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.
Combustible dust-producing operations, including manufacturing, processing and handling 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.
Powder coating shall additionally comply with the requirements of FC Chapter 24.
Operations that produce deflagrable wood dust shall additionally comply with the requirements of FC Chapter 28.
Special effects utilizing combustible dust shall additionally comply with the requirements of FC Chapter 56.
The following terms shall, for the purposes of this chapter and as used elsewhere in this code, have the meanings set forth in FC202.
DEFLAGRABLE WOOD DUST.
DEFLAGRABLE WOOD DUST.
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.
An approved dust collection system shall be installed and/or other measures taken to collect and otherwise manage combustible dust generated by combustible dust-producing operations in order to prevent or mitigate combustible dust explosions. Facilities in which combustible dust-producing operations are to be conducted shall be designed, installed, operated and maintained in accordance with the industry or product-specific standards set forth in FC Table 2204.1.

A dust hazard analysis shall be conducted in accordance with NFPA 652 upon commencement of combustible dust-producing operations for any operation generating visible atmospheric dust and/or dust accumulations at locations other than the point of dust generation, to determine whether:
- the equipment designed and installed to collect combustible dust and other mitigation measures is effective in achieving its design objectives and is preventing fugitive dust; or
- the operation is generating an amount of combustible dust as to require the installation of combustible dust collection equipment and other mitigation measures.
