What is Combustible Dust?

A finely divided combustible particulate solid that presents a flash fire hazard or explosion hazard when suspended in air or the process-specific oxidizing medium over a range of concentrations.

Our DHA Process

Qualified Person

NFPA’s Standard on the Fundamentals of Combustible Dust (NFPA 652-2019) and the other commodity-specific combustible dust standard require that the Dust Hazards Analysis (DHA) be performed or lead by a qualified person. These standards define a qualified person as “a person who, by possession of a recognized degree, certificate, professional standing, or skill, and who, by knowledge, training, and experience, has demonstrated the ability to deal with problems related to the subject matter, the work, or the project.” 


The individual(s) performing the DHA not only has the greatest effect on the quality of the DHA, but also the safety of any employees affected by these hazards. Thus, Airdusco believes that the expertise and experience that comprise an individual’s qualifications go well beyond a definition and are gained from years of experience assessing and mitigating complex combustible dust hazards. Each of Airdusco’s Dust Consultants have performed numerous DHAs to develop safe, cost-effective solutions for the potential fire, deflagration, and explosion hazards associated with agricultural (food), metal, wood, plastic, pharmaceutical, and other combustible dusts. The totality of combustible dust knowledge and expertise possessed by our consultants is unrivaled, which is evident in the quality and thoroughness of Airdusco’s DHA process.

Is My Dust Combustible?

The first step in the mitigation of combustible dust hazards is to know whether your dust is combustible. This can be a confusing process, but we can help you by developing a dust testing strategy. We can advise where you need to collect samples, what tests you need to have run, and then interpret the test results. This is a critical step in developing your mitigation strategies going forward.
