Combustible Dust

Any combustible material can burn rapidly when in a finely divided form. If such a dust is suspended in air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces (such as aluminum or iron), given the proper conditions, can be explosible in dust form.  There is no one OSHA standard for combustible dust hazards; however, combustible dust is addressed in several existing OSHA standards.  Dust can seem unassuming, but don’t let complacency lead to a catastrophic incident.
