Chemical reactions involving thermal runaway are also called thermal explosions in chemical engineering, or runaway reactions in organic chemistry.It is a process by which an exothermic reaction goes out of control: the reaction rate increases due to an increase in temperature, causing a further increase in temperature and hence a further rapid increase in the reaction rate.

A thermal imaging camera (colloquially known as a TIC) is a type of the thermographic camera used in firefighting. By rendering infrared radiation as visible light , such cameras allow firefighters to see areas of heat through smoke, darkness, or heat-permeable barriers.
A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the progenitor , either collapses to a neutron star or black hole , or is completely destroyed to form a diffuse nebula .

Most modern infantry assault rifles fire from a closed bolt, meaning that when ready to fire, there is a round in the chamber of the barrel and the bolt and working parts are in the forward position, closing the breech. Squeezing the trigger releases the striker or hammer, firing the cartridge in the chamber.
Responding for the first time to a high-voltage battery electric vehicle fire, the firefighters first cooled the vehicle then moved it into a container which they then filled with water. [146] On September 3, 2021, a VW e-Golf caught fire in Dumbrăviţa, Romania. The firefighters used a container to submerge the car in water. [147]
Mars may have experienced the opposite of a runaway greenhouse effect: a runaway refrigerator effect. Through this effect, a runaway feedback process may have removed much carbon dioxide and water vapor from the atmosphere and cooled the planet. Water condenses on the surface, leading to carbon dioxide dissolving and chemically binding to minerals.
