standards (Appendix D). Kentucky OSH issued other citations for inadequate ventilation and unapproved
electrical equipment in areas where combustible dusts were present.
Following the West Pharmaceutical dust explosion, the North Carolina Department of Labor (2003)
issued an industry alert on combustible dust hazards. Kentucky OSH has issued no educational material
to alert employers of the dangers of combustible dusts.
Federal OSHA has adopted regulations that address the prevention of dust explosions in certain business
sectors, including grain-handling facilities; pulp, paper, and paperboard mills; bakeries; and sawmills. In
addition, it has adopted general industry regulations to control certain activities such as the use of
electrical equipment and forklifts in environments that may contain combustible dusts.
In 29 CFR 1910.272(j)(3), OSHA requires that grain-handling facilities have a written housekeeping
program that sets the frequency and methods for controlling dust on exposed surfaces. These facilities
must remove dust whenever it exceeds 0.125 inch in priority areas. In the grain standard, OSHA also
warns that using compressed air for cleaning combustible dust can be hazardous if all potential ignition
sources are not removed or controlled.
Although both OSHA and the Kentucky Occupational Safety and Health Standards Board have adopted
certain NFPA standards, neither has adopted NFPA 654 (2000)—which addresses dusts such as those
found at CTA. NFPA 654 lists specific design and work practice precautions (Appendix D).
