Refinery Explosion Lawyer: What Workers and Families Need to Know

Key Takeaways

A refinery explosion case usually turns less on the blast itself than on the paperwork and control lines that existed before it.

• Refineries are governed by federal process safety rules. The process safety management standard, 29 C.F.R. § 1910.119, applies to processes involving highly hazardous chemicals at or above listed threshold quantities, and to certain flammable liquids and gases in the quantities it states.
• Each employer the Occupational Safety and Health Act covers has a general duty under 29 U.S.C. § 654(a) to keep its workplace free from recognized hazards likely to cause death or serious physical harm.
• A refinery often holds several employers at once. The owner or operator, contractors, a maintenance company and equipment makers each have roles the law treats differently, and that separation is often where a civil claim lives.
• The U.S. Chemical Safety and Hazard Investigation Board investigates root causes and issues safety recommendations. It does not fine anyone or decide fault, but its public work can still shed light on what happened.
• Limitation periods, fault rules, damages rules and workers' compensation rules all differ by state.
• A safety standard or an investigation report does not, on its own, prove anyone was at fault. It describes what was required or what was learned.

Why an Explosion Alone Does Not Prove Your Claim

Many injured workers reasonably assume that an explosion this serious speaks for itself. The law does not see it that way. A civil claim has to be built from specific elements, and an injury, however severe, does not prove anyone's fault.

The most common framework is negligence, meaning a failure to use the care the law expects in the circumstances. It has four parts. A duty is a legal obligation to act with care toward someone. A breach is a failure to meet that obligation. Causation means the breach actually led to the harm. Damages are the losses that resulted. Each element has to be supported by evidence, and in a refinery case the duty and breach questions often lead straight to the safety programs, procedures and records that governed the unit.

Two other theories often sit alongside negligence. Product liability is the body of law that can make a manufacturer or seller answerable when a product, such as a valve, vessel, gauge or other component, is alleged to have been defective and to have caused harm. Premises liability is the law about the duties owed by whoever owns or controls property to people lawfully on it, which matters when a contract worker is hurt at a facility run by someone other than their employer.

Whether any of these elements can be met depends on the facts and on the law of the state where the explosion happened. For you, that means the strength of a claim is set less by how bad the day was than by what the records and witnesses show about who knew what, and when. An early question is which of these theories fits the role each company played: who employed you, who ran the unit and what equipment was involved.

Which Safety Rules Applied to the Unit Where You Were Hurt

Refineries handle the kinds of materials that federal rules treat with particular caution. The process safety management standard states that its purpose is preventing or minimizing the consequences of catastrophic releases of toxic, reactive, flammable or explosive chemicals, which may result in toxic, fire or explosion hazards.

Under 29 C.F.R. § 1910.119(a)(1), the standard applies to a process involving a chemical at or above the threshold quantities listed in its appendix A, and to a process involving a Category 1 flammable gas or a flammable liquid with a flashpoint below 100 °F, on site in one location, in a quantity of 10,000 pounds or more. That second category has exceptions: hydrocarbon fuels used solely for workplace consumption as a fuel, such as propane for comfort heating, when not part of a process containing another covered chemical, and flammable liquids stored in atmospheric tanks or transferred while kept below their normal boiling point without chilling or refrigeration. The standard also does not apply to retail facilities, oil or gas well drilling or servicing operations, or normally unoccupied remote facilities.

Whether a liquid in the unit counted as flammable is itself a defined question. Under 29 C.F.R. § 1910.106(a)(19), a flammable liquid is any liquid having a flashpoint at or below 199.4 °F, divided into four categories by flashpoint and boiling point, with rules for handling a liquid heated to within 30 °F of its flashpoint as a more hazardous category. The details of what was in the line or vessel can therefore shape how the law views the hazard you were working around.

These definitions matter to an injured worker because whether a unit was a covered process can decide which written safety duties applied to it, and so which records a company was expected to keep. If no one establishes what was running in the unit and in what amounts, the duties that point toward a responsible company can be harder to identify.

Maintenance and turnaround work, when units are opened, repaired or restarted, brings additional people and tasks into hazardous areas. The welding and cutting rules in 29 C.F.R. § 1910.252(a) say cutting or welding shall not be permitted in the presence of explosive atmospheres, including those that may develop inside uncleaned or improperly prepared tanks or equipment, and require management to advise all contractors about flammable materials or hazardous conditions of which they may not be aware. Warnings, alarms and permits are part of how a facility controls that work, and whether they were in place and followed is a factual question in each case. For a contract worker, that question often points toward the host facility as well as the employer.

Who May Be Responsible When Your Employer Was Not the Only Company on Site

Your employer is often not the only company whose conduct matters. Refineries commonly bring several businesses onto the same unit, and the law asks different things of each.

The refinery's owner or operator, when it is not the injured person's employer, may face questions under premises liability and under the contractor provisions of the process safety standard. Under 29 C.F.R. § 1910.119(h)(2), which applies to contractors doing maintenance or repair, turnaround, major renovation or specialty work on or adjacent to a covered process, the host employer must obtain and evaluate information about a contractor's safety performance and programs when selecting it; inform contract employers of known potential fire, explosion or toxic release hazards related to the work and the process; explain the applicable parts of the emergency action plan; develop and implement safe work practices controlling contract workers' entrance, presence and exit in covered process areas; periodically evaluate contract employers' performance; and maintain a contract employee injury and illness log. That paragraph does not apply to incidental services that do not influence process safety, such as janitorial work, food and drink services, laundry, delivery or other supply services.

A contractor or subcontractor has its own obligations. Under 29 U.S.C. § 654(a), each employer the Act covers must furnish employment and a place of employment free from recognized hazards that are causing or are likely to cause death or serious physical harm to its employees, and must comply with the occupational safety and health standards issued under the Act. The process safety standard separately requires contract employers to train their workers, instruct them on known hazards and the emergency plan, document that training, and advise the host employer of unique hazards their work presents or finds.

An equipment or component manufacturer may be at issue under product liability when a device, valve, vessel or part is alleged to have failed. A maintenance company may be at issue when contracted maintenance on the equipment involved is part of the story.

The list of potentially responsible parties is therefore a question of roles and control, not of who signed the paycheck. Comparative fault and contributory fault rules, which affect how responsibility is shared among parties, differ by state.

The Records That Can Show What Happened to You, and Who Holds Them

Records tend to carry these cases, because the people closest to the event are often hurt, grieving, or still employed by one of the companies involved. The records that usually matter fall into a few groups, and some of them sit with the very companies whose conduct is in question.

The first is the work of public agencies. If the U.S. Chemical Safety and Hazard Investigation Board investigates the explosion, its report may be one of the few independent accounts available to a family. By its own description, the Board is an independent nonregulatory federal agency that investigates the facts, conditions, circumstances and cause or probable cause of accidental chemical releases that result in a fatality, serious injury or substantial property damage. It conducts root cause investigations, does not issue fines or citations, and makes safety recommendations. Its investigators interview witnesses, obtain documents, send chemical samples and equipment to independent laboratories, and examine company safety records, inventories and operating procedures. Its reports are public, but a root cause stated in a report is not a court's finding of fault. OSHA inspection records and citations are official records too, and they describe what an agency found or alleged, not a decision about civil liability. OSHA's worker rights page states that workers have the right to report an injury or illness, get copies of their medical records, and review records of work-related injuries and illnesses.

The second group belongs to the companies: the facility's incident and accident reports, maintenance and inspection logs for the equipment or process involved, work permits, training records, and the contract employee injury and illness log the process safety standard requires host employers to keep.

The third is personal. Injured workers and families often keep medical records documenting the injuries and treatment, photographs, video and any physical items from the scene, and the names and contact information of coworkers who saw what happened.

Which of these records matters most depends on the facts. The personal records are the ones already within reach, while the company and agency records are where the answers to the duty and breach questions are likely to be found. Because the company records stay in the hands of the companies involved, and witnesses move on or forget details, a worker or family who waits may find the evidence on who controlled the unit thinner than it was in the weeks after the explosion.

Injuries a Refinery Explosion Can Cause and What the Law May Allow

Families often describe the hardest part as not knowing what the next year looks like: whether a worker will return to the same job, or any job. The legal system answers that question in its own terms.

Claims arising from refinery explosions commonly involve blast and pressure-wave injuries, traumatic brain injury, hearing loss and ear injuries, respiratory and inhalation injuries, and orthopedic and crush injuries, along with burns. This page does not describe symptoms or treatment, and nothing here is medical advice.

In a civil claim, the categories of damages the law may allow commonly include past and future medical expenses, lost wages and loss of earning capacity, meaning the reduced ability to earn in the future, pain and suffering, and loss of consortium, meaning the harm to a spouse or family relationship. Which categories apply, and how they are measured, depends on the state's law and on what the evidence shows.

When a worker dies, wrongful death is the legal claim available to certain family members when a person dies as a result of another's conduct. Who may bring that claim, and what damages it may include, differ by state.

The long-term picture, including future care and future work, becomes part of the legal question, which is why treatment records over time tend to matter as much as the first hospital chart. How the injured person's work history and earnings are documented also bears on the earnings categories.

Why the State Where It Happened Shapes Your Options

Federal safety rules apply nationwide, but they do not decide who may sue, by when, or for what. State law does, and the rules differ materially from one state to the next.

A statute of limitations is the deadline the law sets for filing a lawsuit. Each state sets its own periods for injury and wrongful-death claims, and each defines when the period begins to run and what exceptions apply. This page states none of them, because no single period applies everywhere.

If you share some responsibility for what happened, the state's fault rule decides what that means for a claim. Comparative fault is the rule that reduces or bars recovery based on the injured person's own share of responsibility; some states use a contributory fault rule instead, and states differ in how each works. Which losses can be recovered also depends on the state, including which damages categories are allowed and whether any are limited.

Workers' compensation rules differ by state as well, and they can affect whether any civil claim against an employer is available at all. Federal law leaves those rules in place: 29 U.S.C. § 653(b)(4) says the Occupational Safety and Health Act shall not be construed to supersede or in any manner affect any workmen's compensation law, or to enlarge, diminish or affect the common law or statutory rights, duties or liabilities of employers and employees for work injuries, diseases or deaths.

A conversation with an attorney can help sort out which state's rules may apply, which companies' roles fit which theories, and how the timing works; you can request a case evaluation.

What to Have in Mind Before Speaking With a Refinery Explosion Attorney

A first conversation about a refinery explosion usually covers the same ground, and having the facts gathered tends to make it more useful. Much of it connects to the questions above: who controlled the unit, which records exist, and which state's law applies. The information that often comes up includes:

• What happened and when: the date, the unit or area, and the general sequence of events as you understand it.
• The employment relationship: who you worked for, whether contractors or a maintenance company were on site, and who directed the work in that area.
• The injuries diagnosed and the treatment received so far.
• The records you have or know exist, such as incident reports, medical records, photos and permits.
• Whether OSHA or the Chemical Safety Board has opened an investigation.
• Whether a workers' compensation claim has been filed.
• Whether you raised safety concerns and believe you were punished for it, since federal law sets a short separate window for a retaliation complaint, discussed in the FAQ below under 29 U.S.C. § 660(c).

A case evaluation is a conversation about what happened. It does not promise any outcome, and it does not mean our attorney will take the matter. Readers whose injury came from a pipeline project or a well site rather than a refinery will find those situations discussed on the site's pages about pipeline site accidents and oilfield accident claims; refinery accidents other than explosions are also treated separately on the site.
