I am not sure I understand your question. Information about all the topics you mention can be obtained from the U.S. Department of Labor. Their web site offers a wealth of information. Health and safely issues are covered by OSHA, a division of the U.S. DOL. Also check with your state department of labor to learn about state issues that may differ from federal ones. States sometimes have more stringent requirements than federal ones.
