Dust Hazard Analysis Training
Testing your own powder, and the layer arithmetic that decides housekeeping
Covers the dust hazard analysis required for facilities handling combustible particulate solids. Delegates work through the cubic law and Kst classification, the properties that decide whether ignition is credible, and the layer accumulation calculation that separates a survivable primary event from a fatal secondary one.
This course sits alongside our Dust Explosion Hazard Assessment consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
The explosion pentagon
- Fuel, oxidant, dispersion, confinement and ignition source
- Which side is realistically removable in your process
- Why ignition control alone is the weakest strategy
Material properties
- The cubic law and what Kst actually represents
- St classification and why class sets severity rather than likelihood
- Minimum ignition energy, minimum ignition temperature for cloud and layer
- Minimum explosible concentration and limiting oxygen concentration
- Why handbook values describe someone else's powder
Secondary explosions
- The layer thickness calculation and comparison against minimum explosible concentration
- Housekeeping action levels and what a sub millimetre layer means
- Imperial Sugar and the sequence from primary to secondary
- Inspecting the surfaces nobody looks at
Protection and the analysis itself
- Deflagration venting, suppression and isolation selection
- Inerting where it is practical
- Conducting and documenting a dust hazard analysis
- Ignition source control including static, friction and hot work
What you receive
- A dust hazard analysis worksheet
- A material testing specification for your own powders
- A layer accumulation calculation tool
- A housekeeping inspection scope covering elevated surfaces
- Assessment result and attendance record
What changes afterwards
- Material properties come from testing your powder as it exists at the fines point
- Housekeeping becomes a quantified control rather than a tidiness expectation
- Protection is selected against measured Kst and Pmax
- The dust hazard analysis satisfies scrutiny rather than filling a file
