A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas , methane , propane , butane .
For an explosion to occur, there must be a rapid, forceful expansion of matter. There are numerous ways this can happen, both naturally and artificially, such as volcanic eruptions, or two objects striking each other at very high speeds, as in an impact event. Explosive volcanic eruptions occur when magma rises from below, it has dissolved gas ...
Lab demonstration with burning lycopodium powder. A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen.
The faulty procedure used caused natural gas to build up in homes within a matter of minutes. Multiple explosions and fires were reported over a very short period of time in the towns of Lawrence, Andover, and North Andover beginning about 4:15 pm . [9] Through the evening emergency crews responded to between 40 and 80 fires.
A gas leak refers to a leak of natural gas or another gaseous product from a pipeline or other containment into any area where the gas should not be present. Gas leaks can be hazardous to health as well as the environment. Even a small leak into a building or other confined space may gradually build up an explosive or lethal gas concentration. [1]
The massive explosion at the Sandman Signature Hotel in downtown Fort Worth, suspected as a gas leak, may be part of a worsening trend across the US. Gas leak explosions are happening more often ...
A vehicle loaded with gas exploded and set off an inferno that burned homes and warehouses in Kenya's capital, killing at least three people and injuring more than 270, officials said Friday, with ...
The main mechanism of detonation propagation is of a powerful pressure wave that compresses the unburnt gas ahead of the wave to a temperature above the autoignition temperature. In technical terms, the reaction zone (chemical combustion) is a self-driven shock wave where the reaction zone and the shock are coincident, and the chemical reaction ...
