Annual Study Identifies the Causes and Costs of the most Serious Workplace Injuries Across the Economy and for Specific Industries

The findings of the latest Liberty Mutual Workplace Safety Index can help companies restarting and adapting operations better manage and mitigate risk by focusing efforts to improve safety on the leading causes of the most serious workplace accidents, those causing an employee to miss more than five days from work.

“Improving safety is critical to better protecting workers and companies’ bottom-lines,” said Liberty Mutual National Insurance Risk Control Vice President and General Manager James Merendino. “Effectively doing so requires employers – working with their brokers and insurers – to focus on the causes of the most serious injuries. By delivering this information, the Workplace Safety Index can play a key role in guiding these efforts at this critical time.”

The ten most costly causes of workplace injuries and illnesses according to the 2020 Liberty Mutual Workplace Safety Index can be seen here.

  • Overexertion and Falls on same level have been the consistent top two injury causes
