Primary legal sources for California

If you were hurt at a California oil or gas site, refinery or pipeline, California law generally makes workers' compensation the only remedy against your employer. A separate civil claim against someone else whose conduct played a part, such as an equipment maker or a site owner, is not taken away. Deadlines, fault rules and wrongful-death rules are set by California statutes.

Most people facing an oilfield or refinery injury in California arrive at this question in the middle of something hard: a hospital stay, missed paychecks, a supervisor's version of events that does not match what happened, or a phone call that a family member will not be coming home. You may already have a workers' compensation claim open and be wondering whether that is the whole story. This page walks through how California's own statutes treat these accidents, who besides an employer may answer for them, and which time limits the law sets.

If You Were Hurt on the Job: How California Divides Employer and Other Claims

California starts with one rule about employers. Under Labor Code section 3602, where the conditions of compensation set out in Section 3600 are met, the right to recover workers' compensation is "the sole and exclusive remedy of the employee or his or her dependents against the employer," except as specifically provided in section 3602 itself and in Sections 3706 and 4558. For a worker hurt on a California rig or in a refinery unit, that usually means the claim against the company that employs you runs through workers' compensation, with only the exceptions those sections name.

The second rule looks beyond the employer. Labor Code section 3852 provides that an employee's claim for compensation "does not affect their claim or right of action for all damages proximately resulting from the injury or death against any person other than the employer." In plain terms, filing for workers' compensation does not close the door on a civil case against someone else.

The third rule is the general duty of care. Civil Code section 1714, subdivision (a), says everyone is responsible not only for their willful acts but also for an injury caused to another by their "want of ordinary care or skill in the management of his or her property or person," except so far as the injured person, willfully or by want of ordinary care, brought the injury on themselves. A claim based on this duty, called negligence, asks whether someone owed a duty, failed it, and whether that failure caused the harm. Whether those pieces are present depends on the facts.

Put together, a hurt worker in California may have a workers' compensation claim, a civil claim against another party, or both. If you have only a workers' compensation claim open, the stakes lie in whether a second path exists that the compensation file never addresses. Which paths are open is often the first question in a conversation with an attorney.

What Kind of Accident Happened, and Why It Shapes the Claim

Oilfield and refinery injuries tend to fall into recognizable groups: equipment that fails under pressure or load, fires and explosions, falls from rigs, tanks or platforms, pipeline ruptures, and exposure to chemicals or gases. Each kind of accident can point toward different legal theories, depending on who owned, controlled or made the thing that caused the harm. For you, the type of accident can decide which parties are worth examining at all. An overview of how these cases work nationally is on the oilfield accident lawyer page.

Premises liability is a claim against someone who owns or controls a property for failing to use ordinary care in managing it, the duty Civil Code section 1714(a) describes. At a California well pad or refinery, the company that owns or runs the site is not always the worker's employer, which is why ownership and control of the area matter.

If a valve, hoist, pressure vessel, safety device or other equipment gave way, a product liability claim may reach those who designed, made or sold it, when a problem with the product is said to have caused your injury. The failure alone does not prove a defect, so what happened to the equipment afterward, and what evidence exists about it and how it was used, can matter to whether that claim holds up.

Pipeline work raises its own questions about operators, contractors and records, covered on the pipeline site accident page. Exposure to a hazardous material or toxic substance is treated separately because California sets a distinct timing rule for it, explained in the deadlines section below.

If several companies were working side by side when you were hurt, as is common at California sites, who directed the work at that moment can shape who may be a defendant. Sorting out those roles is part of what a conversation with an attorney can help with.

Who May Be Responsible Beyond Your Employer

The question many injured workers ask is whether anyone besides their employer can be held to account. Labor Code section 3852, quoted above, keeps a claim against "any person other than the employer" in place even when workers' compensation applies. That opens several categories worth looking at:

  • Manufacturers and sellers of equipment or products used at the site, through product liability.
  • Owners or operators of the property where the injury happened, through premises liability.
  • General contractors and subcontractors whose crews or decisions affected the work.
  • Other employers on a site where several companies work at once.

California divides responsibility among everyone whose fault contributed. In Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, the Supreme Court of California superseded the all-or-nothing rule of contributory negligence with a system of pure comparative negligence, which assigns liability in direct proportion to the amount of negligence of each of the parties. Comparative fault is that idea: blame is shared by percentage, and a worker's own share does not, by itself, end a claim.

A statute adds a rule about one kind of loss. Non-economic damages are losses that do not come with a bill or a pay stub, such as pain and suffering. Under Civil Code section 1431.2, subdivision (a), in any action for personal injury, property damage or wrongful death based on principles of comparative fault, "the liability of each defendant for non-economic damages shall be several only and shall not be joint." That means each defendant answers for its own share of those damages rather than for another defendant's share.

For a family or worker, these rules make it matter to identify every party whose role may be examined. Which roles are worth a closer look is something a conversation with an attorney can help clarify.

If Cal/OSHA Inspected the Site or Issued a Citation

If Cal/OSHA inspected your worksite or issued a citation after the accident, you may wonder whether that settles who is at fault. It does not, on its own. California's safety orders, citations and inspection information are published by the Department of Industrial Relations, which houses Cal/OSHA, at dir.ca.gov.

Labor Code section 6304.5 states the Legislature's intent that the provisions of that division, and the occupational safety and health standards and orders issued under the code, "are applicable to proceedings against employers for the exclusive purpose of maintaining and enforcing employee safety." That text speaks to proceedings against employers; how a safety order bears on a civil case against someone else is a separate question.

Evidence Code section 669 supplies one route. Its conditions include that a person violated a statute, ordinance or regulation of a public entity, and that the violation proximately caused death or injury to person or property; when the section's conditions are met, the failure to exercise due care is presumed. Lawyers often call this negligence per se, meaning carelessness the law presumes from breaking a safety rule rather than proving it from scratch.

A citation is an agency's action, not a court's finding of civil liability. Whether a particular order or citation matters in an injury case depends on what it covers, who it was issued to, and whether the violation caused the harm. For you, a citation may be a useful piece of the picture or may carry little weight, and reading it against the facts is something an attorney can help with.

Filing Deadlines That Apply to California Oilfield Injury Claims

A statute of limitations is the period the law allows for starting a lawsuit, and California's are set by statute. Under Code of Civil Procedure section 335.1, an action for "injury to, or for the death of, an individual caused by the wrongful act or neglect of another" must be brought within two years.

Exposure claims follow a different rule. Under Code of Civil Procedure section 340.8, subdivision (a), in a civil action for injury or illness based on exposure to a hazardous material or toxic substance, the action must be started no later than either two years from the date of injury, or two years after the plaintiff becomes aware of, or reasonably should have become aware of, an injury, the physical cause of the injury, and enough facts to put a reasonable person on inquiry notice that the injury was caused or contributed to by a wrongful act. Whether a given substance counts is a legal question in each case.

Age and capacity can pause the clock. Under Code of Civil Procedure section 352, subdivision (a), if a person entitled to bring an action covered by Chapter 3 (beginning with Section 335) was under the age of majority, or lacked the legal capacity to make decisions, when the cause of action accrued, that time is not counted. Section 352(b) provides that this section "shall not apply to an action against a public entity or public employee upon a cause of action for which a claim is required to be presented" under the Government Claims Act.

Claims against a government body add steps. Under Government Code section 945.4, except as provided in Sections 946.4 and 946.6, no suit for money or damages may be brought against a public entity on a claim that must be presented until a written claim has been presented and acted on by the board, or deemed rejected. Government Code section 911.2, subdivision (a), requires a claim relating to death or injury to person to be presented not later than six months after the cause of action accrues; a claim for any other cause of action, not later than one year. The suit itself must then be started within the time Government Code section 945.6, subdivision (a), sets: "not later than six months after the date such notice is personally delivered or deposited in the mail" if written notice is given in accordance with section 913, or, if it is not given, "within two years from the accrual of the cause of action."

A missed deadline can end a claim no matter its merits. Which of these periods governs depends on the injury, the defendant and when the claim accrued, and talking those details through with an attorney can help identify the rule that fits. That conversation starts with a request for a case evaluation.

If You Are Gathering Records After an Accident

The records that often matter include:

  • Incident reports and the employer's own accident reports.
  • Cal/OSHA inspection and citation records, published through the Department of Industrial Relations at dir.ca.gov.
  • Maintenance and inspection logs for the equipment involved.
  • Medical records and treatment history.
  • Photographs and video of the scene and the equipment.
  • Names and contact details of coworkers and other witnesses.
  • Manuals, labels, model and serial numbers, and other documentation for the product or equipment.

Each record can answer a different question in your case. Your medical records tie the injury to the event; maintenance logs and product documents speak to whether the equipment was cared for and how it was built; inspection records may show what a safety order required; and on a multi-employer site, work orders and contracts can show who controlled the area. Families sometimes find the clearest picture comes from several sources read together. A complete record can affect what a claim is able to show, while gaps can be hard to fill later, and an attorney can help identify which records bear on which party.

Wrongful Death Claims After a Fatal Oilfield Accident in California

When a worker does not survive a well blowout, a refinery fire or a pipeline accident, the family is left with grief and with questions they never expected to face. Wrongful death is a claim brought for a death caused by the wrongful act or neglect of another.

California names who may bring it. Under Code of Civil Procedure section 377.60, subdivision (a), the claim may be asserted by the decedent's surviving spouse, domestic partner, children and issue of deceased children, or, if there is no surviving issue, the persons, including the surviving spouse or domestic partner, who would be entitled to the decedent's property by intestate succession; the decedent's personal representative may also assert it on their behalf. The statute lists other persons in later subdivisions as well.

The two-year period in Code of Civil Procedure section 335.1, discussed above, covers actions for death as well as injury, and the comparative-fault rule from Li v. Yellow Cab Co. and Civil Code section 1431.2 apply to wrongful-death actions too. The public-entity claim rules also reach a cause of action for death.

The same exclusive-remedy and third-party rules matter here. Labor Code section 3602 refers to the remedy of an employee "or his or her dependents" against the employer, and section 3852 preserves a claim for damages from the "injury or death" against any person other than the employer. What a family may pursue, and against whom, depends on how the death happened and who played a part.

Frequently asked questions

Can a California oilfield worker sue someone other than their employer after a workplace injury?

Yes. Labor Code section 3852 provides that a workers' compensation claim does not affect a claim for damages from the injury or death against any person other than the employer. Whether such a claim exists depends on who else played a part and the facts.

How long does a worker have to file a personal injury claim after an oilfield accident in California?

Code of Civil Procedure section 335.1 sets two years for injury caused by the wrongful act or neglect of another. Exposure injuries fall under section 340.8, and claims against a public entity require a written claim first, presented within six months for injury under Government Code section 911.2(a).

What is the difference between a workers' compensation claim and a third-party lawsuit after an oilfield injury?

Workers' compensation is generally the exclusive remedy against the employer under Labor Code section 3602, subject to its listed exceptions. A third-party lawsuit is a separate civil claim, preserved by section 3852, against someone other than the employer, such as a manufacturer, site owner or contractor.

Who can bring a wrongful death claim after a fatal oilfield accident in California?

Under Code of Civil Procedure section 377.60(a), the surviving spouse, domestic partner, children and issue of deceased children may, or, with no surviving issue, those entitled by intestate succession, including a spouse or domestic partner. A personal representative may act for them. Section 335.1's two years applies.

Does a Cal/OSHA citation against an employer automatically mean the employer is liable in a civil lawsuit?

No. A citation is an agency action, not a civil finding. Under Labor Code section 6304.5, a citation, or the failure to issue one, is not admissible in a personal injury or wrongful death action "except as between an employee and his or her own employer," and Evidence Code section 669 presumes a lack of due care only when its conditions, including a violation that caused the injury, are met.

How does California's comparative fault rule work in an oilfield injury case?

Under Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, California uses pure comparative negligence, assigning liability in direct proportion to each party's negligence. Civil Code section 1431.2(a) makes each defendant's liability for non-economic damages, such as pain and suffering, several only and not joint.

Does the two-year deadline apply differently if the injury involved toxic exposure at a California oilfield?

It can. Code of Civil Procedure section 340.8(a) allows two years from the date of injury, or two years after the person becomes aware, or reasonably should have, of the injury, its physical cause and facts suggesting a wrongful act. Whether a substance qualifies depends on the case.

What if the injured worker was a minor at the time of the oilfield accident?

Under Code of Civil Procedure section 352(a), time while a person entitled to sue was under the age of majority, or lacked legal capacity, is not counted toward the limitation period. Section 352(b) provides that it "shall not apply to an action against a public entity or public employee upon a cause of action for which a claim is required to be presented."
