Catastrophic dust explosions in 2003 and 2008 have placed an increased emphasis on the prevention and mitigation of dust explosions. In response to these incidents and subsequent CSB recommendations, OSHA has introduced a Combustible Dust National Emphasis Program (NEP) and has greatly increased enforcement efforts. In this presentation, Dr. Timothy Myers provides the background on dust explosions, the elements required to cause them, and the types of materials that can fuel them. He reviews the current status of dust explosion regulations and consensus standards in the United States. He presents statistics of OSHA enforcement issues, including descriptions of the most frequently issued citations. He summarizes NFPA standards for the prevention and mitigation of dust explosions, including primary prevention methods.
