Description
This webinar provides a step by step overview of Dust Hazard Analysis requirements and best practices for facilities that handle combustible particulate solids. The presenters explain how to determine dust combustibility, how DHA requirements apply under NFPA 652 and industry specific NFPA standards, and what OSHA enforcement and insurance carriers expect from facilities. The session covers testing needs, DHA methodology, common deficiencies, mitigation technologies, and real world considerations for achieving and documenting compliance.
Key Topics Covered
- Origins of DHA requirements and lessons from historical dust explosions
- Overview of NFPA 652 and industry specific NFPA standards for combustible dust
- Determining dust combustibility through testing or NFPA reference tables
- DHA methodology, documentation expectations, and five year revalidation
- Common gaps including housekeeping, MOC, dust testing, and equipment data
- Explosion venting concepts, vent design, sensors, and NFPA 68 requirements
- Installation considerations, ducting, flameless vents, and prevention methods
- Inspection, maintenance, and recordkeeping obligations for vents and protection equipment
What You’ll Learn
- How to determine whether your facility handles combustible dust and what testing is required
- How DHA findings connect to housekeeping, grounding, area classification, and system ventilation
- How to evaluate dust collectors, baghouses, silos, and other equipment for deflagration risks
- How NFPA 68 guides explosion vent sizing, activation pressure, installation, and sensors
- How to prepare documentation for fire marshals, OSHA inspectors, and insurance reviews
- How to identify when equipment, process changes, or new dust data require DHA updates
