A Good Dry Powder to Suppress High Building Fires

In our daily life there are more and more super high buildings and now their fire safety have been paid more attention. Thence, a new material, magnesium hydroxide (Mg(OH)2) was introduced and its possible application was discussed in this paper in order to protect constructions better. It was analyzed at three aspects including its advantages, physical and chemical properties and fire suppression effectiveness. Mg(OH)2 powder is better because it is cleaner, more efficient and lower cost of production, store and transportation. A comparison of physical and chemical properties between magnesium compounds and other common commercial fire suppressant proved that Mg(OH)2 powder absorbed more heat when they decomposed. In a bench-test, the Mg(OH)2 powder is also more efficient than the common commercial BC powder and ABC Powder. The results have proved that Mg(OH)2 powder is a kind of good, clean and high efficient powder to suppress tall building fires.
