Construction is one of the most dangerous jobs in the country. Scaffolding, cranes, live electrical systems, trenches, and heavy machinery are all part of a normal day on a job site, and any one of them can turn deadly in an instant. Federal workplace-safety regulators have identified four hazard categories that account for the majority of construction worker deaths nationwide. Safety professionals call them the "fatal four."
If you were hurt, or you lost a family member, in one of these four types of construction accidents in the Vancouver, Washington or Portland, Oregon area, you probably already know that workers' compensation is only part of the picture. It pays some of your medical bills and a portion of your lost wages, but it does not come close to covering everything a serious injury costs you, and in most cases it bars you from suing your own employer. What many injured workers don't realize is that someone other than their employer is often legally responsible for what happened, and pursuing that person or company is frequently the only way to recover full compensation.
This guide explains the fatal four, who typically causes them, and how a third-party injury claim works alongside your workers' comp benefits.
What Are OSHA's "Fatal Four" Construction Hazards?
The Occupational Safety and Health Administration (OSHA) groups the leading causes of construction fatalities into four categories. Federal workplace-safety data consistently show these four hazards responsible for the large majority of on-the-job construction deaths each year.
1. Falls
Falls from roofs, scaffolding, ladders, and unprotected floor or wall openings are the single leading cause of death on construction sites. Federal fall-protection regulations require employers to protect workers from a fall as soon as they're working 6 feet or more above a lower level. Depending on the task, that protection has to come from a guardrail system, a safety net system, or a personal fall arrest system such as a harness and lanyard. The regulations also require covers or guardrails around floor holes and skylights, protection at the edges of excavations, and toeboards or barricades to keep tools and materials from falling on workers below.
When a fall happens because a guardrail was missing, a harness anchor point failed, scaffolding was improperly built, or a hole was left uncovered, that is rarely bad luck. It is usually a violation of a specific, well-established safety standard.
2. Struck-By Incidents
Struck-by injuries happen when a worker is hit by a moving object: a swinging crane load, a reversing dump truck, falling debris, or material ejected from a nail gun or power tool. These injuries are especially common on sites where heavy equipment and foot traffic share the same space without adequate separation, warning systems, or spotters.
3. Electrocutions
Live power lines, exposed wiring, damaged extension cords, and improperly grounded equipment all create electrocution risk on a job site, and the danger multiplies in wet conditions. An electrocution can cause immediate cardiac arrest, severe burns, or a fall from height triggered by the shock itself.
4. Caught-In or Caught-Between
This category covers workers who are crushed, pinned, or compressed between two objects, or between moving parts of a single object. Trench collapses, being caught between a vehicle and a fixed structure, and getting pulled into unguarded machinery are all common examples. Caught-in/-between hazards are especially deadly because the crushing forces involved often cause internal injuries that aren't immediately obvious.
Who Is Responsible for Keeping a Job Site Safe?
Washington's workplace-safety law requires every employer to furnish a workplace "free from recognized hazards that are causing or likely to cause serious injury or death" and to comply with the safety standards adopted under that law. On a construction site, that duty doesn't rest on just one company. A general contractor, the subcontractors it hires, equipment rental companies, and the property owner can all share responsibility for site conditions depending on who controlled what, and who created or failed to fix a hazard.
That layered structure is exactly why construction accidents so often involve more than one at-fault party, and it's the key to understanding your legal options after a serious injury.
Can I Sue My Employer After a Construction Accident?
In most cases, no. Washington's industrial insurance law, commonly called workers' compensation, was built to replace lawsuits against employers with a no-fault benefits system. In exchange for guaranteed, faster medical and wage-replacement benefits regardless of who was at fault, injured workers generally give up the right to sue their own employer in court. There is a narrow exception if an employer deliberately intended to injure a worker, but that exception rarely applies to a safety failure or a negligent job site, even a seriously negligent one.
This trade-off means workers' comp benefits, while valuable, are limited. They typically cover a portion of your medical treatment and a percentage of your lost wages, but they do not pay for pain and suffering, and they often fall short of covering the full cost of a serious, long-term injury.
What Is a Third-Party Claim, and Why Does It Matter?
This is where most injured construction workers leave real compensation on the table. While you generally can't sue your own employer, Washington law specifically allows an injured worker to pursue a separate claim against a "third person" whose negligence caused the injury, meaning anyone other than your direct employer. If you win or settle that claim, you can recover the full range of damages a workers' comp claim doesn't cover, including pain and suffering, on top of the benefits you've already received.
On a construction site, potential third parties include:
- The general contractor, if you were employed by a subcontractor and the GC controlled site safety or created the hazard.
- A different subcontractor whose crew's work, equipment, or negligence caused your injury, even though you don't work for them.
- The property owner, if a dangerous condition on the property caused the accident.
- An equipment or tool manufacturer, if defective machinery, a faulty nail gun, or a failed harness component caused your injury. These claims can proceed under product liability law even when workplace negligence also played a role.
- An architect or engineer, in cases where a design defect contributed to a structural failure.
Because most construction sites involve a web of contractors and subcontractors working around each other, identifying every responsible party often takes a real investigation: site logs, subcontractor agreements, equipment maintenance records, and witness statements. This is exactly the kind of work an experienced construction accident attorney does before a claim is ever filed.
How Workers' Comp and a Third-Party Claim Work Together
You don't have to choose one or the other. If you have a viable third-party claim, Washington law lets you pursue it while your workers' comp benefits continue. There are procedural steps involved, including notifying the Department of Labor & Industries or your employer's self-insurer when you file a third-party lawsuit, because they typically have a statutory interest in part of the recovery to offset benefits already paid. An attorney handles this coordination so you don't have to manage two systems at once, and so nothing you do in one claim jeopardizes the other.
What Should You Do After a Fatal Four Construction Accident?
- Get medical care immediately, even if you think you can push through. Some crush injuries, electrical injuries, and head injuries from falls don't show their full severity right away.
- Report the incident to your employer and confirm it's documented, which starts your workers' comp claim.
- Preserve evidence if you're able to: photos of the site, the equipment involved, and any missing safety gear. If you can't do this yourself, ask a coworker, family member, or your attorney to do it before conditions change.
- Don't sign anything from an insurance company, especially a general release, before you understand what it covers. A release for one company's insurer does not need to end your case against a different responsible party.
- Talk to a construction accident attorney early. Evidence at a job site disappears fast, equipment gets moved or repaired, and witnesses change jobs. The sooner an investigation starts, the more evidence there is to work with.
If your loved one was killed in a construction accident, this same third-party framework often applies to a wrongful death claim, and the same urgency around evidence and deadlines applies as well.
Frequently Asked Questions
If I already filed for workers' comp, can I still sue someone else? Yes. Workers' compensation and a third-party injury claim are separate systems, and Washington law is written specifically to allow both. Filing for workers' comp doesn't waive your right to pursue the party who actually caused the accident, as long as that party isn't your direct employer.
What if I was partly at fault for the accident? Yes, you can generally still recover. Washington uses a pure comparative fault system, so your damages are reduced by your percentage of responsibility rather than wiped out by it. Being partly at fault does not disqualify a claim.
Does it matter if I was an independent contractor instead of an employee? It can. Whether workers' comp covers you, and what other legal options might be available, depends on your actual employment classification and the specific facts of how you were hired and supervised, not just the label on a contract. Independent contractor status can sometimes open up direct negligence claims against the hiring company that wouldn't otherwise be available to an employee, but that depends entirely on your situation. A lawyer can assess your classification early and explain what it means for your case.
How long do I have to file a claim? Deadlines differ for workers' comp claims and third-party civil claims, and missing either one can permanently close off your options. Don't wait to find out which applies to your situation.
What if OSHA cited the contractor after my accident? An OSHA citation isn't the same as a personal injury verdict, but it can be powerful evidence that a specific safety standard was violated and that the hazard was known. It's one of the first things an attorney will request when investigating a claim.
