History

Historical Context

The 1984 Bhopal leak by Union Carbide of about 32 tons of methyl isocyanate killed roughly 3,800 people and exposed half a million residents, prompting a $470 million settlement and tighter hazardous-material laws. Those regulations shaped California’s Toxic Substances Control Act enforcement, so when an inert plume forced a one-mile shelter-in-place advisory on South Cypress Street, authorities applied protocols born from Bhopal’s legacy.
