dust suppression eliminates dust clouds

Many bulk material handlers think of combustible dust as a housekeeping item. Once enough of it gathers in one place, they’ll assign personnel to clean it up.

What they might often overlook are the combustible dust hazards. The Occupational Safety and Health Administration (OSHA) defines combustible dusts as “fine particles that present an explosion hazard when suspended in air in certain conditions.” They have great potential to cause or contribute to a fire, a flash fire or an explosion. Plant staff also can inhale them and develop long-term health problems. Combustible dusts can interfere with maintenance of process equipment as well.

Some plant operators might say, “It’s never happened here before,” or “It will never happen here.” They may not realize they’ve been getting by on luck. But when that luck runs out – and often it will – it affects both people and property, and the business takes a hit.

It’s always better to know and be proactive about the hazards of combustible dust. Industries such as coal, biomass, wood pellets, cement, paper, rubber, wood-product processing and agricultural have combustible dust hazards. If left alone, small amounts of build-up can develop into a big and menacing problem. Effective and thorough dust management reduces personal and material risks and reinforces a more productive and profitable business.

NFPA 652 and DHA

Both plant management and maintenance personnel should review National Fire Protection Association (NFPA) 652: Standard on the Fundamentals of Combustible Dust, which outlines proactive practices for preventing and decreasing combustible dust hazards. The standard provides important dust management criteria for building design, life safety, fire protection, dust containment, dust collection, wet dust extraction, conveying, handling and controlling ignition.

Another vital step in effective dust management is performing a Dust Hazards Analysis (DHA), a systematic review of dust hazards and how they are being lessened and managed. The DHA will be a required safety practice as of September 7, 2020.
