Combustible dust (zirconium) explosion

In 2010, an explosion and fire occurred at the AL Solutions plant, which processed titanium and zirconium. Both metals in the form of dust are explosive. At elevated temperatures, they can react with water, additionally generating explosive hydrogen. For this reason, type D extinguishing powders are recommended. Nevertheless, four audits carried out over several years by consulting and insurance companies did not indicate that the water spraying system used in the plant constitutes an inappropriate extinguishing method. This example shows the continuing need to spread knowledge in the field of explosion and fire safety. Some of these audits also praised the method of cleaning up the remaining dust by flushing them with a water jet. Although metals over time are covered with oxides, which normally make it difficult to react with water, at AL Solutions we have had to deal with a freshly ground material that has not yet formed such a protective barrier. As research has shown, a small amount of hydrogen is generated in this situation, increasing the energy of the dust explosion. More on: https://www.grupa-wolff.com/case-stud...
