Flameproof is a term used to describe materials that are resistant to fire, combustion and flames. Its antonyms include words such as flammable, combustible, inflammable, ignitable and explosive. These words suggest a material or substance that can easily catch fire or ignite when exposed to heat or flames. For instance, materials such as gasoline, alcohol, and paper are considered highly flammable. Unlike flameproof materials, flammable substances can cause serious harm or damage when exposed to flames, leading to explosions, fires, and loss of property. Therefore, it is crucial to handle flammable materials with extreme caution and keep them away from open flames or heat sources.
