This course will ensure all participants are aware of important issues associated with the NFPA Combustible Dust Standards and the OSHA Combustible Dust National Emphasis Program. A logical approach to characterizing a dust’s or powder’s hazardous properties will be presented, as well as a description of various techniques used to avoid and/or control dust explosions in a safe and compliant manner. After an introduction to the fundamentals of combustible dust fires and explosions, the course will provide a review of recent dust explosions with lessons learned, testing requirements to characterize potential combustible dusts, tips for effective combustible dust compliance inspections, strategies on how to comply with NFPA codes and prepare for an OSHA combustible dust compliance inspection, as well as various mitigation technologies.
