Does a new facility need a DHA?

A new process should address combustible-dust hazards during design, before assumptions become installed equipment. If combustible or explosible particulate solids may be present, establish material data, process scenarios, applicable requirements, and protection strategy early, then confirm the final installed condition before operation.

Define materials, scenarios, and requirements Carry assumptions into equipment specifications Verify the installed system and close findings

The source links below support the regulatory, standards-development, investigation, or test-characteristic context stated on this page. DustDHA does not reproduce paywalled standard text and does not turn general source material into a facility-specific engineering conclusion. Where a fact depends on the current NFPA 660 edition, use the official NFPA publication and record the edition reviewed.

Record the material form, process conditions, equipment and enclosure, current safeguards, authority having jurisdiction, and the evidence used. Separate verified facts from assumptions. If a decision affects life safety, explosion protection, code compliance, or a signed engineering deliverable, have a qualified professional evaluate the actual site rather than relying on this summary.
