The Top 3 Common Causes of Fatal Injuries in Construction

Although the UK is considered one of the safest countries in the world to work, workplace fatalities continue to occur — and construction remains the highest-risk industry. According to the Health and Safety Executive (HSE), construction consistently accounts for around one in four workplace deaths annually. While long-term trends show fatalities declining, the need for vigilance has never been greater. As HSE’s Chief Inspector of Construction recently noted, “Safety must continue to be at the top of everyone’s agenda.” This blog explores the top three leading causes of workplace fatalities in construction and outlines practical measures you can take to prevent them.

1. Falls from Height

Falls from height remain the number one cause of fatal injuries in UK construction, contributing to nearly 30% of all work-related deaths in 2022/2023. These incidents commonly occur on scaffolding, ladders, rooftops, or unfinished structures. Many of these fatalities are preventable with the right planning, training, and control measures.

HSE Guidance — The Hierarchy of Control

  • Avoid working at height where reasonably practicable.
  • Prevent falls by using existing safe platforms or suitable access equipment.
  • Minimise risk and impact if a fall occurs by using the correct fall-arrest or restraint systems.
  • Safe Working Practices

When working at height, you should:

  • Carry out as much work as possible from ground level.
  • Ensure safe access to and from elevated areas.
  • Use stable, well-maintained, and suitable equipment.
  • Take extra care near fragile surfaces.
  • Protect against falling objects and debris.
  • Have emergency and rescue procedures in place.

What to Avoid

  • Overreaching or overloading ladders.
  • Resting ladders on fragile surfaces such as glazing or gutters.
  • Using ladders for prolonged or heavy-duty work.
  • Allowing anyone who isn’t competent or trained to work at height.

2. Being struck by a moving object

The second most common cause of fatal injury in construction is being struck by a moving or falling object — accounting for around 21% of deaths in the 2022/2023 period. These incidents often occur when tools, materials, or debris fall from height, or when equipment is used unsafely.

Prevention Measures

  • Conduct comprehensive, up-to-date risk assessments.
  • Ensure secure storage and lifting procedures for tools and materials.
  • Install exclusion zones beneath elevated work areas.
  • Use safety nets, debris fans, or toe boards where appropriate.
  • Require workers to wear safety helmets at all times.
  • Encourage staff to report near-misses to identify recurring risks.

3. Being Struck by a Moving Vehicle

The third leading cause of workplace fatalities in the UK is being struck by a moving vehicle, responsible for approximately 15% of deaths in the latest HSE report. On construction sites, vehicles such as dumpers, forklifts, and lorries are essential for operations — but without proper controls, they pose significant risk.

Key Risk Factors:

  • Poor visibility or lighting
  • Inadequate segregation of pedestrians and vehicles
  • Lack of traffic management planning
  • Visitors unaware of site rules
  • Fatigue or distraction during vehicle operation

Prevention and Control

  • Conduct a vehicle and traffic risk assessment for every site.
  • Introduce clearly marked pedestrian routes and barriers.
  • Implement speed restrictions and designated parking or loading zones.
  • Schedule high-risk movements (such as lorry unloading) outside of shift changes.
  • Provide visitor inductions covering site rules and required PPE.
  • Establish clear hand signals and radio communication protocols for areas where verbal communication isn’t possible.

By maintaining strong communication and enforcing vehicle safety procedures, construction teams can drastically reduce the likelihood of fatal incidents.

Summary

Every worker deserves to go home safely at the end of the day. By recognising and actively addressing these three leading causes of construction fatalities — falls from height, struck-by-object incidents, and vehicle collisions — the industry can continue moving towards zero harm. At Eryri Consulting, we believe that safety is not just compliance — it’s culture. Through proper training, planning, and the right documentation, your team can operate confidently and safely.
