Combustible dust is finely separated or divided dust that poses a fire or explosion hazard when suspended in air in the right concentrations. Even some materials that would not normally burn can burn in dust form. The particles must be small enough to float in the air, and the material...

Workers in construction are at risk for exposure to crystalline silica, a common mineral found in construction materials like concrete, brick, mortar, sand, and stone. If you have ever seen a sidewalk being jackhammered, and concrete dust blowing in the air, you have probably seen respirable crystalline silica. When workers...

When combustible or non-combustible materials are broken down into fine dusts or powders, they create a fire and explosion hazard affecting many operations and materials: sugar, flour, animal feed, plastics, paper, wood, rubber, furniture, textiles, pesticides, pharmaceuticals, paints and resins, dyes, coal, and metals. Safeguards need to be activated to...
Combustible dust is any “finely divided solid material that is 420 microns or smaller in diameter and presents a fire or explosions hazard when dispersed and ignited in air.” Materials such as sugar, flour, animal feed, plastics, paper, wood, rubber, furniture, textiles, pesticides, pharmaceuticals, paints and resins, dyes, coal, and...
Inhalation of cement dust may occur when workers empty bags of dry cement material to make concrete, cut concrete work tiles, and use jackhammers to break up a sidewalk or road during repairs. This exposure can cause nose and throat irritation. Long- term exposure to concrete dust containing crystalline silica...
Concrete is easy to work with, versatile, durable, and economical. By taking a few basic precautions, it is also one of the safest building materials known. Relatively few people involved in mixing, handling, and finishing concrete have experienced injury. Nonetheless, concrete work is usually hard physical labor that presents many...
There has been much discussion about silica dust in the past few years. OSHA has issued a regulation to help protect workers from overexposure to this dust. It has been largely unregulated in the past and because of this, many workers have been faced with overexposure. The CDC reports that...
Silica exposure remains a serious threat to nearly 2 million U.S. workers, including more than 100,000 workers in high risk jobs such as abrasive blasting, foundry work, stonecutting, rock drilling, quarry work, and tunneling. The seriousness of the health hazards associated with silica exposure is demonstrated by the fatalities and...
