What do federal agencies establish concerning equipment and chemical ingredients?

Federal agencies, such as the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), play a crucial role in establishing guidelines for the manufacturing, sale, and use of equipment and chemical ingredients in various industries, including cosmetology. These guidelines ensure that products are safe for consumers and professionals, addressing aspects such as labeling, toxicology, and permissible levels of hazardous substances.

This framework is essential for protecting public health and safety, as it determines how products should be produced, what information must be provided to consumers and salon professionals, and how to handle them safely during use. Therefore, the correct choice reflects the agencies' responsibility to regulate and provide a consistent standard across the industry, ensuring that all parties are informed about the safety and efficacy of the chemicals and equipment involved in nail technology.
