Working safe means working in an environment where the probability of accident occurrence is small. Often, this is not small enough. In the Netherlands, approximately 7 million employees work in some 500,000 companies. Every year, 230,000 workers have an accident. This is more than 600 victims a day. One third of these victims are (temporarily) no longer at work due to their accident. Every year, eighty to ninety people die as a result of an occupational accident. That is almost two deaths per week.
