Which organization works to prevent workplace injuries and promote worker safety?

The Occupational Safety and Health Administration (OSHA) is the organization specifically designated to ensure safe and healthy working conditions by setting and enforcing standards and providing training, outreach, education, and assistance. OSHA achieves its mission by developing regulations that focus on occupational safety and health, conducting inspections of workplaces to ensure compliance, and providing resources for education on best practices in safety. This emphasis on workplace safety and injury prevention is central to OSHA's role and distinguishes it from other organizations that focus on different areas of health and research.

In contrast, other organizations mentioned in the options have different focuses: the National Institutes of Health is primarily involved in biomedical and public health research; the Centers for Disease Control and Prevention is focused on disease prevention and health promotion at the community and population level; and the Food and Drug Administration oversees food safety, pharmaceuticals, and medical devices. Each of these organizations plays a significant role in public health, but none are specifically dedicated to workplace safety in the manner that OSHA is.
