Federal OSHA jurisdiction
Delaware does not operate an OSHA-approved State Plan. Federal OSHA administers and enforces occupational safety and health standards for most private sector employers and workers in the state. State and local government workers are not covered by federal OSHA and have no enforceable state workplace safety and health program.

Workers' compensation insurance requirement
Delaware requires every employer with one or more employees to carry workers' compensation insurance or qualify as a self-insurer. Farm laborers are excluded from mandatory coverage, though farm employers may elect to provide it. The insurance requirement is compulsory under 19 Del. C. § 2306, and employers must insure their liability for compensation under § 2372 through an authorized insurance carrier or by demonstrating financial ability to self-insure.
