The Firevase is a modern version of this technology made of polyvinyl chloride (PVC) and filled with liquid potassium carbonate. The firevase, designed to also hold flowers, was created as part of a fire safety project in South Korea where an estimated 10,000 residential fires occur every year. 100,000 firevases were handed out to households in fire-prone areas between September and December 2018.
The AFO Fire Extinguisher ball, thought to be made of a foam casing wrapped in PVC, does not need to be thrown at a fire as it will self-activate when it comes into contact with the flames. It also produces a loud sound which will serve as an alarm for people nearby. Some people use it in the engine bay of their vehicles where it would prevent any fire outbreak before it may otherwise be detected.
