The National Fire Protection Association (NFPA) has changed the way industries manage combustible dust and particulate solid hazards by replacing six separate combustible dust standards with one consolidated and streamlined scheme. Effective December 6, 2024, NFPA 660: Standard for Combustible Dusts and Particulate Solids is intended to eliminate variability across previous standards, providing industries with clearer and more consistent guidelines to managing combustible dust hazards. Below we provide an overview of combustible dusts, a description of the new standard, a summary of the ways in which combustible dust hazards are managed by regulators like OSHA and the CSB, as well as employer takeaways.
Overview of Combustible Dusts
As we explained in our webinar, broadly, combustible dusts are finely divided combustible particulate solid that presents a flash fire hazard or explosion hazard when suspended in air under certain conditions.
Combustible dusts can include dusts of grains, sugar, corn starch, cotton, metals, pharmaceuticals, plastics, carbon, and wood, among others. Given the wide range of dusts that might be combustible, it is not surprising that numerous industries are affected by combustible dust hazards, including, but not limited to, chemical manufacturing, food products, metal industries, rubber and plastic products, equipment manufacturing, lumber and wood products, etc.
Although combustible dust incidents may Continue reading
