Particulate matter, suspended particulate matter, atmospheric dust, particulate matter, total suspended particulate (TSP), are terms that commonly identify the group of substances suspended in the air (fibers, carbon particles, metals, silica, polluting liquid or solid). Particulate matter is the pollutant that is now considered the greatest impact in urban areas, and is composed of all those solid and liquid particles dispersed in the atmosphere, with a diameter ranging from a few nanometers to 500 microns and above (ie billionths of a meter to half a millimeter).

The consequences of an industrial dust explosion or fire are unthinkable - worker injury, loss of life, property damage, business interruption, and irreversible environmental harm. Few companies realize how many diverse and common industrial applications produce combustible particulates, or where in their facilities this catastrophic threat is settling. What is a combustible dust? “A combustible particulate solid that presents a fire or deflagration hazard when suspended in air or other oxidizing medium over a range of concentrations, regardless of particle size or shape” – NFPA 654? High Risk Applications Metalwork (aluminum, magnesium, or titanium and others) – cutting, grinding, or finishing Ceramics – raw product handling and enamel spray Chemicals – material handling, crushing, grinding, roasters, kilns, and coolers Coal mining – material handling, de-dusting, drying, air cleaning Food (flour, sugar, and others) – mixing, grinding, blending, bagging, and packaging Foundry – sand handling, tumbling mills, abrasive cleaning, and shakeout Pharmaceutical – mixing, grinding, blending, bagging, and packaging Rubber – mixing, grinding, talc dusting, de-dusting, and batch-out rolls Woodwork – woodworking machines, sanding, waste conveying?
