Which agency oversees safety in nanotechnology?

The agency responsible for overseeing safety in nanotechnology is the Occupational Safety and Health Administration (OSHA). OSHA focuses on ensuring workplace safety and health regulations across various industries, including those that may work with nanomaterials. Since nanotechnology can introduce new risks due to the unique properties of nanoscale materials, OSHA is concerned with how these materials might affect worker health and safety. They provide guidelines and standards for safe handling and exposure limits for workers involved in nanotechnology processes. This oversight is critical, as the implications of nanotechnology on human health and the environment are still being researched, making safety regulations essential for those working in this field.

While other agencies like the FDA (Food and Drug Administration) and EPA (Environmental Protection Agency) also have roles concerning nanotechnology—primarily focusing on products and environmental safety, respectively—OSHA's mandate is specifically tailored to occupational safety, thus making it the correct choice in this context.
