A Cal/OSHA citation becomes a final order if the employer doesn’t appeal it to the Occupational Safety and Health Appeals Board within 15 working days of receiving it. A call or letter to Cal/OSHA itself doesn’t count as an appeal. A timely appeal can contest whether the violation happened, how it’s classified, the abatement terms, and the penalty. A serious classification can be rebutted with proof the employer couldn’t reasonably have known about the hazard and fixed it once it did.
How long does an employer have to appeal?
Fifteen working days from receipt. Labor Code section 6600 lets an employer served with a citation or notice of proposed penalty “appeal to the appeals board within 15 working days from the receipt of such citation or such notice,” and the appeal can address the violations alleged, abatement periods, proposed penalties, and the changes Cal/OSHA requires.
Missing the window is costly. Under section 6601, an unappealed citation or penalty notice “shall be deemed a final order of the appeals board and not subject to review by any court or agency.” A final citation can also support a later repeat classification. Under 8 CCR section 361.3(e), when a new citation is classified as a repeat, “the earlier citation established by failure to appeal or the entry of a final disposition by the Appeals Board shall not be in issue” in the later appeal. An employer that pays a small penalty to make it go away may be building a record against itself.
The appeal is filed with the Appeals Board, not the agency that issued the citation. Under 8 CCR section 359(c), “A communication to the Division of Occupational Safety & Health indicating an intent to appeal is not an intent to file an appeal.” An employer can notify the Appeals Board by telephone, in writing, in person at its main office, or online through its OASIS system, according to subsection (b).
What if the deadline has already passed?
A late appeal needs good cause. Section 359(d) allows a late filing “upon a written showing of good cause that contains sufficient facts to show or establish a reasonable basis for the late filing,” and subsection (e) requires a declaration based on personal knowledge. A citation that sat in someone’s inbox is a weak reason. A showing tied to specific facts, like a mailing problem or a sudden illness, stands a better chance.
Talking with Cal/OSHA doesn’t stop the clock. Subsection (i) says “Negotiations that do not result in an executed settlement agreement are not good cause for a late appeal under subsection (g).” Subsection (g) does let the Board find good cause where the parties actually reached a settlement within three months of the citation and pursued it before the late appeal. Employers shouldn’t rely on that. The safer course is to file the appeal and keep talking.
What can an appeal challenge?
Only what the employer puts in it. Under 8 CCR section 361.3, “The issues on appeal shall be limited to those arising out of the facts set forth in the Division action, and the grounds set forth in the appeal.” For each citation and item, the employer has to identify the components it’s challenging.
Affirmative defenses also have to be raised. Section 361.3(b) says “An affirmative defense must be timely raised by appellant,” and lists examples, including independent employee action, compliance with a different safety order that applied, an exception in Title 8, and an invalid inspection. A defense that isn’t in the appeal may be lost.
| What the appeal can contest | What the employer usually argues | Source |
|---|---|---|
| Existence of the violation | The cited standard didn’t apply, or the facts don’t show a violation | 8 CCR § 361.3(a)(1) |
| Classification | The violation was misclassified | 8 CCR § 361.3(a)(2); Lab. Code § 6432 |
| Abatement period and required changes | The deadline or the fix Cal/OSHA demands is unreasonable | 8 CCR § 361.3(a)(3)–(4) |
| Proposed penalty | The penalty factors weren’t applied correctly | 8 CCR § 361.3(a)(5); Lab. Code § 6319(c) |
A penalty-only appeal is narrower than it looks. Under section 361.3(c), if the appeal contests only the penalty, the issues are limited to the classification and the reasonableness of the penalty. The existence of the violation is off the table.
How can an employer rebut a serious classification?
By showing it couldn’t have known. Labor Code section 6432(a) creates a rebuttable presumption of a serious violation when Cal/OSHA shows “there is a realistic possibility that death or serious physical harm could result from the actual hazard created by the violation.” Under subdivision (c), “the employer may rebut the presumption and establish that a violation is not serious by demonstrating that the employer did not know and could not, with the exercise of reasonable diligence, have known of the presence of the violation.”
The statute spells out how. The employer shows it took the steps a reasonable and responsible employer would take, before the violation, to anticipate and prevent it, and that it took effective action to eliminate exposure “as soon as the violation was discovered,” according to section 6432(c). Training records and inspection logs are usually the core evidence for this defense.
The process starts before the citation issues. Before citing a violation as serious, Cal/OSHA must make a reasonable attempt to learn the employer’s side, and section 6432(b)(2) lets it meet that duty by delivering a standardized form, at least 15 days before the citation, describing the violations it intends to cite as serious. Under subdivision (d), an employer that doesn’t respond isn’t barred from presenting the information at the hearing, and “no negative inference shall be drawn.” But the trier of fact “may draw a negative inference from the prior inconsistent factual information.” A rushed response to that form can do more harm than silence, so it deserves the same care as the appeal.
How are penalties set, and can they be reduced?
By statutory factors. Section 6319(c) directs the penalty regulations to give due consideration to the size of the business, the gravity of the violation, the employer’s good faith including timely abatement, and its history of previous violations. An appeal can argue that Cal/OSHA applied those factors wrong.
Some penalties can’t be reduced much. Under subdivision (d), when serious injury, illness, exposure, or death is caused by a serious, willful, or repeated violation, or by a failure to correct a serious violation in time, “the penalty shall not be reduced for a reason other than the size of the business of the employer being charged.” In those cases, the classification fight usually matters more than the penalty math.
What happens after the hearing?
The Board decides, and further review is short and narrow. Under section 6602, the Appeals Board issues “a decision, based on findings of fact, affirming, modifying, or vacating the division’s citation, order, or proposed penalty, or directing other appropriate relief.” A party can petition for reconsideration within 30 days of a final order or decision under section 6614. After that, section 6627 allows a writ of mandate in superior court within 30 days after reconsideration is denied or decided.
Multi-site employers face one more issue. Under section 6317(b), “there shall be a rebuttable presumption that a violation is enterprise-wide” when the employer has a written policy that violates a standard, or Cal/OSHA has evidence of a pattern of the same violation at more than one worksite. If the presumption isn’t rebutted, Cal/OSHA may require abatement across the whole company. A written policy that’s out of date can turn a single-site citation into a company-wide one.
What about the employee who reported the hazard?
Leave that employee alone. Section 6310(a) says “No person shall discharge or in any manner discriminate against any employee because the employee has done any of the following,” and the list includes making an oral or written complaint to Cal/OSHA or to the employer. Discipline that follows an inspection, even for an unrelated reason, invites a retaliation claim. The firm’s post on Labor Code section 98.6 retaliation claims covers how those complaints are handled.
When a Cal/OSHA citation arrives
- Preserve the inspection documents, the citation and envelope showing the receipt date, training and safety meeting records, inspection logs, the injury and illness prevention program and other written procedures in effect, and the emails and texts about the cited condition.
- Calendar the 15-working-day appeal deadline from the date of receipt and the abatement dates in the citation, and check for an employment practices liability (EPLI) or other insurance policy with notice terms.
- Identify the supervisors and employees who were present during the inspection or know the cited condition, and stop any action against an employee who complained or spoke with the inspector that could look like retaliation.
- Pull the records showing what the company did to anticipate and prevent the hazard, and what it did once the hazard was found, including proof of abatement.
- Get legal advice before responding to the pre-citation form, filing the appeal, or negotiating a settlement with Cal/OSHA.
The appeal is the only way to keep the defenses open. The firm’s page on employer defense in California employment cases covers related agency proceedings.
Cal/OSHA appeal questions employers ask
Does telling the inspector we disagree count as an appeal?
No. 8 CCR section 359(c) says a communication to the Division indicating an intent to appeal isn’t an intent to file an appeal. The notice has to go to the Appeals Board within 15 working days of receipt. Disagreeing with the inspector during the closing conference can help frame the issues, but it doesn’t preserve them.
Can we appeal only the penalty and fix the hazard?
Yes. But under section 361.3(c), a penalty-only appeal limits the issues to the classification and the reasonableness of the penalty. The employer gives up any argument that the violation didn’t happen. That matters if the citation could later support a repeat classification.
Do we have to answer Cal/OSHA’s pre-citation serious-violation form?
No. Under section 6432(d), an employer that doesn’t respond can still present the information at the hearing, with no negative inference. But a response can head off a serious classification before it’s issued, and an inaccurate one can be used against the company. The answer should be reviewed with the same care as the appeal.
What if we settled with Cal/OSHA but missed the appeal deadline?
Section 359(g) lets the Appeals Board find good cause for a late appeal when a settlement was reached within three months of the citation and the parties actively pursued it before the late filing. Negotiations that don’t end in an executed settlement agreement don’t qualify. Filing the appeal on time and negotiating afterward avoids the problem.
