Cal/OSHA Serious Injury Reporting Requirements: Section 342

Under Cal/OSHA’s serious injury reporting requirements, a California employer must notify the Division of Occupational Safety and Health within eight hours of learning that a work-related incident caused a fatality, an inpatient hospitalization, an amputation, loss of an eye, or serious permanent disfigurement. The rule lives at Title 8, Section 342 of the California Code of Regulations, and the minimum civil penalty for missing it is $5,000.¹

What Counts as a Reportable Incident

Four categories of harm trigger the report, along with any workplace fatality:

Inpatient hospitalization for treatment. Any admission counts, no matter how brief. Hospitalization only for observation or diagnostic testing does not.
Amputation, meaning loss of any body part.
Loss of an eye.
Serious permanent disfigurement, going beyond a cosmetic issue.

The classification turns on the nature of the medical treatment, not the length of the stay. An employee admitted overnight for surgery on a crushed hand is reportable. An employee held a few hours for monitoring and released is not.²

Two Boundaries Worth Knowing

Injuries that happen on a public street or highway generally fall outside the reporting requirement. The exception is construction zones: an employee hurt while working in a construction zone on a public road is reportable like any other worksite injury.

Older versions of the law excluded injuries caused by the commission of a Penal Code violation. That exclusion is gone. A serious workplace injury is reportable even when criminal conduct contributed to it.²

The Eight-Hour Deadline

Section 342 defines “immediately” as no later than eight hours after you know or reasonably should have known about the incident.³ The clock starts when the information reaches any level of management. A shift supervisor who watches an employee leave in an ambulance has started the countdown, even if HR hears about it hours later.

If you can show that “exigent circumstances” made reporting within eight hours physically impossible, the deadline extends to 24 hours. A regional loss of phone and internet after a natural disaster is the kind of situation the regulation contemplates. Internal bureaucracy is not. Waiting for corporate headquarters to review the facts, or routing the report through legal counsel first, will not excuse a late filing.³

How to Submit the Report

Cal/OSHA prefers a phone call. Each regional and district office publishes its own number on the Cal/OSHA website, and the agency asks employers to call the nearest office around the clock.⁴

If you cannot reach someone by phone, email is the backup. Cal/OSHA maintains a dedicated email address for accident reports, and the same information required for a phone report has to appear in the body of the message.⁵ Labor Code 6409.1 anticipates a future online reporting system, but that portal is not yet available.¹

Write down the name of the Cal/OSHA representative who took your report, along with the exact date and time. Save the sent copy if you emailed. This is your proof of timely compliance if the agency later challenges whether you met the deadline.

The Ten Items You Must Provide

Section 342 lists ten specific data points that should accompany every report, to the extent they are available:

Time and date of the incident.
The employer’s name, address, and phone number.
Name and job title, or badge number, of the person making the report.
Address of the accident site.
An on-site contact person at that location.
Name and address of the injured employee.
Nature of the injury (for example, crush injury to the left hand, third-degree burns to the forearm).
Where the employee was taken for treatment.
Other agencies on scene, such as police or fire.
A description of the accident, including whether the scene or equipment has been moved or altered.³

That last item catches employers off guard. Cal/OSHA wants to know immediately whether the accident scene is still intact, because inspectors may need to examine it. If equipment has been repositioned or debris cleared, say so honestly.

Most of the information should already be in your internal incident report or personnel files. A pre-built checklist at each worksite, with the employer’s legal name, address, and the nearest Cal/OSHA district office number filled in ahead of time, saves you from scrambling while the eight-hour clock runs.

Penalties for Failing to Report

The consequences come in two forms, and they can stack.

Civil Penalties

An employer who fails to report a serious injury or illness faces a civil penalty of no less than $5,000.¹ That is the floor. The maximum civil penalty for a serious violation under Cal/OSHA is $25,000. These amounts are adjusted periodically, so the actual assessment in any case depends on severity, the employer’s history, and other factors.

Criminal Penalties

Knowingly failing to report a workplace death is a misdemeanor. An individual faces up to one year in county jail, a fine of up to $15,000, or both. For a corporation or LLC, the maximum fine rises to $150,000.⁶

Knowingly or negligently committing a serious safety violation carries up to six months in jail, a fine of up to $5,000, or both. Repeated violations that create a real and apparent hazard raise the ceiling to one year in jail and fines of up to $15,000 for individuals or $150,000 for corporations.⁶

What Happens After You Report

Filing is the start of the process. Cal/OSHA will typically assign an inspector, who arrives with a State of California ID card and holds an opening conference with an employer representative, and with an employee representative if one is available. The inspector then walks the site, takes photographs, and conducts confidential interviews with employees, managers, the injured worker if possible, and any witnesses.⁷

Expect requests for written safety programs, training records, and your OSHA 300 injury and illness logs. Some investigations wrap in a single visit; others involve several follow-ups. Before leaving, the inspector shares preliminary findings about any hazards observed.

Cal/OSHA must issue any resulting citations within six months of when the violation occurred or the date of the serious injury.⁷ If the agency plans to classify a violation as “serious,” it must first send you a Notice of Intent (the 1BY notice) at least 15 calendar days before issuing the citation. That notice describes the alleged violation and invites you to explain why a serious classification is not warranted.⁸
