This is for handling aluminum
Aluminum as a solid is very safe; although non-nutritious (your body does not require it), its accumulation in tissues is apparently not directly harmful. Individuals who work years of their lives in handling aluminum have no higher incidence of Alzheimer's disease than those that do not. As a powder- particularly very fine powders- aluminum is extremely hazardous with respect to its combustibility, and is used in fireworks (sparklers, for example). When it burns, it is extremely hot, and extinguishing it should not be attempted without training and the correct tools- usually salt or Purple K extinguishing agent. However, it burns so quickly that it will usually be out before attempts can be made.
