Most workers in the U.S. private sector are covered by OSHA, but a few specific groups and situations fall outside OSHA’s coverage.

Core answer

The main groups that do not fall under OSHA coverage are:

  • Self‑employed individuals.
  • Immediate family members working on farms that employ only those family members.
  • Workers whose safety is regulated by another federal agency (for example, most mining, nuclear energy, many transportation workers, certain maritime roles).
  • Employees of state and local governments in states without an OSHA‑approved state plan (though many are covered by state plans instead).

Below is a more detailed, SEO‑friendly breakdown in blog style.

Which groups do not fall under OSHA coverage?

OSHA’s rules feel almost universal, but they do not apply to every worker or workplace in the United States. Understanding these gaps is important for employers, HR teams, and workers trying to figure out their rights and obligations in 2025.

Self‑employed and true independents

These are people who work only for themselves and have no employees.

  • Self‑employed individuals are not covered by the OSH Act.
  • Independent contractors who genuinely control how, when, and where they work are generally treated like self‑employed for OSHA purposes.
  • A business must have at least one employee (besides the owner themselves) to bring OSHA duties into play.

From a risk perspective, this means solo consultants, freelancers, or single‑person LLCs shoulder their own safety responsibilities rather than OSHA stepping in.

Family farms with only immediate family

Agriculture is a big exception that often surprises people.

  • Farms that employ only immediate members of the farmer’s family are not covered under the OSH Act.
  • These family‑only farms are explicitly exempt, even if they affect interstate commerce.
  • Once a farm hires any non‑family employee, OSHA requirements can apply, at least for those employees.

In practice, this creates a sharp line: a small family‑only farm operates outside OSHA, but bringing in seasonal or full‑time outside workers can trigger OSHA coverage.

Workers regulated by other federal agencies

Some industries are carved out because another federal body regulates workplace hazards.

  • Workers whose working conditions are regulated by other federal agencies are not covered by OSHA for those hazards.
  • This category includes most working conditions in:
    • Mining (covered by the Mine Safety and Health Administration, MSHA).
* Nuclear energy and nuclear weapons manufacturing (Department of Energy and related agencies).

* Many transportation sectors, such as parts of aviation (Federal Aviation Administration) and maritime work regulated by the Coast Guard.

The idea is to avoid overlapping rules: where another federal regulator has explicit safety authority, OSHA usually steps back.

State and local government employees

Public‑sector coverage depends heavily on where the worker is located.

  • Federal OSHA does not cover state and local government employees.
  • However, in states and territories that run OSHA‑approved “state plans,” those plans must cover public‑sector workers, so many state and local employees are protected under state OSHA equivalents.
  • In states without such a plan, those public employees fall outside OSHA and may rely on state‑level safety laws instead.

This split means two workers doing similar jobs in different states can have very different formal protections.

Volunteers, interns, and very small employers

Some groups sit at the edge of OSHA’s reach, with partial or situational coverage.

  • Volunteers are generally not covered, because there is no employer‑employee relationship, though exceptions can arise when volunteers are treated like employees under state or local law.
  • Unpaid interns and similar roles may fall outside OSHA if they are not legally employees; paid interns are more likely to be treated as covered employees.
  • Employers with 10 or fewer employees are not exempt from OSHA , but they often have partial exemptions from injury/illness recordkeeping, while still needing to comply with safety standards and report serious incidents.

This area is nuanced, and in practice, classification (volunteer vs. employee, contractor vs. employee) can drive whether OSHA applies.

Mini FAQ and current context

  • In 2025, OSHA’s basic coverage rules and exemptions are still grounded in the OSH Act language and Department of Labor guidance.
  • Many trending employment‑law questions now focus on:
    • Gig workers and platform‑based “contractors” and whether they should be reclassified as employees for OSHA and other protections.
* State‑level expansions of public‑sector safety protections where federal OSHA does not reach.

If a situation is borderline (for example, a “contractor” who looks and behaves like a regular employee), employment and labor regulators may treat the person as covered even if the contract label says otherwise.
