In the United States, injuries (all types) may represent the single most important public health problem. Moreover, estimates of work related fatalities may exceed 10,000 workers per year, while work related disabling injuries number approximately 1.8 million. Approximately 35 million lost work days occur each year due to nonfatal injuries. The direct and indirect costs of occupational injuries is estimated to be 47 billion dollars per year. The outcome of occupational injuries depends not only on the severity of the injury, but also on the rendering of first-aid care. Prompt, properly administered first aid can mean the difference between life and death, rapid vs prolonged recovery, temporary vs permanent disability.
