A slow fire is a term used in library and information science to describe paper embrittlement resulting from acid decay. The term is taken from the title of Terry Sanders 's 1987 film Slow Fires: On the preservation of the human record.

This has been referred to as the slow fire. A statement submitted to the House of Representatives estimated that there were 80 million brittle books in North American libraries ...

In 1998, it was proposed jointly by librarians from Jagiellonian Library and chemists from the Faculty of Chemistry of Jagiellonian University, "to save the heritage of Polish culture in the library and archives ...
High-severity fires will burn into the crowns of the trees and kill most of the dominant vegetation. Crown fires may require support from ground fuels to maintain the fire in the forest canopy (passive crown fires), or the fire may burn in the canopy independently of any ground fuel support (an active crown fire).
The fire lit in this scenario is categorized as a class B fire (fire from flammable liquids), while the fire from burning paper (banknote) is categorized as class A. [1] The alcohol-water mixture flame can be hard to detect, so sodium chloride can be added to give the flames an orange-yellow color.
Like the Fire Sermon, this discourse has a central metaphor related to fire – likening our physical and mental apparatus to hot embers (Pali: kukkuḷa) – and concludes with the well-instructed noble disciple becoming disenchanted with, dispassionate about and liberated from these burning constituents.

If a fire is compartmentalized and most or all of the oxygen has been burned up, there is a high risk of backdraft if something such as a window or door is opened. Introducing oxygen to a low burning fire can be devastating as it will ignite all of the oxygen along the way. [27]
