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..
How does an explosion occur?
An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. … Subsonic explosions are created by low explosives through a slower combustion process known as deflagration.
Is TNT and dynamite 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 does TNT transport stand for?
Thomas Nationwide TransportThomas Nationwide Transport, commonly known by its TNT acronym, and in its later years as TNT Limited, was an Australian logistics and transport company. … Founded in 1946, it was taken over by KPN in 1996 and in 1998 became part of the TNT Post Group.
What causes the greatest damage in an explosion?
Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down.
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.
What are the most powerful explosives?
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 was the biggest explosion ever?
The Messines mines detonation killed more people than any other non-nuclear man-made explosion in history.
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 does an explosion kill you?
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 can cause an explosion in a house?
Some common causes include:Improper use of gas furnaces, stoves or other gas appliances.Gas appliances that have been poorly or incorrectly installed.Old, rusty gas lines or ones that are damaged that run from the street into your home.Defective gas-operated equipment.More items…
What causes TNT to explode?
TNT is explosive for two reasons: 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.
