General Duty Clause

The General Duty Clause is Section 5(a)(1) of the Occupational Safety and Health Act of 1970. It requires every employer to provide each employee with employment and a place of employment that are free from recognized hazards that are causing or are likely to cause death or serious physical harm. OSHA uses it to cite serious hazards that no specific OSHA standard covers.

The clause matters because OSHA standards cannot anticipate every hazard. Even where no standard applies, such as many workplace violence, heat and ergonomic hazards, an employer can still be cited if it knew, or its industry knew, about a serious hazard and did not take feasible steps to control it.

What Is the General Duty Clause?

Section 5 of the OSH Act sets out the basic duties of employers and employees:

• Section 5(a)(1): the General Duty Clause, which covers recognized serious hazards.
• Section 5(a)(2): the duty to comply with occupational safety and health standards issued under the Act.
• Section 5(b): the duty of each employee to comply with standards, rules, regulations and orders that apply to their own actions and conduct.

The General Duty Clause is a gap filler. OSHA generally cannot use it when a specific standard already addresses the hazard, because in that case the standard is the correct basis for a citation.

The Four Elements OSHA Must Prove

To support a General Duty Clause citation, OSHA must show all of the following:

1. A hazard existed. The employer failed to keep the workplace free of a hazard to which its employees were exposed.
2. The hazard was recognized. The employer knew about it, or the hazard was recognized in the employer's industry. Recognition can come from industry consensus standards, manufacturer warnings, the employer's own safety rules, past incidents or common sense awareness.
3. The hazard was causing or likely to cause death or serious physical harm. Minor hazards do not qualify.
4. A feasible and useful means of abatement existed. There was a practical way to eliminate or materially reduce the hazard.

Because OSHA carries this burden of proof, General Duty Clause citations are less common than citations under specific standards, and they are typically reserved for serious hazards that are well documented.

Hazards Commonly Cited Under the Clause

OSHA has used the General Duty Clause for a wide range of hazards, including:

• Heat stress. There is no final federal heat standard. OSHA published a proposed heat injury and illness prevention rule in August 2024, but as of November 2026 it has not been finalized and its timing and final content remain uncertain. OSHA currently cites heat hazards under the General Duty Clause and targets them through its heat National Emphasis Program.
• Workplace violence. Particularly in healthcare, social services and late-night retail.
• Ergonomic hazards. Such as heavy lifting and repetitive work that cause musculoskeletal disorders. There is no federal ergonomics standard.
• Combustible dust. Where dust accumulations create fire or explosion hazards not fully covered by other standards.
• Other recognized hazards. Such as certain struck-by, vehicle and chemical reaction hazards where no specific standard applies.

How General Duty Clause Citations Work

A General Duty Clause violation is normally cited as serious, willful or repeat, since the clause only applies to hazards likely to cause death or serious physical harm. OSHA penalties are adjusted annually for inflation. Like any OSHA citation, it includes an abatement date and can be contested within 15 working days of receipt.

OSHA may also send a hazard alert letter instead of, or along with, a citation when it finds a hazard that does not meet all four elements but still warrants attention. These letters recommend specific actions and are not enforceable on their own, but they establish that the employer was told about the hazard.

How to Reduce General Duty Clause Exposure Step by Step

1. Identify hazards beyond the standards. Look for serious hazards that no specific OSHA standard addresses, using inspections, incident data and worker input.
2. Check industry recognition. Review consensus standards, trade association guidance, manufacturer instructions and NIOSH publications for your industry.
3. Assess severity. Focus first on hazards that could cause death or serious physical harm.
4. Apply feasible controls. Use the hierarchy of controls to eliminate or reduce each hazard.
5. Write it down. Document hazard assessments, programs, training and the controls you put in place.
6. Track follow-up. Assign corrective actions with owners and due dates, and verify completion.
7. Review after incidents and changes. Update assessments when incidents, near misses or process changes reveal new hazards.

Common Mistakes to Avoid

• Assuming that if no OSHA standard applies, there is no legal duty.
• Ignoring hazards the industry already recognizes, such as those in consensus standards or manufacturer warnings.
• Writing internal safety rules that identify a hazard and then not enforcing them, which can help show recognition.
• Failing to act on hazard alert letters, insurer recommendations or prior incidents.
• Keeping no records of hazard assessments or controls, which makes it hard to show what was done.

How SMS360 Helps

SMS360's Compliance Management module helps teams keep track of the obligations and programs that apply to each site. Hazards that fall outside specific standards can be assessed in Risk Assessment, and the controls that come out of them can be assigned, tracked and closed in Actions Management, creating a record of what was found and fixed.

Frequently Asked Questions

What does Section 5(a)(1) of the OSH Act say?

It says each employer shall furnish to each of its employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to its employees.

Can OSHA cite the General Duty Clause if a standard already applies?

Generally, no. When a specific standard addresses the hazard, OSHA should cite that standard. The General Duty Clause is used for recognized serious hazards that existing standards do not cover.

Does the General Duty Clause apply to heat?

Yes. Without a final federal heat standard, OSHA uses the General Duty Clause to cite serious heat hazards when it can prove all four elements. Several states with OSHA-approved State Plans have their own heat rules, which apply in those states.

What is a hazard alert letter?

It is a letter OSHA may send when it identifies a hazard but does not issue a General Duty Clause citation. It recommends corrective steps. It is not a citation, but ignoring it can make a later case easier for OSHA to prove.
