Alikabok ng aluminyo, may kakayahang sumabog, ay nakategorya bilang isang Class II nasusunog na materyal. Ito ay nagrereact sa tubig upang makabuo ng hydrogen gas at init.
Sa kaso ng isang pagsabog ng alikabok ng aluminyo, hindi advisable ang paggamit ng tubig para sa extinguishing. Foam fire extinguishers ang inirerekomendang opsyon (lalo na sa aluminum profile processing) as the foam isolates the flames from the air. This is due to aluminum’s chemical reaction with water, which produces hydrogen gas, rendering water ineffective for fire suppression. There has been an incident where an explosion was triggered by attempting to extinguish burning aluminum dust with water.
