For extinguishing aluminum powder fires, dry powder extinguishers are recommended. Classified as Class D extinguishers, they are specifically tailored for combating metal fires.
In cases of self-ignited aluminum powder, utilizing a carbon dioxide dry powder extinguisher is effective. Due to its greater density than air, carbon dioxide creates a barrier against oxygen, thereby facilitating fire suppression. It is crucial to avoid using water on aluminum powder fires. Being a heavy metal, aluminum powder reacts with water at high temperatures, exacerbating the heat release and accelerating combustion, potentially causing more significant damage.
