Dust Hazard Analysis
What a DHA is, who performs it, and what it means for your housekeeping equipment.
A Dust Hazard Analysis is the systematic review NFPA 652 requires wherever combustible dust may be present: identifying the materials, the locations where they accumulate or become airborne, the ignition sources nearby, and the safeguards in place. It is performed by, or under the direction of, a qualified person — often a process-safety consultant working with plant engineering — and it becomes a living document, revisited on at least a five-year cycle.
The output is a list of scenarios and actions. Housekeeping appears in almost every one, because settled dust is both the fuel for secondary explosions and the most controllable variable in the analysis.
That is where equipment selection enters: the DHA defines the material properties and area classifications, and the recovery equipment must be engineered against them. PrestiVac works from your DHA's findings to specify systems — and provides the supporting documentation your action items require.
