Construction work helps build roads, homes, schools, and hospitals. With this crucial work, comes serious risks. OSHA warns that four types of hazards cause a large share of deadly construction accidents: falls, struck-by incidents, caught-in or -between incidents, and electrocutions.
OSHA calls these the “Fatal Four.” These injuries have caused most construction-related deaths, and OSHA’s QuickCard lists those same four categories as the top four causes of construction fatalities.
This guide explains what the Fatal Four are, why they matter, and what workers and families should know about these deadly construction hazards.
What Are the OSHA Fatal Four?
For workers, the Fatal Four are not just safety terms. They describe the kinds of events that can change a life in seconds. For families, they help explain how many job site deaths happen and why safety rules matter so much. When a worker is badly hurt or killed on a construction site, the impact can reach every part of a family’s life, from income and medical care to grief and long-term uncertainty.
The OSHA Fatal Four are:
- Falls
- Struck-by incidents
- Caught-in or -between incidents
- Electrocutions
The problem is still serious today. According to the U.S. Bureau of Labor Statistics, the construction industry had 1,075 fatal work injuries in 2023, the highest total for that sector since 2011. In that same year, falls, slips, and trips accounted for 421 construction deaths, or 39.2% of all construction fatalities.
That number helps show why the Fatal Four matter. Falls alone remain a major danger, but workers also face deadly risks from moving equipment, collapsing materials, trench hazards, live wires, and unsafe machinery. Understanding each category can help workers recognize danger sooner and help families better understand what may have gone wrong after a serious incident.
Why the Fatal Four Matter in Construction
Construction sites change fast. A safe area in the morning may become a minefield by the afternoon. New crews arrive. Heavy equipment moves in and out. Openings and manholes are uncovered. Power lines may be closer than they look. Trenches can shift. Loads can swing overhead.
OSHA describes construction as a “high hazard industry” and notes that workers may be exposed to serious dangers such as falls from rooftops, being struck by heavy equipment, and electrocutions. One out of every five workplace fatalities is a construction worker, so caution is essential in this profession.
That is one reason the Fatal Four get so much attention. These hazards are common, deadly, and often preventable with better planning, training, supervision, and job site controls. When those protections break down, workers and their families can pay the price.
Falls: The Leading Fatal Four Hazard
Falls are widely recognized as the leading cause of death in construction. OSHA’s QuickCard lists falls first among the top four construction hazards, and BLS reported 421 fatal falls, slips, and trips in construction in 2023.
A fall hazard can involve:
- Unprotected roof edges
- Unsafe ladders
- Improper scaffolding
- Floor openings
- Missing guardrails
- Weak or unsecured walking surfaces
Some falls happen from great heights, but not all do. BLS reported that, in 2023, many fatal falls to a lower level in construction happened from heights between 6 and 30 feet.
While some workers may assume a shorter fall is less dangerous, a fall from a ladder, scaffold, platform, or partially built structure can still be deadly. Head injuries, spinal cord damage, internal injuries, and other catastrophic harm can happen in an instant.
Struck-By Incidents: When Objects, Vehicles, or Equipment Hit a Worker
A struck-by incident happens when a worker is hit by a moving object, vehicle, tool, or piece of equipment. These incidents may involve:
- A vehicle backing into a worker
- A falling tool or load
- Equipment swinging into someone nearby
- Materials dropping from above
- A worker being hit by moving machinery
Struck-by incidents are especially dangerous on busy job sites where many trades are working at once. Noise, blind spots, tight spaces, poor communication, and rushed schedules can all increase the risk. Something as simple as standing in the wrong place at the wrong time can lead to a devastating injury.
These accidents can be devastating to those involved, and can have a life-long impact on the victim and their family.
Caught-In or -Between Hazards: Crushing and Compression Dangers
Caught-in or -between incidents happen when a worker is squeezed, crushed, pinched, or compressed between objects. These events can be deadly and are often tied to machinery, collapsing materials, trench hazards, and moving equipment.
Common examples can include a worker being:
- Pinned between a vehicle and a wall
- Pulled into unguarded machinery
- Trapped in a trench collapse
- Crushed by shifting materials
- Caught between heavy equipment and a fixed object
These incidents are often violent and sudden. A worker may have little or no time to react. In trench or excavation cases, the collapse itself may happen without warning. In machinery cases, missing guards, poor lockout procedures, or unsafe maintenance practices can turn routine work into a fatal event.
One reason this hazard is so serious is that it can affect breathing, circulation, and major organs within seconds. Even when a worker survives, the injuries may be life-changing.
Electrocutions: Hidden and Deadly Job Site Risks
Electrocution is another major Fatal Four category. Electrocutions are among the top four causes of construction fatalities, as workers may be exposed to electrical hazards throughout the course of normal job site activity.
Electrocution risks can involve:
- Contact with overhead power lines
- Exposed wiring
- Improper grounding
- Damaged extension cords
- Unsafe use of power tools
- Live circuits during construction or repair work
Electrical injuries may cause burns, heart damage, nerve injuries, falls from height, and death. What makes electrocution especially dangerous is that the hazard may not be obvious. A live wire may not look different from a safe one. Moisture, metal surfaces, and damaged protective equipment can also raise the risk.
Workers’ Compensation in Virginia After a Fatal Four Accident
In Virginia, many injured workers must begin with a workers’ compensation claim. The Virginia Workers’ Compensation Act governs that system, and the Virginia Workers’ Compensation Commission provides claim forms, filing information, and guidance for injured workers.
Workers’ compensation can be very important after a serious workplace injury because it may provide access to medical benefits and wage-related benefits without requiring the worker to prove a traditional negligence case against the employer. But it also has limits. In many covered cases, this may be a victim’s only legal recourse against the employer.
This is why prompt reporting to the proper departments is critical. Some workers think that reporting the accident to a supervisor is enough, but it may not be. Virginia law separately requires notice of the accident and filing of the claim, so be aware of these steps if you or a loved one is injured on the job.
When a Workplace Accident May Also Lead to a Personal Injury Lawsuit
One of the biggest legal issues in Fatal Four cases is whether there is a third-party claim in addition to workers’ compensation.
That question often comes up when the injured worker’s direct employer did not create the hazard. A worker may be hurt by:
- Another contractor’s vehicle
- A defective ladder, scaffold, harness, or tool
- Unsafe work performed by an outside company
- A negligent driver in a work-zone crash
- Dangerous property conditions created by someone other than the employer
In cases like those, a separate personal injury lawsuit may be possible against the third party, while workers’ compensation may still apply through the employer relationship. Virginia’s third-party recovery statute addresses that situation and gives the employer certain rights tied to the worker’s recovery.
This is one reason Fatal Four cases can become legally complex very fast. A family may be dealing with medical treatment, missed work, disability questions, multiple insurance carriers, and more than one potential defendant.
Wrongful Death Claims After a Fatal Construction Accident in Virginia
When a Fatal Four accident takes a worker’s life, the case may involve wrongful death issues as well as workers’ compensation death benefits.
Virginia’s wrongful death statute sets the time limits for wrongful death actions. In general, a wrongful death action must be brought within a two-year limitations period. Virginia also generally gives two years for personal injury actions, unless another statute applies.
In a fatal construction case, the legal path may depend on who caused the death. If the death is covered by workers’ compensation and involves the employer, that system may control the claim against the employer. If a third party caused or contributed to the death, a wrongful death lawsuit may also be possible depending on the facts.
Why Legal Timing Matters After a Fatal Four Injury
After a catastrophic workplace accident, families are often overwhelmed. They are trying to get medical answers, talk to employers, manage bills, and understand what happened. In that kind of moment, legal deadlines can be easy to overlook.
But deadlines matter. A delay can affect evidence too. Job site conditions can change quickly. Equipment can be moved. Witness memories can fade. Contractors may point fingers at each other. In serious Fatal Four cases, understanding the legal framework early can make a major difference in how a claim is investigated and pursued.
How Fatal Four Accidents Affect Families Beyond the Job Site
A Fatal Four accident does not stop at the construction gate. A fall, crush injury, struck-by impact, or electrocution can affect every part of a family’s life. There may be emergency surgery, rehabilitation, lost income, long-term disability, and sudden caregiving needs. In fatal cases, families may be left without the person they depended on most.
That is why these cases are about more than paperwork. They are about accountability, financial stability, and getting clear answers after a traumatic event. Whether a claim involves workers’ compensation, a third-party injury lawsuit, a wrongful death claim, or some combination of the three, the legal issues are often complex and draining.
