11. Means Of Evacuation The term ‘High Rise Building’ means…
Moving up and moving down is a major challenge.
Are we right in advising
“In case of fire, do not use lift ; use the stairs”? .

12. Vertical Transportation
The need for fully protected fire lift
Lift (Elevator) : Escalator
Passenger lift : Freight lift : Fire lift

13. FIRE LIFTS Requirements as per NBC
Part 4-Section 4
Annexure C- C.1.5
Part 8 Section 5
6.7 Fire Protection
6.8 Requirements for
fireman’s lift

14. FIRE LIFT-DESIGN REQIUREMENTS
Structural
Electrical
Functional

15. FIRE LIFT –STRUCTURAL REQUIREMENTS
FIRE RESISTANCE (AS PER NBC)
Walls of lift : 2hr
Landing doors of lift enclosure :1hr
Lift separator wall : 2hr
Lift car door : ½ hr
Solid doors :1 hr
Lobby : ½ hr

16. FIRE LIFT –STRUCTURAL REQUIREMENTS – Cont.
Measures to minimize spread of fire from machine room:

17. FIRE LIFT –STRUCTURAL REQUIREMENTS – Cont.
Slope to prevent water
Machine room at the top separated by floor
Vent at the top of the shaft

20. FUNCTIONAL REQIUREMENTS
Minimum capacity 8 persons (544kg)
During fire, only fire man can use

25. Can Fire Fighters use Elevators during Fire?
Improve Reliability by
Improving Design
Ensuring Independent / Alternate Power
Enhanced Inspections / Maintenance
Improved Communication & Information
Implement Necessary Training Programs
Adopt & Improve SOP

26. ANY ?
PLEASE

27. Thank you
