Workplace Head Injury Statistics: What The Data Shows

Quick Answer
Head injuries are among the most serious injuries at work. Traumatic brain injury (TBI) accounts for an estimated 20% to 25% of work-related trauma, and U.S. emergency departments treat more than 50,000 nonfatal work-related TBIs a year on average. Construction has the most fatal and nonfatal work-related TBIs of any industry, with 2,297 fatal intracranial injuries from 2015 to 2022. Falls cause more than half of fatal work-related TBIs, and falling or flying objects cause many of the rest.
Workplace Head Injury Statistics At A Glance
- 20% to 25% of work-related trauma involves a traumatic brain injury (NIOSH).
- 50,000+ nonfatal work-related TBIs treated in U.S. emergency departments each year on average (CPWR).
- 2,297 fatal intracranial injuries in construction from 2015 to 2022 (CPWR).
- 2,210 construction workers died from a TBI between 2003 and 2010. That was 25% of all construction deaths in that period (NIOSH research).
- More than half of fatal work-related TBIs are caused by falls, especially from roofs, ladders, and scaffolds (NIOSH research).
- More than one-third of nonfatal work-related TBIs are caused by falls (CPWR).
- 370 of the 1,032 construction deaths in 2024 were falls, slips, or trips (Bureau of Labor Statistics).
Which Industry Has The Most Head Injuries?
Construction leads every U.S. industry in both fatal and nonfatal work-related TBIs. Construction workers deal with nearly every head injury mechanism in one place: falls from height, falls on the same level, tools and material dropped from above, swinging loads, low beams, and moving equipment. In the 2003 to 2010 NIOSH study, structural iron and steel workers and roofers had the highest fatal TBI rates, and falls caused most of those deaths.
Head injuries are not limited to construction. Warehousing, manufacturing, utilities, oil and gas, and transportation all report head injuries from falls, struck-by incidents, and vehicle crashes.
How Workplace Head Injuries Happen
Falls
Falls are the single biggest cause. They account for more than half of fatal work-related TBIs and more than a third of nonfatal ones. Among workers 55 and older, CPWR reports that most nonfatal work-related TBIs come from same-level falls, meaning slips and trips, not falls from height. A worker who falls can hit their head from any direction, which is why side impact protection matters.
Struck By Objects
Dropped tools, falling materials, and swinging loads are the classic hard hat hazards. A hand tool dropped from several stories hits with enough force to cause serious injury. Overhead hazards are why OSHA requires head protection wherever there is a risk of falling objects.
Struck Against Objects
Bumping into beams, ductwork, pipes, and equipment causes many minor head injuries and some serious ones, especially in tight mechanical spaces.
Vehicles And Equipment
Transportation incidents are the leading cause of workplace deaths overall, and many of those deaths involve head trauma. Roadway work zones combine vehicle and struck-by risks.

Who Is Most At Risk
NIOSH's analysis of fatal construction TBIs found:
- Workers at small companies (fewer than 20 employees) were more than 2.5 times as likely to die from a TBI as workers at companies with 100 or more employees.
- Workers 65 and older were almost 4 times as likely to suffer a fatal TBI as workers 25 to 34.
- Men were 7 times as likely as women to die from a TBI.
- Foreign-born workers had a significantly higher fatal TBI rate than native-born workers.
Small contractors and aging crews deserve the closest attention. They tend to have the fewest safety resources and the highest risk.
The Cost Of A Head Injury
Serious head injuries affect workers and employers long after the incident. NIOSH notes that more severe TBIs can keep a worker from returning to their job and bring long-term rehabilitation and disability costs. One study cited by CPWR found that 43% of hospital patients treated for a TBI were not in ordinary work five years after the injury. Add OSHA penalties, workers' compensation, lost productivity, and the effect on the rest of the crew, and a single serious head injury becomes one of the most expensive events a jobsite can have.
What The Numbers Mean For Head Protection
The data points in one direction. Falls cause the most head injuries, falls hit the head from any angle, and traditional Type I hard hats are designed to protect against blows to the top of the head. That is why OSHA, NIOSH, CPWR, and agencies such as the U.S. Army Corps of Engineers are moving toward Type II safety helmets, which are tested for impacts to the top and sides of the head, with chin straps that keep the helmet on during a fall. CPWR also cites research showing workers who fell while wearing a safety helmet were less likely to suffer head injuries than workers who were not.
Helmets are the last line of defense. The most effective way to reduce head injuries is to prevent falls and dropped objects in the first place with guardrails, covers, housekeeping, tool tethers, and controlled drop zones.

How To Reduce Head Injuries On Your Site
- Prevent falls first. Guardrails, hole covers, and personal fall arrest at the required heights.
- Control slips and trips. Housekeeping, lighting, and footwear matter, especially for older workers.
- Stop dropped objects. Tether tools at height, use toeboards, and barricade drop zones.
- Upgrade head protection. Type II helmets with chin straps for work at height, on ladders, and around moving equipment.
- Inspect and replace helmets. Retire any helmet after an impact.
- Train for concussion symptoms. Make sure crews report head hits and get evaluated.

Frequently Asked Questions About Workplace Head Injuries
Q: How common are head injuries at work?
A: Traumatic brain injury accounts for an estimated 20% to 25% of work-related trauma, and more than 50,000 nonfatal work-related TBIs are treated in U.S. emergency departments each year on average.
Q: What is the leading cause of workplace head injuries?
A: Falls. They cause more than half of fatal work-related TBIs and more than a third of nonfatal ones. Struck-by incidents are the next major cause.
Q: What industry has the most head injuries?
A: Construction has the highest number of both fatal and nonfatal work-related TBIs of any U.S. industry.
Q: Do safety helmets reduce head injuries?
A: Yes. Research cited by CPWR found workers who fell while wearing a safety helmet were less likely to suffer head injuries. Type II helmets add side impact protection, and chin straps keep the helmet on during a fall.
