Combustible Dust Hazards

Know your risk to prevent dust explosions with the help of our combustible dust services

Combustible Dust Hazards

Organizations that are aware of the hazards of combustible dusts and how to manage or eliminate the dangers they pose can effectively avoid the catastrophic effects of dust explosions. These could include loss of life and property, injury, damages, interrupted production, litigation and adverse publicity.

DEKRA has years of experience testing and consulting on combustible dust hazards. We offer a comprehensive package of services, helping you to identify hazardous materials and to assess associated risks.

The knowledge and resources we bring in as a global organization make us a natural choice for companies looking for a reliable partner to address combustible dust challenges. Our laboratories are ISO/IEC 17025 accredited, and we can offer GLP laboratory testing through our Southampton, UK facility. DEKRA's process safety experts combine the highest qualifications with experience and a real passion for the teamwork it takes to design sustainable safety solutions.

Consultancy advice and top-of-the-line combustible dust testing

Services for Combustible Dust Testing

Our portfolio of services related to combustible dusts reflects our comprehensive approach to safety, encompassing consulting, testing and training. We offer expertise in:

  • Hazard Identification
  • Determining Combustibility and Explosibility Hazards
  • Dust Hazard Analysis (DHA)
  • Dust Hazard Management
  • Training and Competence Development
  • NFPA 652 Compliance

One of our consulting teams can help you select the most appropriate tests and the most cost-effective manner to respond to your needs. The tests we offer include:

Dust Explosion Screening

  • Group Go/NoGo Classification: determines whether a powder or dust is explosible (Go) or non-explosible (No Go) when exposed to an ignition source when in the form of a dust cloud.

Ignition Sensitivity

  • Minimum Ignition Energy (MIE): determines the minimum energy of an electrostatic or mechanical spark capable of igniting dispersed dust under ambient conditions.
  • Minimum Ignition Temperature (Cloud): determines the minimum temperature of a hot surface capable of igniting a dust cloud
  • Minimum Ignition Temperature Layer (MIT Layer): determines the minimum temperature of a hot surface capable of igniting a powder layer

Flammable Limits

  • Limiting Oxygen Concentration (LOC): determines the highest oxygen concentration at which ignition of dispersed dust at ambient temperature and pressure is not possible.
  • Minimum Explosible Concentration (MEC): determines the minimum concentration of a dust at which ignition is possible.

Explosion Severity

  • Dust Explosion Severity: measures a powder’s explosion severity according to specific pressure parameters
