Fact Sheet: 2011 Combustible Dust Related Incidents, NFIRS Analysis


Fact Sheet: 2011 Combustible Dust Related Incidents, NFIRS Analysis from Combustible Dust Policy Institute



A Combustible Dust Policy Institute (CDPI) preliminary analysis of 2011 National Fire Incident Reporting System (NFIRS) incident data provided by the National Fire Data Center of the U.S. Fire Administration indicated over 500 combustible dust related incidents in manufacturing facilities where dust was the item first ignited. Near misses include incidents that did not result in any harm to personnel, the facility, process, or product. Analysis did not include the grain sector or coal-fired energy plants.

Additionally, the CDPI analysis does not include many incidents that were not reported by fire departments to the National Fire Data Center. As a result there are many more combustible dust related incidents that cannot be evaluated in determining whether the incident was a near miss or not. 

Special thanks to the nation's Fire Departments, NFIC State Program Managers, and the National Fire Data Center at the U.S. Fire Administration in sharing this valuable Information.  

Casual Pathways Between Near Misses and Catastrophic Events 
Excellent article by Carsten Busch from Norway, highlighting Common Cause Hypothesis (CCH) which also pertains to near misses and catastrophic combustible dust related incidents. In the current OSHA ComDust rulemaking process and recently reintroduced proposed combustible dust bill H.R. 691, incidents resulting in property/content loss (30% NFIRS analysis) yet no casualties (approximately 95%) are considered near misses. Yet the casual pathways (ignition sources, dust management strategies, etc.) for the consequences of all combustible dust related incidents are all the same. 

The true definition of a "near miss" is an incident not resulting in any harm to personnel, the facility, process, or product. So why are near misses ignored in accounting for combustible dust related fire and explosion hazards in protection of the workplace in the OSHA ComDust rulemaking process and recently reintroduced proposed combustible dust bill H.R. 691?

Report on preliminary findings of a study of incident reporting systems for near misses in non­medical domains. This can also apply to combustible dust related incidents/accidents where NFIRS data provides a multitude of information in developing barriers for the prevention of future accidents.

Near Misses in Non­-medical Domains
"Consequently, the same patterns of causes of failure and their relations precede both adverse events and near misses." Sounds familiar with ComDust related incidents at facilities whether it was flash fire, dust explosion, or layer fire? They all have casual pathways of improperly managed ignition sources and fuel sources. A written fire prevention plan (FPP) addresses these casual pathways initially at the organizational level. The next step would be implementation at the technical and operational level.

"We defined a near miss as any event that could have had adverse consequences but did not and was indistinguishable from fully fledged adverse events in all but outcome." Note: National Fire Incident Reporting System (NFIRS) was not included in the report of near misses in non­medical domains. 

U.S. Chemical Safety Board (CSB): Near Misses.
Dust Explosion Hazard Awareness / Imperial Sugar Management and Workers
(Page 54 .pdf) "The CSB concluded that the small events and “near-misses” caused company management, and the managers and workers at both the Port Wentworth, Georgia, and Gramercy, Louisiana, facilities to lose sight of the ongoing and significant hazards posed by accumulated sugar dust in the packing buildings."

CSB Key Findings: Imperial Sugar Refinery
Page 48 .pdf)  # 4 "Company management and the managers and workers at both the Port Wentworth, Georgia, and Gramercy, Louisiana, refineries did not recognize the significant hazard posed by sugar dust, despite the continuing history of “near-misses’”

Hoeganaes
(Page 14 ,pdf) "Operators and mechanics reported being involved in multiple flash fires during their employment at the Gallatin facility. At the time of the incidents, many were aware that the iron dust could burn or smolder. However, they were not trained to understand the potentially severe hazard when accumulated dust is dispersed in air. Rarely would operators report the minor flash fires and “near-misses” that periodically occurred."

(page 27 .pdf) CSB Recommendations to Hoeganaes 2011-4-I-TN-R9
"Develop and implement a “near-miss” reporting and investigation policy that includes the following at a minimum:"
• Ensure facility-wide worker participation in reporting all near-miss events and operational disruptions (such as significant iron powder accumulations, smoldering fires, or unsafe conditions or practices) that could result in worker injury.

• Ensure that the near-miss reporting program requires prompt investigations, as appropriate, and that results are promptly circulated throughout the Hoeganaes Corp.

• Establish roles and responsibilities for the management, execution, and resolution of all recommendations from near-miss investigations

• Ensure the near-miss program is operational at all times (e.g. nights, weekends, holiday shifts).  

Conclusion 
Near misses can no longer be ignored. It's very distressing that OSHA in the combustible dust rulemaking process in conjunction with the legislators in the reintroduction of the proposed combustible dust bill H.R. 691 have chosen to ignore 95% of combustible dust related incidents in manufacturing facilities, which do not result in personnel casualties. Yet these very same incidents, as history illustrates are precursors to catastrophe.

The Combustible Dust Policy Institute (CDPI) researched over 500 combustible dust related fires and explosions in manufacturing facilities utilizing 2011 National Fire Incident Reporting System (NFIRS) data provided by the U.S. Fire Administration's National Fire Data Center. All 50 states report NFIRS data with approximately 23,000 fire departments out of over 30,000 fire departments in the USA reporting NFIRS data each year which consists of about 75 percent of all fires occurring annually.

2011 NFIRS data  indicated combustible dust related fires and explosions occurring in 40 out of 50 states with nine states reporting over twenty incidents as indicated by the table above. Since NFIRS is a voluntary program not all fire departments in the USA report incidents where property damage occurred. Content loss is also noted in NFIRS data in addition to property loss.

"NFIRS distinguishes between “content” and “property” loss. Content loss includes loss to the contents of a structure due to damage by fire, smoke, water, and overhaul. Property loss includes losses to the structure itself or to the property itself. Total loss is the sum of the content loss and the property loss."

In the vast majority of over 500 incidents in 2011 no fatalities, injuries, nor property damage occurred, which is similar to the results of a confined structure fires defined by the U.S. Fire Administration. In contrast, two workplace fatalities and fourteen injuries occurred in nine states. Additionally, ten fire-fighters sustained injuries while responding to combustible dust related fires. The 2011 NFIRS injury and fatality data conflicts with the 2006 CSB Combustible Dust Hazard Study for the 1980-2005 time frame, where it was noted, "injuries and fatalities occurred in 71 percent of the incidents." In 2011, property damage occurred in 30 percent of incidents with damage of less than $5,000 in 56 percent of  incidents.

Combustible dust related incidents occurred in 20 of the 21 manufacturing subsectors in 2011. The food and chemical manufacturing subsectors experienced a total of nine incidents ( two food, seven chemical). In a following post additional information will be provided on a profile of affected industries and types of combustible dust involved in combustible dust related incidents during 2011.

Special thanks to the dedication and hard work of the local fire departments, state program managers, and staff at the National Fire Data Center at the U.S. Fire Administration in providing NFIRS data to end-users, "Fighting Fire with Facts." Without their continued efforts in identifying combustible dust related incidents, sharing this valuable information would not be possible.

2011 Over 500 Combustible Dust Related Incidents in Manufacturing Sector

NFIRS Structure



National Fire Incident Reporting System (NFIRS) analysis #94 item first ignited and #700 manufacturing property use. NFIRS is a voluntary reporting system so many fire incidents are not reported to the National Fire Data Center of the U.S. Fire Administration in Maryland. If there is no incident report for the legal record, then it's as if the incident never happened. Thanks to the dedication of the local fire departments, state program managers of the the National Fire Information Council (NFIC), and the National Fire Data Center in providing this valuable incident data to stakeholders for further analysis and evaluation.

NFIRS analysis of 2011 manufacturing sector workplace combustible dust related incidents indicated 14 injuries and 2 fatalities. For all items first ignited at manufacturing facilities including dust, NFIRS data indicated a total of 115 workplace injuries and 15 fatalities. In addition to workplace injuries 10 firefighters sustained injuries responding to combustible dust related incidents at manufacturing properties in 2011.

Currently about 23,000 fire departments report NFIRS data to the National Fire Data Center each year out of approximately 30,145 fire departments. (Source: U.S. Fire Administration and NFPA). As a result solely utilizing NFIRS data is not conclusive and does not provide a total count of incidents, injuries, fatalities, and property damage. In contrast, NFPA conducts a National Survey of fire departments in the development of a scaling ratio in conjunction with NFIRS data which assists in filling the gaps of insufficient NFIRS data.

Stakeholders are highly encouraged to review the informative NFPA report "Fires in U.S. Industrial and Manufacturing Facilities (2006-2010) " provided by NFPA’s Fire Analysis and Research Division. For all types of fires the recent NFPA 2012 report noted an annual average of 22 fatalities and 300 injuries at industrial and manufacturing properties which also includes the utility, defense, agriculture, and mining sectors..

Evaluating NFIRS data stakeholders can observe emerging trends in NAICS, Area of Fire Origin, Heat Source, Type of Material First Ignited, Cause of Ignition, Factors Contributing to Ignition, Equipment Involved in Ignition (EII), Presence of Detectors, Presence of Automatic Extinguishing System, Casualties, Property Loss, etc. The next intermediate step in an evaluation is utilizing NFPA 550 Guide to the Fire Safety Concepts Tree then culminating with implementing control measures in the NFPA combustible dust standards, International Fire Code, and FM Global Property Loss Prevention Data Sheets.

The OSHA Combustible Dust; Advance notice of proposed rulemaking, Table 1--Industries Having at Least One Recorded Combustible Dust Incident Reported Since 1980  is misleading and not reality noting 422 combustible dust incidents in a 28 year time span or approximate average of 15 incidents annually. To fully understand the depth of the combustible dust problem in the workplace it is imperative the fire service be included in future dialogue regarding training, outreach, education, inspections, and enforcement.

Key stakeholders from the fire service having intimate knowledge of fire and explosion hazards in non-residential building structures include: International Association of Firefighters (IAFF), International Association of Fire Chiefs (IAFC), National Volunteer Fire Council (NVFC), National Association of State Fire Marshals (NASFM), and National Fire Information Council (NFIC).

 
Appropriately the contentious issue of combustible dust hazards in the workplace is primarily a fire hazard and secondarily an explosion hazard. Subsequently, the majority of combustible dust related incidents are non-consequential (near misses) fires with no injuries, fatalities, nor property damage. This results in a disturbing mindset of "normalization of deviation" where facility owners and managers falsely believe that since nothing bad has happened in the past then nothing bad will happen in the future. Initially addressing the fire hazards will eliminate the possibility of secondary catastrophic dust explosions or disastrous flash fires.

Decade anniversary: Silo fire at Tire Recycling plant

NCNewsPress.com Article Feb 6, 2012
U.S. Fire Administration/Technical Report Series: Tire Recycling Facility Fire Nebraska City, Nebraska USFA-TR-145/January-February 2002

Excerpts from US Fire Administration report:

The Facility
The plant had been inspected by Nebraska State Fire Marshal’s Office on more than one occasion and had a history of poor housekeeping as well as a track record of poor equipment maintenance. There had previously been two fires at the site, as well as two fires at another EnTire facility, also located in Nebraska City.

The Incident
The explosion expelled chunks of rubber that were approximately two to four inches in diameter. Debris was hurled 300 to 400 feet away, damaging and destroying apparatus and equipment as well as injuring the thirteen firefighters

Investigation
The State Fire Marshal has determined that the probable cause was a faulty bearing in the stiff leg auger which carried the crumb rubber from the ground level to the top of the silos.

The bearing overheated igniting the rubber debris around the sugar base. A contributing factor was the poor housekeeping practices. No definite cause of the explosion has been identified,

Lessons Learned
Most local zoning and building codes do not adequately address facilities of this type.
Traditionally, volunteer fire departments do not become involved in local zoning issues and often lack the resources to properly preplan target hazards.

The facility in this incident was not designed for its use, nor were there adequate safe guards built into the process since the com­plex already existed and was modified to accommodate this particular process.

Fire departments should become more proactive in the permitting and zoning process and should endeavor to ensure appropriate code enforcements in facilities of this type, whenever it is possible to do so.
