Michigan Combustible Dust Fires Reoccurring


View Larger Map

How can there be two combustible dust fires in succession within one week like has recently occurred in Muskegon, Michigan at the metal finishing facility of Port City Industrial Finishing Inc? In last Tuesday’s incident the dust collector/silo sustained $120,000 of fire damage and yesterday courageous and heroic fast-acting employees emptied all 18 fire extinguishers in quenching another combustible dust fire in the vicinity of a dust collector/air handling unit inside the building.

Michigan Scorecard

Michigan is high on the national scorecard of a continual succession of preventable and predictable combustible dust explosions and fires. Of a 7.0 earthquake magnitude on the scale of the recent tragic Imperial Sugar Refinery explosion, the Ford Rouge plant in Dearborn, Michigan experienced a coal dust explosion nearly two decades ago on February 1, 1991, causing 6 fatalities and 30 injuries after the dust had settled.

Two short years would pass when on May 25, 2001 another fireball and combustible dust explosion would erupt in the state at a Georgia Pacific particle-board plant in Gaylord, Michigan. In this incident there were 15 injuries of which nearly half of them where from six firefighters who were extinguishing hot spots from the earlier fire when another combustible dust explosion erupted.

2001 Not a Good Year

Four months later on September 21, 2001 as investigators were still analyzing and writing their accidents reports on the Georgia-Pacific explosion another combustible dust explosion occurred at a Wayland, Michigan milk processing plant, which resulted in two injuries and minor damage to the facility.

2001 was not a good year for the nation or Michigan either concerning explosions that seemed to come out from nowhere. The New Year in 2002 fared no better and even before the dismal anniversary of the catastrophic coal dust explosion at the Ford Rouge Plant had turned its pages on the calendar another coal dust explosion raised its nasty head on January 16, 2002 on the banks of Lake Superior in Marquette, Michigan.

At an electric services plant, a coal-fired boiler was being brought on-line where the coal feeding system had not been purged properly and an excessive amount of coal dust left in the system ignited, causing an explosion and leaving a fatality in its wake. The dragon had spoken and was not to be ignored.

National Problem

The last six years have been dormant in comparison to earthquakes’ with several combustible dust fires spread out through 2003 and 2004 with no fatalities or injuries,
synoymonous to tremors and warning signs. It’s now when a facility such as Port City Industrial Finishing, where two combustible fires occur in succession within a week that notice occurs. In retrospect, Michigan only had nine combustible dust incidents from 1989-2004 leaving 7 fatalities and 59 injuries.

Michigan is not being singled out in the scheme that the dragon has planned out. Since he lashed his ugly tail upon the serene western bank of the Savannah River at the Dixie Crystal sugar refinery in Port Wentworth, Georgia over two dozen combustible dust explosions and fires have occurred throughout the nation.

So how many more fatalities and injuries must occur before the issue is addressed and a mandatory OSHA comprehensive combustible dust standard is implemented utilizing National Fire Protection Association combustible dust codes?

Quaker Oats Blows It's Top

http://www.gazetteonline.com/apps/pbcs.dll/article?AID=/20080324/NEWS/233198211/1006/news

Around sunrise as hearty Iowans were beginning their workday with the freezing and brisk morning commute in downtown Cedar Rapids, Iowa a dust explosion rocked the eight floor of the prominent Quaker Oats facility, which has been a landmark on the east bank on the Cedar River for over a century.

Luckily no injuries occurred and it only brought back a brief stark reminder of a catastrophic dust explosion that occurred in Cedar Rapids, nearly a century ago on May 19, 1919 at the Douglas Starch Works, where a dust explosion leveled the building causing 48 fatalities. Prior to 1899 George Douglas was a partner with the principles of North Star Milling, the predecessor of Quaker Oats founded in 1873.

Smiley Face

The familiar friendly face on that red, white, and blue Quaker Oats box in our cupboard has a rich history and there is nothing happier in the morning than crunching on a bowl of Cap”n Crunch (Quaker Oats product) to get the day started. The risks involved in getting the thousands of happy faces started in the morning are another story.

Handling food products in the manufacturing process produces inherent dangers with the seemingly harmless combustible dusts that are generated in the workplace. So who would have thought something as harmless as sugar, like earlier last month at Imperial Sugar in Georgia, would have the explosive power of another 9/11?

City-State Not Immune

Iowa has not been immune to these dangers as there have been over a dozen dust explosions over the last twenty years in the state according to the 2006 Chemical Safety Board’s Combustible Dust Hazard Investigation. Since 1991, in Cedar Rapids, there have been six dust explosions at wet corn milling, starch, bakery mix, cereal, and animal by-product plants. Luckily, no injuries just a lot of broken glass and rattled nerves and time to think more about prevention in the future.

Cause’s and ignition sources range from fires, spontaneous combustion, sparks, hot metal, and unknown. Over half of dust explosions never end up in a determination of causes due to the destruction that is wracked on the facility. Yet static electricity would be a good place to start. Are the workers wearing anti-static clothing in addition to anti-static floor covering as found in many hospitals in preventing potential explosions?

Voluntary OSHA Compliance

Voluntary measures of anti-static clothing only go so far in prevention as it is not required at facilities that generate combustible dusts. Additionally the operating costs for companies would be exorbitant in the investment of anti-static flooring coverings, which would fiercely eat into quarterly earnings statements.

This is only the tip of the iceberg when it comes to voluntary standards that the National Fire Protection Association lists in their numerous fire codes in handling metal, food, plastics, rubber, coal, wood, and other combustible particulate solids that generate combustible dusts. For instance, there are many more issues in contrast to explosion prevention which leads to explosion mitigation and covers ventilation, isolation, and suppression of dust explosions in milliseconds.

Myth or Dream

That’s where the real big bucks enter into the picture. Think of it as an entire industry rising from the ashes like the mythological Phoenix where a cottage industry of explosion protection devices is installed at all facilities generating combustible dusts and the idea of a future dust explosion would be decreased immensely. But that is only a dream such as a myth.

Threat From Within

Since the Homeland Security Act was passed in 2002, billions of dollars have been spent by government and industry in providing protection from outside threats. But what about protection from inside the nation where worker fatalities, injuries, and devastating economic impact occurs on a regular basis?

A major concern is that the Occupational Health and Safety Act was passed nearly four decades ago and it has yet to live up to the lofty goals of aggressively attacking the continual occurrence of fatalities and injuries in the workplace. Instead there is a patchwork of voluntary compliance and alliances with industry.

Labor or Industry

This mode of operation was reinforced during the March 12, 2008 hearing at the House Committee of Education and Labor on the HR 5522 "The Combustible Dust Fire and Explosion Prevention Act of 2008.” Where industry and business through the voice of the powerful and omnipresent U.S, Chamber of Commerce, the world's largest not-for-profit business federation, representing 3,000,000 businesses reiterated their position that a OSHA comprehensive dust standard is not a viable action.

Until an OSHA comprehensive combustible dust standard in the protection of workers and the workplace is instituted more preventable and predictable dust explosions and fires will occur. Since the catastrophic explosion at Imperial Sugar six weeks ago resulting in 13 fatalities there has been nearly two dozen additional combustible dust incidents. Maybe the dust explosion at Quaker Oats will be wake up call for immediate action as the kindred spirits Douglas Starch Works and Imperial Sugar look on.

Timeline: Recent Combustible Dust Explosions


Click on the Picture for a Better View

The most recent combustible dust explosion occurred on the same day that the House Education and Labor Committee was having a hearing on HR 5522, "The Combustible Dust Fire and Explosion Prevention Act of 2008".

Testifying were William Wright, Acting Chair of the Chemical Safety Board: Ed Foulke, OSHA; Tammy Miser (whose brother, Shawn Boone, was killed in a combustible dust explosion); David Sarvadi, representing the US Chamber of Commerce; and Amy Spencer of the National Fire Protection Association.

Up Close Imperial Sugar Explosion Update

Six weeks have passed now since the horrific Imperial Sugar Refinery combustible dust explosion that occurred in Port Wentworth, Georgia on the evening of February 7. Imperial Sugar CEO John Sheptor allowed reporters an up close view of the blast site while investigators took a break during the Easter weekend.

Today News Threes Alice Massimi and photojournalist Art Ottimo were able to get a close-up look at the destruction caused by this horrific incident.
Combustible dust explosions and fires are a regular occurrence at numerous manufacturing and processing facilities across the United States and the Imperial Sugar incident is not an isolated case. Already 20 combustible dust related fires and explosion have occurred since the explosion in Port Wentworth.
3/18/08 MUSKEGON COUNTY Muskegon firefighters responded at 1:52 a.m. to the plant at 1867 Huizenga, where they discovered the plant's "dust collector" had caught fire, said Fire Marshall Major Metcalf. It's unclear why the device -- located outside the plant -- malfunctioned

Combustible dust fires originating in dust collectors occur with regularity and without proper voluntary detection, isolation, ventilation, and suppression measures in conjunction with the regulatory good housekeeping requirements additional incidents, will continue.

Just abiding by current combustible dust industry standards and OSHA regulations is not enough as Imperial Sugar CEO John Sheptor suggests, with all good intentions

PORT WENTWORTH, GA (WTOC) 3/21/08 - "We will rebuild this facility to the best knowledge we have with regard to the management of combustible dust, whether that be a regulation or industrial standard and by all means we believe we were operating according to these codes and standards previously," he said.

Rebuilding the sugar plant in compliance to current OSHA combustibles dust regulations will only prolong the situation of the continual occurrence of more combustible dust explosions.Especially since abiding to National Fire Protection Association (NFPA)codes on combustible dust is only voluntary.

At a recent congressional hearing of the House Committee of Education and Labor concerning the introduction of the Combustible Dust Explosion and Fire Prevention Act (H.R. 5522), David Sarvadi a lobbyist and attorney representing United States Chamber of Commerce the world's nationwide largest not-for-profit business federation, of 3,000,000 businesses, didn't believe that a mandatory OSHA combustible dust standard, which includes NFPA combustible dust explosion preventative and mitigative measures was a good idea.

Meanwhile combustible dust explosions are still occuring

3/13/08 By TOM QUIGLEY The Express-Times HIGH BRIDGE,NJ Fire erupted Wednesday inside an enclosed dust collector in a metal-grinding room at the Custom Alloy plant on Washington Avenue, borough Fire Chief Jeffrey Smith said.

The severity of the situation is not just solely on the protection of workers in the workplace from the unknown dangers of seemingly harmless combustible particulate solids and the combustible dusts that are generated. But now our nation's firefighters are at risk when fighting a structure fires where unrecognized combustible dusts are generated and primary and secondary dust explosions can occur during the deflagration event.

And so the saga continues:

3/10/08 WCCO.com OAK PARK HEIGHTS, Minn. (AP) ― Xcel Energy is shutting down its King plant in Oak Park Heights after a fire and possible explosion in a building near the coal-fired plant.
This was the second combustible dust explosion of coal dust within three months at the same facility. Currently, Minnesota is under a voluntary state OSHA program and doesn't even have an emphasis program regarding combustible dusts. So how is it that future preventable and predictable combustible dust explosions and fires can be diminished if there is no nationwide mandatory protective standards?

Spooner Explosion-Dust or Vapor?



The catastrophic Tuesday chemical plant explosion at the Cortec aerosol can filling facility in Spooner, Wisconsin is still a mystery to local, state, and federal investigators. Luckily, most of the workers were in the break room when the mysterious explosion destroyed the facility. Yet two injuries occurred with the burn victims still in the hospital.

Cortec is a global leader in corrosion protection technology with its proprietary vapor-phase corrosion inhibitors. VCIs are environmentally friendly organic chemicals that condense on metal surfaces, creating an invisible barrier to moisture. Products that are filled in aerosol cans include rust removers, rust preventers, biodegradable cleaners, and degreasers.

With hundreds of diverse corrosion protection products manufactured at their other facilities, Cortec provides corrosion protection products for over 70 countries in conjunction 500 local distributors. For instance, NASA uses the products’ on the space shuttle and the U.S. military has a multitude of uses for the products in the adverse conditions which it operates whether land, sea, or air.

Normally aerosol can filling can be a potentially dangerous operation in the manufacturing process. Yet Cortec has alleviated that hazardous aspect with its EcoAir aerosol can product which utilizes unique technology in the form of aerosol products that are powered by compressed air which is not flammable. So how did the facility explode if it doesn’t use liquefied petroleum gas (LPG), dimethyl ether (DME), difluoroethane (DFE), or butane as a aerosol propellant?

That’s the mystery. Additionally, newspapers have stated through witness accounts, that no one can recall smelling any vapor such as a flammable gas leak. Furthermore, a business owner across the street heard a primary explosion then a larger secondary explosion followed by the huge fire.

Is it possible that the vapor corrosion inhibitor (VCI) in a dust form, prior to filling the aerosol cans, had accumulated over a period of time on overhead surfaces and ledges unbeknownst to plant management and the workers? That’s the big question even with the aisles and passageways spotless through conscientious housekeeping yet a hidden danger could be lurking above.

Metal Combustible Dust Fires Rage On

Combustible dust fires across the nation have been an ongoing trend over the past six weeks since the catastrophic Dixie Crystal Sugar Refinery explosion last month.

"MUSKEGON COUNTY — A fire that started early this morning at the Port City Industrial Finishing Inc. plant in Muskegon caused about $120,000 in damage, fire officials estimate."

In this incident lady luck held the high cards with no injuries nor fatalities at a facility that polished aluminum used for Harley-Davidson parts.

The last combustible dust incident occurred a week earlier at Custom Alloy Corporation in High Bridge, New Jersy when a fire ensued inside an enclosed dust collector in a metal-grinding room.

"Firefighters wearing protective breathing gear had to take apart the collector to extinguish burning metal particles inside. Smith said a small dust explosion occurred during the fire."
In that incident the small dust explosion occurred while fire teams were fighting the fire. Luckily, Fire Chief Jeffrey Smith's team of over 70 firefighters from the boroughs of Quakertown, Lebanon, Lebanon Township, Califon, Glen Gardner, Hampton, and High Bridge Rescue walked away unscathed.

The hazards of combustible particulate solids (CPS) and the combustible dusts that are generated in manufacturing processes can become deadly with the explosive power of gunpowder when suspended and in a confined space of the shop floor and exposed to an ignition source such as static electricity at the seemingly harmless millijoule level.

Tens of thousands of workers across the nation will arrive at work tomorrow morning with no idea of the dangers they are exposed to when handling metal, food, feed, grain, textile, paper, and other harmless bulk materials (combustible particulate solids) prior to initiating the manufacturing process. It's only when the materials in their raw form begin to be processed (combustible dust) that the dangers set in.

Thats when the dust begins to accumulate on the shop floor, ledges, hard to reach spots, and eventually suspension in the air. All that is missing for a combustible dust incident is ignition. In the right conditions with a worker walking across the shop floor, 10 millijoules of charge can be generated and touching the right spot 1000-2000 picofarads can jump across an ungrounded surface and hopefully lady luck is nearby.

Either way in some form or other, across all industries spread throughout the nation, approximately 15 of those workers will never make it to the time clock and eventually home alive to see there loved ones, lady luck won't be kind to them.
