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.
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.
