Per the US Department of Labor, Out of 4,674 worker fatalities in private industry in the calendar year 2017, 971 or 20.7% were in construction — that is, one in five worker deaths last year were in construction. The leading causes of private sector worker deaths (excluding highway collisions) in the construction industry were falls, followed by struck by an object, electrocution, and caught-in/between. These "Fatal Four" were responsible for more than half (59.9%) the construction worker, BLS reports. Eliminating the Fatal Four would save 582 workers' lives in America every year.

Following are fatal four categories:

  • Falls (39%)
  • Struck by Object (8.2%)
  • Electrocutions (7.3%)
  • Caught-in/between (5.1%)
