Which is the preferred method to overhaul a trash bin fire?

Using Class A foam to saturate all the fuel is the preferred method to overhaul a trash bin fire because Class A foam is specifically designed to penetrate and smother combustible materials. This type of foam enhances the water's effectiveness by reducing surface tension, allowing it to spread more readily over and saturate the burning materials. By applying Class A foam, firefighters can effectively suppress the fire, cool down the burning materials, and prevent re-ignition, ensuring that the fire is fully extinguished and reducing the risk of fire spread.

In the context of a trash bin fire, where the contents might be varied and could include plastics, paper, or other materials that might reignite, using Class A foam not only addresses the immediate fire but also helps in managing the potential for hazardous smoke that could arise from burning refuse. This approach is efficient, effective, and aligns with best practices for fire extinguishment in similar scenarios.
