About Combustible Dust 

Combustible dusts are fine particles that could present an explosion hazard in certain conditions.  Dust explosions can occur in many places where there is oxygen, heat and dust (the fuel) in sufficient quantities and some kind of confined space.

Combustible Dust Triangle

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, pharamaceuticals, dyes, coal, metals (e.g., aluminum, chromium, iron, magnesium and zinc) and fuel power generation.

Osha's Combustible Dust National Emphasis Program applies to 64 industries.

Dust Control Measures

The dust-containing systems (ducts and dust collectors) are designed in a manner that fugitive dusts are not allowed to accumulate in the work area.

The facility has a housekeeping program with regular cleaning frequencies established for floors and horizontal surfaces, such as ducts, pipes, hoods, ledges, and beams, to minimize dust accumulations within operating areas of the facility.

The working surfaces are designed in a manner to minimize dust accumulation and facilitate cleaning. 

Ignition Control Measures

Electrically-powered cleaning devices such as vacuum cleaners, and electrical equipment are approved for hazard classification for Class II locations.

The facility has an ignition control program, such as grounding and bonding and other methods, for dissipating any electrostatic charge that could be generated while transporting the dust through the ductwork.

The facility has a Hot Work permit program.

Areas where smoking is prohibited are posted with "No Smoking" signs.

Duct systems, dust collectors, and dust-producing machinery are bonded and grounded to minimize accumulation of static electrical charge.

The facility selects and uses industrial trucks that are approved for the combustible dust locations.

Prevention Measures

The facility has separator devices to remove foreign materials capable of igniting combustible dusts.

MSDSs for the chemicals which could become combustible dust under normal operations are available to employees.

Employees are trained on the explosion hazards of combustible dusts.

Protection Measures

The facility has an emergency action plan.

Dust collectors are not located inside of buidlings.  (Some exceptions)

Rooms, buildings, or other enclosures (dust collectors) have explosion relief venting distributed over the exterior wall of buildings and enclosures.

Explosion venting is directed to a safe location away from employees.

The facility has isolation devices to prevent deflagration propagation between pieces of equipment connected by ductwork.

The dust collector systems have spark detection and explosion/deflagration suppression systems.

Emergency exit routes are maintained properly.
