👉 Fire fluid, also known as firefighting foam or fire suppressant, is a specialized chemical mixture designed to control and extinguish fires. It typically consists of water, surfactants (chemicals that reduce surface tension), and sometimes other additives like foam-forming agents or fire retardants. When applied to a fire, the surfactants break down the surface tension of water, allowing it to spread more evenly and penetrate the fire more effectively. The foam created by these chemicals traps oxygen away from the fire, cutting off its supply of oxygen and thus smothering it. This process helps to cool the fire, prevent re-ignition, and protect surrounding structures. Fire fluids are crucial in various firefighting scenarios, from residential fires to large industrial accidents.
