Dust Hazard Analysis
If your facility stores, handles or processes combustible materials, NFPA 652 requires a Dust Hazard Analysis (DHA) to be completed and documented into a final report. Fike offers DHA services to ensure the safety of your employees and the financial protection of your business.
Steps To Complete Your DHA
Identifying Your Hazards
A walkthrough of your facility and review of process flow diagrams to understand how combustible material is conveyed, where dust clouds develop and where ignition sources may exist.
Analyzing Your Dust
Identifies where in your process dust is being introduced or emitted and reviews the documented explosibility of such dust; if necessary, dust testing is performed.
Reviewing Your Safeguards
Evaluates your safety systems and processes to ensure they are compliant and effective; housekeeping and cleaning efforts are reviewed to reduce the risk of secondary explosions.
Prioritizing Recommendations
An action plan is developed to prioritize the areas of the process which should be addressed immediately, based on the likelihood of a hazard occurring and the severity of its consequences.

DHA Frequently Asked Questions
NFPA 652 includes very specific language regarding DHAs.
- Who is required to comply with NFPA 652 and complete a DHA?
-
“This standard shall apply to all facilities and operations that manufacture, process, blend, convey, repackage, generate, or handle combustible dusts or combustible particulate solids.” (NFPA 652 – 1.3.2)
- What DHA documentation is required?
-
“Test results, historical data, and published data shall be documented and, when requested, provided to the authority having jurisdiction (AHJ).” (NFPA 652 – 5.2.2)
- If my industrial process has never had an incident, do we still need to complete a DHA?
-
“The absence of previous incidents shall not be used as the basis for deeming a particulate to not be combustible or explosible.” (NFPA 652 – 5.2.3)... “The absence of previous incidents shall not be used as the basis for not performing a DHA.” (NFPA 652 – 7.1.3)
- How often does a DHA need to be performed or updated?
