PDC 105
Implementing a Combustible Dust Program

introductory | 1.34 CM Points/ 8 Contact Hours/ 1.0 CEU/COC Point | Saturday | 8:00 a.m. - 5:00 p.m. | Limit: 45

Online Community

Engineering, Legal, Regulatory, Guidelines and Standards

OSHA will be issuing combustible dust regulations in the next year or two. Industrial Hygienists will probably be involved in efforts to implement Combustible Dust Programs at their sites.

Participants will get a practical perspective on how to assess combustible dust hazards and to identify gaps in site capabilities as compared to OSHA and NFPA requirements as they build towards a comprehensive combustible dust program. The learnings about combustible dust risk assessment and mitigation techniques will be reinforced through a case study of a simple powders process.

Experience in performing exposure assessments; familiarity with industrial ventilation system design concepts.

Learning Aids:
Participants must bring OSHA Combustible Dust National Emphasis Program Directive of 3/11/08 and a scientific calculator.

Upon completion, the participant will be able to:

  • Outline the key elements needed to implement a combustible dust program that meets OSHA and National Fire Protection Association (NFPA) requirements.
  • List testing methods used to describe combustible dust hazards.
  • Explain the details that must be addressed when implementing a combustible dust program.
  • Identify possible ignition sources and control techniques.
  • Describe equipment commonly used to mitigate combustible dust risks.
  • Discuss inspection points for an OSHA combustible dust inspection.
  • Cite NFPA standards that apply to combustible dust.


  • Introduction and conditions necessary for combustible dust deflagrations
  • OSHA Combustible Dust National Emphasis Program inspections
  • Combustible dust hazard characterization tests and their application towards safe design and operation.
  • Case study: Assessing the likelihood that combustible dust requirements apply
  • Control of fugitive dusts
  • Review of ignition sources and controls
  • Case study: Identifying locations with potential to form dust clouds in the presence of ignition sources
  • Explosion Prevention, Protection, Isolation Options
  • Case study: Potential application of explosion prevention, protection, and isolation techniques
  • OSHA and NFPA combustible dust procedures
  • Overview of NFPA standards and other consensus standards and guidelines
  • Case study: Gap analysis and wrap-up

Transfer of Knowledge:
Instructors will evaluate participants understanding of the materials presented based on:

  • Practice exercises
  • Group activities 

The following instructors have disclosed significant financial interests or other relationships including grants, research support, employment, consulting, major stockholder, speakers bureau member, etc. with manufacturers/ providers of commercial products and services.

Gary Johnson, PE – My experience comes from being a consultant providing services to industrial clients for dust collection system and combustible dust assessments and improvements and training. I do not have any ties to manufacturers of commercial products.
