The Fatal Four is a set of the most common fatal accidents in the construction industry. According to OSHA data, if these accidents were prevented, over half of construction-related fatalities would be prevented in the United States. In 2018, this would have meant that 591 lives would have been saved had these hazards been prevented as they should’ve been. Construction’s “Fatal Four" are: falls, struck by swinging, flying, or falling objects, electrocution, and caught-in/between accidents.
