What is Heinrich's ratio of no injury accidents to minor injuries, to major injuries?

Heinrich's ratio, often referred to as the "Heinrich Pyramid," is a foundational concept in the field of safety management that illustrates the relationship between the different levels of accidents. The correct ratio in this context is 300-29-1, which indicates that for every one major injury, there are approximately 29 minor injuries and 300 no-injury incidents that occur.

This ratio emphasizes the idea that minor incidents are significantly more frequent than major accidents, a principle that can be leveraged for injury prevention strategies. By focusing on reducing minor injuries, organizations can effectively decrease the likelihood of more severe incidents occurring. Heinrich proposed this ratio as a way to highlight the need for proactive safety measures at lower levels of injury incidence to create a more comprehensive safety culture.

In this understanding, the other ratios presented do not accurately reflect the established Heinrich's Pyramid, making the 300-29-1 ratio the correct representation of Heinrich's findings regarding workplace accidents and injuries.
