What Happened at the Briggsdale Tank Battery Site
On or about October 27, 2018, a contractor was performing work at an oil tank battery site near Briggsdale, Colorado. Briggsdale sits in Weld County, in the heart of the Niobrara/DJ Basin — one of the most active oil and gas production regions in the state. Weld County consistently leads Colorado in oil production, and its tank battery sites are a familiar feature of the landscape. They are also, as federal safety regulators have documented for decades, sites of well-understood and entirely preventable hazards.
The site was operated by Mallard Exploration, a Denver-based oil and gas company. The contractor — a young father with a three-year-old daughter and a family who depends on him — was working on or near a tank that contained residual oil and flammable vapor. At some point during the work, a power tool produced a spark. That spark ignited the vapor inside the tank. The explosion that followed critically injured the contractor, leaving him with burns covering 65% of his total body surface area. He was placed on life support in a medically-induced coma. Two other workers at the site sustained minor injuries.
Mallard Exploration issued a statement acknowledging that sparks from a power tool ignited residual oil and vapor inside the tank, causing the explosion.
Read that admission again. The company that operated the site told the public, in its own words, that a spark-producing power tool was allowed to operate in an atmosphere containing flammable vapor. That single sentence is the foundation of a third-party liability case — because it describes a violation of safety standards so fundamental that every oil and gas operator in the country is required to know and follow them.
Why This Was Not an Accident: The Safety Standards Mallard Exploration Was Required to Follow
The oil and gas industry has known for over a century that flammable vapors accumulate inside and around tanks that contain or have contained petroleum products. The entire regulatory architecture for hazardous area work — federal OSHA standards, the National Electrical Code, industry consensus standards — exists because this hazard is so well recognized that allowing a spark source near it is not a mistake. It is a choice to skip safety steps that the law makes mandatory.
The Hazardous Area Classification: NFPA 70 Article 500
The National Electrical Code, published as NFPA 70, includes Article 500 — a system for classifying locations where flammable gases or vapors are or may be present in sufficient quantities to produce ignitable mixtures. A tank containing residual oil and vapor is the textbook example of a Class I hazardous location. In these classified areas, only electrical equipment that is specifically designed and rated as intrinsically safe or explosion-proof is permitted. A standard power tool — with its motor brushes, switches, and contacts that produce sparks during normal operation — is not intrinsically safe. It is not explosion-proof. It has no place in a classified hazardous atmosphere.
Allowing a standard power tool near a tank containing flammable vapor is not a marginal safety lapse. It is the equivalent of lighting a match in a room you already know is full of gasoline fumes. The classification system exists precisely so that no worker ever has to depend on luck to survive his shift.
OSHA’s Flammable Liquids Standard: 29 CFR 1910.106
OSHA’s standard for flammable and combustible liquids, codified at 29 CFR 1910.106, governs the handling, storage, and processing of flammable liquids in the workplace. It addresses ventilation requirements, ignition source control, and the use of approved equipment in areas where flammable vapors may be present. The standard recognizes what every refinery worker and oilfield operator already knows: flammable liquids produce vapors, those vapors accumulate in confined and semi-confined spaces, and any ignition source — a spark from a tool, a static discharge, a hot surface — can trigger an explosion.
Permit-Required Confined Spaces: 29 CFR 1910.146
If the contractor’s work involved entering the tank — and tank gauging, cleaning, inspection, and maintenance frequently do — then OSHA’s permit-required confined space standard at 29 CFR 1910.146 applies directly. That standard defines a permit-required confined space as one that contains or has the potential to contain a hazardous atmosphere. An oil tank with residual product and vapor is the archetype of such a space.
The standard requires, before any worker enters:
- Atmospheric testing — the air inside the tank must be tested for oxygen content, flammable gases and vapors (using a calibrated gas monitor measuring against the lower explosive limit, or LEL), and toxic contaminants. The atmosphere must be verified as safe before entry and monitored continuously during entry.
- A written entry permit — documenting the hazards, the required controls, the authorized entrants, the attendant stationed outside, and the rescue plan.
- An attendant — someone stationed outside the space whose sole job is to monitor the entrants and initiate rescue if something goes wrong.
- A rescue plan — with properly equipped rescuers available to respond immediately.
If any of these steps was skipped — and the fact that a spark ignited vapor inside the tank strongly suggests that atmospheric testing either did not happen or did not result in the work being stopped — then each omission is a separate violation of federal law.
Lockout/Tagout: 29 CFR 1910.147
Before any maintenance or servicing work on equipment that could unexpectedly energize, start, or release stored energy, OSHA’s lockout/tagout standard requires the isolation of energy sources and the application of physical locks and warning tags. For a tank battery, this means isolating inlet and outlet valves, ensuring no product can flow into the tank while work is being performed, and securing those isolations with physical locks that cannot be removed without the worker’s knowledge.
Hot Work Permits: The Industry Standard Mallard Exploration Should Have Followed
“Hot work” is any work that produces a source of ignition — welding, cutting, grinding, brazing, and the use of spark-producing power tools. The petroleum industry’s own consensus standards, as well as OSHA’s framework, require a hot work permit before any such work is performed in or near areas where flammable vapors may be present. A proper hot work permit system requires:
- Atmospheric testing before work begins, demonstrating that the atmosphere is below the lower explosive limit — meaning there is not enough flammable vapor in the air to ignite.
- Tank purging and venting — removing residual product and ventilating the tank with fresh air or inert gas until the vapor concentration is confirmed safe.
- A designated fire watch — someone whose sole responsibility is to watch for fire during and after the work.
- Verification that all equipment is appropriate for the environment — meaning intrinsically safe or explosion-proof tools where required.
The fact that a spark from a power tool ignited vapor inside the tank tells us that one of two things happened: either no hot work permit was issued, or a permit was issued without the required atmospheric testing and equipment verification. Either way, the safety system that exists to prevent exactly this kind of explosion was either absent or was treated as paperwork rather than a life-safety procedure.
The General Duty Clause: The Catch-All That Never Sleeps
Even if no specific OSHA standard squarely fit this situation — and several clearly do — the Occupational Safety and Health Act’s General Duty Clause provides a floor that no employer can go below:
“Each employer shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees.”
— 29 U.S.C. § 654(a)(1)
The accumulation of flammable vapor in an oil tank is a recognized hazard. It has been recognized for as long as the petroleum industry has existed. The use of spark-producing tools in that atmosphere is a recognized hazard. No employer — and no site operator who controls the premises and authorizes the work — can claim ignorance of a danger the entire industry was built to prevent.
The Medicine of 65% TBSA Burns: What Your Family Is Living Through
When doctors say a burn patient has “65% TBSA,” they mean 65% of the total body surface area is burned. To understand what that number means, you have to understand how burn size is measured — and what it tells you about the road ahead.
How Doctors Measure Burn Size: The Rule of Nines
Emergency physicians use a body-mapping system called the Rule of Nines to estimate the percentage of body surface affected. The head accounts for 9% of the body. Each arm is 9%. Each leg is 18%. The front of the torso is 18%. The back is 18%. The groin is 1%. At 65% TBSA, this man has burns covering roughly two-thirds of his entire body — potentially both legs, one or both arms, and large portions of his torso. This is among the most severe survivable burn classifications in medicine.
The First 24 Hours: Parkland Formula and Burn Shock
When skin is destroyed across this much of the body, the body’s fluid balance collapses. Burn shock — massive fluid loss through the burned surfaces — can kill within hours. Emergency physicians use the Parkland Formula to calculate fluid resuscitation: approximately 4 milliliters of Lactated Ringer’s solution per kilogram of body weight per percentage of TBSA burned, with half of that total volume administered in the first eight hours from the time of the burn — not from the time of arrival at the hospital. For a 70-kilogram person with 65% TBSA burns, that is roughly 18,200 milliliters of fluid — more than four and a half gallons — in the first day alone, with half of it due in the first eight hours.
This is why every minute of delay in transport to a specialized burn center matters. The American Burn Association publishes referral criteria that clearly apply here: partial-thickness burns of 10% or more TBSA, full-thickness burns, burns involving the face, hands, feet, genitalia, or major joints, and any burn with suspected inhalation injury all require burn center referral. At 65% TBSA, this patient met every one of those criteria.
The surgeries: Debridement, Grafting, and the Two-Wound Problem
Full-thickness burns — third-degree burns that destroy the skin all the way through — do not heal on their own. Surgeons must remove the dead tissue (debridement) and transplant healthy skin from an unburned part of the body (a split-thickness skin graft) to cover the wound. But this creates two wounds: the burn site that receives the graft, and the donor site where the skin was harvested. Both are painful. Both are susceptible to infection. Both must heal.
For a 65% TBSA burn, there may not be enough unburned skin to cover all the wounds at once. Surgeons may have to stage the grafting procedures over weeks, covering the most critical areas first and waiting for donor sites to heal before re-harvesting. Some patients receive temporary coverage with biological dressings or synthetic skin substitutes until permanent grafting can be performed.
The Length of Stay: One Day Per Percent
Burn medicine follows a brutal but reliable arithmetic: a seriously burned patient can expect roughly one day in the hospital for every one percent of body surface burned. At 65% TBSA, that means a hospital stay of roughly two months — and the dossier confirms that the expected hospitalization was at least two months, with a projected coma duration of one to two weeks. That hospital stay is only the beginning. After discharge comes months of rehabilitation, physical therapy to recover range of motion in joints stiffened by scar tissue, and potentially years of reconstructive surgeries to release contractures — areas where scar tissue has tightened across joints, restricting movement.
The Cost: Why Workers’ Compensation Will Not Come Close
Initial ICU hospitalization and burn unit care for 65% TBSA burns typically exceeds $2 million to $5 million — and that is just the acute phase. A complete life care plan — which projects every future medical need, every surgery, every piece of equipment, every medication, every therapy session, and every caregiver hour across the patient’s expected remaining lifespan — would likely project total future medical costs in the multiple millions of dollars. A board-certified burn surgeon would testify to medical causation and prognosis. A certified life care planner would build the cost stream. A forensic economist would reduce that cost stream to present value. The number that emerges from that process is the real cost of this injury — and it dwarfs what any workers’ compensation system will pay.
Workers’ compensation pays a capped benefit schedule. It does not pay for pain and suffering. It does not pay for disfigurement. It does not pay for the life the injured person no longer gets to live. That is why the third-party claim — the claim against Mallard Exploration as the site operator whose negligence caused this — is not a luxury. It is the only path to a recovery that comes close to what this family will actually need.
For families facing the catastrophic aftermath of industrial fires and explosions, the same legal and medical principles apply whether the incident happened at a refinery, on a drilling site, or at a tank battery — the duty to control ignition sources in hazardous atmospheres is universal.
Who Is Responsible: The Defendant Map
Mallard Exploration: The Site Owner and Operator
Mallard Exploration controlled the tank battery site. It controlled the tank that contained the residual oil and vapor. It controlled the overall work environment. Its own statement admits that a spark-producing power tool was permitted in a hazardous atmosphere. Under Colorado premises liability law, the site owner/possessor owes a duty to maintain the premises in a reasonably safe condition for workers and contractors. The presence of residual oil and vapor in the tank — a dangerous condition that was known or should have been known to the site operator before authorizing work — is the foundation of that duty.
Mallard Exploration is also subject to ordinary negligence claims for allowing spark-producing power tool work in an environment containing flammable vapor without proper tank purging, atmospheric gas monitoring, hot work permitting, and verification that the atmosphere was below the lower explosive limit. And if Mallard Exploration undertook to direct or supervise the contractor’s work — including the selection of tools, the work sequencing, or the safety procedures — it assumed a duty of reasonable care in that undertaking and may be liable for negligent performance of that undertaking.
The Direct Employer: The Contractor’s Own Company
The injured worker’s direct employer — the contracting company that sent him to the Mallard site — owes workers’ compensation benefits regardless of fault. That is the nature of the workers’ compensation bargain: the employer pays a capped, no-fault benefit, and in exchange, the worker generally cannot sue the employer directly in tort. But if the direct employer directed the use of non-intrinsically-safe equipment, failed to train workers on hazardous area protocols, or failed to conduct pre-work gas monitoring, it may bear additional liability — though the workers’ compensation exclusive remedy bar will typically shield the employer from direct tort claims unless the conduct rises to an intentional tort.
The Power Tool Manufacturer: Products Liability
If the power tool that produced the ignition spark was not rated as intrinsically safe or explosion-proof for use in classified hazardous environments, the manufacturer may face products liability claims for design defect, failure to warn, or marketing defect. A tool designed for general consumer or construction use that lacks adequate warnings about the catastrophic risk of using it in atmospheres containing flammable vapors may be defectively marketed for that environment. This is a separate track that requires identification of the specific tool, its markings and certifications, and its intended use classifications.
Other Subcontractors and Site Contractors
Any additional workers or contractors who contributed to the hazardous condition — by improperly purging the tank, failing to ventilate, failing to conduct atmospheric testing, or failing to communicate the presence of flammable vapor before work commenced — may share comparative liability. On a multi-contractor oilfield site, the responsibility for safety is often divided among several entities, and identifying each one’s role is part of the investigation.
The Workers’ Compensation Fork: Why Comp Is Not Your Only Remedy
Most families in this situation are told, within hours, that workers’ compensation is their only option. That is wrong — or at best, it is half the story.
Workers’ compensation is one lane. It runs against the direct employer. It pays regardless of fault — the worker does not have to prove the employer was negligent. But in exchange, the benefits are capped by a statutory schedule. There is no compensation for pain and suffering. There is no compensation for disfigurement. There is no compensation for the full loss of earning capacity. And the employer is shielded from a direct negligence suit by the exclusive remedy provision of the workers’ compensation act.
The second lane — the one the employer’s insurance company and the site operator’s lawyers hope you never find — is the third-party tort claim. This is a civil negligence claim against a party other than the employer who is responsible for the hazardous condition. Mallard Exploration, as the site owner/operator that controlled the tank and authorized the work, is a third party. A tool manufacturer is a third party. Other contractors who created or failed to address the hazard are third parties.
The third-party lane has no benefit schedule. It pays the full measure of damages — past and future medical care, lost wages, lost earning capacity, pain and suffering, disfigurement, physical impairment, loss of quality of life, and, in cases involving willful and wanton conduct, punitive damages. For a 65% TBSA burn, the difference between the comp lane and the tort lane is not incremental. It is the difference between a capped check that covers a fraction of the medical bills and a recovery that funds a lifetime of care.
If you are navigating a workplace accident where someone other than your employer controlled the site or the equipment, you need to understand this fork — because the insurance adjuster who calls you is counting on you not knowing it exists.
The Statutory Employer Defense: The Central Legal Battle in Colorado
Here is the fight that will likely define this case. In Colorado, the workers’ compensation act includes a statutory employer provision. Under this doctrine, if a contractor’s direct employer does not carry workers’ compensation insurance, the principal — the site owner or general contractor — may step into the shoes of the employer as the “statutory employer.” If that happens, the workers’ compensation exclusive remedy bar could potentially shield Mallard Exploration from the third-party tort claim, leaving the family with only the capped comp benefit.
But there are two critical ways to defeat this defense:
First: If the direct employer maintained its own workers’ compensation coverage. The statutory employer doctrine is primarily designed to protect workers whose direct employers are uninsured — it ensures someone is responsible for comp benefits. If the direct employer carried comp coverage, the statutory employer status may not attach, and the third-party tort claim against Mallard Exploration should remain viable.
Second: If Mallard Exploration’s premises liability and independent negligence are independent of the employment relationship. The statutory employer bar is about the employment relationship — it prevents a worker from suing someone who is, in effect, standing in the employer’s shoes. But premises liability — the duty of a landowner to maintain safe premises — is a duty that runs with the land, not with the employment relationship. A site operator that creates or allows a dangerous condition on its property owes that duty to anyone lawfully on the premises, whether they are an employee, a contractor, or an invitee. This duty is independent of the comp exclusivity bar and should survive the statutory employer defense.
This is the fight that requires a trial lawyer who understands the architecture of the workers’ compensation act, the premises liability doctrine, and how to plead and prove a third-party claim that does not collapse into the comp bar. It is the single most important legal threshold in the case — and it is where a generalist can lose the entire claim before it ever reaches a jury.
Colorado Law: Comparative Fault, Damage Caps, and Punitive Damages
Modified Comparative Negligence: The 50% Bar
Colorado follows a modified comparative negligence standard with a 50% bar. What this means: if the injured worker is found to be 50% or more at fault for the incident, recovery is barred entirely. If the worker is found to be less than 50% at fault, the recovery is reduced by the worker’s percentage of fault. At 30% fault, a $10 million verdict becomes $7 million. At 49% fault, it becomes $5.1 million. At 50%, it becomes zero.
This is why the defense will work tirelessly to pin fault on the injured worker — to argue that he should have known the atmosphere was hazardous, that he should have refused to use the tool, that he should have demanded gas monitoring before starting work. The counter is the regulatory framework: the duty to test the atmosphere, to purge the tank, to issue a hot work permit, and to provide intrinsically safe equipment belonged to the site operator and the employer, not to the individual worker. A worker who is handed a tool and told to do a job is entitled to rely on the safety systems above him — the systems the law requires the operator to maintain.
Non-Economic Damage Caps and the Disfigurement Exception
Colorado imposes statutory caps on non-economic damages in personal injury cases. These caps limit the amount a plaintiff can recover for pain and suffering, emotional distress, loss of enjoyment of life, and other non-economic losses. However, Colorado law provides exceptions to these caps for cases involving substantial physical impairment and disfigurement. Burns covering 65% of the body — producing severe, permanent scarring across most of the skin surface, with associated functional impairment from contractures, skin breakdown, and loss of sensation — are the paradigm case for the disfigurement and substantial physical impairment exceptions. An experienced catastrophic injury attorney will plead and prove the facts that trigger these exceptions, because the difference between a capped and an uncapped non-economic award in a case of this magnitude can be millions of dollars.
Punitive Damages: Willful and Wanton Conduct
Colorado permits punitive (exemplary) damages for willful and wanton conduct — conduct that demonstrates a conscious disregard for the safety of others. Allowing a spark-producing power tool to operate in a tank containing flammable vapor, without atmospheric testing, without a hot work permit, without tank purging, and without verifying that the atmosphere is below the lower explosive limit, is not ordinary negligence. It is the kind of conscious disregard of a known, lethal hazard that supports a punitive damages claim. The exposure of a worker to a recognized, industry-wide, regulated hazard — where the safety steps to prevent it are well established and were simply not followed — is the architecture of willful and wanton conduct. Punitive damages are subject to statutory limitations in Colorado, but they are available, and in a case like this, they should be pursued.
Survival Actions and Wrongful Death
If the injured worker does not survive — and 65% TBSA burns carry a significant mortality risk, particularly in the first weeks after injury — Colorado law provides two distinct frameworks. A survival action, under Colorado’s survival statute, allows the estate to pursue the claim the decedent would have had, including compensation for pre-death pain and suffering, medical expenses, and lost wages during the period between injury and death. A wrongful death action provides a separate recovery framework for designated beneficiaries — typically the spouse and children — for the financial and relational losses they have suffered because of the death. These are distinct claims with different damage components, different beneficiaries, and different procedural requirements. Both must be considered if the family is facing the possibility that the injured worker may not survive. For families confronting this reality, our wrongful death practice handles the specific machinery of death claims in Colorado and nationwide.
The Statute of Limitations: Colorado’s Two-Year Deadline
Colorado imposes a two-year statute of limitations on personal injury claims. The clock starts running on the date of the injury — in this case, October 27, 2018. For wrongful death claims, a separate two-year deadline runs from the date of death. These are hard deadlines. Miss them and the case is over, no matter how strong the evidence or how devastating the harm. But the statute of limitations is not the only clock that matters. The evidence that proves the case has its own, much shorter clocks — and those clocks are already running.
The Evidence Clock: What Exists, Who Holds It, and How Fast It Disappears
This is the section that should create urgency in every family reading it. The legal deadline gives you two years. The evidence deadline gives you days to weeks. Here is every piece of evidence that matters in this case, who holds it, and how fast it can legally die.
The Explosion Scene and Tank Battery Physical Conditions
The tank, its configuration, the presence and extent of residual oil and vapor, the hazardous area classification status, and the overall site safety conditions at the time of the incident are physical evidence. Mallard Exploration controls the site. Site remediation and cleanup — which are necessary for continued operations — can alter or destroy critical physical evidence within days to weeks. The moment cleanup begins, the scene changes. The position of the tank, the condition of its openings, the presence or absence of ventilation equipment, the markings on the power tool, the location of gas monitors (if any existed) — all of this can be altered, moved, or lost. A fire and explosion cause-and-origin expert and a petroleum industry safety expert need to document these conditions before the site is remediated. That documentation requires access to the site, which requires legal action or cooperation from the defendant — which is why a preservation letter has to go out immediately.
The Power Tool That Produced the Ignition Spark
The specific power tool that produced the spark is the single most important piece of physical evidence in the case. It proves the ignition source, and its markings and certifications (or lack thereof) prove whether it was rated for use in a classified hazardous environment. This tool could be discarded, repaired, lost, or replaced within days. A forensic examination by a qualified expert — to identify the tool, document its markings, test its spark-producing characteristics, and determine whether it was intrinsically safe or explosion-proof rated — must happen before the tool is touched, cleaned, repaired, or “misplaced.” A preservation letter demanding that the tool be sequestered and produced is the first step.
Mallard Exploration’s Hot Work Permits, Gas Monitoring Records, and Atmospheric Testing Data
These records prove whether proper hazardous area protocols were followed before authorizing power tool work near the tank — or whether such protocols were absent entirely. If a hot work permit was issued, it should document the atmospheric testing results, the safety measures taken, and the authorization. If no permit was issued, that absence is itself the proof. These records can be altered, retroactively created, or destroyed within days to weeks. A preservation letter demanding that all hot work permits, gas monitoring logs, atmospheric testing data, and safety documentation for the date of the incident and the preceding period be preserved must be sent before these records can be modified or “lost.”
Tank Maintenance, Cleaning, and Purging Records
These records prove whether the tank was properly prepared for work — whether residual oil was removed, whether the tank was ventilated to disperse flammable vapor, and whether the atmosphere was tested and confirmed safe before work commenced. These records may be modified or reconstructed after the incident. They must be demanded within weeks.
OSHA Investigation File
OSHA will investigate this explosion. The investigation may take up to six months to complete, but the file — when it exists — will contain independent expert findings on causation and safety failures, citations for regulatory violations, and the agency’s own reconstruction of what happened. Any citations issued by OSHA are powerful evidence in support of negligence per se theories and punitive damages claims. However, OSHA citations are agency findings, not court judgments — they are contestable before the Occupational Safety and Health Review Commission, and some are later reduced or vacated. They must be monitored and their status confirmed. Early preservation requests and ongoing monitoring of the OSHA investigation are essential.
Witness Statements from the Two Other Injured Workers
The two other workers who sustained minor injuries are critical witnesses. They can describe the sequence of events, the work procedures used, whether safety protocols were observed, and whether gas testing was performed before tool use. Their memories fade rapidly — within days, the accuracy of recall degrades. And witnesses on oilfield sites can be influenced by employers, insurers, or defense counsel who arrive quickly and conduct “interviews” that are designed not to preserve truth but to shape it. Witness statements should be taken by an independent investigator as soon as possible, before memories fade or narratives are managed.
Training Records and Safety Manuals
The injured worker’s employer’s training records and safety manuals prove whether workers were trained on hazardous area work protocols, intrinsically safe equipment requirements, and tank entry procedures. Training records can be fabricated or backdated after an incident — which is why they must be demanded early, with a litigation hold that prevents alteration.
Site Surveillance or Camera Footage
If the tank battery site had any surveillance cameras or if workers were using body cameras or vehicle dash cameras, the footage could provide objective visual evidence of conditions, work practices, and the events leading to the explosion. CCTV systems typically overwrite on a 7-to-30-day cycle. This evidence can be gone within a month — sometimes within days.
What a Preservation Letter Does
A preservation letter — also called a spoliation letter or litigation hold letter — is a formal written demand sent to every party that may hold evidence. It puts them on notice that litigation is anticipated and that they have a legal duty to preserve all relevant evidence. Once a preservation letter is received, the destruction of evidence becomes spoliation — which can trigger court sanctions, adverse inference instructions (telling the jury they may assume the destroyed evidence was unfavorable to the party who destroyed it), and in some jurisdictions, separate claims for the destruction itself. The preservation letter is the single most important pre-suit action in any oilfield explosion case, and it should go out within days of the incident — not months, not after the insurance company has had its turn.
The Insurance Playbook: What the Adjuster Does in the First 72 Hours
Lupe Peña spent years inside a national insurance-defense firm before he joined this firm. He sat in the rooms where adjusters and their software decided how to deny, delay, and devalue people exactly like the families we now represent. He knows the plays because he used to run them. Here is what the insurance machine does in the hours and days after a catastrophic oilfield injury — and here is how each play is countered.
Play 1: The Friendly “Just Checking In” Call
Within days of the explosion, someone will call the family. They will sound warm, concerned, sympathetic. They will say they just want to “check on how he’s doing” and “get a statement for our records.” The call is recorded. Every word the family says will be transcribed and searched for anything that can be used to reduce the claim — a comment about the worker’s prior health, a suggestion that he was experienced and should have known better, an expression of gratitude for the company’s response that can later be framed as satisfaction with the handling of the incident. The counter: do not give a recorded statement. Do not answer questions about the incident, the worker’s health history, or the family’s financial situation. A simple “we are not prepared to give a statement at this time” is enough. The family’s focus should be on the patient, not on building the defense’s file.
Play 2: The Quick Check with a Release Attached
A check may arrive — sometimes within weeks — accompanied by paperwork that includes a release of all claims. The check may look generous in the context of a family that has suddenly lost its income. But a release signed in the first weeks after a catastrophic injury, before the full scope of medical needs, future care, and lost earning capacity is known, is the insurance company’s dream outcome. It closes the file for a fraction of what the case is worth. The counter: do not sign anything without an attorney reviewing it. Any document that uses the word “release” or “settlement” or “full and final” should be reviewed by counsel before a single initial is placed on it.
Play 3: The Company “Investigator” at the Scene
The site operator’s insurance company will have investigators at the scene within hours — sometimes before the fire is fully extinguished. These investigators are not neutral. They are building the defense. They are photographing the scene from angles that minimize the hazardous conditions, taking statements from witnesses in ways that shape the narrative, and documenting anything that can be used to shift blame to the worker. The counter: the family needs its own team at the scene as quickly as possible — a fire and explosion cause-and-origin expert and a petroleum industry safety expert, dispatched under attorney direction, to document the conditions before they are altered.
Play 4: The Social Media and Surveillance Watch
The insurance company will monitor the family’s social media accounts and may conduct physical surveillance. A photo of the injured worker’s family smiling at a hospital bedside can be taken out of context and used to argue the family is not suffering. A post about the worker being “a fighter” can be twisted to suggest he is recovering better than the claim suggests. The counter: set all social media to private. Do not post about the incident, the injuries, the medical condition, or the legal situation. Assume everything is being watched.
Play 5: The Independent Medical Examination with a Doctor the Insurer Picks
The insurance company may demand that the injured worker be examined by a doctor of their choosing — an “independent” medical examiner who is, in reality, a physician selected because of a track record of producing reports that minimize injuries. The counter: any IME should be agreed to only with protections — a recording of the examination, a court reporter, limits on the scope of the examination, and advance notice of the questions to be asked. Never send an injured family member to an insurance doctor without these protections.
For families dealing with workers’ compensation claims alongside a third-party case, the comp adjuster and the liability adjuster are coordinating — even when they pretend they are not.
The Proof Story: How an Oilfield Explosion Case Is Actually Built
Here is the chronological walk of how a case like this moves from the burn unit to a resolution — told by someone who has run it.
Week One: The preservation letters go out — to Mallard Exploration, to the direct employer, to any subcontractors, and to the power tool manufacturer if it can be identified. The letters demand that the explosion scene be preserved, that the power tool be sequestered, that all hot work permits and gas monitoring records be saved, that surveillance footage be retained, and that witness statements not be taken without notice to counsel. A fire and explosion cause-and-origin expert is retained and dispatched to the scene. A petroleum industry safety expert is engaged to evaluate the site’s compliance with hazardous area classification and hot work requirements. The OSHA investigation is monitored and a request for information is filed.
Weeks Two Through Four: The medical records are being generated in real time — and they are the most powerful evidence of harm that will ever exist. The burn unit documentation, the TBSA assessments, the surgical reports from each debridement and grafting procedure, the infection management records, the medication administration logs, the nursing notes documenting the patient’s pain — all of this is being created now, and it must be preserved. A board-certified burn surgeon is identified as a potential expert witness on medical causation and prognosis. The family’s own documentation — photographs, journals, accounts of visits — supplements the medical record.
Months One Through Three: The OSHA investigation file is monitored. Citations, when issued, are obtained and analyzed. The cause-and-origin expert’s preliminary report is reviewed. The safety expert’s analysis of the site’s compliance with OSHA 1910.106, 1910.146, 1910.147, and NFPA 70 Article 500 is developed. The power tool is examined by a forensic expert. The direct employer’s workers’ compensation coverage status is confirmed — a critical fact for defeating the statutory employer defense. Discovery is initiated: Mallard Exploration’s internal safety policies, hazardous area classifications, hot work permit procedures, prior incidents at this and other sites, and OSHA inspection history are targeted.
Months Three Through Six: The medical prognosis stabilizes enough for a life care planner to begin building the future care projection. A forensic economist is engaged to calculate lost wages, lost earning capacity, and the present value of the life care plan. The full scope of the economic loss — past and future medical, past and future lost earnings, household services, vocational impairment — is quantified. The non-economic losses — pain and suffering, disfigurement, physical impairment, loss of quality of life, psychological trauma including PTSD from the explosion — are documented through the medical record, treating provider testimony, and family accounts.
Months Six Through Twelve: Depositions are taken. The site safety director explains under oath how the hazardous area classification was (or was not) performed, how the hot work permit system was (or was not) followed, why atmospheric testing was (or was not) conducted, and who made the decision to allow a spark-producing tool in a flammable atmosphere. The co-workers describe what they saw. The company’s own documents either confirm or contradict the safety story the defense has been telling.
Mediation and Resolution: Mediation should be deferred until the medical prognosis has stabilized and the full scope of future care needs is documented. A case mediated too early — before the life care plan is complete, before the economic loss is fully quantified, before the defense has been forced to confront its own documents in deposition — settles for a fraction of its value. When the case is fully developed, the mediation presents the defense with a choice: pay a number that reflects the full measure of the harm, or face a jury in Weld County that will hear what happened at that tank battery and decide what it is worth.
What This Case Is Worth: Honest Valuation
No honest attorney can promise a specific outcome. Every case turns on its own facts, and the value of any claim depends on the strength of the liability evidence, the severity and permanence of the injuries, the available insurance coverage and defendant assets, the jurisdiction, and dozens of other variables. What we can tell you is the framework within which a case like this is valued.
The case value range for an incident of this nature — a catastrophic 65% TBSA burn caused by a site operator’s admitted failure to control ignition sources in a hazardous atmosphere — falls roughly between $5,000,000 and $25,000,000, depending on how the key variables resolve.
The low end assumes a successful statutory employer defense that reduces or eliminates third-party recovery, significant comparative negligence allocation, and application of Colorado’s non-economic damage caps without successful invocation of the disfigurement/substantial physical impairment exceptions. Even at the low end, the economic damages alone — medical bills, lost wages, future medical care — would likely exceed several million dollars for 65% TBSA burns.
The high end assumes clear third-party liability against Mallard Exploration as premises owner/operator, full economic damages with medical costs alone likely exceeding $3 million to $5 million for burns of this magnitude, maximum non-economic damages with successful invocation of the disfigurement and substantial physical impairment exceptions to the caps, and punitive damages for willful and wanton disregard of fundamental hazardous area safety protocols. The value increases significantly if the injured worker does not survive, given the additional wrongful death recovery available to the family.
Past results depend on the facts of each case and do not guarantee future outcomes. But the framework is real, and the variables that drive the difference between the low end and the high end are the variables a trial lawyer controls — the quality of the evidence preserved, the strength of the liability theory, the effectiveness of the statutory employer defense counter, and the completeness of the damages presentation.
The First 72 Hours: A Practical Roadmap
If you are in the first hours or days after the explosion, here is what to do — and what not to do.
Do:
– Focus on your loved one’s medical care. That is the most important thing. Everything else can wait long enough for you to be present.
– Write down everything you remember about the days leading up to the incident — who was at the site, what work was being done, what equipment was being used, what the worker said about the job. Memory fades fast, and your contemporaneous notes may become evidence.
– Identify and preserve any photographs, text messages, or communications related to the job site, the equipment, or the work being performed.
– Keep every medical record, every hospital document, every bill, every discharge summary. These are the foundation of the damages case.
– Talk to a lawyer. The call is free. The preservation letter can go out the same day you call. The evidence clock is running.
Do Not:
– Do not give a recorded statement to any insurance adjuster — not the employer’s, not the site operator’s, not any third party’s. “We are not prepared to give a statement at this time” is a complete sentence.
– Do not sign any document that contains the word “release,” “settlement,” “full and final,” or “waiver” without having an attorney review it first.
– Do not post about the incident on social media. Set your accounts to private. Assume everything is being monitored.
– Do not let any insurance company investigator examine your loved one, photograph your loved one, or interview your loved one without your attorney’s knowledge and presence.
– Do not wait. The scene is being altered. The tool could be discarded. The records could be modified. The witnesses’ memories are fading. Every day that passes before a preservation letter goes out is a day the defense uses to shape the evidence.
Frequently Asked Questions
Can I sue if my family member was a contractor, not a direct employee of the oil company?
Yes — and this is one of the most important things to understand. Workers’ compensation is the exclusive remedy against the direct employer, but it is not the only remedy against other responsible parties. Mallard Exploration, as the site owner and operator that controlled the tank and the work environment, is a third party. A negligence or premises liability claim against Mallard Exploration is separate from the workers’ compensation claim and is not barred by the comp exclusive remedy provision. This is the fork that the insurance company hopes you never find.
How long do I have to file a claim in Colorado?
Colorado imposes a two-year statute of limitations on personal injury claims, running from the date of the injury. If the injured worker does not survive, a separate two-year deadline for wrongful death claims runs from the date of death. These are hard deadlines — missing them extinguishes the claim entirely. But the evidence that proves the case has much shorter clocks. The preservation letter should go out within days, not months. If you are approaching the deadline, call immediately — there may be options, but only if there is time to act.
What is the statutory employer defense and can it kill my case?
The statutory employer defense is a Colorado legal doctrine that can, in certain circumstances, extend the workers’ compensation exclusive remedy bar to a site owner or general contractor — shielding them from a third-party tort claim. It is the central legal battle in a case like this. But it can be defeated: if the direct employer maintained its own workers’ compensation coverage, the statutory employer status may not attach. And if Mallard Exploration’s premises liability is independent of the employment relationship — which it should be, because the duty to maintain safe premises runs with the land, not with the employment contract — the third-party claim should survive. This is a fight that requires a trial attorney who understands both the workers’ compensation act and the premises liability doctrine.
What if the worker was partly at fault for the explosion?
Colorado follows a modified comparative negligence rule with a 50% bar. If the worker is found to be less than 50% at fault, the recovery is reduced by his percentage of fault but is not eliminated. At 50% or more, recovery is barred. The defense will try to pin fault on the worker — arguing he should have known the atmosphere was hazardous or should have refused to use the tool. The counter is the regulatory framework: the duty to test the atmosphere, purge the tank, issue a hot work permit, and provide intrinsically safe equipment belonged to the site operator and the employer, not to the individual worker.
Can I pursue punitive damages in Colorado?
Yes. Colorado permits exemplary (punitive) damages for willful and wanton conduct — conduct that shows a conscious disregard for the safety of others. Allowing a spark-producing power tool in a tank containing flammable vapor, without the atmospheric testing, hot work permitting, and tank purging that federal safety standards require, is the kind of conscious disregard of a known, lethal hazard that supports a punitive damages claim. Punitive damages are subject to statutory limitations, but they are available and should be pursued in a case like this.
What evidence disappears first in an oilfield explosion case?
The fastest-dying evidence is the physical scene — the tank battery site itself, which can be remediated and altered within days to weeks. Next is the power tool that produced the spark, which could be discarded, repaired, or “lost” within days. Surveillance footage, if any exists, typically overwrites on a 7-to-30-day cycle. Witness memories degrade rapidly — within days, recall accuracy declines. Hot work permits, gas monitoring records, and safety documentation can be altered or retroactively created within days to weeks. The preservation letter is the only thing that freezes these clocks — and it should go out the day you call a lawyer.
What if my loved one does not survive the burn injuries?
If the injured worker does not survive, Colorado provides two distinct legal frameworks. A survival action allows the estate to pursue the claim the decedent would have had — including compensation for the pre-death pain and suffering, medical expenses, and lost wages during the period between injury and death. A wrongful death action provides a separate recovery for the designated beneficiaries — typically the spouse and children — for the financial and relational losses they have suffered because of the death. Both claims must be considered, and both have different damage components, beneficiaries, and procedural requirements. The case value generally increases if the injured worker does not survive, given the wrongful death recovery available to the family.
Should I talk to the insurance adjuster who keeps calling?
No. The insurance adjuster — whether from the employer’s carrier, the site operator’s carrier, or any other party — is not your friend. Their job is to gather information that reduces the value of your claim. A recorded statement given in the first weeks after a catastrophic injury, before you understand the full scope of the harm and before you have legal representation, is one of the most effective tools the insurance company has for devaluing your case. A simple “we are not prepared to give a statement at this time, please contact our attorney” is all you need to say. If you do not yet have an attorney, say “we are not prepared to give a statement at this time” and call one.
How much does it cost to hire an attorney for an oilfield explosion case?
We work on contingency. That means we do not charge an hourly fee. We advance the costs of the case — the expert witnesses, the investigation, the court filing fees, the discovery expenses — and we are paid only if we win. Our fee is 33.33% of the recovery before trial and 40% if the case goes to trial. If we do not recover anything, you do not owe us a fee. The initial consultation is free. This is how catastrophic injury litigation works for families who cannot afford to pay a lawyer by the hour — and it is how we make sure the firm’s interests are aligned with yours: we only win when you win.

If You Are Reading This at 2 A.M.
If you are reading this page in the middle of the night, sitting in a hospital chair or at a kitchen table covered in medical paperwork, here is what we want you to know: what happened at that tank battery near Briggsdale was not an accident. It was a preventable industrial failure. The safety standards that exist to keep spark-producing tools out of flammable atmospheres have been on the books for decades. Mallard Exploration knew or should have known them. The evidence of what went wrong is being altered or destroyed with every passing day. And the insurance adjuster who sounds so friendly on the phone is building a file designed to pay your family as little as possible.
You do not have to face this alone. The call is free. The consultation is confidential. We do not get paid unless we win your case.
Call 1-888-ATTY-911. Or contact us through our website. We will be there.
