50 Years of Workplace Safety and Health
President Nixon signs the Occupational Safety and Health Act on December 29, 1970.

Established by the Occupational Safety and Health Act of 1970, OSHA opens its doors on April 28, 1971. During its initial decade, OSHA issued the first standards for asbestos, lead, carcinogens, and cotton dust.
