This chapter shall govern combustible dust-producing operations, and the equipment and processes utilized in connection with such operations in order to minimize and mitigate dust explosion hazards.
Permits shall be required as set forth in FC105.6.
Combustible dust-producing operations shall be conducted in accordance with this chapter. All devices, equipment, systems and processes utilized in connection with such operations shall be designed, installed, operated and maintained in accordance with this chapter.
The following term shall, for the purposes of this chapter and as used elsewhere in this code, have the meaning shown herein.

COMBUSTIBLE DUST. Finely divided solid material that is 420 microns or less in diameter, will pass through a U.S. standard No. 40 sieve and, when dispersed in air in sufficient concentrations, can be ignited by a flame, spark or other source of ignition.
It shall be unlawful to smoke, or use heating or other devices employing an open flame or spark-producing equipment, in areas where combustible dust is generated, processed or otherwise stored, handled or used.
Accumulation of combustible dust shall be kept to a minimum indoors. Accumulated combustible dust shall be collected by vacuum cleaning or other means that will not place combustible dust into suspension in air. Forced air or similar methods shall not be used to remove dust from surfaces. When a normally inaccessible area such as a duct or cockloft is made accessible for purposes of an alteration, repair or other reason, any accumulation of combustible dust shall be removed from such area.
Measures shall be taken to prevent and control dust explosions wherever combustible dust-producing operations are conducted. Such measures shall comply with the applicable operation and maintenance requirements of the codes and standards listed in FC Table 1304.1.
