Dust Explosion Testing Mandated by New OSHA National Emphasis Program Performed by Fauske & Associates, LLC Ahead of Congressional Legislation


Congress is currently voting on the "Worker Protection Against Combustible Dust Explosions and Fires Act of 2008" following new OSHA standards. Fauske & Associates, LLC has been performing workplace dust explosive safety testing for years, setting the standard long before disasters occurred. FAI is the leading authority in chemical and nuclear safety testing.

Burr Ridge, IL, August 02, 2008 --(PR.com)-- Dust explosions are a serious hazard in industries nationwide. They lead to the loss of production, plant/facility destruction and personnel injury or fatality.

In 2005, the US Chemical Safety and Hazard Investigation Board issued a report stating that between 1980 and 2005, at least 281 deadly dust explosions occurred in the U.S., killing 119 people and injuring 718 others while extensively damaging or destroying facilities. Congressional hearings led to the severe criticism of OSHA for lack of vigilance by the US Chemical Safety Board. As a result, in October 2007, OSHA initiated a National Emphasis Program to lead their inspectors in cracking down on dust explosion hazards.

OSHA Directive Number: CPL 03-00-006 states: “This directive contains policies and procedures for inspecting workplaces that create or handle combustible dusts. In some circumstances, these dusts may cause a deflagration, other fires, or an explosion.”

In the wake of February’s catastrophic explosion killing 11 at the Imperial Sugar Company Port Wentworth Refinery, the OSHA mandate follows what many experts believe to be a no-brainer for all facilities creating dust particles. The entire industry is now awake and has resulted in additional Congressional hearings.

Possible combustible dust facilities or plants are those handling chemical, metal and plastic dusts such as:

Agricultural Produce Packaging and Powder Handling Facilities
Agglomeration & Briquetting Facilities
Brick/Clay/Ceramic Industry Plants
Carbonaceous Dust-Handling Plants/Manufacturers
Commercial and Residential Furniture Manufacturing Plants
Construction and Demolition Recycling Facilities
Erosion Industry Facilities
Filtration Plants
Hardware Manufacturing Facilities
Industrial Hygiene Facilities
Pharmaceutical Manufacturing Facilities
Small shop – e.g. Woodworking/Cabinetry Facilities
Valves, Gates, Airlock Facilities

According to Ashok Ghose Dastidar Ph.D., MBA, Acting Manager, Dust & Flammability Testing and Consulting Services for Fauske & Associates, LLC, “to meet OSHA compliance companies must know their dust explosion hazard potential and address the risk – or face OSHA citations. FAI offers consulting services to assess companies’ compliance with the OSHA NEP by providing the full suit of dust explosibility tests required to characterize the material explosion hazard potential. FAI provides Dust Explosion Testing for the OSHA National Emphasis Program addressing deflagration, other fire, and combustible dust explosion hazards.”

Years ahead of OSHA’s new standards, FAI led the industry by performing existing ASTM (American Society for Testing and Materials) and NFPA (National Fire Protection Association) standard testing for their customers. FAI’s dust sample testing includes:
1) Dust Explosivity: Examines and analyzes explosive characteristics of the dust sample.
2) Minimum Ignition Energy, MIE: Identifies minimum energy required to ignite a dust cloud. (Examines sample sensitivity to ignition from electrostatic discharge.)

3) Minimum Autoignition Temperature, MAIT: Identifies the minimum temperature at which a dust cloud will autoignite.
4) Minimum Explosive Concentration, MEC: Identifies the minimum explosive concentration of a dust cloud.

5) Hot-Surface Ignition Temperature of Dust Layer: Identifies the minimum temperature at which a dust layer will ignite.
6) Limiting Oxygen Concentration: Identifies the minimum oxygen concentration at which a dust can explode.
7) Drop Impact: Identifies the impact force required to ignite a dust layer.
8) Friction Sensitivity: Identifies the frictional force required to ignite a dust layer.
9) Volume and Surface Resistivity: Measures the conductivity of a dust sample.
10) Dielectric Constant: Identifies AC loss characteristics and permittivity of dust sample.
11) Differential Scanning Calorimetry, DSC: Identifies the temperature range at which the dust sample undergoes exothermic decomposition or is susceptible to oxidation along with the specific heat of the sample.
12) Accelerating Rate Calorimetry: Identifies the dust samples onset temperature for exothermic activity.
