STRUCK-BY HAZARDS

WHEN THE DOOR SWINGS BACK

Struck-By Hazards, the Hidden Catastrophe of Silence,

and Why Reporting Every Incident Saves Lives

THE INCIDENT THAT STARTED THIS CONVERSATION

It began like any other workday. A commercial driver — experienced, professional, trusted — pulled into a third-party scrap facility to unload material. The work was routine. The day was unremarkable. And then, in a fraction of a second, a swinging rear trailer door changed everything.

The heavy door struck him directly in the head. The force of the blow was violent enough to knock him off his feet and send him to the ground. There may have been a brief loss of consciousness. When he came back around, he did what many workers do in that moment: he assessed himself, felt like he was okay, climbed back into his cab, and drove away — resuming his route on public roads as if nothing had happened.

He was alone with that decision. No supervisor was called. No safety manager was notified. No incident report was filed. The driver simply continued his day.

A third-party employee at the facility — someone who did not even work for this company — was the one who recognized the seriousness of what had happened. They contacted management and stated plainly what should have been obvious: a driver who may have just suffered a head injury should not be operating a commercial vehicle on public roads.

The driver was called and brought in. He was evaluated at a hospital. Fortunately — and let us be clear about how fortunate this outcome was — no serious injuries were found. He was medically cleared.

But the story does not end there. The most troubling chapter had not yet been written.

The company’s own Safety Manager learned about this incident not through an official report, not through a supervisor’s call, not through any of the established channels of accountability — but through casual conversation. A comment made in passing. An offhand remark. The kind of thing you hear about a fender-bender in the parking lot, not about a possible traumatic brain injury suffered by an employee operating a 40-ton vehicle on public highways.

Neither the driver. Not the supervisors on duty. Not management. No one reported it.

This is not a story about a swinging trailer door. This is a story about a culture — and the dangerous gap that forms when reporting is treated as optional, burdensome, or something that can wait until later.

UNDERSTANDING STRUCK-BY HAZARDS: THE KILLER HIDING IN PLAIN SIGHT

In the hierarchy of workplace hazards, struck-by incidents occupy a uniquely dangerous position because of how ordinary they feel. Unlike a building collapse or a chemical explosion, most struck-by events happen in the middle of everyday, familiar tasks. They don’t announce themselves. There are no sirens, no warning lights, no dramatic precursors. One moment everything is fine. The next, it isn’t.

The Occupational Safety and Health Administration (OSHA) identifies struck-by hazards as one of the construction industry’s “Fatal Four” — the four leading causes of worker deaths. But make no mistake: struck-by incidents are not confined to construction sites. They occur in warehouses, on loading docks, in scrap yards, in parking lots, and on any worksite where heavy equipment, moving vehicles, swinging doors, falling objects, or pressurized materials are present. They happen to CDL drivers unloading at scrap facilities. They happen to workers who have done the same job hundreds of times before.

Struck-by hazards fall into four broad categories, each presenting its own lethal potential:

• Struck by Flying Objects — Unsecured tools, materials, or components that become projectiles when dropped, launched, or released under pressure. A nail gun misfire. A shattered grinding wheel. A spring-loaded component that releases without warning.
• Struck by Falling Objects — Objects that fall from elevation, shelving, or unstable stacking. A box shifting on a high shelf. A load that was not properly secured. Overhead work that sends debris raining down.
• Struck by Swinging or Shifting Objects — Doors, boom arms, counterweights, suspended loads, and other objects that move through an arc — and through anyone standing in that arc. This is exactly what happened with that trailer door.
• Struck by Vehicles or Mobile Equipment — Forklifts, trucks, backing vehicles, and any motorized equipment operating near pedestrians. In industrial and logistics environments, this is one of the most frequent causes of fatal workplace injuries.

What makes struck-by incidents particularly dangerous is their capacity for deception. A worker who is struck but remains conscious — who can stand up, shake it off, and keep moving — may feel genuinely fine in the immediate aftermath. Adrenaline suppresses pain. The brain’s protective mechanisms engage. The instinct to minimize, to get back to work, to not make a fuss, kicks in hard. And so workers who have just been seriously injured do what our driver did: they get up and drive away.

This is not weakness. It is biology. But it is also why the obligation to report cannot rest with the injured person’s subjective sense of how they feel in the minutes immediately following an incident.

THE SILENT DANGER OF HEAD TRAUMA: WHAT YOU CANNOT SEE

To understand why this incident was so serious — and why the failure to report it was so dangerous — one must understand what can happen inside the human skull when it absorbs a sudden, forceful impact.

Traumatic brain injury, or TBI, does not always look like what people expect. It does not always mean a person is unconscious, bleeding, or visibly distressed. In fact, one of the most dangerous forms of TBI — what medical professionals call a “lucid interval” — involves a person appearing perfectly normal for hours after sustaining a potentially fatal brain bleed. They talk normally. They walk normally. They may insist they are fine. And then their condition deteriorates rapidly, sometimes fatally.

A person who has suffered a concussion or more serious head injury may present as completely normal immediately after the event. The physiological process that causes swelling, bleeding, or neurological damage may not produce visible symptoms for hours — sometimes days — after the initial impact. This is not hypothetical medical theory. This is why emergency medicine protocols require evaluation following any significant head impact, regardless of the patient’s reported symptoms.

Now consider what was happening while that evaluation was being delayed: a man who had just been struck hard enough to fall to the ground and possibly lose consciousness was behind the wheel of a commercial vehicle on public roads. He was making judgment calls, navigating traffic, managing a heavy vehicle — all with a brain that may have been compromised in ways neither he nor anyone else could detect from the outside.

The liability exposure alone is staggering. But the human cost — to the driver himself, to other motorists, to pedestrians — could have been catastrophic. A commercial vehicle accident triggered by an undetected brain injury would not have been just a workplace incident. It would have been a public tragedy.

The only thing standing between that outcome and what actually happened was a third-party employee who had never met this driver before — someone with no obligation, no policy requirement, no personal stake in the matter — who simply saw something wrong and said something. That one person’s decision to speak up may have saved multiple lives.

THE ANATOMY OF A REPORTING FAILURE: HOW IT HAPPENS AND WHY IT MUST STOP

When we examine why this incident went unreported, we are not examining a single person’s failure. We are examining a systemic breakdown — a cascade of missed interventions at every level of the organizational structure.

The driver did not report because he believed he was okay. This is understandable — but it is not his call alone to make. The very nature of head injuries means that the person who has sustained one is among the least qualified to assess its severity. Beyond that, every employee should understand a fundamental truth: reporting an incident is not about how you feel. It is about creating a record, triggering an evaluation, and protecting yourself, your coworkers, and the public.

Supervisors did not report because — we can only speculate — they either were not made aware, did not follow up when they should have, or believed the situation had resolved itself. This is the second failure point, and in some ways the more serious one. Supervisors are the connective tissue of workplace safety. They are the organizational layer most directly positioned to know what is happening in the field and to ensure that incidents are escalated appropriately. When supervisors are absent from the reporting chain, the entire system breaks down.

Management did not report because, apparently, the full picture of what had occurred never reached them through official channels until it was already too late to respond in real time. The Safety Manager — whose entire professional mandate is to know about events exactly like this one — was the last person to find out, and only by accident.

This is the anatomy of a reporting failure. It is not dramatic. It does not involve bad actors with malicious intent. It involves ordinary people making individually understandable decisions that, in aggregate, create an organizational catastrophe.

What could have been triggered by a timely report: immediate medical evaluation for the driver, proper documentation of the incident, a safety review of procedures at the scrap facility, notification to the driver’s family if necessary, compliance with regulatory reporting requirements, and a learning opportunity to prevent the next incident.

What was triggered instead: delayed medical care, an employee operating a commercial vehicle while potentially impaired, a dangerous gap in the company’s incident record, and a Safety Manager who found out through the organizational equivalent of a rumor.

A DIRECT MESSAGE TO LEADERSHIP: THE COST OF CULTURAL SILENCE

If you are reading this as a manager, director, owner, or executive, this section is written specifically for you — because while every employee has a role in safety reporting, the culture that makes reporting possible or impossible is built at the top.

Ask yourself an honest question: In your organization, what happens when someone reports an incident?

If the honest answer involves any of the following — paperwork that seems punitive, questions that feel like interrogations, responses that imply the worker is at fault, outcomes that affect employment status, or simply a culture of “we handle things quietly” — then you have built a system that actively discourages reporting. And you may not know it, because the incidents that are not being reported are, by definition, invisible to you.

The absence of incident reports is not evidence of a safe workplace. It may be evidence of a workplace where people have learned that reporting is not worth the trouble — or worse, that it carries a cost.

The best safety cultures in the world are not the ones with the fewest incidents. They are the ones where every near-miss, every minor injury, every “I almost got hit by that forklift” is documented, analyzed, and used to build a better system. Companies with robust reporting cultures have more incidents on paper — because they are capturing reality. Companies with sparse incident logs often have the same number of incidents; they are simply not recording them.

The incident described in this bulletin could have been a data point in a continuous improvement process. It could have been a case study that identified a hazard at the scrap facility, a gap in driver training on head injury protocols, a need for clearer communication channels between field employees and the Safety Manager. Instead, it became a cautionary tale about what happens when the culture of reporting fails.

Leadership must actively build and protect reporting culture. This means celebrating, not punishing, the act of reporting. It means responding to every report with visible action — even if that action is simply “we reviewed this and the current procedure is sound.” It means ensuring that the Safety Manager is never the last person to hear about an incident. It means creating systems where reporting is easy, fast, and consequence-free for the reporter.

It also means modeling the behavior. When leadership discusses incidents openly, treats them as learning opportunities rather than embarrassments, and holds the organization accountable for reporting rather than outcomes, the message travels throughout every layer of the company: we report everything, always, because that is how we protect each other.

WHAT IMMEDIATE REPORTING PREVENTS: A LEADERSHIP RISK ANALYSIS

For those who think in terms of organizational risk — and every effective leader must — consider the full spectrum of consequences that timely incident reporting prevents. This is not merely a compliance matter. It is a risk management imperative that touches every dimension of your organization’s exposure.

Human Harm Prevention

The most obvious and most important reason to report immediately is that it triggers medical evaluation. In the case of head injuries, every minute without proper assessment is a minute of potential harm going unaddressed. Immediate reporting means immediate evaluation, which means earlier detection of serious injuries that may not be symptomatic yet. In a worst-case scenario, timely reporting saves lives.

Regulatory and Legal Compliance

OSHA regulations require employers to report certain workplace injuries and incidents within specific timeframes. Any hospitalization, amputation, or loss of an eye must be reported to OSHA within 24 hours of the employer learning about it. Beyond federal requirements, many industries and insurance carriers have their own reporting timelines. Failure to report in compliance with these requirements exposes companies to significant fines and legal liability. And critically: “we didn’t know in time” is not a legal defense when the failure to know was itself the organizational failure.

Liability and Litigation Exposure

Unreported incidents create extraordinary litigation risk. If an unreported injury later results in a serious medical condition, the failure to report — and the delay in treatment it caused — becomes evidence of negligence. Plaintiff attorneys in personal injury cases are well-versed in examining incident reporting timelines. The gap between when an incident occurred and when it was first officially documented is not just a compliance failure; it is a liability red flag that can multiply damages significantly.

Commercial Vehicle and Transportation Risk

For any organization operating commercial vehicles, the stakes around driver health and incident reporting are amplified by the additional dimension of public safety. A commercial driver operating under a medical impairment is not just a risk to themselves — they are a potential catastrophic risk to everyone sharing the road. The Federal Motor Carrier Safety Administration regulations around driver fitness are designed precisely to prevent impaired commercial vehicle operation. An organization that allows a driver who may have suffered a head injury to continue driving without evaluation is exposed to federal regulatory action, not just civil liability.

Insurance and Workers Compensation

Late reporting of workplace injuries almost universally creates complications in workers’ compensation claims. Insurers are within their rights to dispute claims that were not reported within required timeframes. Worse, when an injury that went unreported later manifests as a serious medical condition, the injured employee may face challenges establishing the causal connection to the workplace incident — creating a situation where a worker who was genuinely hurt on the job may struggle to receive the benefits they deserve, through no fault of their own.

WHAT EVERY EMPLOYEE MUST KNOW: YOUR ROLE IN THE REPORTING CHAIN

Every person in this organization is part of the safety reporting chain — not just supervisors, not just managers, not just the Safety Manager. Every employee, at every level, has both the right and the responsibility to report incidents and to ensure that incidents get reported.

Here is what that means in practice:

• If you are involved in an incident — no matter how minor it seems — report it immediately to your supervisor and to the Safety Manager. Do not wait to see how you feel. Do not decide on your own that it is not serious enough to report. Report first, assess second.
• If you witness an incident involving a coworker, do not assume someone else is handling it. If you did not see a report being made, it may not have been. Speak up. Check in. Ask if a report has been filed.
• If you have reason to believe a coworker may be impaired — by a head injury, by any other medical concern — do not let them operate equipment or vehicles without clearance. This is not overstepping. This is the highest expression of looking out for a colleague.
• If you see something that creates a struck-by hazard — an unsecured door, a swing radius without proper guarding, objects stored precariously, vehicles moving through pedestrian areas — report it. You do not need to wait for an incident to happen before the hazard is worth addressing.
• If reporting ever feels risky, uncomfortable, or like it might have negative consequences for you — tell the Safety Manager. That conversation itself is important, because a reporting environment that feels unsafe is itself a safety hazard.

The third-party employee at that scrap facility who recognized that a driver with a possible head injury should not be on the road — that person was not the driver’s supervisor, not the company’s safety officer, not anyone with a formal obligation to intervene. They were simply a person who understood what they were seeing and chose to say something.

That is all any of us are ever asked to do.

BUILDING A REPORTING CULTURE: THE LONG WORK OF ORGANIZATIONAL CHANGE

Culture is not a policy. It is not a poster on the breakroom wall or a line in the employee handbook. Culture is the sum of what people actually do when no one is watching, when it is inconvenient, when it feels unnecessary, when the day is already running long and one more report feels like one more burden.

Building a safety reporting culture that works — that captures near-misses and minor incidents before they become fatalities — is the long, unglamorous work of organizational leadership. It does not happen in a single safety meeting. It does not happen because a bulletin like this one was distributed. It happens through consistent, daily demonstration that reporting is valued, that reporters are protected, and that the information gathered through reporting is actually used to make things safer.

Organizations that have achieved strong reporting cultures share several common characteristics. Their leaders discuss incidents openly, including incidents that happened to leadership themselves. They have made reporting frictionless — it takes minutes, not hours. They follow up on every report with a visible response, however brief. They track reporting rates as a positive metric, not a measure of how many problems the company has. And they have established psychological safety around safety: the explicit, demonstrated understanding that no one will face retaliation for reporting an incident, and that the goal of every investigation is learning, not blame.

None of this is revolutionary. All of it is hard. And all of it is worth it.

The cost of building a strong reporting culture — in time, attention, and organizational energy — is a fraction of the cost of a single serious incident that was preventable, that went unreported, and that resulted in a fatality, a catastrophic injury, a regulatory action, or a lawsuit. The return on investment for safety culture is not theoretical. It is documented, repeatedly, across industries and decades of occupational health research.

THE MOMENT BEFORE THE DOOR SWINGS: PREVENTION ALONGSIDE REPORTING

While this bulletin has focused substantially on the imperative of reporting, we would be remiss not to address the other side of the equation: preventing struck-by incidents before they occur.

Trailer doors — like all large, heavy, moving components — present a consistent struck-by risk that is well-understood and well-preventable. Standard best practices when working around trailer doors include:

• Always maintain awareness of swing radius when opening or securing trailer doors. The arc of a fully swinging door can be wider than you expect, particularly in wind.
• Stand clear of the door’s travel path when releasing latches or opening in adverse conditions. Position yourself to the side of the door, not behind it.
• Inspect door hinges, latches, and components regularly. Worn or damaged hardware can cause unexpected and violent door movement.
• At unfamiliar facilities, take a moment to survey the unloading area. Understand what is around you — other vehicles, equipment, personnel — before you begin.
• When wind is a factor, control doors carefully. A door caught by wind can swing with significant force before anyone can react.

More broadly, before any task that involves moving parts, heavy objects, vehicles, or equipment: pause. Identify the struck-by hazard. Think about where you are standing and whether you are in the path of anything that could move. This is not a lengthy process. It is a moment of attention that, practiced consistently, becomes instinct — and that instinct saves lives.

THE STORY THAT MUST NEVER BE TOLD AGAIN

A driver was struck by a door. He got up. He felt okay. He drove away.

That is a story that ends well — this time. Through extraordinary fortune, through the intervention of a stranger, through a medical evaluation that cleared him, the worst did not happen. But the worst was in play. The worst was a realistic outcome for most of the hours between the moment that door hit him and the moment he was cleared by a doctor. Those hours existed because no one reported.

Imagine the other version of this story. The driver, operating on public roads with an undetected brain bleed, loses consciousness at the wheel. A vehicle that weighs tens of thousands of pounds, carrying cargo, traveling at highway speed, with no one in control. The human cost of that outcome is not a statistic. It is families. It is funerals. It is a tragedy that could not be undone by any amount of paperwork filed after the fact.

That version of the story did not happen. But the only reason it did not happen is luck. And safety — real safety, the kind built on culture and accountability and immediate reporting — is not luck. It is the daily, deliberate choice to communicate, to escalate, to never assume that someone else will handle it.

Every person reading this bulletin has the ability, starting today, to make that choice. To be the person who reports. To be the person who ensures their coworker reports. To be the leader who builds a culture where reporting is valued, protected, and expected.

The door swings. The hazard is real. The choice about what happens next is yours.

REPORT EVERY INCIDENT. EVERY TIME. IMMEDIATELY.

Contact your supervisor AND the Safety Manager.

Do not wait. Do not assume someone else will do it.
