Abatement is the act of correcting a hazard that OSHA has cited. Every citation item lists an abatement date, the deadline by which the employer must eliminate the hazard or bring the condition into compliance. Under OSHA's abatement verification rule, the employer must then certify to OSHA, within 10 calendar days after the abatement date, that the violation has been corrected.
Abatement matters because it is the part of an OSHA inspection that actually protects workers. Paying a penalty does not close a citation; fixing the hazard and proving it was fixed does. Missing an abatement date can lead to a failure-to-abate notice with additional daily penalties, and poor abatement records make it hard to show OSHA, insurers or your own leadership that the problem is truly resolved.
What Is Abatement?
In OSHA terms, abatement means action by an employer to comply with a cited standard or regulation, or to eliminate a recognized hazard identified by OSHA during an inspection. It applies to violations of specific standards and to hazards cited under the General Duty Clause. The rules for proving abatement are in 29 CFR 1903.19, "Abatement verification."
The abatement period is the time OSHA allows between receipt of the citation and the abatement date. Short periods are common for simple fixes, such as replacing a missing guard. Longer periods may be set for engineering projects, equipment purchases or process changes.
Abatement Certification and Documentation
Certification (all cited items)
Within 10 calendar days after the abatement date, the employer must certify to OSHA that each cited violation has been abated. The certification must state the date and method of abatement for each item and confirm that affected employees and their representatives were informed. OSHA's rule includes a sample certification letter in its appendix.
There is one main exception. Certification is not required if the compliance officer observed the hazard being corrected during the on-site inspection, within 24 hours of identifying it, and the citation notes that abatement occurred.
Documentation (willful, repeat and some serious items)
For willful and repeat violations, and for serious violations when the citation says so, the employer must also submit documents proving abatement. Acceptable evidence includes purchase or repair receipts, photographs or video, and other written records showing the hazard was corrected.
Abatement plans and progress reports
When the abatement period for a serious, willful or repeat item exceeds 90 calendar days, OSHA may require an abatement plan, and the citation will say so. A required plan is due within 25 calendar days from the final order date and must describe the steps to be taken, a schedule and any interim measures to protect employees. OSHA may also require periodic progress reports on dates listed in the citation.
What every submission must include
- The employer's name and address
- The inspection number
- The citation and item numbers covered
- A statement that the information is accurate
- The signature of the employer or an authorized representative
Informing Employees and Tagging Equipment
Employees must be told about abatement. The employer posts a copy of each certification, plan or report (or a summary) near the place where the violation occurred, at or before the time it is submitted to OSHA. The document stays posted for three working days after submission. Employees and their representatives may also ask to review and copy abatement documents.
For serious, willful and repeat violations involving movable equipment, the employer must attach a warning tag or a copy of the citation to the equipment's operating controls or to the cited component. The tag stays on until the violation is abated and verified, the equipment is permanently removed from service, or the citation is vacated.
When You Need More Time: Petitions for Modification of Abatement
If an employer has made a good faith effort but cannot finish by the abatement date, it may file a Petition for Modification of Abatement (PMA) with the OSHA Area Director under 29 CFR 1903.14a. The petition is due no later than the end of the next working day after the original abatement date. It must explain the steps already taken, how much more time is needed and why, and the interim steps protecting employees.
The PMA must be posted where affected employees will see it for 10 working days, and employees or their representatives have 10 working days to object. A PMA is different from contesting the citation: a contest challenges the citation itself or the reasonableness of the abatement period, and must be filed within 15 working days of receiving the citation. When a citation is contested in good faith, the abatement period generally does not begin until the Review Commission issues a final order.
How to Abate a Citation Step by Step
- Read every item. List each citation item, its abatement date, and whether certification, documentation or a plan is required.
- Protect workers now. Put interim controls in place immediately, even if the permanent fix will take longer.
- Find the cause. Use root cause analysis so the fix addresses why the hazard existed, not just the symptom.
- Assign owners and dates. Turn each item into a corrective action with a named owner and a due date ahead of the OSHA deadline.
- Complete and verify the fix. Confirm the correction works in practice and check for the same hazard at other locations.
- Gather evidence. Collect photos, receipts, training records or written procedures as required for each item.
- Certify and post. Submit the certification within 10 calendar days of the abatement date and post copies for employees.
- Request time early if needed. File a PMA by the end of the next working day after the abatement date if the work cannot be finished.
Common Mistakes to Avoid
- Assuming that paying the penalty closes the citation.
- Forgetting the 10-calendar-day certification deadline after fixing the hazard.
- Abating only the exact spot cited while the same hazard exists elsewhere on site.
- Submitting certifications without the inspection number, item numbers or method of abatement.
- Not posting abatement documents or not tagging cited movable equipment.
- Waiting until after the abatement date has passed to ask for more time.

Frequently Asked Questions
How long do I have to certify abatement to OSHA?
The employer must certify abatement within 10 calendar days after the abatement date listed on the citation. Certification is not needed only when the compliance officer saw the hazard corrected during the inspection, within 24 hours, and the citation notes it.
What counts as abatement documentation?
Documentation is evidence that the hazard was fixed, such as purchase or repair receipts, photographs or video, and other written records. It is required for willful and repeat violations and for serious violations when the citation says so.
Can I get more time to abate a hazard?
Yes. If you have made a good faith effort but cannot finish, you can file a Petition for Modification of Abatement with the Area Director no later than the end of the next working day after the abatement date. The petition must be posted for employees for 10 working days.
What happens if I do not abate by the deadline?
OSHA can issue a failure-to-abate notice, with additional penalties that can accrue for each day the violation continues past the abatement date. OSHA's maximum penalty amounts are adjusted annually for inflation.
