Risk Assessment is about identifying the potential hazards and risks associated with any substance, process or activity and determining ways to manage those hazards before the adverse effects become evident.
Risk Management takes a more multifaceted form if a system becomes more complex. This is what happened in Bhopal. It was in 2-3rd December, 1984; the World’s worst industrial disaster killed at least 20,000 people and left thousands maimed and helpless. The medical follow up done by Indian Council of Medical Research (ICMR), based on diverse multi-institutional projects over a 10 year period between January 1984 and May 1994, on the communities that were exposed to the leak provides a reasonably comprehensive viewpoint on both short and long-term health effects. Epidemiological studies formed the core of the study that included 25 research projects, including two multi-disciplinary ones on pathology and toxicology to determine the effects of inhaling noxious gases. The investigations also included clinical and toxicological studies. The entire work was coordinated by the Bhopal Gas Disaster Research Centre (BGDRC).
An International Journal stated earlier that the findings of the study were not made public till 2004. It was of belief that about 42 tones of Methyl Isocyanate (and other gaseous products of the runaway reaction) were leaked from the storage tank in 1984. Approximately about three-fourths of the storage tank population at that time was exposed to the leak. Large part of the populations were affected to different degrees and when experts debated on the ways to find solution, people died like flies. A total number of approximately 80,000 people were studied at severely, moderately and mildly exposed areas and compared with controls from unexposed areas. Later it was found – of the total population, 3.9 percent was affected severely, 8.6 percent moderately and 50.1 percent mildly, while 37.4 percent was not affected. Most people included in the study had no fixed occupation or fixed source of income. Nearly 70 percent of the people, lived in Kuccha houses, in the severely affected as well as control areas (areas where the gas had not spread), and prevalence of the smoking habit ranged from 0.2 to 14.3 per cent.
If one goes through the ICMR report then one could come to a conclusion that the three-fourth of the deaths occurred within the first 72 hours of the leak, which happened around mid night of December 2-3, 1984. It was the post-exposure phases that is now considered as depending on the varying clinical features, the different post-exposure phases have been classified in the study as acute (first month of exposure), sub-acute (one to three months) and chronic (more than three months). The ocular symptoms during the acute period were related to the effects of the gas(es) on the eyes and the respiratory tract. In the acute phase, in addition to respiratory complaints, including chest pain and breathlessness, there were complaints of muscle weakness, febrile illness and vomiting. After examination of blood, it was found that in this phase there were increased white blood cells and higher than normal hemoglobin levels. Situations of these types of can be termed as EXTREME EVENTS, which is beyond the natural capacity of the individuals to cope.
If we look through the doors of history then one can find that risk and crisis management is lettered with narratives about the ways in which the organizations failed to deal with the demands of ‘extreme events’. Extreme events by definition are a class of outcome that have very high consequences (often exceeding the perceived worst class scenario) but also a low probability of occurrence. These factors make them difficult areas for analysis and investigations. These may lead some individuals to come to a conclusion by dismissing their significance by stating that they are not representative of the ‘normal’ state of affairs within the ‘system’ under consideration. Extreme events call into question our understanding of the various classes of phenomenon in which they are found and the strategies that organizations have in place to deal with them.
Thus they confront the secretarial claims and their control systems and can often call into question many of the fundamental assumptions that are held about the nature of hazard. These types of extreme events are also found in Natural Disasters or catastrophes or go-physical phenomenon, extreme weather conditions and also for long term phenomenons like global warming.
For example, a region receives a clear warning about heavy downfall and the same place receives enough rainfall in a 24 hour period (which is equivalent to months of precipitation in the given region) then the scale of the event will definitely surprise many people and will cause situations which may be difficult for the local population to cope. Again, a clear look states that it is often the scale of the events that present challenges around prediction. These leads to elementary complexity in the provision of mitigating advice to those, who are exposed to these type of risks. However there are attempts to provide early warning systems to warn the people against the upcoming disasters.
‘Extreme Events’ are typified by being both high consequence and low probability events. They are events that have the potential to overpower our resistance and yet they occur so uncommonly that we are powerless to develop enough experience from them and expand effective management control strategies that are grounded in the normal trial and error learning process that characterize organizations.
Extreme eventsare however also characterized by the various attempts to ‘manage’ them so that one can prevent the process of its escalation that has the power to move a system within its boundaries of its normal perturbation towards an extreme position, where it can no longer be controlled and has the potential to cause considerable levels of damage. Here we need to understand the consequences of an extreme event rather than seeking to search for developed technologies of prognosticating their occurrence.
If we understand the possible harm that such ‘extreme events’ can cause, it would lead the outcome administrators to reflect on the process by which incidents can shoot up to generate considerable damage and how inadequate our understanding base is, which often depend around these processes.
Some organizations consider the nature of their past histories as evidence that they are ‘crisis prepared’ or ‘resilient’. The lack of sufficient information and evidence about the exact understanding of the possible harm of a particular catastrophic hazard is often seen as a ‘justification’ that the organization is prepared for such crisis. But what if these crisis takes the shape of an extreme event. The coping capacity of such organizations is largely a function of the assumptions that exist around controls, which work under a range of conditions and to an extent that they are able to cope with the task demands that they are generated by emergence.
If we look into the details then one arrives at a conclusion that there are few handful of managers who have an ‘Hand on’ experience of ‘crisis’ not necessarily an extreme event and that would allow them to manage these events with their own past histories he/she had undergone. Therefore the organizations need to engage in simulation exercises in order to ensure that managers have some experience of dealing with those processes around which the hazard might escalate. It would help if the mangers are also willing to consider the experience of other organizations, which are having similar experiences around such types of events. As crises are in essence, extreme events, our understanding of them will be a function of the observations that we can make ‘at a distance’ rather than by direct experimental learning.
However, what these extreme events do is to point to the manner in which managerial assumptions around control can generate the conditions in which catastrophic failures can occur. As such, they serve an important role in allowing us to develop strategies for coping with the consequences of extreme events or crisis by considering the range of impacts that such events can generate.
My assumption goes that these factors stated above may be lacking for what happened in Bhopal Gas Disaster in 1984. A deep look into these aspects and significant research with proper implementation of policies in these areas can help organizations, corporate and other agencies to tackle ‘extreme events’ more professionally and effectively.
