3.0 Equivalencies

Equivalencies to any established prescriptive criteria of NFPA and its companion codes, standards and publications may be approved by the EHS-Fire Department / AHJ, if the alternative fire protection engineering design provides an equivalent level of fire protection and life safety. Written requests for approval shall include justification demonstrating equivalencies on the basis of pertinent data. Approved equivalencies and alternatives shall only apply to the specific building, facility or structure involved in extraordinary case where no technical alternatives exist; and shall not constitute blanket approval for similar cases.

NB (a) 1 to 3 as above (i) provide only an outline of the specific requirement(s) of EHS-Fire Department for the

guidance of qualified & approved consultants/users & (ii) serves as ready reckoner for maintaining consistency in approach. However, the consultants/users are cautioned and advised that they meet all requirements/recommendations as specified / cited in drawing review report(s) issued by EHS-Fire Department.

(b) Consultant shall submit design drawings meeting the above requirements and obtain approval of EHS Fire Department, before procurement of materials.

(c) Refer to Fire Department and relevant codes & standards for additional information/details.
