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 methylene chloride are addressed in specific standards for general industry, shipyard employment and the construction industry. This section highlights OSHA standards, preambles to final rules (background to final rules), Federal Register notices (rules and proposed rules), directives (instruction to OSHA staff), and letters of interpretation (official letters of interpretation of the standards) related to methylene chloride.
