The Parque Central was a 56 storey government office building in Caracas , Venezuela. The fire started on the 34th floor and climbed to the 47th floor
Overview of Fire Safety Requirements for Super High-rise Buildings
• Definition:
-Super high-rise buildings refer to buildings having more than 40 storeys/levels
-High-rise buildings refer to buildings having habitable height more than 24 metres
Commercial Industrial Residential
Means of Escape (Table 2.2A)
Means of Escape (Clause 2.4.6)
Exit staircases – 2 nos. Exit staircases (Clause 2.4.5)

Overview of Fire Safety Requirements for Super High-rise Buildings
• Beef up fire safety knowledge of security guards
• Correct operations of fire lifts
• Better manage common areas especially during
renovations
Arising from a tragic fire at Marina Bay Suites on 13 Jan 14,
Competent Persons (CPs) for such premises were appointed
to address gaps:
Update on Fire Safety Requirements for Super High-rise Private Residential Buildings
Update on Fire Safety Requirements for Super High-rise Private Residential Buildings
• On 26 Mar 2015, the requirement to appoint CP was
incorporated in the current Fire Code 2013
• The Competent Person such as managing agent’s
supervisor will undertake certain fire-safety related
duties
• Establish evacuation procedures, display and use of
refuge area, daily checks of common areas, briefing and
training of security guards etc.
Fire Evacuation Guidelines
Area of Refuge Concept
• Vertical fatigue>20 storeys
• Overcrowding in stairs for tall building especially high occupancy load
• Shorter distance to safety
• Shorter time to evacuate the occupants
• Prevent injury
• Study showing tendency of heat and smoke spreading upward
Fire Evacuation Guidelines
Fire Simulation Slides on High-rise Premises
Fire Evacuation Guidelines
1a) facilitate evacuation of occupants on the fire floor follow by 2 floors above the fire floor with immediate danger towards nearest staircase to ground level
Fire Simulations Conducted Showed The Need to Evacuate Upper Floors
Fire Evacuation Guidelines 1 b. facilitate evacuation of occupants on the fire floor follow by 2 floors above the fire floor with immediate danger towards nearest staircases to area of refuge at lower floor

Fire Evacuation Guidelines
2) facilitate evacuation of PWD from holding areas to safety (not applicable to residential) 3) facilitate evacuation of any other floors if the fire spreads beyond 2 floors above the fire floor and any floor below the fire
Fire Evacuation Guidelines
4) facilitate evacuation of occupants from refuge to Assembly Area (AA) (if necessary) 5) if total evacuation is needed, to commence full evacuation of occupants
Assembly Area (AA)
• Size sufficient to accommodate occupants from the buildings
• Safe distance from risks such as falling debris and spread of the fire
• AA shall not interfere with the fire fighting operations
Fire Evacuation Guidelines
Evacuation Strategy for Super High-rise Building
Total Evacuation
• Evacuation of all building occupants at once from a building to an outside area of safety
• The large number of people, limited accommodation of stairwells, longer lead time before discharging from staircases
• Other considerations include slowing down the fire-fighting access to the fire floor via staircases when evacuation is on, fatigue of evacuees, dizzy, slipping on surfaces etc
Phased or Zoned Evacuation
• This strategy provides for immediate, general evacuation of the areas of the building nearest the fire incident
• May be appropriate when the building’s fire protection features assure that occupants away from the evacuation zone will be protected from the effects of the fire for a reasonable time
• Evacuation of additional zones may be necessary once the occupants of the involved floors have been relocated
• The decision whether to evacuate them further depends on the fire situation
Evacuation Strategy for Super High-rise Building
Delayed Evacuation/Area of Refuge • This strategy takes advantage of temporary holding
places like at an area of refuge, where occupants can remain in relative safety for a period of time
• Evacuation can either by themselves, others or with assistance from emergency responders
• It can be used for occupants with disabilities who are waiting for assistance to help them evacuate

Determining Evacuation Strategy
• Depends on many factors like:
-fire protection systems
-size of building/usage
-height of building
-exit provisions
-management team
-maintenance of facilities, housekeeping etc.
