Any combustible material (and some materials normally
considered noncombustible) can burn rapidly when in a finely divided form. If
such a dust is suspended in air in the right concentration, it can become
explosive. The force from such an explosion can cause employee deaths, injuries,
and destruction of entire buildings. Such incidents have killed scores of employees
and injured hundreds over the past few decades.
Materials that may form combustible dust include metals (such as aluminum and
magnesium), wood, coal, plastics, biosolids, sugar, paper, soap, dried blood,
and certain textiles. In many accidents, employers and employees were unaware
that a hazard even existed.
A combustible dust explosion hazard may exist in a variety of industries,
including: food (e.g., candy, sugar, spice, starch, flour, feed), grain,
tobacco, plastics, wood, paper, pulp, rubber, furniture, textiles, pesticides,
pharmaceuticals, dyes, coal, metals (e.g., aluminum, chromium, iron, magnesium,
and zinc), and fossil fuel power generation.
