Each day an average of 9,000 U.S. workers sustain disabling injuries on the job, 16 workers die from an injury at work, and 137 workers die from work-related diseases. Data from a study published in 1997 funded by the National Institute for Occupational Safety and Health (NIOSH) showed that in 1992, the economic costs of job-related injuries and illnesses totaled $171 billion. These costs are much higher than those for AIDS and Alzheimer''s Disease and are on a par with those for cancer and circulatory disease. However, there are not enough well-trained occupational safety and health (OS&H) professionals to meet this large burden of disease and injury. The Occupational Safety and Health Act directs NIOSH to fund training programs to educate professionals in the OS&H disciplines (industrial hygiene, occupational health nursing, occupational medicine, and occupational safety). To date, these programs have had a significant public health impact: An average of 700 students graduate annually from NIOSH-supported programs with training in medicine, nursing, industrial hygiene, and safety engineering. NIOSH estimates that about half of all U.S. occupational safety and health professionals graduate from NIOSH-supported programs at the Masters and Doctorate levels. A 1995 report by the Inspector General of the Department of Health and Human Services noted that approximately 80% of the graduates from NIOSH-funded programs pursue careers in OS&H. NIOSH funds more than 1,000 continuing education courses each year with upwards of 30,000 participants.
