There are twenty-eight OSHA-approved State Plans, operating state-wide occupational safety and health programs. State Plans are required to have standards and enforcement programs that are at least as effective as OSHA's and may have different or more stringent requirements.
OSHA has not established a standard for diesel exhaust as a unique hazard, however exposures to various components of diesel exhaust are addressed in specific standards for general industry and shipyard employment. This section highlights OSHA standards, Federal Registers (rules, proposed rules, and notices), directives (instructions for compliance officers), standard interpretations (official letters of interpretation of the standards), and other federal standards related to diesel exhaust.
General Industry (29 CFR 1910)
- 1910 Subpart N, Materials handling and storage
- 1910 Subpart Z, Toxic and hazardous substances [related topic page]
Shipyard Employment (29 CFR 1915)
- Powered Industrial Truck Operator Training; Final Rule. Final Rules 63:66237-66274, (1998, December 1). OSHA is revising its existing requirements for powered industrial truck operator training (codified at 29 CFR 1910.178(l)) and issuing new requirements to improve the training of these operators.

- Letter to Diesel Fuel Manufacturers. (1990, April 4). Provides diesel manufacturers with information regarding the Hazard Communication Standard's (HCS) requirement to include the hazards of diesel fuel exhaust on material safety data sheets (MSDS) for diesel fuel.
- Applicability of the HCS to diesel exhaust emissions and diesel fuel. (1988, December 22). States that the hazards of diesel exhaust must be included as part of the MSDS for diesel fuel.
- Hazardous components of diesel engine emissions. (1985, November 8). Discusses some potential health effects of diesel exhaust exposure.

Note: These are NOT OSHA regulations. However, they do provide guidance from their originating organizations related to worker protection.

Environmental Protection Agency (EPA)
The EPA is responsible for developing regulations that set emission standards for diesel vehicles and engines, as well as for diesel fuel. Though these are not directly related to occupational exposure, lowering emissions does lower potential occupational exposure.
