How does the OSH Act define an employer?

As “a person engaged in a business affecting commerce who has employees,” excluding the U.S. government and states/political subdivisions (OSH Act §3(5)). The employer holds OSHA's primary compliance duties.

Is a self-employed person an employer under OSHA?

Generally no — a self-employed individual with no employees isn't a covered employer. Once they hire employees, they become an employer with OSHA duties.

Are government agencies covered as employers?

The federal government and state/local governments aren't “employers” under §3(5) of federal OSHA. Federal agencies and (in state-plan states) public employees are covered through separate provisions.

Employer

Verified vs OSHA sources · 2026-10-05

Under the OSH Act (Section 3(5)), an employer is “a person engaged in a business affecting commerce who has employees,” excluding the federal government and states/political subdivisions. The employer is the party that carries OSHA's core duties — complying with all applicable standards and the General Duty Clause, and keeping the workplace free of recognized hazards. Self-employed individuals with no employees are generally not covered.

Also known as: covered employer, OSH Act employer

Employer at a glance

Defined in OSH Act §3(5): a person in a business affecting commerce who has employees.
The employer holds the primary duty to comply with OSHA standards and the General Duty Clause.
Excluded: the federal government and state/local governments (covered separately, e.g., by state plans); self-employed persons with no employees.
On multi-employer worksites, one company can hold several roles (creating, exposing, correcting, controlling employer).

In plain English

In OSHA's world, an employer is basically any business that has employees. That business is the one legally on the hook to follow safety standards and keep the workplace free of serious hazards.

What the source says, in summary

The term “employer” means a person engaged in a business affecting commerce who has employees, but does not include the United States ... or any State or political subdivision of a State.

In context

An enforcement, recordkeeping, or general-duty concept under the Occupational Safety and Health Act and 29 CFR. These terms define how OSHA inspects, cites, and penalizes employers.

Example

A 12-person HVAC contractor is an “employer” under §3(5) and must comply with the applicable 1926 construction standards for its crew. A truly self-employed sole proprietor with no employees generally isn't a covered employer — but the moment they hire someone, OSHA duties attach.

Why it matters

The definition sets who OSHA can cite and who owes the duties. Most private-sector businesses with employees are covered, so understanding employer status — and the multi-employer roles that layer on top at shared worksites — determines who is responsible when a hazard exists.

Employer status vs. multi-employer roles

Being “an employer” under §3(5) is the baseline. On a shared jobsite, OSHA's multi-employer policy can additionally make a company a controlling, creating, exposing, or correcting employer for a given hazard — roles that can extend responsibility beyond just your own employees. Employer status is the entry point; the multi-employer roles refine who's liable.

Covered vs. not covered under the OSH Act

Party	Covered as an employer?
Private business with employees	Yes
Self-employed, no employees	Generally no
Federal government	No (covered under separate provisions)
State/local government	No under federal OSHA (may be under a state plan)

Abatement

The action an employer takes to fix a cited violation or eliminate a hazard OSHA identified during an inspection. The citation sets an abatement date, the deadline to correct the hazard, and within 10 calendar days after that date the employer must certify to OSHA that the violation was abated. Failure to abate accrues additional penalties of up to $16,550 per day.

Area Director

The senior OSHA official in charge of a specific OSHA Area Office — the local unit that runs inspections and enforcement in its geographic territory. The Area Director has the authority to issue citations, propose penalties, hold informal conferences with employers, and approve settlement agreements. When a Compliance Safety and Health Officer (CSHO) completes an inspection, it's the Area Director who ultimately issues the citation.

Bureau of Labor Statistics (BLS)

The federal statistical agency within the U.S. Department of Labor that collects, analyzes, and publishes data on workplace injuries, illnesses, and fatalities. BLS conducts the annual Survey of Occupational Injuries and Illnesses (SOII) — compiled from employer OSHA 300 logs — and the Census of Fatal Occupational Injuries (CFOI). SOII data drives OSHA's Site-Specific Targeting (SST) program: establishments whose DART rates significantly exceed their BLS industry average are placed on the SST inspection list.

Competent Person

Under OSHA's construction standards, a person who is capable of identifying existing and predictable hazards in the surroundings or working conditions, and who has the authorization to take prompt corrective measures to eliminate them. The role requires both knowledge and the authority to act, and is mandated by name in many specific standards — excavations, scaffolds, fall protection, asbestos, and more.

Citation

The formal written notice OSHA issues to an employer after an inspection, describing each alleged violation, the standard cited, the proposed penalty, and the date by which the hazard must be corrected (abated). OSHA must issue a citation with reasonable promptness and no later than six months after the violation occurred.

Closing Conference

The meeting at the end of an OSHA inspection where the compliance officer confers with the employer and informally advises them of any apparent violations found. Importantly, the closing conference discusses what was observed and the employer's rights — but it does NOT state final citations or penalties, which come later in the written Citation and Notification of Penalty.

Compliance Officer (CSHO)

An OSHA Compliance Safety and Health Officer — the inspector who conducts workplace inspections. A CSHO presents credentials (a photo ID and a serial number), holds the opening conference, performs the walkaround, collects evidence, interviews employees, and recommends citations. CSHOs are either safety specialists or industrial hygienists.

Contest

An employer's formal challenge to an OSHA citation, penalty, or abatement date. To contest, the employer must file a written Notice of Contest with the OSHA Area Director within 15 working days of receiving the Citation and Notification of Penalty. Filing sends the case to the independent Occupational Safety and Health Review Commission (OSHRC); missing the deadline makes the citation a final, un-appealable order.
