Reasons what led to the Bhopal Gas Disaster
The 1985 reports give a picture of what led to the disaster …show more content…
3. There was only one manual back-up system, compared to a four-stage system used in the US.
4. The flare tower and the vent gas scrubber had been out of service for five months before the disaster. The gas scrubber therefore did not treat escaping gases with sodium hydroxide (caustic soda), which might have brought the concentration down to a safe level. Even if the scrubber had been working, according to Weir, investigations in the aftermath of the disaster discovered that the maximum pressure it could handle was only one-quarter of that which was present in the accident. Furthermore, the flare tower itself was improperly designed and could only hold one-quarter of the volume of gas that was leaked in 1984.
5. To reduce energy costs, the refrigeration system, designed to inhibit the volatilization of MIC, had been left idle—the MIC was kept at 20 degrees Celsius (room temperature), not the 4.5 degrees advised by the manual, and some of the coolant was being used elsewhere.
6. The steam boiler, intended to clean the pipes, was out of action for unknown reasons.
7. Slip-blind plates that would have prevented water from pipes being cleaned from leaking into the MIC tanks through faulty valves were not installed. Their installation had been omitted from the cleaning checklist.
8. Water sprays designed to "knock down" gas leaks were poorly designed—set
