive shock waves can cause situations such as body displacement (i.e., people being thrown through the air), dismemberment, internal bleeding and ruptured eardrums.
Shock waves produced by explosive events have two distinct components, the positive and negative wave..
What is the blast radius of TNT?
Negative phase Time [msec] Page 6 Fundamental Disaster Management 7-6 for serious injury of 10-30 meters. In contrast, the lethal blast radius for a car containing 455 kg of TNT is 60 meters, with a serious injury range of over 500 meters.
How does explosion occur?
The transition from combustion to explosion is caused by an acceleration of the reaction, induced either by a rise in temperature or by increasing lengths of the reaction chain. The first is called thermal explosion, and the second is called chain explosion.
Are dynamite and TNT the same thing?
Dynamite is not the same thing as TNT. You’ve probably heard people say “TNT” and “dynamite” in a conversation as though they were the same thing. … But TNT (or 2,4,6,-trinitrotoluene, to use its chemical name) is not one of those components. Instead, the active explosive in dynamite is a chemical called nitroglycerin.
What are the main effects of explosion?
Explosion effects generally include those of overpressure, thermal effects, energized projectiles (fragments, debris, and missiles), ground shock, and cratering.
How many PSI can kill you?
The threshold value for lung damage is 12 psi and fatal effect is 40 psi (Glover, 2002). At a pressure of about 35 kilopascals (5 psi), the human eardrum may rupture. With an overpressure of 100 kPa (14 PSI) almost all eardrums will be ruptured.
What makes an explosion happen so quickly?
lots of heat is released, which quickly causes a rapid increase in the volume of the gases being formed, creating a shock wave—a series of air waves that move fast—typical of explo- sions. More than 200 dust fires and explosions have occurred in U.S. industrial facilities during the past 25 years.
What is the fastest explosive?
OctanitrocubaneOctanitrocubane 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.
How much PSI is in a nuclear bomb?
Overpressure ranges from 1 to 50 psi (6.9 to 345 kilopascals) of a 1 kiloton of TNT air burst as a function of burst height.
What is the most powerful bomb in the world?
Tsar BombaTsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.
Was Chernobyl or Hiroshima worse?
“Compared with other nuclear events: The Chernobyl explosion put 400 times more radioactive material into the Earth’s atmosphere than the atomic bomb dropped on Hiroshima; atomic weapons tests conducted in the 1950s and 1960s all together are estimated to have put some 100 to 1,000 times more radioactive material into …
How long until Chernobyl is safe?
20,000 yearsMore than 30 years on, scientists estimate the zone around the former plant will not be habitable for up to 20,000 years. The disaster took place near the city of Chernobyl in the former USSR, which invested heavily in nuclear power after World War II.
Is Chernobyl safe now?
Despite all the effort invested in the area to make Chernobyl safe, its clean-up still continues today as scientists from the State Radiation Ecological Reserve frequently test radiation levels to check whether people and wildlife can safely return to the area again.
Can a person survive an explosion?
The human body can survive blasts of sudden pressure of 20-40 psi, but it’s not the only thing receiving that pressure. The pressure radiates outward from the blast in all directions. … Even if someone were to survive a blast – they would most likely be killed by being knocked into their surroundings.
Is Hiroshima still radioactive?
Among some there is the unfounded fear that Hiroshima and Nagasaki are still radioactive; in reality, this is not true. Following a nuclear explosion, there are two forms of residual radioactivity. … In fact, nearly all the induced radioactivity decayed within a few days of the explosions.
What is the maximum air pressure a human can withstand?
On Earth, the limit is around 18–19 km (11–12 mi; 59,000–62,000 ft) above sea level, above which atmospheric air pressure drops below 0.0618 atm (6.3 kPa, 47 mmHg, or about 1 psi). The U.S. Standard Atmospheric model sets the Armstrong pressure at an altitude of 63,000 feet (19,202 m).
Can gasoline explode without a spark?
That’s a lot of explosive energy stored in a typical, full gas tank! … This could blow a hole in the gas tank and cause the release of fumes. You could heat the gasoline up to a high enough temperature that it could ignite spontaneously: without even a spark.
How fast does an explosion travel?
Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around 1600 m/s to 1800 m/s but can be as high as 3000 m/s. Solid explosives often have detonation velocities ranging beyond 4000 m/s to 10300 m/s.
What happens to the human body when a bomb explodes?
The blast wave causes damage to more extensively to air-filled organs. The resulting barotrauma can affect the lungs, auditory organs, the eye, brain, and gastrointestinal tract. Blast belly – injury causing abdominal hemorrhage and perforation (immediate and delayed).
Are explosions always used to destroy things?
Explosions occur directly in pieces of technological equipment during milling, drying, pneumatic or mechanical transport, storage and filtration, and they usually have fatal consequences. Unfortunately organic substance explosion do not only destroy the equipment, they also often kill.
Can air pressure kill you?
Here are a few ways that compressed air can kill or seriously injure a person: Compressed air blown into the skin can obstruct an artery and result in an embolism. Inhaled compressed air can rupture your lungs or esophagus. Compressed air blown into the ear can rupture eardrums and cause brain damage.
