Occupational health and safety

Occupational health and safety is the field of public health that studies trends in illnesses and injuries in the worker population and proposes and implements strategies and regulations to prevent them. Its scope is broad, encompassing a wide variety of disciplines—from toxicology and epidemiology to ergonomics and violence prevention.3 Historically, the focus of occupational health and safety efforts have been on manual labor occupations, such as factory workers.
But the field now encompasses all occupations in the United States. In addition to ensuring our work environments (from construction sites to office buildings) have safety precautions in place to prevent injuries, experts in occupational health also work to limit both short-term and long-term hazards that could lead to physical or mental illness now or in the future.
