The generation of heat in large quantities accompanies most explosive chemical reactions. The exceptions are called entropic explosives and include organic peroxides such as acetone peroxide. [6] It is the rapid liberation of heat that causes the gaseous products of most explosive reactions to expand and generate high pressures. This rapid ...
The most widely used explosives are condensed liquids or solids converted to gaseous products by explosive chemical reactions and the energy released by those reactions. The gaseous products of complete reaction are typically carbon dioxide, steam, and nitrogen. [18]
There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date.
The scale of the damage resembles other blasts involving the chemical compound commonly used as an agricultural fertilizer. Fireworks, ammonium nitrate likely fueled Beirut explosion Skip to main ...
Online videos of the disaster's initial moments show sparks and lights inside the smoke rising from the blaze, just prior to the massive blast
The cause was an explosion following a propane tank leak. [7] On March 1, 1965, the LaSalle Heights Disaster occurred when a gas line fractured in a low-cost residential neighborhood near Montreal, Quebec, killing 28 people and injuring dozens. On January 9, 1968, in Reading, Pennsylvania, an explosion killed nine persons and demolished two ...
Blast injuries can cause hidden sensory [11] and brain damage, with potential neurological and neurosensory consequences. It is a complex clinical syndrome caused by the combination of all blast effects, i.e., primary, secondary, tertiary and quaternary blast mechanisms.
A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction, pressure, sound, light). Though different contact explosives have varying amounts of energy sensitivity , they are all much more sensitive relative to other kinds of explosives.
