On Demand Webinar: Dust Hazard Assessments - An Introduction

Dust explosion test data must be available on all materials and powders in order to undertake a Dust Hazards Analysis (DHA). For an evaluation of potential dust fire and explosion hazards, a comprehensive DHA is used to effectively identify and manage potentially hazardous materials in your workplace.

The material testing data is required by NFPA 652: Standard on the Fundamentals of Combustible Dust. This standard requires facilities that contain combustible solids, powders or dust undertake a DHA to comply. The data can be obtained by conducting relevant laboratory testing on material samples from your facility.

What you’ll learn:

  • Testing protocols for determining dust fire and explosion risks during operations
  • The establishment of safety parameters.
  • Powder and dust ignition sensitivity and the type of ignition sources associated with operational equipment.
  • Factors affecting the ignition sensitivity, explosion severity, and self-heating characteristics of powders.

This webinar is best for:

  • HSE Directors and/or managers
  • Process and HSE Professionals
  • Plant Managers
  • Project Managers and Risk Assessors


This webinar will explain just how cost and time effective it can be to support a DHA by identifying both the most relevant and baseline test data required to comply with NFPA 652.
