No one researches plant explosion attorneys unless something has already gone wrong. You or someone you care about was injured (or killed) at a Louisiana refinery, chemical plant, or industrial facility. You are trying to figure out what your options are.
This page explains how third-party tort claims work after refinery and plant accidents in Louisiana. It covers who can be held liable beyond workers' compensation, what federal and state safety standards mean for your case, and what evidence matters most. Morris & Dewett has handled industrial injury cases for 25 years. Read this. Do your research. Reach out when you're ready.
Louisiana's Refinery Industry and Why These Cases Are Different
Louisiana is one of the most concentrated petrochemical states in the country. The Baton Rouge industrial corridor runs from ExxonMobil's Baton Rouge complex through Shell Norco, Honeywell Baton Rouge, and BASF Geismar. Lake Charles hosts Citgo Lake Charles, Westlake Chemical, and Sasol Lake Charles. The New Orleans and St. Charles corridor includes Valero St. Charles and the Shell Norco complex. These facilities employ thousands of workers, most of whom are not employed directly by the operating company.
That employment structure is the foundation of refinery tort law. At any given time, a refinery or plant has workers from the operating company, turnaround and maintenance contractors, specialty subcontractors, and equipment vendors on site. When an incident occurs, the legal question is not just whether someone was negligent. The question is which party's negligence caused the incident and whether that party can be sued in tort.
Workers' compensation exclusivity generally bars a lawsuit against your own employer. It does not bar a lawsuit against the contractor who brought defective equipment onto the job, the turnaround company whose employee violated a hot work permit, or the engineering firm that designed a pressure relief system that failed. Those third-party claims are separate from workers' comp and carry no cap on pain-and-suffering damages.
Ask any attorney you consult whether they have specifically evaluated your third-party claim options. Workers' comp is the minimum. An attorney who focuses only on comp without analyzing third-party liability is not fully representing your interests.
Types of Incidents: Explosions, Fires, and Chemical Releases
Refinery and plant incidents follow recognizable patterns. Understanding the type of incident matters because it shapes who is liable and what evidence to preserve.
Vapor Cloud and Pressure Vessel Events
A VCE occurs when a flammable gas or liquid release disperses into a vapor cloud that then finds an ignition source. The overpressure wave causes structural damage and bodily injury far from the release point. Blast pressure injuries, flying debris, and secondary fires are all common results. The causation question focuses on what caused the initial release: a pipe failure, a valve malfunction, a maintenance error, or a flawed process change.
A BLEVE is a specific type of pressure vessel failure involving superheated liquids. LPG storage, propane vessels, and butane units are common sources. When the vessel fails, the liquid flashes to vapor instantly and ignites. Anyone in the fireball radius sustains thermal injury. The pressure wave causes structural and blast injuries at a wider radius.
Flash fires differ from explosions. A flash fire occurs when a flammable vapor cloud ignites without detonation. There is no pressure wave, but anyone inside the flammable envelope sustains severe thermal burns. The primary cause is typically an uncontrolled release from a flange, valve, pump seal, or pipe connection. Ask any attorney you consult whether they have worked with a fire and explosion dynamics expert who can reconstruct the flammable zone and place your location within or outside it.
Chemical Releases
Chemical releases at Louisiana plants involve some of the most hazardous substances in industrial use. Hydrogen fluoride (HF) acid is present in alkylation units at refineries throughout Louisiana. Ammonia is used in refrigeration systems and reacts explosively with certain other chemicals. Benzene is a known human carcinogen present in crude oil and a component of several refining streams. H2S is present in virtually every crude oil refining and natural gas processing operation. Nitrogen asphyxiation in confined spaces is a frequent cause of death at plants where nitrogen is used as a purge or blanketing gas.
Each of these substances has specific regulatory handling requirements. Failures to implement those requirements are the evidence base for third-party chemical supplier, operating company, or contractor liability. Baton Rouge General and other hospitals in the industrial corridor maintain specialized decontamination and toxicology protocols specifically for these exposures.
Hot work permit violations are a separate and recurring cause of refinery fires and explosions. Hot work (welding, cutting, grinding) without proper atmospheric testing is negligence per se under OSHA PSM regulations. If a contractor performed cutting or welding without verifying the area was gas-free, and a fire resulted, the contractor's failure to follow the hot work permit system is a direct liability basis.
Who Is Liable: Third-Party Defendants in Refinery Cases
Liability in a refinery incident is rarely limited to one party. Louisiana follows a system of comparative fault under which multiple parties can be assigned fault percentages, and each defendant pays according to their share.
Turnaround and Maintenance Contractors
Refineries and plants schedule periodic shutdowns called turnarounds to perform maintenance, inspections, and equipment replacement. During a turnaround, the facility employs far more workers than during normal operations, most of them from outside contractors. Turnaround contractors are responsible for the safety of their own crews and for the work procedures their employees follow.
If a turnaround contractor's employee failed to gas-free a line before cutting, failed to use proper lockout/tagout, or ignored a permit requirement, that contractor is liable in tort to anyone injured as a result. This liability exists even if the injured worker is employed by a different company on the same job. The contractor's duty of care runs to all workers in the area, not just its own employees.
Ask any attorney you're considering whether they have deposed turnaround contractors before and whether they understand how to obtain master service agreements, safety management plans, and toolbox talk records from the contractor's files.
Equipment Manufacturers and Product Defects
Pressure relief valves, heat exchangers, control systems, and instrumentation can fail due to design defect or manufacturing defect. Under the Louisiana Products Liability Act (La. R.S. 9:2800.54), a manufacturer is liable if a product is unreasonably dangerous in construction, design, or due to inadequate warning. Strict liability applies to product claims. You do not need to prove the manufacturer was careless, only that the product was defective.
Common product claims in refinery cases include pressure relief valves that failed to open at rated pressure, heat exchangers with tube bundle defects that allowed cross-contamination between process streams, and electronic safety systems that failed to activate automated shutdowns.
Engineering and Design Firms
Front-end engineering design (FEED) firms and detailed engineering firms that designed inadequate pressure relief systems, specified incorrect materials for service conditions, or produced flawed piping designs can be liable for design defect under both Louisiana Products Liability Act theories and general negligence. If the root cause of your incident traces to an engineering error, the engineering firm that made it carries liability.
Chemical Suppliers
Suppliers of reactive or hazardous chemicals have a duty to properly label their products, provide accurate safety data sheets, and warn of known hazards specific to the conditions of use. Failures in labeling, inadequate warning of reactive hazards, or supplying a chemical with off-specification properties can support a third-party claim against the supplier. The Louisiana Products Liability Act governs these claims.
Federal and State Safety Standards as the Negligence Benchmark
The regulations governing refinery safety are detailed and prescriptive. Violations of those regulations by a third-party defendant are evidence of negligence. In many cases they satisfy negligence per se.
OSHA's Process Safety Management standard (29 C.F.R. 1910.119) applies to any process that uses threshold quantities of highly hazardous chemicals. PSM requires written operating procedures, mechanical integrity inspection programs, hot work permit systems, Management of Change documentation, and written incident investigation following any near-miss or incident. A defendant who violated any of these requirements has violated a federal safety standard. That violation is direct evidence of negligence.
RAGAGEP is the standard PSM requires facilities to apply. It includes American Petroleum Institute (API) standards for inspection and equipment integrity, American Society of Mechanical Engineers (ASME) codes for pressure vessels, and National Fire Protection Association (NFPA) standards for fire and explosion prevention. When a defendant departed from RAGAGEP, your attorney can establish a specific standard of care and show precisely how the defendant fell short of it.
The EPA Risk Management Program (40 C.F.R. Part 68) requires covered facilities to analyze worst-case release scenarios and implement prevention programs. Louisiana OSHA (LOSH) administers state-level workplace safety regulations, and LOSH citations are admissible evidence of negligence in civil claims. The U.S. Chemical Safety and Hazard Investigation Board (CSB) investigates major industrial incidents and publishes detailed reports that are frequently used in litigation. The CSB investigated multiple Louisiana incidents, including explosions at the Dow Plaquemine facility in Iberville Parish in 2023.
Ask any attorney you consult whether they have used RAGAGEP departure as a liability theory and whether they have worked with a process safety engineer as a testifying expert. This is specialized territory.
The Louisiana Oilfield Anti-Indemnity Act and Its Effect on Your Claim
La. R.S. 9:2780, the Louisiana Oilfield Anti-Indemnity Act (LOIA), is a statute that directly affects how fault and financial responsibility are allocated in multi-party industrial cases. Understanding it matters if you want to evaluate whether your attorney is capturing all available recovery.
Operating companies and contractors routinely include broad indemnity clauses in master service agreements. These clauses often require the contractor to indemnify the operating company even for the operating company's own negligence. LOIA voids those clauses. When LOIA applies, the operating company cannot use contractual language to shift its liability to a smaller contractor and walk away from the case.
The practical consequence is that the operating company remains exposed for its own negligent acts regardless of what the contract says. In a case where both the operating company and a contractor contributed to the incident, LOIA prevents the operating company from using indemnity language to reduce the pool of recovery available to you. It also prevents a contractor from using indemnity language to push liability back to you.
LOIA litigation requires an attorney who reads master service agreements carefully and knows which clauses LOIA voids and which it does not. Attorneys without specific experience in refinery multi-party litigation frequently miss these issues.
Evidence in Plant and Refinery Cases
Evidence in refinery cases is technical, voluminous, and perishable. The most important evidence must be preserved immediately.
Send a litigation hold letter to all potential defendants as soon as possible after the incident. DCS data and alarm historian logs record process conditions at the time of the incident. Those records can be overwritten within days or weeks on normal system maintenance cycles. Incident investigation reports, which OSHA PSM requires to be prepared within 48 hours of any incident, are primary evidence of what the responsible parties believed went wrong.
The PHA and mechanical integrity records tell you what the facility knew about its own hazards. Mechanical integrity inspection records (thickness measurements, corrosion logs, repair histories) show whether the facility was actually performing the inspections its PSM program required. Gaps in those records support failure-to-maintain theories.
Management of Change documentation and hot work permit logs round out the documentary evidence base. Expert witnesses in refinery cases include process safety engineers, mechanical integrity specialists, explosion dynamics and fire investigation experts, and toxicologists. These cases require multiple experts working together.
Morris & Dewett retains process safety experts and explosion dynamics specialists on refinery and plant cases. Ask any attorney you consult who their retained experts are and whether those experts have testified in refinery cases involving the specific type of incident you experienced.
Louisiana Tort Reform and Industrial Injury Deadlines
Two legal deadlines govern your refinery or plant injury claim in Louisiana.
The Prescriptive Period for personal injury is two years from the date of injury under La. C.C. Art. 3493.11, which became effective July 1, 2024. Wrongful death claims carry a two-year prescriptive period from the date of death. This is a hard deadline. Missing it forfeits your right to recover regardless of how strong your case is.
Louisiana's Comparative Fault rule under La. C.C. Art. 2323, as amended effective January 1, 2026, applies a 51% bar. If you are 51% or more at fault, you recover nothing. Below 51%, your damages are reduced by your fault percentage.
In multi-party refinery cases, defendants routinely try to push your fault percentage above 50%. They argue you removed PPE, failed to comply with a permit requirement, or deviated from a procedure. This is why establishing what each party was required to do under PSM and RAGAGEP matters. Your attorney must be prepared to rebut comparative fault arguments with specific regulatory standards showing what the defendant was required to do and failed to do.
The workers' comp exclusivity rule in Louisiana bars a tort claim against your direct employer. It does not bar a tort claim against a third party. The threshold question is whether the defendant qualifies as your statutory employer under Louisiana law. An attorney evaluating your case must analyze that question before concluding that any particular defendant is immune from suit. Ask any attorney you consult whether they have specifically addressed statutory employer status for each potential defendant in your case.
Wrongful Death and Survival Actions
When a worker is killed in a refinery explosion, fire, or chemical release, two legally distinct claims exist under Louisiana law and can be pursued simultaneously.
A survival action under La. C.C. Art. 2315.1 recovers the victim's own damages between injury and death. This includes pain and suffering during any period of survival, medical expenses, and lost wages during that period. It is brought by the estate.
A wrongful death action under La. C.C. Art. 2315.2 recovers the family's own damages. These include loss of financial support, loss of companionship and love, and funeral and burial expenses. Louisiana law specifies who can bring this claim: surviving spouse and children first, then parents, then siblings. A higher-priority claimant's existence bars lower-priority claimants.
Both actions are brought against the same third-party defendants. Neither is limited by workers' compensation because workers' comp does not apply to third-party tort claims.

Frequently Asked Questions
- I was injured at a refinery but I already filed a workers' comp claim. Can I still sue a third party?
-
Yes. Filing a workers' compensation claim does not bar a third-party tort lawsuit. Workers' comp covers your direct employer. It has no effect on your right to sue a contractor, equipment manufacturer, chemical supplier, or engineering firm whose negligence caused your injury. Third-party tort claims are evaluated separately and carry no cap on pain-and-suffering damages. In many refinery cases, the third-party claim is the primary source of full recovery.
- What is a turnaround contractor and why does it matter for my case?
-
A turnaround contractor is a company hired by the operating facility to perform scheduled maintenance, inspection, and equipment replacement during a planned shutdown. During turnarounds, the facility workforce expands significantly with outside contractor crews. Turnaround contractors are responsible for the safety of their workers and their work procedures. If a turnaround contractor's employee or procedure caused your incident (a hot work permit violation, improper lockout/tagout, or a line opening error), that contractor is liable in tort to anyone injured as a result, including workers from other companies on the job.
- How does the Louisiana Oilfield Anti-Indemnity Act affect a refinery injury lawsuit?
-
[La. R.S. 9:2780](https://legis.la.gov/legis/Law.aspx?d=79573) voids broad indemnity clauses in oilfield and industrial master service agreements that would otherwise require one party to indemnify another for the indemnitee's own negligence. In practice, this means the operating company cannot use contract language to transfer all liability to a smaller subcontractor. Each party remains exposed for its own negligent acts. LOIA is critical in multi-party refinery cases because it prevents defendants from contractually eliminating themselves from liability, which directly affects how much total recovery is available.
- What is RAGAGEP and how is it used to prove negligence?
-
RAGAGEP stands for Recognized and Generally Accepted Good Engineering Practices. It is the body of industry standards (API, ASME, NFPA, AIChE) that [OSHA's PSM standard (29 C.F.R. 1910.119)](https://www.osha.gov/process-safety-management) requires refinery and plant operators to apply. In litigation, a process safety expert compares what the defendant actually did against what RAGAGEP required. Departure from RAGAGEP establishes a specific standard of care and a specific failure. It is a more precise liability theory than general negligence because it identifies the exact published standard the defendant was required to follow.
- How long do I have to file a lawsuit after a refinery accident in Louisiana?
-
Two years from the date of injury under [La. C.C. Art. 3493.11](https://legis.la.gov/legis/Law.aspx?d=2535543), effective July 1, 2024. For wrongful death, two years from the date of death under the same statute. This is a hard deadline. There is no grace period. If your incident occurred before July 1, 2024, verify the applicable prescriptive period with an attorney because the prior one-year rule may apply. Evidence preservation begins immediately. DCS data and alarm historian logs can be overwritten before the deadline even approaches.
- What evidence do I need to preserve immediately after a refinery explosion or fire?
-
Send a litigation hold letter to all potential defendants immediately. The priority evidence is: DCS and alarm historian data from the time of the incident; the PSM incident investigation report (required within 48 hours); hot work permits and atmospheric test logs for the work area; mechanical integrity inspection records for equipment involved; and Management of Change documentation for any process or equipment changes made in the months before the incident. This data exists on facility systems and paper files and can be overwritten, modified, or destroyed on normal retention schedules without a formal preservation demand.
- My employer says the accident was my fault. What happens if I am found partially at fault?
-
Louisiana uses a comparative fault system under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109387) (effective January 1, 2026). If your fault is 50% or less, your damages are reduced proportionally. 20% fault means 20% reduction in recovery. If you are found 51% or more at fault, you recover nothing. In multi-party refinery cases, defendants routinely argue that workers violated procedures or removed PPE. Your attorney must rebut these arguments with the specific PSM and RAGAGEP requirements that governed what the defendant was obligated to do. Establishing what each party's duties were is the key to defending against comparative fault arguments.
- Can family members recover if a worker was killed in a refinery explosion?
-
Yes. Two separate claims exist under Louisiana law. A survival action under [La. C.C. Art. 2315.1](https://legis.la.gov/legis/Law.aspx?d=109318) recovers the victim's own damages between injury and death: pain and suffering, medical costs, and lost wages during survival. A wrongful death action under [La. C.C. Art. 2315.2](https://legis.la.gov/legis/Law.aspx?d=109319) recovers the family's damages: loss of financial support, loss of companionship, and funeral costs. Surviving spouses and children are the first-priority claimants. Both claims are brought simultaneously against the same third-party defendants and are not limited by workers' compensation.
