2022 Workplace Safety Index

2022 Workplace Safety Index

Together.
We can reduce the top 10 causes of disabling workplace injuries.

Today, the top 10 causes of workplace injuries cost U.S. businesses more than $1 billion a week, with total injuries costing more than $58 billion every year. Yet what makes these statistics even more disheartening is that the risk of many workplace injuries can be reduced.

The 2022 Liberty Mutual Workplace Safety Index (WSI) compiles the top 10 causes of the most serious disabling workplace injuries – those that caused employees to miss work for more than five days – ranked by direct cost to employers based on medical and lost-wage expenses.

Back injuries and broken bones can occur on any job, not just high-risk industries such as construction and healthcare. By making business owners aware of how serious injuries happen, we can work together to reduce risk and create a safer workplace for tomorrow.

Study methodology: the annual Liberty Mutual Workplace Safety Index is based on information from Liberty Mutual Insurance, the U.S. Bureau of Labor Statistics (BLS), and the National Academy of Social Insurance (NASI).1 BLS nonfatal injury data are analyzed with the Liberty Mutual data to determine which events caused employees to miss more than five days of work, and then to rank those events by workers compensation costs, which are then scaled to the NASI total cost. To capture accurate injury cost data, each index is based on data three years prior. Accordingly, the 2022 index reflects 2019 data.
