The most disabling workplace injuries

Each year, Liberty Mutual Insurance’s Research Institute for Safety issues its Workplace Safety Index which identifies the top causes of serious, non-fatal workplace injuries based on information from Liberty Mutual workers compensation insurance claims, the U.S. Bureau of Labor Statistics (BLS) and the National Academy of Social Insurance.

Using injury-event definitions developed by the BLS, Liberty Mutual researchers examine injury data to determine which events caused an employee to miss six or more days of work and then ranked those events by total workers compensation costs.

Liberty Mutual is a diversified global insurer and one of the  largest property and casualty insurers in the U.S.

The 2013 Workplace Safety Index provides statistics for injuries that occurred in 2011, the most recent year for which data are available.
