👉 Blow fluid, also known as firefighting foam or fire suppressant, is a specialized chemical mixture used in firefighting to control and extinguish fires. It typically consists of water, a surfactant (often a polymer), and other additives like carbon dioxide or inert gases. The primary function of blow fluid is to create a barrier between the burning material and oxygen, effectively smothering the fire by cutting off its supply of fuel. Additionally, the foam helps to cool the fire and prevent re-ignition by reducing the surface area exposed to heat. The surfactant in the fluid reduces the surface tension of water, allowing it to form stable, large bubbles that can carry water over longer distances and penetrate deeper into the fire, enhancing its effectiveness.
