California's Division of Occupational Health and Safety, more commonly known as Cal/OSHA, is charged with enforcing California state laws regarding workplace safety. As part of this process, Cal/OSHA collects annual data on reported workplace fatalities. The graphs above, built using preliminary data for 2008, show that men and professional drivers suffer the most deaths in the workplace. It may be interesting to note that behind traffic accidents, assaults and violent acts represent the second most common cause of death, significantly higher than other accidental causes, such as falls or exposure to substances.
