Every year, more than 320,000 people die due to an occupational accident. And another 317 million have some form of accident in the workplace. Despite years of increasing investments in safety, and decreasing injury rates because of this effort, the rate of workplace fatalities remains at a plateau. And this plateau is not at zero, where it needs to be (ref: National Safety Council, analysis of OSHA Recordable Rates).
This disconnect - increasing investments in safety leading to diminishing marginal returns - along with the fatality plateau can, and should, be challenged.
