This is referred to as smoke explosion or fire gas ignition depending on the severity of the combustion process. A hot rich flashover occurs when the hot smoke with flammable gas ratio above the upper limit of flammability range and temperature higher than the ignition temperature leaves the compartment. Upon dilution with air it can ...
A burning candle. Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] At a certain point in the combustion reaction, called the ignition point, flames are produced.
A fire whirl, fire devil or fire tornado is a whirlwind induced by a fire and often (at least partially) composed of flame or ash. These start with a whirl of wind , often made visible by smoke , and may occur when intense rising heat and turbulent wind conditions combine to form whirling eddies of air.
The development of napalm was precipitated by the use of jellied gasoline mixtures by the Allied forces during World War II. [5] Latex, used in these early forms of incendiary devices, became scarce, since natural rubber was almost impossible to obtain after the Japanese army captured the rubber plantations in Malaya, Indonesia, Vietnam, and Thailand.
Flames of charcoal. A flame (from Latin flamma) is the visible, gaseous part of a fire.It is caused by a highly exothermic chemical reaction made in a thin zone. [1] When flames are hot enough to have ionized gaseous components of sufficient density, they are then considered plasma.
Disaster Girl is a name given to a meme featuring a young girl staring at the camera with a structure fire behind her. [ 1 ] [ 2 ] [ 3 ] The girl in the photo, Zoë Roth, was four years old when the photo was taken in 2004.
From 1999 to 2020, the number of alcohol-related deaths has nearly doubled, according to Florida Atlantic University study. A researcher and addiction specialists discuss the risk factors.
In most cases of structural firefighting, windows are broken or removed from the outside of the building to provide efficient horizontal ventilation. A 4x4 foot opening may also be cut into the roof directly over the fire room. This allows hot smoke and gases to escape through the opening, returning the conditions inside the room to normal.
