OSHA: What It Means for Employers

What it means in practice

"OSHA" names the agency, but people also use it as shorthand for the law it enforces. Congress stated the Act's purpose as assuring "so far as possible every working man and woman in the Nation safe and healthful working conditions" (29 U.S.C. 651(b)). The Act also created the Occupational Safety and Health Review Commission, which decides contested citations, and the National Institute for Occupational Safety and Health (NIOSH), a research body (29 U.S.C. 652).

Who is covered. The Act defines an employer as a person engaged in a business affecting commerce "who has employees" (29 U.S.C. 652(5)). OSHA's coverage rule says any employer with one or more employees is covered, including professional practices, nonprofit and charitable organizations, and churches for their secular activities (29 CFR 1975.4). Agricultural employers are covered, but members of the farm employer's immediate family are not treated as employees. Because the definition turns on having employees, a self-employed person with no employees is not an employer under the Act. As a policy matter, individuals who privately employ household workers in their own homes for tasks like cleaning, cooking and child care are not subject to the Act for that employment (29 CFR 1975.6). The Act also does not apply to working conditions that another federal agency regulates under its own statutory authority (29 U.S.C. 653(b)(1)).

Public employers. States and their political subdivisions are not "employers" under the federal Act (29 CFR 1975.5), but a state that runs an approved state plan must cover its state and local government employees (29 U.S.C. 667(c)(6)). Federal agencies are covered differently: section 19 requires each agency head to maintain a safety and health program consistent with OSHA standards (29 U.S.C. 668; 29 CFR part 1960). The U.S. Postal Service is treated as an employer.

The general duty clause. Section 5(a)(1) requires each employer to furnish employment and a place of employment "free from recognized hazards that are causing or are likely to cause death or serious physical harm" to its employees. It reaches serious hazards that no specific standard addresses. Complying with a standard satisfies the general duty clause only for the condition that standard covers (29 CFR 1910.5(f)). Employees, in turn, must comply with the standards and rules that apply to their own conduct (29 U.S.C. 654(b)).

Standards. Section 5(a)(2) requires compliance with OSHA standards. General industry standards are in 29 CFR part 1910, which began by adopting existing national consensus and federal standards (29 CFR 1910.1). Construction standards are in 29 CFR part 1926 and apply to construction work, defined as construction, alteration or repair, including painting and decorating (29 CFR 1910.12). Where a specific standard applies to a condition it prevails over a general one, but general standards still apply where no specific standard does (29 CFR 1910.5(c)).

Employer responsibilities. Beyond the general duty and the standards, the regulations require employers to post the OSHA notice informing employees of their rights in each establishment, or an approved state poster in a state-plan state (29 CFR 1903.2); keep injury and illness records unless partially exempt (29 CFR part 1904); report severe injuries; set up a reasonable procedure for reporting work-related injuries and tell employees they have the right to report them without retaliation (29 CFR 1904.35); post any citation received; and correct cited hazards within the abatement period. Many employers describe the reporting procedure in the employee handbook, and the work usually sits with HR or a safety lead.

Worker rights. Employees or their representatives may request an inspection by giving written notice of a violation or imminent danger, and on request their names are withheld from the copy given to the employer (29 U.S.C. 657(f); 29 CFR 1903.11). An employee representative may accompany the inspector during the walkaround; a third party may do so if the inspector finds good cause (29 CFR 1903.8). Employees and former employees may access the injury and illness records (29 CFR 1904.35), and employees may challenge the abatement time set in a citation (29 CFR 1903.17(b)).

Refusing dangerous work. OSHA's regulation says there is generally no right to walk off the job over potential unsafe conditions (29 CFR 1977.12). But an employee who, with no reasonable alternative, refuses in good faith to face a condition a reasonable person would see as a real danger of death or serious injury is protected from retaliation, if there was not enough time to fix the danger through regular enforcement channels and, where possible, the employee asked the employer to correct it and it was not corrected.

Inspections. Compliance officers may enter workplaces at reasonable times, inspect conditions, review required records and question employers and employees privately (29 U.S.C. 657(a); 29 CFR 1903.3). Advance notice is generally prohibited, with exceptions such as apparent imminent danger, and is generally limited to 24 hours; unauthorized advance notice is a crime (29 CFR 1903.6; 29 U.S.C. 666(f)). If an employer refuses entry, OSHA may seek a warrant (29 CFR 1903.4). Inspections can follow employee complaints (29 CFR 1903.11) or severe injury reports, and the regulations treat imminent danger as the most urgent case: the inspector tells employees and the employer and recommends a court action to stop it (29 CFR 1903.13). At the end, the inspector holds a closing conference to discuss apparent violations (29 CFR 1903.7).

Citations. A citation must be in writing, describe the violation with particularity and set a reasonable time to correct it, and none may be issued more than six months after the violation (29 U.S.C. 658; 29 CFR 1903.14). Violations with no direct or immediate relationship to safety or health get a de minimis notice instead. The employer must post the citation at or near the place of the violation until it is corrected or for 3 working days, whichever is later (29 CFR 1903.16). An employer has 15 working days from receiving the penalty notice to contest; otherwise the citation and proposed penalty become a final order of the Review Commission (29 U.S.C. 659(a); 29 CFR 1903.17).

Penalty categories. Section 17 of the Act sets civil penalties for willful, repeated, serious and other-than-serious violations, for failure to correct a violation (per day), and for posting violations (29 U.S.C. 666). A violation is serious if there is a substantial probability that death or serious physical harm could result, unless the employer did not and could not with reasonable diligence know of it (29 U.S.C. 666(k)). Penalties reflect the size of the business, the gravity of the violation, good faith and history of violations (29 CFR 1903.15(b)). A willful violation that causes an employee's death can also bring criminal prosecution (29 U.S.C. 666(e)).

2026 penalty amounts. Under 29 CFR 1903.15(d), for penalties proposed after January 15, 2025: willful, at least $11,823 and up to $165,514 per violation; repeated, up to $165,514; serious and other-than-serious, up to $16,550 each; failure to correct, up to $16,550 per day; posting violations, up to $16,550. Normally they rise each January. On May 27, 2026, the Department of Labor published a notice that it was making no 2026 adjustment, because the October 2025 inflation data the law requires were not produced during the lapse in appropriations; it said it would review its penalties in 2027 (91 FR 31358).

Severe injury reporting. Every employer covered by the Act must report a work-related fatality within 8 hours and a work-related in-patient hospitalization, amputation or loss of an eye within 24 hours, even if it is exempt from keeping records (29 CFR 1904.1, 1904.39). Reports go by phone or in person to the nearest Area Office, by phone to 1-800-321-OSHA, or online. A fatality is reportable if it occurs within 30 days of the incident; a hospitalization, amputation or eye loss if it occurs within 24 hours. In-patient hospitalization means formal admission for care or treatment, not observation alone. Motor vehicle accidents on public roads are not reportable unless in a construction work zone.

Recordkeeping, briefly. Covered employers record work-related injuries and illnesses on OSHA forms. A company with 10 or fewer employees at all times during the last calendar year is partially exempt unless OSHA or the Bureau of Labor Statistics asks it in writing to keep records; size is measured by peak employment across the whole company (29 CFR 1904.1). Some low-hazard industries are also partially exempt (29 CFR 1904.2). Recording a case does not mean anyone was at fault or that the worker qualifies for workers' compensation (29 CFR 1904.0). For the forms and annual summary, see the OSHA 300A posting page.

State plans. Section 18 lets a state run its own program if its standards and enforcement are "at least as effective" as federal OSHA's; the plan must cover state and local government workers, and employers must still make reports to the Secretary of Labor (29 U.S.C. 667). Where a plan covers an issue, the state agency generally enforces it.

Example state: California. Cal/OSHA, the Division of Occupational Safety and Health, runs California's plan, which covers most private employers and state and local government (29 CFR 1952.7). California requires every employer to maintain a written Injury and Illness Prevention Program; employers with fewer than 10 employees may communicate some parts orally (8 CCR 3203). It also requires serious injuries, illnesses and deaths to be reported immediately, no later than 8 hours after the employer knows or should know, with up to 24 hours in exigent circumstances (8 CCR 342). That is stricter than the federal 24-hour window for hospitalizations. See California labor laws; other states differ.

Section 11(c) whistleblower protection. No person may discharge or discriminate against an employee for filing a safety complaint, starting or testifying in a proceeding, or exercising any right under the Act (29 U.S.C. 660(c)). Complaints go to OSHA within 30 days, and a pending grievance does not pause that period (29 CFR 1977.15). If OSHA finds a violation, the Secretary of Labor may sue in federal district court for relief including reinstatement with back pay; OSHA must notify the complainant of its determination within 90 days. See retaliation.

FAQ: Is OSHA the same as wage and hour law? No. Minimum wage and overtime come from the Fair Labor Standards Act, enforced by the Wage and Hour Division.

FAQ: Does the OSH Act replace workers' compensation? No. It does not supersede or affect any workers' compensation law (29 U.S.C. 653(b)(4)).

FAQ: Does a citation mean we broke the law? Not yet. Each citation must state that it is not a finding of violation unless it goes uncontested or the Review Commission affirms it (29 CFR 1903.14(e)).
