Liberty Mutual Safety Index 2011
1 like806 views
The 2011 Liberty Mutual Workplace Safety Index identifies the top causes of disabling non-fatal workplace injuries in 2009 based on workers compensation insurance claims. The most costly injuries were overexertion, falls on the same level, and falls to a lower level, together accounting for over 70% of the $50.1 billion total costs. While overall costs decreased 6.5% from 2008, costs for some injury types like falls increased substantially over the period from 1998-2009.

Bodily reaction, which includes injuries resulting from free bodily motion such as bending, climbing, reaching, standing, sitting, and slipping or tripping without falling, ranked fourth at $5.28 billion. Struck by object took the fifth- place ranking at $4.64 billion. Remaining Injury Causes The remaining five injury causes in the top 10 each accounted for less than 5.0 percent of the direct cost of disabling injuries in 2009. Highway incident represented 4.3 percent of the total injury burden at $2.18 billion; caught in/compressed by (injuries resulting from workers being caught in or compressed by equipment or objects) accounted for 4.1 percent of the total injury bur- den at $2.04 billion; struck against object accounted for 4.0 percent at $2.01 billion; repetitive motion, with related injuries, accounted for 3.9 percent of the cost burden at $1.97 billion; and assault/violent act accounted for 1.2 percent at $0.59 billion.
