Combustible dusts can fuel a flash fire or explosion when dispersed in a dust
cloud. Workers in many industries who handle combustible solids may be exposed
to combustible dust incidents that can cause catastrophic destruction, injuries
and deaths. Employers and workers should take steps to control the fuel and
prevent tragic consequences.

Workers must be protected from combustible dust flash fire and explosion
hazards. Employers should determine whether dusts present in the workplace are
explosible. If so, they must take proper precautions to protect workers against
flash fires and explosions.

The fact sheet explains how to capture, contain and clean combustible dusts
generated in a variety of workplaces before they become dispersed in clouds
that present the risk of flash fires or explosions.
