Business in bhopal introduction

Business in BhopalIntroduction

Time: Deep night in December 2, 1984

Place: Bhopal, India

Result:

  • More than 2,500 residents died

  • Tens of thousands more suffered irreparable respiratory and neurological damage

    Direct Reason: Maintenance crew flushed the lines of the MIC unit with water inducing volatile chemical reaction.


Business in bhopal questions

Business in BhopalQuestions

Questions:

1- Why did this incident happen?

2- What efforts were made to control the situation?

3- Analyse this case using the Fault Tree analysis. Note: see the FAQ on your course website regarding some useful hints for FTA.


Business in bhopal why

Business in Bhopal:Why?

  • Long boring shifts of monitoring

  • No training in emergency procedures

  • Aging and deteriorating plant not being fixed

  • Unrepaired instruments and broken equipment

  • Staff layoffs of maintenance people, new and inexperienced staff


Business in bhopal why1

Business in Bhopal:Why?

  • Humans as living sensors for leak detection

  • Cultural issues: demanding English of employees

  • Temperature in tank missing or inaccessible (no history)

  • Operators had to enter a physiologically dangerous environment to turn valves off

  • Inadequate safety systems, soda scrubber, dismantled flame tower, shower curtain


Business in bhopal efforts made

Business in Bhopal:Efforts Made

  • Isolate the leak by closing various valves in the network of pipes – pressure was far too high

  • Reduce the temperature – no refrigeration coolant

  • Empty the tank 610 – no other free place available

  • Start up majors safety system – was not working

  • Divert the leaked plume to the flare tower – the connected pipe had been removed

  • Turn on the water curtain – water was not powerful enough to reach the plume

Note:

This is the correct tree, there should be no lines between the right hand branches and “AND” as the lower branches do not cause the higher branch’s failure, for example: the refrigeration unit not working do not cause the vent gas scrubber’s failure, these are both events occurring at different times and both causing the MIC spread over the village.
