300 million people in the US and that few fatalities? 14 a day is high or unexpected? There are over 100 fatalities a day in vehicle accidents alone. That is not including accidents at home or from other misadventure. By your stat which is fairly correct, you are closer to ten times more likely to die outside of work then a work place accident.
People make mistakes. At home and at work. I can think of a handful of accidents in my area and everyone if then we’re the result of an employee ignoring a safety rule. The majority of work place accidents I personal have knowledge of were the result of some employee ignoring a safety rule. The larger the company, the more safety was enforced.
