Course Description

Many facilities manufacture materials in the form of powders and some facilities generate powders through handling and processing solid materials. Such facilities may be subject to combustible dust hazards. A combustible dust is a finely-divided particulate solid that presents a flash-fire hazard or explosion hazard when suspended in air, or another oxidizing medium. A wide variety of industries pose combustible dust hazards from various materials including chemicals, metals, wood, plastics, rubber, coal, flour, sugar, and paper.

This course teaches participants how to perform a Dust Hazard Analysis (DHA) and Dust Risk Assessment (DRA) to comply with the requirements of NFPA 652:2016, Standard on the Fundamentals of Combustible Dust. A DHA is a systematic review to identify and evaluate the potential fire, flash fire, or explosion hazards associated with the presence of one or more combustible particulate solids in a process or facility. A DRA estimates the likelihood, vulnerability, and magnitude for incidents that could result from exposure to hazards. Course attendees participate in workshops to practice use of the methods taught.

You will learn:

  • Basics of combustible dust safety
  • NFPA standards requirements for DHA and DRA
  • Which additional standards may apply
  • Qualifications for study facilitators
  • Pre-requisites for DHA
  • Scope of DHA
  • Key DHA elements
  • Methods for DHA and DRA
  • How to prepare for studies
  • What information to assemble
  • Who should participate in studies
  • How to partition facilities for study
  • What scenario information should be recorded
  • What steps are involved in performing studies
  • What should be documented in a study report
  • What follow-on studies are needed


Be able to effectively and efficiently perform dust hazard analysis and risk assessment for industrial facilities.
