Common Causes of Construction Accidents: Quick Overview

  • Construction sites are high-risk; most accidents are preventable.
  • The Fatal Four, namely falls, struck-by, electrocutions, and caught-in/between accidents, cause most deaths.
  • Some of the key contributing factors include improper equipment setup, limited visibility, complex assembly/dismantling, and unguarded machinery, among others.
  • Injured workers can pursue workers’ compensation and third-party claims.
  • Seek legal support immediately to ensure responsible parties are held accountable, and compensation aligns with your losses.

The “Fatal Four” in Construction Sites

Common Causes of Construction AccidentsAccording to OSHA, the majority of fatal construction accidents are attributed to four primary causes, known as the “Fatal Four.” These hazards persist on job sites despite being well-documented and largely preventable with proper safety measures, training, and employer diligence. These include the following:

  • Falls: This is the leading cause of death in construction. Falls can occur from roofs, scaffolding, ladders, through floor openings, and from any elevated work surface. Incidents often result from a lack of proper fall protection, like guardrails, safety nets, or harnesses, unstable working surfaces, or failure to use equipment correctly.
  • Struck-By Incidents: Construction workers are at risk of being hit by falling tools or materials, swinging construction equipment like backhoes, or vehicles moving around the site. These accidents frequently stem from improper material stacking, lack of toe-boards on scaffolding, or failure to establish clear safety zones.
  • Electrocutions: Contact with live wiring, overhead power lines, or faulty tools and equipment can lead to severe injury or death. Common causes include failure to de-energize circuits before work, using damaged electrical cords, and inadequate grounding.
  • Caught-In/Between Accidents: These gruesome incidents happen when a worker is crushed, pinned, or compressed between objects. Examples include trench collapses, being pulled into unguarded machinery, or getting pinned between a vehicle and a solid object.

Other common construction accidents include:

  • Trench and excavation collapses
  • Machinery and heavy equipment accidents
  • Scaffolding failures
  • Toxic exposure and respiratory injuries
  • Tool and equipment malfunctions
  • Fires and explosions
  • Vehicle and work-zone accidents
  • Ladder accidents
  • Overexertion and heat-related injuries
  • Falling objects

These accidents are mostly preventable, yet they continue to happen because negligence remains alarmingly common on construction sites. When employers cut corners, the risk of a serious or fatal injury rises dramatically.

Contributing Factors To Construction Accidents

A range of other systemic hazards and unsafe practices regularly lead to serious, debilitating injuries on construction sites. These causes often point to failures in planning, communication, ongoing site management, and violation of OSHA regulations.

  • Improper Equipment Setup and Repositioning: Machinery like cranes, scissor lifts, and forklifts pose extreme danger when not set up on stable, level ground or when moved without proper protocols. Frequent, hurried repositioning without new stability checks or hazard assessments is a major risk factor for tip-overs and structural collapses.
  • Limited Visibility and Multiple Operators: Large equipment often has significant blind spots. When multiple pieces of equipment or workers are operating in the same congested area without clear spotters, coordinated signals, or designated pathways, the risk of collision and struck-by incidents skyrockets.
  • Complex Assembly and Frequent Dismantling: Tasks involving temporary structures like scaffolding, shoring, and formwork are highly technical. Errors during assembly—or rushed, improper dismantling—can create catastrophic hidden failures that manifest later, causing collapses that injure multiple workers.
  • Trenching Operations and Unguarded Machinery: Trench collapses are a leading cause of caught-in/between fatalities, often occurring due to a lack of proper sloping, shoring, or shielding. Similarly, the moving parts of saws, grinders, and other machinery must have guards in place to prevent amputations and severe lacerations.
  • Temporary Wiring and Wet Conditions: Construction sites rely on temporary electrical systems, which are vulnerable to damage. When these are exposed to rain, snow, or standing water, the risk of electrocution and shock increases dramatically. Using damaged cords or tools in damp environments is a common but deadly mistake.
