What happens after combustible-dust testing?

Validate the sample identity and method, then map each result to the process and decision it was ordered to support. Update the DHA inputs, ignition-source evaluation, protection design assumptions, operating controls, or need for more representative sampling. Do not file the report without resolving what it changes.

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.
