The short and plain version
- An oil and gas site is full of fuel: crude, gas, vapors, and condensate. Add one spark and you get a fire or an explosion.
- A "flash fire" happens when a cloud of vapor lights up all at once. An explosion happens when that fire is trapped inside something, like a tank, a trench, or a building.
- "Hot work" means welding or cutting. It is one of the leading causes, above all around tanks nobody tested for vapors first.
- A serious burn is one of the most painful and life-changing injuries there is. It often means surgery after surgery, and scars that stay.
- Gas monitors, hot-work permits, and flame-resistant clothes all exist to stop exactly this.
- So when a company skips the permit or the monitoring, a burn is the predictable result of that choice.
1. Why the oil patch is full of fuel and ignition
An oilfield burn does not heal the way other injuries heal. It means surgery after surgery, skin grafts, scarring that never fully fades, and pain that outlasts the hospital stay by years. And almost every one of these fires traces back to something that should have been checked and was not.
This page explains how oilfield fires and explosions actually happen. It covers the safety rules that are supposed to stand between you and them, and who can be held responsible when those rules get skipped.
Start with something firefighters teach on day one. Every fire needs the same three things: fuel, oxygen, and an ignition source (a spark, a flame, or enough heat). They call it the “fire triangle.” Take away any one side and there is no fire.
Now think about what an oil and gas lease actually is. The fuel side of that triangle is the product itself. Crude oil sitting in the tanks. Natural gas in the wellbore and the lines. Condensate (workers call it “drip gas,” the light liquid that falls out of the gas stream) that lights easier than gasoline. Vapors rising off every hatch, vent, and spill. The oxygen side is just the air. So on a lease, two of the three sides are already there, all day and every day, and no company can take them away.
That means everything comes down to the third side: controlling ignition. Welding sparks. Cutting torches. Grinders. Hot engines and exhaust pipes. Electrical gear. Static. Even a truck idling too close to a tank battery (a group of storage tanks connected by piping). The industry has understood this for more than a century. The rules for controlling every one of those ignition sources are already written down. So when a worker gets burned, “freak accident” is usually the wrong phrase. Somebody let fuel and fire find each other.
And a fire does not check property lines. The same vapor cloud that burns a crew can drift toward a county road or a neighbor’s fence. A company that gets careless with ignition is gambling with its crew first and the community second.
2. Flash fires, explosions, and pipeline ruptures
Fire hurts oilfield workers in three main ways, and they behave differently.
A "flash fire" is a wall of flame that sweeps through a cloud of gas or vapor the instant the cloud finds an ignition source. It lasts only seconds. But it moves faster than a man can run, and it can cover a worker from head to toe.
The cruel part is that the cloud is usually invisible. Gas or vapor leaks or vents, mixes with the air, and drifts, sometimes a long way from the tank or line it came out of. The worker never sees it. Then a spark or a hot surface touches the cloud, the whole thing lights at once, and anybody standing inside the cloud is standing inside the fire. Regular work clothes catch fire in those seconds and keep burning after the flash is gone. That is often where the deepest burns come from, and it is exactly why flame-resistant clothing exists. We will get there.
An explosion is what happens when burning gas has nowhere to go. When vapor ignites inside a closed space (a tank, a building, a trench, a vessel), the pressure builds in a fraction of a second and the container gives way. Workers near it face the blast, flying steel, and burning liquid, often all three at once.
The classic example in the oil patch is the tank battery. Above the crude inside every storage tank sits a “vapor space” (the gas-filled gap between the liquid and the roof), and the air in that space is often an explosive mixture waiting on a spark. The tanks are usually connected to each other by piping, so vapor travels from tank to tank. A spark at one hatch can blow up a tank nobody was touching. Federal safety investigators have documented that exact chain of events again and again. One of those cases is in the next section.
Then there are the lines. A lease is stitched together with flowlines and gathering lines (the smaller pipelines that move oil, gas, and produced water around the site and off of it). Bigger transmission lines may cross the same ground. Lines corrode. Welds fail. Fittings get struck by equipment. When a pressurized gas line lets go and the gas finds a spark, it can burn like a blowtorch the size of a building until somebody shuts the line in. Pipeline failures are their own subject with their own federal rules, and they get their own guide: the pipeline injuries guide (coming soon).
One more South Texas wrinkle. If the gas is “sour” (carrying hydrogen sulfide, a poison gas), a leak is doing two jobs at once: poisoning the air and fueling a fire. The poison side of that story is covered in the H2S exposure guide.
Explosions are one of the biggest killers in the oil patch.
Federal researchers identified 470 oil and gas extraction workers killed on the job from 2014 through 2019. Explosions killed 14.5 percent of them, about 1 in every 7. Only vehicle crashes and "contact" injuries (workers struck by or caught in equipment) killed more.

"Hot work" is any job hot enough to start a fire: welding, cutting with a torch, grinding, brazing, or anything else that throws sparks or flame. On a site full of fuel, hot work is the moment the ignition side of the triangle shows up on purpose. That is why it comes with its own strict set of rules.
Tanks crack. Piping needs replacing. Steel needs cutting. So welding and cutting happen on live oil and gas sites every single day, and done right, with the air tested and the tanks cleaned out, hot work gets done safely all over Texas. Done wrong, it is one of the most reliable ways this industry kills people.
The U.S. Chemical Safety Board (the federal agency that investigates chemical disasters) has counted more than 60 workers killed since 1990 in explosions and fires from hot work on tanks alone. The same failures kept repeating, so in 2010 the agency put out a safety bulletin called “Seven Key Lessons to Prevent Worker Deaths During Hot Work In and Around Tanks.” The heart of it is simple. Before anybody strikes an arc, somebody has to actually check whether the air can burn, and keep checking while the work goes on.
The "lower explosive limit," or LEL, is the lowest amount of gas or vapor in the air that can catch fire and carry a flame. Below that level, the mix is too lean to burn. The tool that measures it is a combustible gas detector (workers call it an "LEL meter" or a "sniffer"). Under the guidance the CSB points to, any detectable reading means stop: find the source and fix it before a single spark flies.
A "hot-work permit" is a written authorization that is supposed to come before the sparks. A person responsible for fire safety walks the area first, tests the air with a gas meter, makes sure tanks and lines have been drained, purged, and "gas-freed" (cleaned and vented until no flammable vapor is left), sets the required precautions, and signs off. One honest nuance: OSHA's rule technically requires the area to be inspected and the work authorized, "preferably" with a written permit, so the paper itself is the preferred method rather than a flat mandate. But industry practice under API RP 54 treats a written permit as standard. And if nobody can produce one after a fire, that absence is powerful evidence of what did not happen that day.
The law backs this up. OSHA’s welding, cutting, and brazing standard, 29 CFR 1910.252, requires the area to be inspected by a designated person who authorizes the work, preferably with a written permit. It requires the hot work moved away from flammables, or the flammables moved away from the hot work. It requires a “fire watch” (a trained person whose only job is watching for fire, extinguisher in hand) in risky spots, staying at least half an hour after the welding stops. It flat-out prohibits welding and cutting in the presence of explosive atmospheres, and on used drums, tanks, or containers that have not been cleaned until no flammable material is left. And it requires management to warn outside contractors about flammable hazards they may not know about. The industry wrote the same expectations into its own rulebook, API Recommended Practice 54, which calls for hot-work permits wherever a flammable atmosphere could exist.
Here is what it looks like when all of that gets skipped, documented by the CSB in that same bulletin. On June 5, 2006, at the Partridge-Raleigh oilfield in Mississippi, a contract crew was welding new pipe between crude oil storage tanks. Sparks from the welding ignited vapor venting out of a tank a few feet away. Two tanks exploded. Three workers standing above them were killed, and a fourth was seriously injured. The CSB found that neither the operator nor the contractor required written hot-work permits. The contractor had given its crew no hot-work safety training. And the operator had no safety requirements for its contractors at all.
Not one of those safeguards was expensive. Every one of them was a choice. Three men paid for those choices, and their families are still paying.
4. What a serious burn really means for a worker
I want to be straight with you about this part, because the insurance company will spend the whole case trying to shrink it.
Doctors grade burns by depth. First-degree burns hurt the surface, like a sunburn. Second-degree burns go into the deeper layers of skin, blister, and hurt badly. Third-degree burns (doctors say “full thickness”) kill the skin all the way through, nerve endings included. Skin that dead cannot grow back. It has to be replaced.
Replacing it means skin grafts, where surgeons shave healthy skin from another part of your body and secure it over the burn. The place they take it from (the “donor site”) becomes a second wound with its own pain. Before the grafts can even happen, there is “debridement,” the scrubbing and cutting away of dead and contaminated tissue, repeated over and over. Burn survivors describe it as some of the worst pain in medicine. All of this usually happens in a burn ICU over weeks or months, often far from home, because true burn centers are scarce. So the family ends up living out of a motel while the paychecks have already stopped. And the whole time, infection is a standing threat, because skin is the body’s shield and the fire took it.
Surviving the hospital is the start, though, and nobody warns families about that. Burn scars tighten as they heal (doctors call the result “contractures”). That tightening can pull a hand, an arm, or a neck out of its normal range of motion, which means more surgeries, sometimes years of them. Badly burned skin may never sweat right again, so Texas heat itself becomes a hazard. Faces and hands change, and people stare. The mental side is real too: nightmares, flashbacks, post-traumatic stress, a man who cannot stand the smell of a cutting torch anymore. And if he breathed the fire (“inhalation injury,” hot gas and smoke burning the airway and lungs), the damage goes inside as well.
The hospital bills are the smallest honest measure of a serious burn. The years are the real bill.
If you are reading this from a burn unit, whether you are the one in the bed or the one keeping watch beside it, you do not have to sort any of this out today. When you are ready to understand what your family is looking at, that conversation is free, it is private, and it moves at your pace.
Call or text (210) 460-05695. The safety rules that should have prevented it
If the last section made you angry, this one explains why you should stay that way. The danger of fire on an oil and gas site is famous. The protections against it are written down, layer after layer, and they have been for decades. When a serious burn happens anyway, the honest question is which layer was missing that day, and whose job it was to have it there.
Layer 1: the hot-work rules. Covered above. Inspection, authorization, a written permit as the preferred practice, a fire watch, and a flat prohibition on welding near explosive atmospheres or on uncleaned tanks, all under 29 CFR 1910.252.
Layer 2: the flammable-liquids rules. OSHA’s flammable liquids standard, 29 CFR 1910.106, says that where flammable vapors may be present, ignition sources have to be eliminated or controlled. It lists them: open flames, cutting and welding, hot surfaces, sparks, static. It also says hot work in those areas is allowed only under the watch of a responsible person, who has to inspect the area first.
Layer 3: the catch-all. Even where no specific rule fits, Section 5(a)(1) of the federal OSH Act, the “General Duty Clause,” requires every employer to keep the workplace free of recognized hazards likely to cause death or serious harm. Fire on a lease is about as recognized as a hazard gets.
Layer 4: the clothes.
"Flame-resistant clothing" (workers say "FRs") is work clothing built to stop burning once the flame source is gone, instead of catching fire and continuing to burn like ordinary cotton, or melting into the skin like polyester. FRs will not make anybody fireproof. What they are built for is the few seconds of a flash fire, and those seconds often decide how deep and how wide the burns go.
Since 2010, OSHA has taken the enforcement position that it may cite oil and gas employers under the general protective-equipment rule (29 CFR 1910.132(a)) when workers face flash-fire danger in drilling, well servicing, and production work without FRs, even though that rule never mentions flash fires or FR clothing by name. That position is spelled out in OSHA’s enforcement policy memorandum of March 19, 2010. The garment standard the industry relies on is NFPA 2112, which tests clothing on an instrumented manikin in a simulated three-second flash fire. Its companion, NFPA 2113, covers how FRs get selected, worn, and maintained. So if a crew was doing flash-fire work in street clothes, that was somebody’s policy decision, and it left a paper trail.
Layer 5: the industry’s own rulebook. API RP 54 and NFPA 2112 and 2113 are voluntary industry standards, not government regulations. They were written and published by the industry’s own trade groups. But a company can hardly claim surprise at safety expectations its own trade association put in writing.
Stack those layers up and look at them. Air testing. Permits. Fire watches. Gas-freed tanks. FRs. Every layer on that list exists because workers already died proving it was needed. So when a company shrugs and calls a fire bad luck, somebody should ask which layer was missing, because in the incidents federal investigators write up, at least one almost always was.
6. Who is responsible
An oilfield burn case usually starts with a list of companies, because a lease is a stack of them: the operator (the company running the lease), the drilling or workover contractor, the welding or roustabout crew, the companies that own or maintain the tanks and lines, and the ones that made the equipment. When a fire happens, the legal question is which companies’ choices let fuel and ignition find each other. The answer is often more than one:
- The operator, if it knew the tanks and lines were live and let hot work happen anyway, or ran the lease with no permit program and no safety expectations for its contractors.
- The contractor running the hot work, if the crew cut or welded without testing the air or gas-freeing the tanks.
- Whoever owned the permit and the monitoring, if the permit was never issued, or got signed without anybody actually walking the site with a meter.
- An employer that sent workers into flash-fire work without FRs, which, as you saw above, runs against OSHA’s stated enforcement position.
- An equipment or parts company, if a valve, a hatch, a torch, or a gas monitor failed the way defective products fail.
Your own employer is a separate question with its own rules, especially in Texas, where a lot of oilfield employers legally carry no workers’ comp at all. And if the fire took someone from you, the family’s claim is its own case with its own deadlines, explained plainly in the wrongful death guide.
Now the honest hard part. Texas has a law, Chapter 95 of the Civil Practice and Remedies Code, that can make a claim against the property owner (in the patch, often the operator or leaseholder) much harder. To get past it, an injured contract worker usually has to prove both of two things: 1) the owner kept some control over how the work was done, AND 2) the owner actually knew about the danger and failed to adequately warn. One is not enough. And there is a procedural wrinkle a qualified lawyer will know: who has to prove what first can depend on the kind of summary judgment motion the company files. If it files a “no-evidence” motion (a motion claiming the worker has no proof), the burden lands on the worker right away. If it files a traditional motion, the company itself must first conclusively disprove control and knowledge before the worker has to respond. Either way, it is a steep hurdle, and it protects only the property owner, not every company on that lease. The full breakdown is in the Chapter 95 guide. But understand why fires make these fights so fact-heavy: permits, gas readings, and safety files are exactly where control and knowledge live. Both of the Texas Supreme Court decisions below came out of explosions.
A short, plain summary of two Texas Supreme Court explosion cases that shape who can be held responsible. This is legal background, not a prediction about any specific case.
- Energen Resources Corp. v. Wallace (Tex. 2022) was an oilfield explosion case. A crew was completing a water well on a lease where the operator was drilling an oil well about five hundred feet away. Gas got into the water well, and the well caught fire and exploded before it was finished. The Court held that Chapter 95 still applied. The gas in the well the crew was working on counted as a dangerous "condition" of that well, even though the workers blamed negligence at the operator's separate oil well, so long as negligence involving the well they were working on was a cause of their damages. On control, the Court held that the operator's geologist recommending the well be drilled deeper was only a recommendation. Suggestions that do not have to be followed, and directing when and where work happens, are not control over how the work is done. One limit worth knowing: Energen's summary judgment motion rested on the control element alone, so the Court did not have occasion to address actual knowledge in that case.
- Ineos USA, LLC v. Elmgren (Tex. 2016) involved a worker replacing a valve on a furnace header at a petrochemical plant. A gas test before the job had read clear, but superheated gas released during the work and burned him. The Court held that Chapter 95 covers all negligence claims against the property owner, and that reaches further than many people expect. It covers "negligent activity" claims (claims about dangerous conduct, and not just dangerous conditions), and it even shields the owner from "vicarious liability" (being held responsible for its own employees' negligence). But that protection belongs to the owner alone. The owner's individual employees and agents get no personal shield from the statute. The Court also treated the plant's connected furnace-and-piping system as one single "improvement." And it held that "actual knowledge" means knowing the dangerous condition existed at the time of the accident, meaning gas in that line, on that day. A general awareness that a plant is full of explosive gas is not actual knowledge.
- The plain takeaway: in fire and explosion cases, the fight gets concrete fast. What did the gas tests show, who signed the permit, what did the operator's own files say about those tanks and lines. That is evidence, it lives on paper and in company files, and it starts disappearing early. That is one reason the first weeks after a burn matter more than most families realize.
If you were burned on a Texas oil and gas site, or somebody has already told you the fire was nobody's fault, call me. The conversation is free, and I will be straight with you about what the permits and gas tests likely show, what Chapter 95 means for your case, and what I would do next if it were my family.
Call or text (210) 460-05697. What this means for you and your family
Here is the plain version of everything above.
A burn from an oilfield fire almost certainly did not have to happen. The industry has known for generations what vapor does when it meets a spark. The air meters, the permits, the fire watches, and the FRs all exist because of that. So if the fire happened anyway, some company probably skipped a layer. And that decision was made by a person in an office who was never going to be standing in the vapor cloud.
Do not let anyone rush you into signing anything. Burns keep changing for years. Scars tighten, surgeries get revised, and needs show up later that nobody mentioned in the hospital. A settlement that only counts the bills so far quietly hands the rest of the cost to your family. The early check is usually designed to close the file before the real size of the injury shows.
And these choices put more than the crew in danger. Tank batteries, vapor clouds, and pipelines sit near ranches, county roads, and homes all over South Texas. Holding a careless company to answer for a fire is also how the next one gets prevented.
If the fire took someone you love, I am sorry, and the wrongful death guide explains what the law allows your family to do, at whatever pace you need.
Burn cases are expert-heavy cases. Proving how a fire started usually takes an "origin and cause" investigator (a fire scientist who reconstructs where it began and what lit it), plus safety experts on permits and monitoring. Proving what the burn will cost usually takes burn surgeons, a "life-care planner" (the expert who prices out every future surgery, therapy, and need, year by year), and an economist for the lost earning power. What each expert does is covered in the experts guide (coming soon), and how those dollars get counted is covered in the damages guide.
8. Questions to ask any lawyer you are considering
You do not have to take anybody’s word, including mine. Test any lawyer you talk to. These questions will tell you quickly whether they know fire cases.
- Ask what a hot-work permit is, and how they would get the permit records, the gas-test logs, and the FR-clothing policy before those things disappear.
- Ask what Chapter 95 is, whether it applies to your case, and which companies on the site it does not protect.
- Ask which experts a burn case needs, and specifically whether they have worked with origin-and-cause investigators and life-care planners.
- Ask how they would prove the future cost of your burns, the surgeries and revisions still coming, and not just the bills so far.
- Ask about their experience with oilfield cases, whether they work with experienced co-counsel when needed, how the fee works, what expenses they cover up front, and what happens if the case does not recover.
A lawyer who knows this work will not be bothered by those questions.

Common questions
What is a flash fire? +
A flash fire is a wall of flame that sweeps through a cloud of gas or vapor the moment the cloud finds a spark or flame. It lasts only seconds, but it can cover a worker completely. It also sets regular clothing on fire, and the clothes keep burning after the flash is gone. The vapor cloud is often invisible, so the fire seems to come out of nowhere. That is why air monitoring and flame-resistant clothing matter so much.
What is hot work and why is it so dangerous? +
Hot work is any task hot enough to start a fire: welding, torch cutting, grinding, and similar jobs. On an oil and gas site, flammable vapor can drift far from the tank or line it came out of. If hot work starts before the air is tested and the tanks are cleaned out, the sparks and the vapor find each other. Federal investigators have tied more than 60 worker deaths since 1990 to hot work around tanks alone.
What is a hot-work permit? +
It is a written sign-off that is supposed to happen before any welding or cutting begins. A responsible person walks the area, tests the air with a gas meter, makes sure tanks and lines are drained and cleaned, sets safety steps like a fire watch, and signs. Federal welding rules call for the area to be inspected and the work authorized, preferably with a written permit, and industry practice treats the written permit as standard. If nobody can produce a permit after a fire, that fact matters.
Should flame-resistant clothing have protected me? +
That is a fair question, and the answer depends on the work you were doing. Since 2010, OSHA's enforcement position has been that oil and gas workers facing flash-fire danger in drilling, well servicing, and production work should be in flame-resistant clothing. FRs are built to stop burning once the flame passes, instead of staying on fire the way regular clothes do. They cannot make you fireproof, but they often decide how deep and how wide the burns go. If your crew was working in street clothes, somebody made that decision, and it matters to your case.
Who is responsible for an oilfield fire or explosion? +
Often more than one company. It may be the operator, or the contractor doing the hot work. It may be whoever was supposed to issue the permit and test the air. It may be an employer that skipped flame-resistant clothing, or the maker of a part that failed. A Texas law called Chapter 95 can make the claim against the property owner harder, but it does not protect every company on the site. Sorting out that chain of companies is one of the first jobs in any burn case.
What is a burn injury case worth? +
No qualified lawyer can hand you a number at the start, and you should be careful with anyone who does. The honest answer depends on the burns themselves: how deep they go, how far they spread, and how many surgeries are still ahead. It also depends on the scarring, the effect on your work and your family, and which companies are responsible. Serious burn cases are usually valued on the years ahead, not the bills so far. That is exactly why the early insurance offer tends to be low.
Is a fatal burn a wrongful death case? +
It can be. If a worker dies from a fire or explosion caused by a company's careless choices, Texas law may give the surviving spouse, children, and parents a wrongful death claim. What the worker went through before death can support a separate survival claim brought by his estate. These cases run on deadlines, generally two years. The wrongful death guide on this site explains all of it plainly.
