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.
This section highlights OSHA standards, preambles to final rules (background to final rules), directives (instructions for compliance officers), standard interpretations (official letters of interpretation of the standards), other federal standards, and national consensus standards related to process safety management (PSM).
Note: These are NOT OSHA regulations. However, they do provide guidance from their originating organizations related to worker protection.
