Dear Abhay,

What is meant by maximum credible loss secnario study.

The studies are carried out by assessing the existing conditions of the workplace, process, operation, plant and equipment. On the basis of the observations made and results obtained, the industries are advised for minimizing or eliminating the hazards in the form of a study report. The total duration for carrying out the study and submission of the report depend upon the size of the plant, number of locations, number of samples collected, type of analytical method adopted, etc. As such, the study may be completed and report prepared within 4 months.

This includes determination of affected distance for the identified maximum credible loss scenarios using computer aided software. this distance wood indicate the radiation and over pressure level for flammable substances and vapor concentration for toxemic chemicals .By using this technique ,one can relocate the areas of the site which would be affected in the event of an emergency. Consequence analysis distance are in corporate in the on-site as well as off-site emergency management system

Dear all,

Wait for commands. . .

Thanks in advance

Dear Abhay,

Maximum credible (loss) accident analysis is one of the most widely used concepts in risk assessment of chemical process industries, which involves the following steps -

1. Development of credible accident scenarios. For the units of any industry being analysed, a set of scenarios are developed for accidents which are ‘credible’; the credibility being qualitatively understood as a combination of likelihood (of occurrence) and scale (of damage potential).

2. Delineation of maximum credible accident scenario. Based on the credibility of the accident scenarios they are ranked, and maximum credible accident scenarios are identified.

3. Damage calculations through mathematical modelling. The impact of these scenarios—for example explosion followed by a fire ball—is then studied using available models of explosion, boiling liquid expanding vapour cloud explosion (BLEVE), confined vapour cloud explosion (CVCE), vapour cloud explosion (VCE) and fire ball.

4. Risk estimation. Based on the damage potential estimated in the previous step and the probability of occurrence of these credible accident scenarios, risk factors are estimated.

Central to these steps is the aspect of ‘credibility’. A ‘credible’ accident is one which is within the region of possibility and which is also likely to be severe enough to cause significant damage.

Hope this answers you.

Once again, I'm late, due to tight schedule. Kindly regret, as it cannot be avoided in my current schedule.

But I'm happy to see many good questions arising from you. Keep on asking (with patience to get reply).

Dear Ragu,

Once again thank you for your valuable contribution. Keep on contributing. Even though I'm not answering all the posts, I'm having a look on the posts atleast during alternate days...

But due to current tight work schedule I'm unable to reply or take part immediately.

Dear KVS,
I wanted to thank you for your input that you have done specially on this thread(Mr.Abhay query). Again thank you very much sir. . . keep on touch. . .
Dear all/Seniors,
I hope your inputs/commands on this thread earliest. . .
Thanks in advance. . .
Dear Abhay,
Please let me know Mr.KVS answers full fill your query?

@ KVS Ji
Thanks for explanation . first three questions are mostly covered. kindly suggest that :

Here is a example of your MCLS for Toluene

Vinati Organics Limited <link updated to site home> ( Search On Cite | Search On Google )

<link outdated-removed>

toluene exposure <link updated to site home> ( Search On Cite | Search On Google )

Toluene

Is that kind of the material you want or just sops for dealing with storing toluene

Like

SOP 15 <link updated to site home>

None of the above is associated to fire plans or environmental issues it thats the case the sop and protection areas are listed in the emergency response guide for north ameria in the green pages

Emergency Response Guidebook 2008 - Transport Canada

Does any of these materials help
