Can powder catch on fire

Yes, powder can catch fire under certain conditions. Flammable powders, such as those made from certain metals, organic materials, or certain chemicals, can ignite if they are dispersed in the air and exposed to an ignition source, like a spark or flame. The fine particles can create a dust cloud that increases the surface area, making ignition more likely. It's essential to handle such powders with caution to prevent fire hazards.
