Dry sand is an effective smothering agent, but only on relatively level and flat surfaces. The explosion destroyed the entire laboratory and left a crater 30 metres in diameter." 362 comments. ZIMSEC O Level Combined Science Notes: Experiment: The reaction of metals and water Aim: Investigating and Observing the reactions of metals and water Materials: calcium, magnesium, zinc, lead, iron, copper, beaker, test tubes, filter funnel, water, splint, burner, universal indicator 13.1k. 12.2k. Description of the Magnesium Dust Explosion: On May 2, the Lansing State Journal reported of a fire and series of explosions at the Meridian Magnesium Products of America Facility in Eaton Rapids, Michigan. Water solubility of magnesium hydroxide is 12 mg/L. Fire/Explosion. Magnesium Dust is Combustible and is an Explosion Hazard: When most people think of controlling dust in the workplace, they think of taking steps to avoid inhaling dusts to prevent health problems. The hydrogen gas produced intensifies the fire. Aftermath of a grain dust explosion near my hometown yesterday (08/25/2020). Burning or molten magnesium metal reacts violently with water. https://stonehousesafety.com/ss-case-studies/magnesium-dust-explosion ... Laing, Michael. However, the accumulation of combustible dusts in the workplace can lead to far greater consequences. Explosive meeting of molten aluminium and water. Other magnesium compounds are clearly more water soluble, for example magnesium carbonate (600 mg/L). share. Magnesium sulphate adds a bitter flavour to water, and has a water solubility of 309 g/L at 10 o C. Why is magnesium present in water? No injuries or deaths reported. Magnesium is capable of reducing water and releasing highly flammable hydrogen gas: Mg (s) + 2 H 2 O (l) → Mg(OH) 2 (s) + H 2 (g) Therefore, water cannot extinguish magnesium fires. When working with powdered magnesium, safety glasses with welding eye protection are employed, because the bright white light produced by burning magnesium contains ultraviolet light that can permanently damage eyes.
