What Are the Types of OSHA Violations?

Every year, OSHA conducts tens of thousands of workplace inspections, and citations follow when inspectors find conditions that fall short of federal safety standards. The penalties attached to those citations vary widely depending on the nature and severity of the violation, ranging from informal notes in a case file all the way to six-figure fines per instance.

Understanding how OSHA classifies violations is not just a compliance exercise. It shapes how your organization prioritizes hazard correction, prepares for inspections, and budgets for potential exposure. Below is a breakdown of all six OSHA violation types, their current penalty amounts, and practical steps for responding to a citation.

How OSHA Penalty Amounts Are Set

Before diving into individual violation types, it helps to understand how OSHA arrives at penalty figures. The agency adjusts its maximum civil penalties each year for inflation under the Federal Civil Penalties Inflation Adjustment Act of 2015. The amounts below reflect the current maximums effective after January 15, 2026 (source: osha.gov/penalties).

Actual assessed penalties are calculated using OSHA's Gravity Based Penalty (GBP) system, which accounts for the severity of the hazard, the number of workers exposed, the employer's size, compliance history, and good faith efforts to maintain a safe workplace. Small employers can qualify for reductions of up to 70%, and employers with clean inspection histories may receive an additional 20% reduction. None of these reductions apply to willful violations.

The Six Types of OSHA Violations

De Minimis Violations

De minimis violations are the least consequential category. They carry no monetary penalty because they do not directly affect worker health or safety. A de minimis citation means the employer implemented a safety measure that differs from the specific method described in an OSHA standard but still provides equivalent protection.

An inspector will document a de minimis finding in the case file and notify the employer, but no formal citation or abatement requirement is issued. These violations do not appear on the employer's public inspection record.

Other-Than-Serious Violations

An other-than-serious violation involves a condition that has a direct relationship to workplace safety or health but is unlikely to cause death or serious physical harm. Common examples include incomplete OSHA 300 logs, failure to post required workplace safety notices, or minor recordkeeping gaps.

Maximum penalty: $16,550 per violation

Inspectors have significant discretion with other-than-serious citations. A first-time violation with a cooperative employer may result in a reduced fine or, in some cases, no monetary penalty at all. However, the same violation found on a repeat inspection will be treated far more seriously.

Serious Violations

A violation is classified as serious when there is a substantial probability that death or serious physical harm could result from the hazardous condition, and the employer knew or should have known about the hazard. This is the most commonly issued citation category during OSHA inspections.

Maximum penalty: $16,550 per violation

The key distinction from other-than-serious violations is the severity of the potential outcome. A missing machine guard on a press, inadequate fall protection on a scaffold, or failure to implement a lockout/tagout program would all typically be classified as serious. The GBP system assigns penalty amounts based on severity (high, moderate, or low gravity), and reductions for employer size, good faith, and history are applied from there.

Willful Violations

Willful violations represent the most severe classification OSHA can issue. A willful citation means the employer was aware of the hazardous condition and the applicable OSHA standard but intentionally chose not to comply, or acted with plain indifference to the safety requirement.

Maximum penalty: $165,514 per violation (minimum: $11,524)

Unlike other violation types, willful citations carry a mandatory minimum penalty, and no reductions are granted for employer size or good faith. Employers who receive willful citations are also placed into OSHA's Severe Violator Enforcement Program (SVEP), which triggers mandatory follow-up inspections at the cited establishment and can extend enhanced scrutiny to the employer's other worksites.

Criminal exposure: Under 29 U.S.C. Section 666(e), if a willful violation results in the death of an employee, the employer can face criminal prosecution. A first offense carries a fine of up to $10,000 and imprisonment of up to six months. A conviction for a subsequent offense doubles those maximums to $20,000 and one year. It is worth noting that some states with their own OSHA-approved plans impose significantly higher criminal penalties. California, for example, allows fines up to $250,000 for individuals and $1,500,000 for corporations under Labor Code Section 6425.

Repeated Violations

A repeated violation occurs when OSHA finds a substantially similar violation to one the employer was previously cited for within the past five years. The employer does not need to have committed the exact same violation at the exact same location. If the hazard is substantially similar in nature, it qualifies.

Maximum penalty: $165,514 per violation

Repeated citations carry the same maximum as willful violations and also trigger SVEP enrollment. However, there is an important procedural safeguard: the original citation must be a final order before a new violation can be classified as repeated. If an employer has contested the original citation and is still awaiting a decision from the Occupational Safety and Health Review Commission, a subsequent finding of the same condition cannot be classified as a repeat.

Failure to Abate Violations

When an employer receives a citation, OSHA sets a deadline by which the hazard must be corrected. A failure to abate violation is issued when the employer does not correct the cited condition within that abatement period.

Maximum penalty: $16,550 per day beyond the abatement date

This penalty structure is designed to create escalating financial pressure that discourages employers from delaying corrections. A hazard that remains uncorrected for 30 days beyond the abatement deadline can generate nearly $500,000 in penalties from the failure to abate citation alone, on top of the original citation penalty.

What to Do If You Receive a Citation

Employers have 15 working days from receipt of a citation to take action. During that window, there are two primary options.

Request an informal conference. Employers can meet with the OSHA Area Director to discuss the facts of the citation, present evidence of corrective actions already taken, and negotiate adjustments to penalty amounts, abatement timelines, or violation classifications. Organizations that come prepared with documented corrective actions and supporting evidence routinely achieve penalty reductions of 30% to 50%.

File a formal contest. If the employer disagrees with the citation, the penalty, or the abatement period, they can file a notice of contest within the 15-working-day window. This initiates a formal review by the Occupational Safety and Health Review Commission. Uncontested citations become final orders and cannot be challenged later.

Regardless of whether a citation is contested, employers are required to post the citation at or near the location of the violation for three working days or until the hazard is corrected, whichever is longer.

State Plans and Additional Penalties

Twenty-two states and several U.S. territories operate their own OSHA-approved State Plans. These programs are required to maintain standards and enforcement that are at least as effective as the federal program, but many exceed federal penalty levels. California, Oregon, Washington, and several other states impose higher maximum fines and, in some cases, broader criminal liability for safety violations. Employers operating in multiple states should be aware of the specific enforcement landscape in each jurisdiction.

Building a Proactive Compliance Program

OSHA violations at any level represent both a financial risk and a signal that your safety management processes have gaps. The cost of a citation extends well beyond the penalty itself when you factor in abatement expenses, increased insurance premiums, potential litigation, and reputational impact.

Organizations that invest in proactive compliance programs, including regular self-audits, thorough incident investigation, documented training, and centralized hazard tracking, consistently see lower citation rates and better outcomes when inspections do occur. Compliance management software helps teams stay ahead of regulatory deadlines, track corrective actions to completion, and maintain the documentation that demonstrates good faith during an inspection.
