While there is no universally-accepted definition of just exactly what combustible dust is comprised of, almost anyone you talk to has an immediate perception of it being something that is very fine in size and very explosive in character.

The NFPA National Fire Protection Association) also states that "Any material that will burn in solid form, in the open air, can also be explosive in dust or particulate form". This is sometimes referred to as deflagration and can take place whenever solids are released into the atmosphere as fine dust. To learn more about combustible dust, check out this informative article: https://www.5snews.com/dangers-combustible-dust-within-workplace/ .

The common types of combustible dusts that we are most familiar with include various metals, wood, plastic, rubber, coal, flour, sugar, and paper. While this is not a comprehensive list, these are some of the most common materials and most are present to some degree in our modern day manufacturing plants and industrial facilities.

We at Creative Safety Supply hope that you find this slideshare informative and helpful and that it might also spur you or your safety manager(s) to take a closer look at possible dust hazards lurking in YOUR facility.
