Wet chemical fire extinguishers typically use potassium acetate-based agents, though formulations vary by product.
How Does a Wet Chemical Fire Extinguisher Put Out a Fire?
Wet chemical fire extinguishers are designed to tackle fires involving cooking oils and fats, common in commercial kitchens.
The extinguishing agent cools the hot oil or fat and forms a protective layer on its surface. This layer helps prevent oxygen from reaching the fuel, suppresses the flames, and reduces the risk of re-ignition.
