The Challenge Is Real

Are You Prepared to Lead a Dust Hazard Analysis?

Dust Hazard Analyses are now a regulatory requirement under NFPA 652 and NFPA 660 — yet many facilities struggle to find qualified professionals who can lead them effectively. The consequences of a poorly conducted DHA are severe: missed hazards, non-compliance, and ultimately, increased risk of a catastrophic dust explosion.

Most safety professionals are expected to lead or support DHAs without formal, structured training. They piece together knowledge from standards and on-the-job experience, often without the proven workflows, templates, and facilitation skills needed to do the job right.

The CDHA™ program closes that gap. This focused, self-paced certification gives you the specific DHA knowledge, facilitation skills, and practical tools you need — and the credential to prove you are ready to lead.

What You Will Gain

Build the Skills That Matter Most

DHA Leadership Skills

Master the full DHA process — from hazard identification and dust sampling to ignition source evaluation and mitigation strategy selection — so you can lead analyses with confidence.

Practical Tools & Templates

Go beyond theory with proven DHA workflows, hazard identification checklists, and real-world examples you can apply directly at your facility or for your clients.

Industry-Recognized Credential

Earn the CDHA™ designation — a credential that demonstrates your expertise in leading Dust Hazard Analyses and your commitment to NFPA compliance and worker safety.

Flexible, Self-Paced Learning

100% online with no travel required for the core courses. Work through the program on your own schedule, with 12 months of access and ongoing instructor support.

Program Curriculum
