Fact Sheet: 2011 Combustible Dust Related Incidents USA Manufacturing Facilities

The Combustible Dust Policy Institute (CDPI) recently released a preliminary analysis of the 2011 National Fire Incident Reporting System (NFIRS) Data was 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. Many near misses included incidents that did not result in harm to personnel, the facility, process, or product. The analysis does not include the grain elevators or coal-fired energy plants.

     

The analysis stated over 500 combustible dust related incidents occurred in 2011.  The analysis mentions dust explosions at Imperial Sugar Company and the  Hoeganaes Corporation.  Both incidents were near misses that should have been addressed much sooner.  Action taken to resolve near misses can prevent catastrophic events from happening in the future.  Some previous ignition fires were not reported my maintenance crews and later resulted in dust explosions.

Article: 10 Ways A Dust Collection System Can Contribute To Your Plant’s Sustainability

A dust collector is designed to clean a factory of dust and fumes, thus making it fundamentally green.  By designing a dust collection system properly you can contribute to sustainability in many additional ways. An article appearing in Green Manufacturer magazine titled "10 Ways a dust collection system can contribute to your plant’s sustainability" written by air pollution control expert John Dauber, gives an easy overview in helping increase and maintain sustainability.

Make sure that the dust collector is compliant with the new U.S. Environmental Protection Agency (EPA) and National Emission Standards for Hazardous Air Pollutants (NESHAP) Rule 6x regarding weld fumes and other airborne contaminants.   You can request a written guarantee from the equipment manager stating the dust collector meets the standards.  Size the collector properly for the application and area.  An undersized dust collector can result in high pressure drop, frequent filter changes, high energy usage, and a host of larger maintenance issues.

If you are being accountable for a  high standard of sustainability shouldn't you require your dust collector supplier to do the same.  You can request a sustainability report or other documentation as evidence of its green manufacturing initiatives.   The use of a VFD variable-frequency drive controls fan speed effectively and efficiently.

Article: From Dust To Death - Six tips to stop dust collector explosions

Preventing combustible dust explosions has been an industry concern for years.   Increasing the stress for emergency health and safety managers trying to find the correct solution and maintain that solution for the future as well.  With so many standards, regulations, and codes one can get easily overwhelmed.  A recent article in ISHN Magazine by industry experts Tony Supine and Mike Walters condense the tedious task into a few informative tips.   

Reviewing the NFPA 654 standard will give you information on how to design a safe dust collection system.  It will also guide you to other NFPA standards regarding deflagration venting, explosion protection where venting is not possible, as well as standards for specific types of combustible dust and industries.   The NFPA has incorporated performance-based options, since 1995 using calculations in its standards for explosion protection equipment.   Since 2006 the NFPA has been allowing real world destructive test data to be used in place of the calculations data, as long as adequate testing has been proven.   Although often overlooked, real world data is permissible and your dust collection supplier may help you with cost savings and from over engineering,  all while not compromising safety.  

A hazard analysis is required to determine the level of fire and explosion protection required.  Testing the dust to determine the KST rating and Pmax by ASTM E 1226-10 standard needs to be established.  Quality is often overruled by a low price.   Is the value what it seems?  As documented a low-end dust collector will most likely need replacing after an explosion, where as a high quality gauge collector often only requires replacing only the explosion vent and filter cartridges.   High quality compliant equipment is reassurance and an investment in the future.   Keeping a clean facility is another key element in preventing dust explosions.  Hazardous levels of dust accumulation are the most common of all OSHA violations, often ending with fines.  The NFPA definition of hazardous surface dust is now 1/64 inch or 0.4mm in depth.   Staying alert of any changing conditions that can contribute to potential explosive problems should be normal practice.

Free Webinar to Explain EPA NESHAP Rule 6X

Camfil Farr Air Pollution Control (APC) will host a free educational webinar titled: “The New EPA National Emission Standard for Hazardous Air Pollutants (NESHAP), Rule 6X: Are You Compliant?” The webinar will take place on Thursday, February 16th from 10:00 AM – 11:00 AM Central Standard Time (CST). To see more information or register for the event, visit www.farrapc.com/rule6x.

The EPA NESHAP standard is a sweeping new requirement that impacts thousands of companies in the metalworking industries. This free webinar is designed to help metalworking professionals to understand and comply with the new EPA regulation, which imposes stringent requirements for the exhausting of welding fumes and other processes that may contain hazardous air pollutants.

This one-hour interactive webinar will explain the regulation and how to determine if your facility is impacted; the monitoring and test methods required for compliance; and equipment strategies that can help achieve compliance while also reducing energy costs. The speaker will be Greg Schreier, metalworking market manager for Camfil Farr APC and a frequent speaker on regulatory topics. This webinar will be available for viewing on-demand after the event, with registration.
