Fire Safety Sectional Committee, CED 36 FOREWORD This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Fire Safety Sectional Committee had been approved by the Civil Engineering Division Council. Temporary structures including large pandals normally erected at fairs, festivals and such other outdoor assembly have not, in general, been subjected to adequate regulations from fire safety point of view though in certain regions certain minimum fire precautionary measures in the construction of such structures are ensured before giving a licence or permission for the erection of such structures. Therefore, with a view to give necessary guidance with regard to fire protection measures to be adopted in the erection of such structures, it has been felt necessary to formulate this standard. This standard was first published in 1978, covering the safety aspects for temporary structures and pandals used by public excluding the temporary structures used for private functions. Since then the number of Indian Standards in regard to details of construction, fire safety and equipment have been formulated. The standard was revised in 1993 wherein having seen the more usage of temporary structures for private functions, the scope of this standard was enlarged to cover such type of structures also. This revision has been prepared so as to cover details of construction and use of fire fighting equipment according to the latest standards. Further the provisions have been aligned with National Building Code 2005. The composition of the Committee responsible for the formulation of this standard is given in Annex A.
