The request
“A fault tree for grain silo dust explosion or fire: explosion needs a combustible dust cloud, ignition and confinement; fire needs dust accumulation and ignition. Ignition comes from a mechanical spark, electrical arc, hot surface or static discharge.”
Then tryAdd poor housekeeping as a cause of dust accumulation.Add a spark detector as a control measure note.
What is in this drawing
Read the decisions behind it.
01
Modeled explosion and fire as separate top-level branches sharing a common ignition gate
02
Used OR/AND gates with basic event probabilities to enable cut set and probability analysis
Suitable for any combustible dust handling facility where explosion and fire risks must be systematically assessed and mitigated.
