For its 40th anniversary, the Occupational Safety and Health Administration has compiled a timeline of key milestones during its history. The big picture is a positive one:

Although accurate statistics were not kept at the time, it is estimated that in 1970 around 14,000 workers were killed on the job. That number fell to approximately 4,340 in 2009. At the same time, U.S. employment has almost doubled and now includes over 130 million workers at more than 7.2 million worksites. Since the passage of the OSH Act, the rate of reported serious workplace injuries and illnesses has declined from 11 per 100 workers in 1972 to 3.6 per 100 workers in 2009. OSHA safety and health standards, including those for trenching, machine guarding, asbestos, benzene, lead, and bloodborne pathogens have prevented countless work-related injuries, illnesses and deaths. This timeline highlights key milestones in occupational safety and health history since the creation of OSHA.

The timeline includes OSHA standards, from the 1972 asbestos standard to the 2010 cranes and derricks standard. It also includes disasters that highlighted the need for OSHA action, like the 1984 release of methyl isocyanate (MIC) at Union Carbide’s plant in Bhopal, India, which killed at least 3,800 people immediately and continues to affect local residents’ health. The OSHA timeline explains that this disaster led to increased inspections of chemical plants, particularly those making or using MIC.
