Hii Thaanx for the valuable response. As most of you people said,Its the authorities demand and we have to do it accordingly.Also I suppose its a case where we are providing better protection rather than confining to the minimum reqd. I have redesigned the system for Ordinary Hazard group 2 and got the approval. :) anyway it was really helpful to have your views.
For Mr andrew- It is under civil defence JAFZA.and its wasnt a fire hazard report. Thaanxx again...
