Alum. Powder?

[ad_1]

Aluminum powder is a highly flammable powder created by grinding aluminum into fine grains. In the past, this flammable metal powder was used in photography to create bright flashes during a photo session. Today, it is one of the tools used in various applications of pyrotechnics, including the creation of fireworks displays.
Due to the combustible nature of powdered aluminum products, there are a number of restrictions on its sale. In some countries, the powder is only available for purchase to businesses. Even in countries where it can still be purchased by individuals, it’s not uncommon for manufacturers to sell the powder only to suppliers, who then sell small batches to residential customers.

While the use of aluminum powder as a flash powder is the compound’s most readily recognized function, it can also be employed in the creation of wood furniture and flooring. Primarily used as a marquetry compound, it can easily be used to place cut pieces of wood and also fill any small gaps that may be present in the joints. Since only a small amount of powder is required for functions of this type, the possibilities for ignition are somewhat limited.

Aluminum powder is best handled by professionals who know how to use the compound under controlled circumstances. An example are companies that produce fireworks displays for sporting and municipal events. When handled correctly, the powder can not only produce spectacular visual effects, but also provide the loud booming sounds that often add to the entertainment value of a fireworks display. Pyrotechnic professionals typically wear protective clothing, including gloves and safety goggles, in order to minimize direct exposure to skin and eyes, and also provide a barrier in case the powder ignites prematurely.

While suppliers using aluminum often take a number of precautions, the highly explosive nature of the powder can cause accidents in the most controlled environments. If the dust gets into your eyes, rinse them immediately and continuously for at least 15 minutes. In the meantime, emergency medical assistance should be summoned immediately.

Dust burns should also be treated with a continuous stream of cold water to cool them down and gently wash away any residue. If the dust is accidentally inhaled, the individual should be removed to fresh air immediately and, in extreme situations, oxygen should be given. In all circumstances, medical attention should be sought as quickly as possible to minimize the possibility of any sort of permanent damage.
