Can anyone tell me the difference between the risk elimination and risk substitution..
For example: if we remove the source of risk introduce new thing which has less or no risk as previous then what would we say?is it elimination or is it substitution?
pls explain with practical examples
Thanks & Regards,
Annus

I suspect the answer to your question is often going to be "both".
Does that help? Do you have specific examples in mind?

Starting from my Economics 101 base that there is no free lunch, to my mind, elimination does not include introducing a new thing but would be the complete withdrawal from an activity. Even then, there is a risk to the portfolio due to unknown impact of withdrawal such as market reaction, portfolio rebalancing, complimentary products, etc. Introduction of of thing perceived to have less or no risk is substitution to my mind,

I'll offer a bit of an explanation. I'm sure others may disagree.
The concept of risk relates to the concept of vulnerability. If there is no vulnerability, the risk is non-existent. I'll talk in terms of vulnerability reduction and substitution because the definition of risk is anthromorphic
You can eliminate vulnerability by moving a facility or massively over designing the facility to withstand both external and internal vulnerabilities. Consider: Relocate the refinery inland to eliminate the risk from hurricane damage and the vulnerability from the same. But you may introduce a vulnerability to damage from earthquake or prairie fire or forest fire or airplane crash.
In that regard, there is no such thing as a facility with "no risk" or no vulnerability. When we attempt to make things foolproof, nature invents a better class of fool.
Vulnerability by substitution can occur through use of such things as intrinsic safe design or chemical substitution which eliminates certain classes of vulnerability from explosion or toxic formations because the chemistry is different. (Consider what might have happened at Bophal if Union Carbide had not been using MIC for the reactions.
So: To summarize: Vulnerability elimination occurs with specific actions and reduces certain types of vulnerabilities - through relocation or redesign. Vulnerability substitution occurs when one makes changes in the type of operation to change the basic process to eliminate one or more types of vulnerabilities from specifi sources while producing the same products.
Hope that helps.
Would like to hear your ideas/thoughts as well.
Thanks
