Combustible Dust Test Planning
Start with the End Game in Mind
Facilities that handle or generate dust as part of their process are at risk of explosion and fires. In order to mitigate these adverse events, companies must create an appropriate strategy for controlling combustible dust hazards.
OSHA NEP, NFPA, and other sources list a variety of possible combustible dust characterization tests that aid in the creation and continuity of suitable dust safety strategies.
This may include such tests as the Minimum ignition energy (MIE), Minimum ignition temperature (MIT), Minimum explosible concentration (MEC) and Percent moisture content, to name a few.
However, conducting all the listed tests isn’t the most sustainable option for many businesses and is usually not necessary. Undertaking an expansive range of testing not only impacts project completion time frames, but comes with accompanying financial costs.
Understanding combustible dust
Any substance that has the potential to become dispersed and suspended through the air as a dust cloud, ignite, and explode when exposed to an ignition source is considered to be combustible dust and may produce an explosion hazard.
As stated by OSHA, “Combustible dusts are fine particles that present an explosion hazard when suspended in air under certain conditions. A dust explosion can cause catastrophic loss of life, injuries, and destruction of buildings.”
Most materials are combustible in fine form, and some examples include:
• Metal
• Wood
• Coal and carbon
• Plastic
• Biosolid
• Organic
• Textile
• Agricultural (corn, wheat, sugar)
However, those materials that may not “normally” be combustible, can burn or explode if the dust particles are at the right size and concentration.
Combustible Dust Planning Presentation
The Combustible Dust Test Planning presentation lays out a risk-based approach to deciding which tests are important for specific applications, that can be applied to a number of industries.
This education session will provide an understanding of:
Recognizing potentially combustible dust
Articulating the importance of dust characterization and material properties
Identifying the data behind fire, flashfire, and explosion hazards of combustible dusts
Recalling the current status of codes and standards
Recalling recognized and generally accepted good engineering practices, RAGAGEP
How to assess what tests are available
How to develop a new test proposition
Samples to test – equipment application and which sources of ignition may be present
How to prepare samples
Tests to conduct and what the report data represents
Documenting an effective sampling plan
Who will benefit:
Managers
Supervisors
Engineers
Safety personnel
