The of Dangersa Dust Health Hazards Associated with Dust Eye Irritation Nasal Dryness Headaches Eczema Ocupational Asthma Combustible dust is defined by NFPA 654 as: "Any finely divided solid material that is 420 microns or smaller in diameter and presents a fire or explosion hazard when dispersed and ignited in air." 5 to 10 44 to 74 MICRONS • Talcum powder • Fine silt • Red blood cells • Cocoa MICRONS • Pollen • Milled flour • Course silt 297 to 1000 MICRONS • Course Sand 105 to 149 MICRONS • Table salt Typical Combustible Dusts Natural Materials Synthetic Materials Inorganic Materials Wood Dye Stuffs Plastics Sulfur Sugar Paper Iron Нехamine Magnesium Starch Carbon Compounds Aluminum Flour Titanium 22 Ti Titanium Dust explosions in American factories are more common than you think. 350 . 133 . MORE HUNDREDS EXPLOSIONS Since 1980 PEOPLE Killed Injured Dust also affects quality control because it collects in motors and electrical cabinets that aren't airtight. K Values for Different Types of Dust Any combustible dust with a K value greater than zero can be subject to dust deflagration. Even weak explosions can cause significant damage, injury and death.
