The Occupational Safety and Health Act of 1970 (OSHA) was passed in order to insure as much as possible safe and healthy working conditions for employees. OSHA provides for establishing safety and health standards and for enforcement of these standards. The Secretary of Labor has been granted broad authority under OSHA to write occupational safety and health standards. Any person adversely affected by these regulations of the Secretary of Labor can challenge their validity in a U.S. Court of Appeals. The Secretary’s standards will be upheld if they are reasonable and supported by substantial evidence. The Secretary must show a need for a new standard by showing that it is reasonably necessary to protect employees against a significant risk of material health impairment. The Secretary also must show that the standard is economically feasible.
