As per legislations, generally, fire no objection certificate (NOC) is issued by concerned fire service department, if the height of the building is above 15 m.
However, this requirement needs to be changed to all buildings, irrespective of height and use.
Many fire incidents are attributed to short circuits, as we read from news papers.
Some incidents are due to materials handled in the buildings, and these buildings / dwellings are not necessarily above 15 m height.
Many use part of the house/commercial complex as storage of substances, solvents, fire crackers, etc legally / illegally.
Some may not intend to use the building initially for dangerous substances, but later on, may use for the same. The initial conditions are not valid, later.
All the above, make one to feel it necessary for legislations that require fire NOC, apart from other requirements, mandatory.
