Workplace injuries are costly, not just to employees who may miss work but to businesses that lose the ultimate productivity. That’s the finding of the Liberty Mutual Workplace Safety Index, which found that nonfatal injuries are costing about $60 billion to the workers comp system a year.

The insurer list what it says are the top 10 causes for injury, according to EHS Today. The biggest one is “overexertion” in an outdoor setting, which specifically refers to “lifting, pushing, pulling, holding, carrying or throwing objects.” That cost business nearly $14 billion a year, or 23% of the total cost.

The next leading factors are falls, either to the same level or one below. They account for about $16 billion in cost and 27% of the total burden. Getting struck by an object or equipment comes after that, costing businesses about $4.5 billion and making up 7.4% of the total.

“The remaining five injury causes combined accounted for 19.5 percent of the total direct cost of disabling injuries,” says EHS Today. “These included: roadway incidents involving motorized land vehicle (#6, $3.7 billion); slip or trip without fall (#7, $2.3 billion); caught in/compressed by equipment or objects (#8, $1.95 billion); struck against objects or equipment (#9, $1.94 billion); and repetitive motions involving micro-tasks (#10, $1.81 billion).”

The goal of the study, the insurance company says, is to help businesses and risk managers identify the workplace risks so that they can avoid injury and increase productivity.
