Title 29 › Chapter 15— OCCUPATIONAL SAFETY AND HEALTH › § 669
The Secretary of Health and Human Services must run or pay for research, tests, and demonstrations about workplace safety and health. That includes mental and behavior studies, new tools and methods, and problems from new technology. The Secretary must work with the Secretary of Labor and other federal agencies to make specific research plans. Using that work and other information, the Secretary must write and publish safety criteria at least once a year. These criteria must include safe exposure levels for toxic materials and harmful physical agents for different lengths of work. The Secretary must also study long-term, low-level exposures and their effects on aging adults. The Secretary of Health and Human Services may require employers to measure, record, and report worker exposures and may set up medical exams and tests to track occupational illnesses. People can refuse medical exams for religious reasons unless the exam is needed to protect others. If an employer asks for help paying to measure exposures, the Secretary must help pay. Within six months of December 29, 1970, and at least once a year after that, the Secretary must publish a list of known toxic substances and the concentrations that cause harm. On written request, the Secretary must tell employers and workers whether a workplace substance may be toxic. If a substance is found toxic and no safety rule covers it, the Secretary must tell the Secretary of Labor right away with the supporting criteria. The Secretary may inspect workplaces, share information with employers and workers, make contracts for studies, and may delegate these duties to the Director of the National Institute for Occupational Safety and Health.
