Bhopal, The Inside Story: Carbide Workers Speak Out

4 ideas

1. The night Tank 610 released MIC

   On the night of December 2–3, 1984, water entered Tank 610 at Union Carbide's Bhopal pesticide plant. The tank held roughly 40 tons of methyl isocyanate, more than the recommended fill level, and the water triggered a runaway reaction that vented toxic gas over the sleeping city. At that moment the refrigeration unit had been shut down and drained of coolant, the vent gas scrubber was not operating, the flare tower was out of service, and the water spray could not reach the height of the escaping gas, so thousands died.

2. Safeguards that were weak or switched off

   At Bhopal the layered safety systems gave less protection than they appeared to. Chouhan argues that some, such as the vent gas scrubber and flare tower, were undersized for a major release even when working, and that others were switched off or left unrepaired for local reasons such as cost or maintenance. Redundancy that looked sound on paper was therefore partly inadequate by design and partly out of service.

3. Cost-cutting on a failing plant caused catastrophe

   The workers argue the disaster came from management decisions, not from a lone saboteur or operator error. Because the Bhopal plant was losing money, management cut staffing on the MIC unit, shortened training, removed maintenance positions and deferred repairs. When a site is being run down for divestment, safety spending is treated as discretionary, and the hazards stay just as lethal while the budget shrinks.

4. Frontline operators see the hazards first

   The workers who run the equipment know which gauges are unreliable, which systems are off and which near-misses have happened, including earlier leaks at the plant that injured and killed workers. Reading a disaster through their testimony exposes a gap between official safety claims and the plant's real condition. It also shows that warnings from below were available and went unheeded.
