There are currently no standards for diesel exhaust as a unique hazard. However, exposures to various chemical components of diesel exhaust are addressed in specific standards for the
general industry and shipyard employment. This page 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.
OSHA
Section 5(a)(1) of the OSH Act, often referred to as the General Duty Clause, requires employers to "furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees". Section 5(a)(2) requires employers to "comply with occupational safety and health standards promulgated under this Act".

Note: Twenty-four states, Puerto Rico and the Virgin Islands have OSHA-approved State Plans and have adopted their own standards and enforcement policies. For the most part, these States adopt standards that are identical to Federal OSHA. However, some States have adopted different standards applicable to this topic or may have different enforcement policies.

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 regulations relating to the Clean Air Act and Air Toxics, including diesel exhaust emissions. Though these are not directly related to occupational exposure, lowering
emissions does lower potential occupational exposure.

EPA is finalizing nonconformance penalties (NCPs) for the 2004 and later model year non-methane hydrocarbons and nitrogen oxides (NMHC+NOx) standard for heavy-duty diesel engines and vehicles.
