Study Notes
Fire Safety Objectives
- Fire safety objectives: aesthetics, functionality, technology and economy.
Design Considerations
- Designers must be conscious of fire safety objectives and tactics.
Fire Safety Tactics
- Five fire safety tactics include: prevention, communication, escape, containment and extinguishment.
Fire Safety Components
- Fire safety components include: the building, furniture, fittings, occupants and fire safety systems such as sprinklers.
Structure Fire Precautions
- For buildings without sprinklers, store rooms exceeding 10 square meters need to be individually compartmentalized with a fire resistance rating of at least one hour.
- Sprinklered buildings do not need compartmentation for store rooms.
Types of Travel Distances
- Chapters in the Fire Safety Management document cover details on travel distances and exit facilities.
Determination of Exit Requirements
- Exit requirements are influenced by factors such as occupancy type, area, occupant load per room or floor, exit capacity and travel distance to an exit.
Purpose Groups
- Different purpose groups exist with specific regulations related to fire safety, such as PG I (small residential), PG II (other residential), PG III (institution), PG IV (office) and others.
Occupant Load (OL) vs. Exit Capacity (EC)
- Occupant load: The number of persons that can occupy a building at any one time.
- Exit capacity: The maximum number of people allowed to use exit staircases or exit doors.
Occupant Load Calculation
- To calculate occupant load, the floor area available for occupation is multiplied by the appropriate areas per person from Table 1.4B in the Fire Code, unless prior approval is obtained from the Singapore Civil Defence Force (SCDF) for other occupancy load factors.
Smoke-Free Approach to Exit Staircase
- In basement occupancies, a smoke-free lobby must be provided for both a fire lift lobby and at least one exit staircase, and the smoke-free lobby must be mechanically ventilated.
- For buildings exceeding four storeys, omitting the smoke-free lobby leading to the exit staircase is allowed under certain conditions, including cross-ventilation, non-purpose group III and VII buildings, internal exit staircase with pressurization, and external exit staircase construction.
Person with Disabilities (PWD) Holding Areas
- PWD holding points should be provided on all storeys except for the first or grade level to enable PWDs to safely wait for assistance during evacuation.
- At least two designated PWD holding points must be positioned remotely on every storey, except for buildings with a single exit staircase.
- In a fire emergency, there should be a suitable means of communication between the PWD holding point and the Fire Control Centre (FCC) or a 24-hour manned station.
Exit Facilities
- Types of exit facilities include: internal exit passageway, external exit passageway, internal exit staircase and external exit staircase.
Internal Exit Passageway
- Internal exit passageways must be at least 1.5 meters wide, have fire doors, and a full height masonry wall separating them from exterior walls.
External Exit Corridor/Passageway
- External corridor/passageways must have a minimum fire resistance rating of one hour, be at least 1.1 meters above the corridor floor level, have a roof over the passageway and be a minimum of 1100mm wide for external corridors and 1800mm for external exit passageways.
- Parapet or balustrade must be at least 1 meter high.
Internal Staircase & Smoke-Free Lobby
- Industrial units must have smoke-free lobbies with a one-hour rated fire door, a fire lift lobby with a one-hour rated fire door and fire lift with a pressurization shaft.
External Staircase
- External staircases should be at least 3 metres away from industrial units and be separated by full height masonry walls.
Spiral Staircase
- Spiral staircases should have a maximum height of 10 metres with a tread depth of 190 mm, a headroom of at least 2.1 meters, and a maximum rise of 175mm.
