OSHA Standards
State Standards
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.
Exposures to 1,3-butadiene are addressed in specific standards for general industry. This section highlights OSHA standards, preambles to final rules (background to final rules), and letters of interpretation related to 1,3-butadiene.

Letters of Interpretation
- OSHA-recognized chemicals as carcinogens or potential carcinogens for Hazard Communication purposes. (October 16, 2003).
