Which agency is responsible for defining safety regulations for the workplace?

The agency responsible for defining safety regulations for the workplace is OSHA, or the Occupational Safety and Health Administration. OSHA is part of the U.S. Department of Labor and was created to ensure safe and healthy working conditions for workers by setting and enforcing standards and by providing training, outreach, education, and assistance.

OSHA's significant role involves developing regulations that employers must follow to protect their employees from hazards such as exposure to harmful substances, extreme conditions, and various physical risks. By establishing these standards, OSHA aims to reduce workplace injuries, illnesses, and fatalities, making it a crucial authority in occupational health and safety.

In contrast, other agencies mentioned focus on different areas; GHS (Globally Harmonized System) is more concerned with chemical classification and labeling rather than workplace conditions, ADEQ (Arizona Department of Environmental Quality) deals with environmental issues, and EPA (Environmental Protection Agency) addresses broader environmental protection topics, including air and water quality. These distinctions clarify why OSHA is the correct agency for workplace safety regulations.
