OSHA General Duty Clause

The OSHA General Duty Clause is the part of the Occupational Safety and Health Act that requires every covered employer to keep its workplace free of recognized serious hazards, even when no specific OSHA standard addresses them. It protects workers from dangers that the written standards do not cover, such as heat stress, workplace violence and many ergonomic hazards.

Because it fills the gaps between standards, the General Duty Clause is the reason compliance cannot stop at a checklist of OSHA rules. Employers are expected to identify and control serious hazards in their own operations, and OSHA uses the clause to cite employers that do not.

What Is the OSHA General Duty Clause?

The General Duty Clause is Section 5(a)(1) of the OSH Act, codified at 29 U.S.C. 654(a)(1). It is a statutory duty, not a regulation in the CFR. 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 his employees."

Section 5 contains two other duties that work alongside it:

• Section 5(a)(2) requires employers to comply with the occupational safety and health standards issued under the Act, such as those in 29 CFR 1910 and 1926.
• Section 5(b) requires each employee to comply with the standards, rules, regulations and orders that apply to their own actions and conduct.

The four elements of a violation

To cite an employer under the General Duty Clause, OSHA must prove four elements, as set out in its own letters of interpretation and enforcement memos:

1. The employer failed to keep the workplace free of a hazard to which its employees were exposed.
2. The hazard was recognized.
3. The hazard was causing or was likely to cause death or serious physical harm.
4. There was a feasible and useful method to correct the hazard.

A hazard can be recognized by the employer itself, for example through prior incidents, employee complaints, injury logs, safety data sheets or its own safety rules, or by the employer's industry, for example through trade association guidance, manufacturer warnings, consensus standards or government publications.

Who Must Comply?

The General Duty Clause applies to every employer covered by the OSH Act, which defines an employer as a person engaged in a business affecting commerce who has employees. There are no size or industry thresholds. The Act does not cover the United States government or states and their political subdivisions as employers, although public employees may be covered by an approved State Plan. Working conditions regulated by another federal agency that has exercised its authority over safety and health are also outside OSHA's reach under Section 4(b)(1).

State Plan states enforce their own programs, which must be at least as effective as federal OSHA's. Some states, such as California, Maryland, Nevada, Oregon, Washington and Minnesota, have adopted specific heat illness rules that apply in addition to any general duty obligation.

When the clause does not apply

OSHA uses the General Duty Clause only where no specific standard applies to the hazard. If a standard covers the hazard, OSHA cites the standard instead. For hazards no standard addresses, the clause is OSHA's main enforcement tool.

Key Requirements

The clause does not tell you exactly what to do. In practice, meeting it means running a program that finds and controls serious hazards:

Identify recognized hazards

Review your injury and illness records, incident and near miss reports, employee concerns, safety data sheets, manufacturer instructions and industry guidance. If your own documents or your industry treat something as dangerous, OSHA may treat it as a recognized hazard.

Assess severity and likelihood

The clause targets hazards that cause or are likely to cause death or serious physical harm. A structured risk assessment helps you rank hazards and document why you prioritized the controls you chose.

Apply feasible controls

Use the hierarchy of controls: eliminate or substitute the hazard where possible, then apply engineering controls, administrative controls and PPE. OSHA must show that a feasible means of abatement existed, so recognized industry practices are often the benchmark.

Common hazards addressed under the clause

• Heat. OSHA has no final heat standard. Its proposed Heat Injury and Illness Prevention rule, published August 30, 2024, had not been finalized as of an August 2026 Congressional Research Service update. OSHA enforces heat hazards through the General Duty Clause and a revised National Emphasis Program on heat issued April 10, 2026.
• Ergonomics. OSHA has stated in letters of interpretation that it has no specific ergonomics standard and that musculoskeletal hazards may be addressed under Section 5(a)(1).
• Workplace violence. OSHA has explained in letters of interpretation that where the risk of violence is significant enough to be a recognized hazard, employers are expected to take feasible steps to reduce it under the clause.
• Chemicals without exposure limits. OSHA's 2018 enforcement memo says a citation cannot rest only on exceeding a recommended limit; all four elements must be proven, and a hazard alert letter may be used instead.

Documentation and Ongoing Review

The General Duty Clause has no recordkeeping section of its own, but documentation is how you show a hazard was managed. Useful records include hazard assessments and job hazard analyses, written programs for specific risks, training records, inspection results, incident investigations and corrective action logs. Review assessments when processes, equipment, staffing or conditions change, after incidents, and on a regular schedule you set.

Common Violations and Penalties

• Ignoring your own warning signs. Prior injuries, near misses or complaints about the same hazard can establish recognition.
• Not following industry practice. If peers routinely use a control and you do not, OSHA may argue a feasible abatement method existed.
• Failing to act on manufacturer warnings. Instructions and safety data sheets can show a hazard was recognized.
• No program for seasonal or emerging hazards. Heat, for example, is a common gap.
• Relying on PPE alone. Higher-level controls are often feasible and expected.

Penalties for General Duty Clause citations follow OSHA's civil penalty structure. OSHA's 2026 penalty memo kept penalties at 2025 levels, with a maximum of $16,550 for a serious violation and $165,514 for a willful or repeated violation. See the OSHA penalties page for current figures. Where OSHA cannot establish all four elements, it may issue a hazard alert letter recommending controls instead of a citation.

How to Comply: Step by Step

1. Inventory your hazards. Walk every area and task, and include non-routine work, seasonal conditions and contractor activities.
2. Check which standards apply. Map each hazard to any specific OSHA standard. The rest are candidates for General Duty Clause exposure.
3. Gather evidence of recognition. Review incident history, complaints, SDSs, manufacturer manuals and industry guidance.
4. Assess and rank risk. Focus first on hazards that could cause death or serious physical harm.
5. Select feasible controls. Apply the hierarchy of controls and compare against recognized industry practice.
6. Write it down. Document assessments, decisions and controls in a written program where appropriate.
7. Train employees. Make sure workers understand the hazards and the controls, and know how to report concerns.
8. Verify and review. Inspect controls, investigate incidents, track corrective actions and update assessments when conditions change.

How SMS360 Helps

SMS360's Risk Assessment module gives teams a consistent way to identify hazards, rate their severity and likelihood, and record the controls chosen to reduce them. Assessments are stored in one place, so you can show how a hazard was evaluated and when it was last reviewed.

Corrective actions can be assigned and tracked to completion, digital forms and checklists support field assessments from mobile devices, and dashboards help leaders see where higher-risk hazards remain open. Together, these records help demonstrate that recognized hazards were identified and addressed.

Frequently Asked Questions

What does the OSHA General Duty Clause require?

Section 5(a)(1) of the OSH Act requires employers to provide a workplace free from recognized hazards that are causing or are likely to cause death or serious physical harm. It applies when no specific OSHA standard addresses the hazard. Employers meet it by identifying serious hazards and using feasible methods to control them.

When can OSHA cite the General Duty Clause?

OSHA can cite the clause when it can prove four elements: employees were exposed to a hazard, the hazard was recognized by the employer or its industry, it was causing or likely to cause death or serious physical harm, and a feasible means to correct it existed. If a specific standard applies, OSHA cites that standard instead.

Is heat stress covered by an OSHA standard?

Not yet at the federal level. OSHA proposed a heat injury and illness prevention standard in 2024, and it had not been finalized as of August 2026. OSHA currently addresses heat hazards through the General Duty Clause and its heat National Emphasis Program, and several State Plan states have their own heat rules.

What is a recognized hazard?

A recognized hazard is one that the employer or its industry knows about. Evidence can include the employer's own incident records, complaints, safety rules and safety data sheets, or industry sources such as trade association guidance, consensus standards and manufacturer warnings.
