Dust in the chemical processing industries (CPI) is present in numerous operations, including powder processing; the transport of materials on belt or rotary-screw conveyors; grinding materials in giant shredders and pulverizers; machining, sawing, grinding or sanding operations; dumping bags of materials into reactors; handling coating materials; as well as the processing of pharmaceuticals and foods. An...

January 1, 2014
Dust is a critical consideration in the chemical process industries (CPI) from both a process safety standpoint — as a potential fire and explosion hazard — and from an occupational safety standpoint — as a potential worker exposure hazard. Reinforcing basic concepts about dust behavior and properties can help reduce the risks. Health hazards Airborne particles are solids suspended in the...

The U.S. Occupational Safety and Health Admin. (OSHA; Washington, D.C.; www.osha.gov) has flagged combustible dusts as one of its top issues since the Imperial Sugar Mill explosion in Port Wentworth, Georgia, that killed 14 employees and injured many others in February 2008. Combustible dust is, in fact, one of OSHA’s National Emphasis Programs (NEPs).   The situation today Despite the...

Leading up to this month’s 2012 U.S. Presidential election, the legislative landscape has been relatively uneventful. On top of their preoccupation with the election campaigns, lawmakers on both sides of the political spectrum have been reluctant to pin their agendas to any bill that might significantly alienate large groups of voters. Nevertheless, two relatively significant changes are coming down...

Preventing dust explosions is not rocket science, and still these disasters occur. This article is written to help prevent these accidents. It describes how and why these explosions happen and what can be done to avoid them.   Why they occur Dust explosions occur when three conditions are present simultaneously. The first is that there is a dust cloud of a combustible material (the fuel). The second...

An explosion is defined as “a rapid increase in volume and release of energy in an extreme manner,” and is usually accompanied by high temperature generation and gas release. Flammable gases, vapors, dusts and ambient oxygen — all present in chemical processing facilities — can react to cause an explosion that essentially creates a shock wave. As a result of modern production...

One of the biggest issues related to dust collection is compliance with U.S. Occupational Safety Health Administration (OSHA) and U.S. Environmental Protection Agency (EPA) regulations regarding combustible dusts and air quality. And as both agencies up the ante with tighter regulations and more scrutinizing inspections, it is imperative that processors make sure their facilities are meeting the standards...

The U.S. Chemical Safety Board (CSB; www.csb.gov) has  released test results confirming preliminary conclusions that two flash fires, which occurred at the Hoeganaes Corp. plant in Gallatin, Tenn., involved the combustion of iron powder that had accumulated throughout the facility and became airborne in combustible concentrations. A flash fire on January 31 killed one worker and seriously burned...

Following the devastating explosion at the Imperial Sugar Co.’s Georgia factory that killed 14 people, injured many more employees and leveled the facility in February 2008, it was determined by the U.S. Occupational Safety and Health Admin. (OSHA; www.osha.gov) officials and the U.S. Chemical Safety Board (CSB; both Washington, D.C.; www.csb.gov) that the catastrophe could have been prevented had...

The U.S. Occupational Safety and Health Administration (OSHA) is seeking input on the approach to use in developing its federal standard for combustible dust. In its Advance Notice of Proposed Rulemaking (ANPR) on Combustible Dust, OSHA identified five National Fire Protection Association (NFPA) combustible dust standards that address the hazards of combustible dust processes. Of the five NFPA...

Household items, such as breakfast cereal, flour, corn starch and sugar are so common that many were left surprised after the 2008 combustible-dust explosion at a sugar refinery in Georgia. Heard in much of the early media coverage was the question “How could sugar explode?” Plant explosions are, thankfully, not routine occurrences. However, when they do occur, it is the unusual event —...

In a final draft report released today, U.S. Chemical Safety Board (CSB; www.csb.gov) investigators said the February 7, 2008, explosion at the Imperial Sugar refinery in Port Wentworth, Ga., resulted from ongoing releases of sugar from inadequately designed and maintained dust-collection equipment, conveyors, and sugar-handling equipment. Inadequate housekeeping practices allowed highly combustible...

Better control of baghouses and cartridge-type dust collectors can pay dividends in energy savings, longer filter life and effort spent in tracking environmental compliance. That’s the message from Richard Kapcha, a control specialist with MikroPul (Charlotte, N.C.), which manufactures a wide range of dust collection equipment. “Until the early 1990s we were supplying baghouses with cleaning...

    Chemicals, plastics, pharmaceutical, food, agricultural chemicals, coal and bio-chemical industries have a wide array of processes where the raw materials, intermediates and products are in particulate form. Hazards associated with particulate solids are unique, and in most cases depend on the particle size. The purpose of this paper is to present a systematic framework for designing...
