Bhopal disaster and the push to create the CSB (1984–1998)
The 1984 Bhopal gas leak in India killed thousands and exposed how little was known about preventing chemical releases. In the U.S., the 1989 Phillips 66 Houston refinery explosion killed 23 workers. Congress added the CSB to the 1990 Clean Air Act, and the board began operating in 1998.
A new independent agency was created to investigate chemical accidents.
CSB investigations produced safety recommendations used by plants, regulators and unions across the petrochemical industry.
The agency was created precisely because no federal body investigated industrial chemical accidents. Eliminating it recreates that gap.
