OSHA Grain Facility Standard-Poor Results

Since the OSHA grain facility standard was promulgated in 1987 agricultural dust explosions, fatalities, and injuries have continued at nearly the same rate as general industry combustible dust explosions For example, utilizing data compiled by Dr. Robert W. Schoeff, Kansas State University, in cooperation with FGIS-USDA, during the period 1980-2005 there as been on the average of 15 annual agricultural dust explosions at grain elevators, corn processors, feed, flour and rice mills.

General Industry Explosions










In contrast, the Chemical Safety Board completed a two year study which spanned the same period while investigating dust explosions in general industry and determined on the average 11 dust explosions occurred annually. So how is it that a multitude of agricultural dust explosions are still occurring even after an OSHA grain facility standard was implemented over two decades ago.?

In all fairness, since the grain standard was instituted in 1987, fatalities and injuries from agricultural dust explosions have been reduced by nearly 50 % , with incidents decreasing by 30 % on an annual average. But why is there still an explosion occurring nearly every month somewhere across our nations' heartland?

Current OSHA health and safety regulations are clearly not preventing workplace injuries and fatalities. Most recently, from the ten year period 1996-2005, there were 106 grain facility dust explosions, resulting in 16 fatalities and 126 injuries, resulting in over $ 162 million dollars in economic damage.

So should it be up to the federal government to reduce further dust explosions in all industries; especially if current regulations are not working ? Many stakeholders believe governmental regulatory intervention is counterproductive and only raises the cost of business operations resulting in higher prices in finished products to the consumer.

An entire review and governmental audit of current OSHA grain facility standards is in order. The time has come in providing business management personnel and the workforce with updated Material Safety Data Sheets (MSDS)'s, which provide information on the explosive properties of all combustible particulate solids like corn, soybeans, wheat, etc. Information such as minimum explosive concentration (MIC), minimum ignition temperature (MIT), and KSt (normalized rate of pressure rise) included in the MSDS's would be beneficial in the hazard communication process.
