Dust Mitigation Strategies

Goals

To provide an overview of the challenges faced in dust mitigation by the dry processing and bulk solids industries, from a review of articles and/or case studies in trade or academic journals related to these industries.

Early Findings

Mitigating Dust

  • Manufacturing.net lists facility housekeeping, dust containment, and selecting the best mitigation equipment as dust mitigation options for dust management in food processing facilities.
  • Facility housekeeping refers to continued and comprehensive housekeeping from floor to ceiling to identify and correct dust accumulation.
  • Dust containment addresses how dust is removed from the facility. Airflow is an important consideration when choosing a dust collector regardless of whether the option chosen is housed indoors or outdoors.
  • Indoor installations are favored in the food processing industry because of their ability to prevent cross contamination among different products, to clean the dust at the point of creation to prevent greater dispersal in the facility, and to provide reduced downtime when several smaller systems are used in place of a larger centralized system.
  • Investing in the protection equipment helps to limit damage. Protection equipment can be directed at isolating the damage, using explosion vents, and using explosion suppression equipment.

Choosing a Dust Collector

  • Factors to consider when choosing a dust collector include being familiar with the type of dust generated at the facility and the requirements for treating that type of dust, the best type of technology to be used in managing the dust, the spatial requirements for the dust systems relative to the size of the facility, and the total cost of the system.

Dust Mitigation Resources

Case Study

  • After a grain dust explosion at a milling facility in Chicago, the managing engineer at the plant suggested that a mitigation strategy to employ when reactivating a facility would be to approach the reactivation like a plant startup instead of simply turning on the switch for the machinery.

Summary

  • The initial hour of research focused on providing an overview of dust mitigation strategies employed in food processing, resources to be used in developing the mitigation process, and a strategy to deploy arising from a case study of an incident caused by dust.
  • During the initial hour of research information on the requested topic was available.
  • Please advise in the section below the research should proceed.
  • Please advise whether research should be on a global scale or should it be limited to the dry processing and bulk solids industries in the US only.
