The Deadline for DHAs Has Passed

If your facility generates combustible dust or particulate solids, NFPA 652 says your Dust Hazard Analysis (DHA) was due on September 7, 2020. DHAs must be done every five years to stay compliant.

Not sure what to do? ACS is here to help.

Take action before the next deadline

Test for combustibility

Not sure if your plant generates combustible dust? It’s your responsibility to find out. Contact a lab to get your materials tested.

Identify dust hazards

The DHA can be done by a qualified consultant or in-house team who knows the process. They will identify any fire, deflagration and explosion risks in the facility.

Get equipped for action

You must demonstrate an effort to correct the hazards identified by the DHA. That may mean changes in your plant layout, equipment or housekeeping procedures.
