Quick Answer
The Chemical Safety Board released a new video about a 2022 refinery fire that killed two brothers in Ohio. It shows how overwhelmed operators, inadequate safeguards and missed opportunities to stabilize operations contributed to the disaster. The CSB remains active, investigating chemical incidents and recommending changes to prevent similar deaths.
More than 3,700 alarms sounded before a fire killed two brothers at the BP-Husky refinery in Oregon, Ohio. The warnings were there. The systems and decisions needed to bring the refinery to a safe condition fell short.
A new Chemical Safety Board video revisits that disaster and explains why facilities should prepare workers for emergencies before equipment fails or operations spiral out of control. Released Sept. 30, 2026, Alarming Mistakes, Deadly Decisions: Fatal Fire at BP-Husky uses animation and investigator commentary to explain the events leading to the deaths.
The video presents lessons from an earlier investigation: the fire occurred Sept. 20, 2022, and the CSB released its final report on the incident on June 24, 2024. On Oct. 8, 2026, the agency announced that the video had surpassed 500,000 views.
An update to our earlier CSB coverage
Our earlier articles discussed threats to the Chemical Safety Board’s funding. Subsequent posts, including “The Chemical Safety Board is Closing, What Happens Now?” and our article about open investigations left the issue open.
As of Oct. 12, 2026, the CSB continues to publish safety materials and list active investigations, including incidents that occurred in 2026. Its recent releases establish that it remains active.
For injured workers and their families, the distinction matters. The agency continues to provide public information about how chemical disasters happen and what facilities can do to prevent them.
What happened at the BP-Husky refinery?
According to the CSB’s account of the incident, a process disturbance early that morning set off a chain of problems across refinery units. Liquid naphtha eventually entered a pressurized fuel gas mix drum that normally held vapor.
The liquid filled the drum and overflowed into piping serving furnaces and boilers. Workers were directed to drain it quickly. Two employees opened valves and released liquid to the ground. The naphtha vaporized, formed a flammable cloud and ignited near a furnace at approximately 6:46 p.m. Both workers died.
The investigation concluded that the workers may have believed they were draining an amine-water solution rather than flammable naphtha.
SafetyandHealth’s Oct. 9 report describes another major problem: operators faced an alarm flood in the 12 hours before the fire. Thousands of alerts delayed responses and made the worsening conditions harder to manage.
Why planning ahead matters
The CSB’s investigation identified four safety issues: preventing liquid overflow, managing abnormal conditions, handling alarm floods and learning from previous incidents.
A warning that depends on a person responding can become less effective when that person is overwhelmed. Safety+Health reported that a high-level interlock could have automatically stopped the overflow, while the facility relied on alarms requiring human action.
Written emergency procedures also give workers a defined response when normal operating conditions deteriorate. Planning should address when to stop feeding a process, stabilize equipment or shut down, and who has authority to make those decisions.
The 2024 investigation also identified an earlier warning. In 2019, naphtha had begun entering the same vessel after a refinery-wide disturbance. The investigation of that earlier event recognized signs of a possible catastrophic incident but did not develop actions to prevent the vessel from filling again.
The board’s recommendations produced changes. Its investigation page currently lists three recommendations as closed and four as open. One closed recommendation concerns stop-work authority: the refinery’s subsequent owner adopted a procedure and trained employees and contractors. The CSB accepted that action in May 2025.
That follow-through is part of the board’s value. An investigation can identify a failure, and recommendation tracking shows whether the requested changes actually happen.
What does the Chemical Safety Board do?
The U.S. Chemical Safety and Hazard Investigation Board is an independent, nonregulatory federal agency. It investigates serious accidental chemical releases and examines their root causes.
Its investigators include engineers and industrial safety specialists. They interview witnesses, review operating procedures and company safety records, and arrange testing of equipment or chemical samples. Their work looks beyond the immediate equipment failure to examine training, maintenance, operating decisions and safety management.
The CSB publishes reports, produces educational videos and recommends changes to companies, regulators, industry associations and organizations that develop technical standards.
The CSB does not issue fines or citations. Its role differs from regulatory enforcement by OSHA or the EPA. It can examine why a disaster happened even when the problems extend beyond a violation of an existing rule.
Why the CSB matters in personal injury cases
A refinery accident can involve several companies, interconnected equipment and decisions made hours before anyone is injured. Understanding that sequence helps an attorney identify the records, witnesses and technical questions that require independent investigation.
The BP-Husky incident illustrates why that work should extend beyond the last valve a worker opened. A case investigation may need to examine operating conditions, alarm history, instructions given to workers and opportunities to bring equipment to a safe state.
There is an important legal limit. Under 42 U.S.C. § 7412(r)(6)(G), the board’s conclusions, findings and recommendations about an accidental release cannot be admitted as evidence or used in a damages lawsuit arising from matters covered in the report. A CSB report does not establish a company’s civil liability.
Federal regulations also restrict CSB employee testimony, including expert opinions. Attorneys cannot treat agency investigators as a substitute for their own qualified experts.
The practical value is in understanding the safety questions and developing admissible evidence independently. Depending on the incident, that work may include obtaining:
- Control-system and alarm records showing when conditions changed.
- Operating procedures and training records addressing emergency responses.
- Maintenance records and equipment inspections documenting equipment condition.
- Shift logs, emails and witness accounts explaining instructions and decisions.
- Prior incident records and hazard analyses showing what risks the facility had identified.
These are examples of records a legal team may investigate, rather than a statement that every record exists or is admissible in every case. Independent experts can analyze the available evidence, and the court determines what may be presented.
What this means for Houston refinery workers
The same questions matter at facilities in La Porte, Deer Park, Pasadena and Baytown: Were workers given clear instructions? Was hazardous equipment safely isolated? Did the companies involved understand the task and prepare for what could go wrong?
Our earlier refinery coverage discussed the fatal 2021 chemical release at LyondellBasell’s La Porte complex. The CSB found that contractors removing a valve actuator lacked a written procedure and task-specific training. They inadvertently removed pressure-retaining components, releasing an acetic acid mixture that killed two workers.
Although that incident differed from BP-Husky, both investigations examined the conditions in which workers made decisions and performed their tasks.
As we explain in “Who May Be Liable After a Refinery Accident?”, identifying potential responsibility requires examining each company’s role. A company’s presence at a facility alone does not establish liability.
For Texas workers, a personal injury claim may involve a responsible third party. Texas Labor Code § 417.001 allows certain third-party claims alongside workplace benefits. The available claim depends on the worker’s circumstances, the parties’ duties and the evidence connecting their conduct to the injury.
Frequently asked questions
Is the Chemical Safety Board still operating?
Yes. As of Oct. 12, 2026, it has issued recent safety-video releases and continues to list active investigations.
Is this video about a new refinery fire?
No. The video was released in September 2026, but the BP-Husky fire occurred in September 2022. The final investigation report was released in June 2024.
Does the CSB fine companies or decide injury claims?
No. It investigates chemical incidents and recommends safety improvements. It does not issue fines, award damages or decide civil liability.
Can a CSB report prove my personal injury case?
The board’s conclusions, findings and recommendations are subject to a federal statutory bar in related damages lawsuits. A legal team needs to develop admissible evidence and appropriate expert analysis independently.
