The Human Cost Behind The Case File

Employee 2 had worked at Exxon’s Baytown refinery since 2008. When the hydrodesulfurization unit ruptured and exploded in December 2021, he was a quarter mile away. He and a coworker drove straight toward the fire. He was not on the emergency response team. He suited up anyway, went into the burning unit with Exxon’s firefighters, and helped them find and close valves feeding the blaze.

He made that trip into the fire twice. The first time, he was recovering in an ambulance when he learned a fuel bypass was still open. He suited back up and went back in. Afterward, he sought out Exxon’s own grief counselors, then a licensed social worker, for help with the anxiety that followed. Over the next several months, three separate professionals reached the same conclusion: post-traumatic stress disorder, caused by what he survived that day.

What followed was not treatment. It was a review process: provider after provider, evaluation after evaluation, each new diagnosis met with a company determination that the person who made it was not qualified enough to count. By the time a fourth provider, found through Exxon’s own employee assistance program, confirmed the same diagnosis, Exxon still was not done reviewing it.

Legal Receipts: The Record In Its Own Words

“Once there, though not a member of the facility’s emergency response team, Employee 2 volunteered to enter the burning HDU alongside Exxon firefighters and guide them to several valves which needed to be closed to shut off fuel to the fire.”Fifth Circuit opinion, Exxon Mobil Corp. v. OSHRC, No. 25-60108

• Establishes that Employee 2 was not performing an assigned job duty during the rescue. He volunteered, twice, to walk into an active industrial fire.
• Ties the trauma directly to the workplace, undercutting any later argument that his PTSD diagnosis was unrelated to his job.

“Brown also diagnosed him with a ‘textbook case of PTSD’ and subsequently sent her diagnosis to Exxon via an IDR.”Fifth Circuit opinion, quoting the case record

• A second independent, licensed clinical social worker reached the same diagnosis as the first, in language suggesting the medical picture was not close.
• Exxon still did not treat this as sufficient to record the illness.

“Exxon determined that neither Castillo nor the two LCSWs had ‘appropriate training and experience’… to diagnose recordable work-related mental illnesses.”Fifth Circuit opinion

• Shows Exxon overruling three separate licensed professionals using its own reading of a regulatory qualification standard.
• Exxon, not an independent body, made the initial call on who was “qualified” to diagnose its own employee.

“OSHA exceeded its statutory authority in promulgating 29 C.F.R. § 1904.5(b)(2)(ix) to require employers to record employee-reported work-related mental illnesses.”Fifth Circuit’s holding

• This is the operative outcome: not just Exxon’s $691 penalty erased, but the regulation itself struck down.
• The ruling’s reach extends to every employer previously covered by the mental-illness recording rule, not only Exxon.

The Gray Zone Exxon Used To Make A Diagnosis Disappear

The Occupational Safety and Health Act never defines “illnesses,” and OSHA’s own guidance lets an employer request a second medical opinion when it disputes a diagnosis. Neither piece of the process sets a limit on how far an employer can push it.

• The statute at issue, 29 U.S.C. § 657(c)(2), leaves the word “illnesses” undefined. That ambiguity is what let the Fifth Circuit read the term narrowly and strike the rule requiring mental illness to be recorded at all.
• OSHA’s “second opinion” allowance comes from agency guidance, 66 Fed. Reg. 5916, 5953, not from the statute itself, and it places no cap on how many opinions an employer can solicit or reject before landing on one that supports its position.
• Exxon rejected three licensed providers (two LCSWs and one MD) for lacking “appropriate training and experience,” then accepted a fourth, found through its own employee assistance program.
• Even after accepting that fourth provider as qualified, Exxon still ordered a further review, this time from a doctor of its own choosing, who evaluated Employee 2’s file without ever examining him, since he declined to meet with her.
• Employee 2 argued the fourth provider’s diagnosis already functioned as Exxon’s second opinion. Exxon proceeded with its own designated reviewer anyway, and that reviewer’s records-only opinion is what kept the PTSD off the books.

Who This Actually Hurts

Public Health

• Employee 2 developed PTSD after twice entering a burning industrial unit during the 2021 Baytown emergency response, a diagnosis independently confirmed by four separate licensed providers.
• Two other employees involved in the same emergency response, identified in the case only as Employee 1 and Employee 3, were also diagnosed with PTSD, though the citations tied to their cases were dismissed separately.
• The Fifth Circuit’s ruling vacates 29 C.F.R. § 1904.5(b)(2)(ix) entirely, eliminating the only federal rule requiring any employer to record a worker’s diagnosed, work-related mental illness.
• Without that rule, there is no federal requirement compelling employers to track how often workplace trauma, explosions, fires, violent incidents, produces diagnosed mental illness across their workforce.

Economic Inequality

• Employee 2 needed sign-off from four separate licensed medical professionals to get a PTSD diagnosis that still did not stick. Exxon needed one employer-selected, records-only review to keep it off the official log.
• Exxon’s own medical team routes every reported illness to its risk management and business line staff, who then decide whether it gets recorded. There is no equivalent advocate on the worker’s side of that internal process.
• The dollar amount at stake in this specific citation was $691. Resolving whether it was owed took four years of litigation across three levels of adjudication, resources an individual worker could not match.

The Penalty Was Never Justice

OSHA’s citation carried a $691 fine. The Fifth Circuit erased it entirely, along with the rule that produced it.

• The ALJ’s $691 penalty was vacated in full by the Fifth Circuit, alongside the underlying recordkeeping rule.
• The court’s ruling eliminated the recordkeeping requirement for every employer covered by the rule, meaning future workers with a diagnosed work-related mental illness have no federal mechanism forcing their employer to document it.
• Employee 2 obtained PTSD diagnoses from four separate licensed medical professionals. Exxon needed one records-review opinion from its own designated doctor to keep all four off the official record.

The Cost Of A Worker’s PTSD, Priced In Dollars

This Is The System Working Exactly As Designed

A $691 citation went in one direction and came out having erased a federal safety rule for every employer in the country.

• The dispute began over a single $691 citation and ended with the Fifth Circuit striking the underlying regulation from the books, a result that benefits every OSHA-covered employer, not only Exxon.
• Resolving one $691 citation took from June 2022 to July 2026, over four years, and three layers of adjudication: an administrative law judge, the Occupational Safety and Health Review Commission, and the Fifth Circuit. Those are resources readily available to a company the size of Exxon.
• OSHA’s own guidance let Exxon request a second medical opinion when disputing a diagnosis, but set no limit on how many opinions an employer could solicit or reject first, a gap this case shows can be used to make an inconvenient diagnosis disappear procedurally.
• The court’s decision turned on a narrow legal question: whether OSHA had the statutory authority to write the rule at all. The ALJ had already affirmed the citation itself after a four-day hearing. The fairness of Exxon’s provider-shopping process was never tested on appeal.

What A Legitimate Fix Looks Like

This case exposes a gap between what OSHA believed its recordkeeping mandate covered and what the statute Congress actually wrote, a gap now available to any employer disputing a workplace mental illness diagnosis.

What Now?

This ruling did not resolve one worker’s case quietly. It removed a federal tool for tracking workplace mental illness for every covered employer in the country. Here is where the pressure needs to go.

• OSHA and the U.S. Department of Labor, currently led by Acting Secretary Keith Sonderling, are the agency and office that would need to act, through new rulemaking or supporting legislation, to restore any mental-illness recordkeeping requirement.
• The Occupational Safety and Health Review Commission is the first stop for any future challenge to how this kind of dispute gets resolved.
• Refinery and industrial labor unions, like the one that reported Exxon’s decision to OSHA in this case, are already positioned to track and escalate similar disputes. Support that reporting infrastructure directly.
• Support worker mental health and PTSD peer-support networks for refinery and industrial workers, since the federal recordkeeping backstop for this kind of injury no longer exists.
• Push state-run OSHA-approved safety plans to adopt their own mental-illness recordkeeping requirements, independent of the federal rule the Fifth Circuit just vacated.
