Which organization is responsible for Occupational Safety and Health Administration?

The Occupational Safety and Health Administration, commonly known as OSHA, is the organization tasked with ensuring safe and healthy working conditions for employees in the United States. It accomplishes this by setting and enforcing standards, providing training, outreach, education, and assistance. OSHA was created in 1970 under the Occupational Safety and Health Act, which aims to reduce workplace hazards and implement safety standards that employers are obligated to follow to protect their workers.

Understanding this context highlights OSHA's critical role in promoting workplace safety and its authority to enforce regulations, conduct inspections, and impose penalties for non-compliance. This organizational focus on occupational safety is why OSHA is the correct answer to the question. Other organizations listed, such as the EPA (Environmental Protection Agency), ANSI (American National Standards Institute), and SDS (Safety Data Sheets), serve different functions within environmental protection, standardization, and chemical safety, respectively, but they do not oversee workplace safety regulations like OSHA does.
