Requires such standard to provide no less protection than the recommendations contained in the National Fire Protection Association's Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids-2006 (NFPA 654) and Standard for Combustible Metals-2006 (NFPA 484). Requires such standard to provide requirements for: (1) a combustible dust hazard assessment; (2) a written program which includes plans for hazardous dust inspection, testing, housekeeping, and control, with established frequency and methods; (3) engineering, administrative controls and operating procedures, such as means to controlling fugitive dust emissions and ignition sources, the use of dust collection systems and filters, minimizing horizontal surfaces where dust can accumulate, and sealing of areas inaccessible to housekeeping; (4) managing change of dust producing materials, technology, equipment, staffing, and procedures; (5) housekeeping to control accumulation of combustible dust; (6) building design; (7) explosion protection; (8) employee participation in hazard assessment, development of and compliance with the written program, and other elements of hazard management in this standard; and (9) providing safety and health information and training to employees.

Requires the Secretary, through OSHA, to modify the hazard communications standard to: (1) revise the definition of "physical hazard" to include "a combustible dust" as an additional example of a physical hazard; and (2) define "combustible dust" as a combustible particulate solid or finely divided metal that presents a fire or deflagration hazard when suspended in air or some other oxidizing medium over a range of concentrations regardless of particle size and shape.

Requires such standard to provide requirements for: (1) a hazard assessment to identify, evaluate, and control combustible dust hazards; (2) a written program that includes provisions for hazardous dust inspection, testing, hot work, ignition control, and housekeeping, including the frequency and methods used to minimize accumulations of combustible dust on ledges, floors, equipment, and other exposed surfaces; (3) engineering, administrative controls and operating procedures, such as means to control fugitive dust emissions and ignition sources, the safe use and maintenance of dust producing and dust collection systems and filters, minimizing horizontal surfaces where dust can accumulate, and sealing of areas inaccessible to housekeeping; (4) housekeeping to prevent accumulation of combustible dust in places of employment in depths that can present explosion, deflagration, or other fire hazards, including safe methods of dust removal; (5) employee participation in hazard assessment, development of and compliance with the written program, and other elements of hazard management; and (6) providing safety and health information and annual training to employees, including housekeeping procedures, hot work procedures, preventive maintenance procedures, common ignition sources, and lock-out, tag-out procedures.

Provides an exemption from otherwise applicable rulemaking requirements.

Provides that such interim standard shall have the legal effect of an occupational safety and health standard and shall apply until a final standard becomes effective.

Requires the Secretary of Labor, within 18 months, to promulgate a final occupational safety and health standard regulating combustible dust explosions that has the same scope and worker protection provisions as the interim rule and provides requirements for: (1) managing change of dust producing materials, technology, equipment, staffing, and procedures; (2) building design such as explosion venting, ducting, and sprinklers; and (3) explosion protection, including separation and segregation of the hazard. Requires the final rule to include relevant and appropriate provisions of the National Fire Protection Association combustible dust standards, including the Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids (NFPA 654), the Standard for Combustible Metals (NFPA 484), and the Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities (NFPA 61).

(Sec. 4) Requires the Secretary to revise the hazard communications standard to amend the definition of "physical hazard" to include "a combustible dust" as an additional example of such a hazard.

Requires such standard to provide requirements for: (1) a hazard assessment to identify, evaluate, and control combustible dust hazards; (2) a written program that includes provisions for hazardous dust inspection, testing, hot work, ignition control, and housekeeping, including the frequency and methods used to minimize accumulations of combustible dust on ledges, floors, equipment, and other exposed surfaces; (3) engineering (which requirements shall be effective six months after the date on which the interim standard is issued), administrative controls and operating procedures, such as means to control fugitive dust emissions and ignition sources, the safe use and maintenance of dust producing and dust collection systems and filters, minimizing horizontal surfaces where dust can accumulate, and sealing of areas inaccessible to housekeeping; (4) housekeeping to prevent accumulation of combustible dust in places of employment in depths that can present explosion, deflagration, or other fire hazards, including safe methods of dust removal; (5) employee participation in hazard assessment, development of and compliance with the written program, and other elements of hazard management; and (6) providing safety and health information and annual training to employees, including housekeeping procedures, hot work procedures, preventive maintenance procedures, common ignition sources, and lock-out, tag-out procedures.

Provides an exemption from otherwise applicable rulemaking requirements for the interim standard but not for the final standard.

Provides that such interim standard shall have the legal effect of an occupational safety and health standard and shall apply until a final standard becomes effective.

Requires the Secretary of Labor, within 18 months, to promulgate a final occupational safety and health standard regulating combustible dust explosions that has the same scope and worker protection provisions as the interim rule and provides requirements for: (1) managing change of dust producing materials, technology, equipment, staffing, and procedures; (2) building design such as explosion venting, ducting, and sprinklers; and (3) explosion protection, including separation and segregation of the hazard. Requires the final rule to include relevant and appropriate provisions of the National Fire Protection Association combustible dust standards.

(Sec. 4) Requires the Secretary to revise the hazard communications standard to amend the definition of "physical hazard" to include "a combustible dust" as an additional example of such a hazard.
