We have also seen the effects of "static cling," when our clothes cling together in the dryer. Static electricity, as a source of ignition for flammable vapors, gases, and dusts, is a hazard common to a wide variety of industries. A static spark can occur when an electrical charge accumulates on the surfaces of two materials that have been brought together and then separated (between two solids, between a solid and a liquid,...

Dust Explosions Dust Explosions - When combustible or non-combustible materials are broken down into fine dust 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. To prevent fires from dust explosions, control the “dust explosion pentagon.” This includes the traditional fire triangle: fuel, heat, and oxygen along with a dust cloud and enclosed space. Keep dust levels (fuel) in the workplace to a minimum with dust control and housekeeping. Control flame and ignition sources (heat) such as pilot...
