In 2020, struck-by hazards were the 2nd leading cause of worker deaths on construction sites. This month, we’ll be sharing resources to help construction crews provide ongoing training and reminders to prevent struck-by hazards on the jobsite.



The Focus Four Hazards have accounted for the vast majority of injuries and fatalities in the construction industry. In an effort to prevent future injuries and fatalities, OSHA, our state plans, consultation projects, and construction industry partners have initiated a “Focus Four Hazards” campaign from March through June in Region Three’s jurisdiction.  The goal of this campaign is to raise awareness in the recognition, evaluation, and control of these hazards through the delivery of toolbox talks for employers to provide to their workers. These toolbox talks will be available during the campaign for employers to use at their own discretion.

Construction’s “Fatal Four”

Out of 4764* worker fatalities in all industries in calendar year 2020, 1,008 or 21% were in construction―that is, one in five worker deaths last year were in construction. The leading causes of worker deaths on construction sites were falls, followed by struck-by, electrocution, and caught-in/between. These “Fatal Four” hazards were responsible for more than half (57%) of the construction worker deaths in 2020*, according to BLS reports.

  • Falls – 368 out of 1,008 total deaths in construction in CY 2020 (~37%)
  • Struck by Object – 83 (8%)
  • Electrocutions – 53 (5%)
  • Caught-in/between – 70 (~7%) This category includes construction workers killed when caught-in or compressed by equipment or objects, and struck, caught, or crushed in collapsing structure, equipment, or material.


Eliminating these four hazards would save 574 lives each year.

We ask that you assist us in promoting this campaign with your construction contacts and encourage your leadership to participate in these efforts to prevent future injuries and fatalities. To receive these toolbox talks, you can contact our Area Offices, Consultation Projects, or send us an email request at

We appreciate your assistance and support with this campaign.  We encourage you to provide feedback which will assist us in promoting future efforts and evaluating our impact in the construction industry. All voluntary feedback may be sent to OSHA’s designated Focus 4 campaign account at We thank you for your part in bringing awareness to these preventable incidents.

Each week, we will be featuring a toolbox talk on struck-by hazards, or how to avoid and prevent struck-by incidents. Check out the GBCA Toolbox Talk Toolkit to see the latest featured talks!
