Which entity puts out safety standards for all businesses in the United States?

The correct choice is indeed OSHA, which stands for the Occupational Safety and Health Administration. OSHA is a federal agency of the United States Department of Labor and is responsible for ensuring workplace health and safety. Established in 1970, OSHA sets and enforces standards to safeguard workers against various hazards in the workplace, thereby promoting safe and healthy working conditions.

OSHA's regulations cover a wide range of industries, including healthcare, manufacturing, construction, and many others, making it a critical resource for businesses aiming to comply with safety standards. The agency also provides training, outreach, education, and assistance to help businesses adhere to safety protocols and reduce workplace injuries and illnesses.

The other entities listed, while relevant in specific contexts, do not hold the same overarching authority when it comes to safety standards for all businesses across the United States. For instance, AAMA typically relates to the American Association of Medical Assistants, which focuses on the medical assisting profession, rather than broad safety regulations. RACE could refer to different organizations depending on the context, and RMA typically pertains to the Risk Management Association, which focuses more on risk management in financial contexts rather than safety standards for all businesses.
