Which regulatory body sets safety standards for agricultural equipment?

The correct choice is OSHA, which stands for the Occupational Safety and Health Administration. This agency is responsible for ensuring safe and healthy working conditions for employees across various industries, including agriculture. OSHA establishes and enforces standards that aim to reduce workplace hazards and protect workers' safety, particularly in environments where agricultural equipment is used.

In the context of agricultural equipment, OSHA’s guidelines help mitigate risks associated with machinery, electrical hazards, hazardous materials, and ergonomic impacts on workers. By creating standards that agricultural operations must adhere to, OSHA plays a critical role in promoting safety on farms and ensuring that equipment is used in a manner that minimizes accidents and injuries.

The other regulatory bodies mentioned, such as the FDA (Food and Drug Administration), primarily focus on food safety and pharmaceutical regulation. The EPA (Environmental Protection Agency) is concerned with environmental protection and regulations related to pesticides and pollutants, and the USDA (United States Department of Agriculture) deals with agricultural policies, food production, and related issues but does not specifically set safety standards for equipment. Therefore, OSHA is the appropriate choice when discussing safety standards in agricultural equipment.
