What I have is from 2011 and it is cost based on unintentional injuries at work. It is $188.9 billion dollars in the US only. This does not include the product that is lost. This only includes lost dollars in wage and productivity, medical expenses,administrative expenses,employers uninsured cost,motor vehicle, and fire loss's. These do not include product and warehouse damages which I'm sure would add much more to the final number. A small incident in the warehouse goes a long way further then just that, there are administrative,missed orders and a whole line of issues that will cost your company in the end. ( some data gathered from the National Safety Council report 2011)
