B9MP D Powder

M28 powder is based on sodium chloride which has been treated with flow and moisture repellent additives. The extinguishing powder fuses to form a crust which excludes oxygen from the surface of the molten metal.

M28 will extinguish D Class (metal) fires, which includes most metals (Barium, Magnesium, Calcium, Sodium, Potassium, Titanium, Zirconium and Aluminium etc.). It is unsuitable for lithium fires.
