Each June, we celebrate National Safety Month, a good time to step back and view the big picture of safety concerns. The 2016 Liberty Mutual Workplace Safety Index, shown below, outlines the causes and costs of US workplace injuries. While it shows the leading issue to be overexertion, slips, trips and falls are split into three categories. When combined, these injuries account for 28.9% of the total and $17.92 billion – clearly #1 in both cause and cost.
