OSHA jurisdiction — federal coverage for private sector
Alabama does not operate an OSHA-approved state plan. Private-sector employers and workers in Alabama are subject to federal OSHA jurisdiction under 29 U.S.C. § 651 et seq. (the Occupational Safety and Health Act). State and local government workers are not covered by federal OSHA and have no OSH Act protections in Alabama. Federal OSHA enforces workplace safety and health standards through two area offices in Alabama, located in Birmingham and Mobile.

OSHA poster requirement — "Job Safety and Health: It's the Law"
Private-sector employers in Alabama must post the federal OSHA "Job Safety and Health: It's the Law" poster in a conspicuous place where employees can see it (typically where notices to employees are customarily posted). The poster informs workers of their rights under the Occupational Safety and Health Act, including the right to a safe workplace, to report hazards without retaliation, and to request an OSHA inspection. Because Alabama does not operate an OSHA-approved state plan, employers use the federal poster, not a state equivalent. Reproductions or facsimiles are permitted if they are not less than 8½ × 14 inches with type not less than 10 points. OSHA provides the poster free of charge at osha.gov/publications/poster.
