1.3

Abbreviations

The abbreviations used in this Code are listed in Table 1.3A.

1.4

Definitions

In this Code, unless the context otherwise requires, the following definitions will apply.

1.4.1

Accessible Floor Area (AFA)

“Accessible floor area” refers to the total floor area of all covered spaces within a building, including service ducts, lift shafts, toilets, staircases, areas occupied by fixed/ moveable furniture/ equipment/ facilities, and any open-to-sky habitable areas above or below the first storey of the building.

1.4.2

Air well

“Air well” refers to a space(s) enclosed substantially by building(s) and directly open to the sky. An air well can be considered as an external space if it meets the minimum clear width and length below:

TABLE 1.4.2 - AIR WELL SIZE

Max. Habitable Height of Building

Min. Clear Width and Length of Air Well

18m

10m

24m

11m

36m

12m

48m

13m

60m and above

14m

Explanations & Illustrations

The minimum air well size specification in Table 1.4.2 is intended for exit staircase ventilation via an external space that is within an air well situation. To qualify as external space, the air well size shall comply with Table 1.4.2 and air well shall be devoid of any overhead obstruction such as trellis over the air well as it may have an adverse effect on smoke ventilation.

Readers should not confuse the ventilation requirements for smoke-stop lobby with that for exit staircase where the air well size differs. To qualify as external space under Cl.2.2.13a.(3), the air well size shall have minimum width 6m and a superficial plan area of not less than 93m2. However, in the case of exit staircase ventilation via an air well, the minimum clear width of the air well is 10m.

Rationale

The table stipulates the minimum size of an air well for effective smoke ventilation equivalent to an external space. These dimensions have been validated through fire engineering study.

1.4.3

Ambulatory care facility

"Ambulatory care facility” is a building, or part thereof, used for providing services on an out-patient basis for treatment for patients which would render them incapable of taking action for self-preservation or safety under emergency conditions without assistance from others, such as haemodialysis units or surgical treatment requiring general anaesthesia. Such facilities shall include the followings:

  1. Renal dialysis day centres;

  2. Aesthetic clinics;

  3. Non-mental rehabilitation day centres; and

  4. Endoscopy clinics.

1.4.4

Ancillary office

“Ancillary office” refers to any office which supports the activities of a building within Purpose Groups III, V, VI, VII and VIII and which is located within the same building or compartment as the purpose group it serves.

For building A to qualify for reduction in the provision of exits, adjoining building B must act as an area of refuge.

Figure 1.4.9 - 2
Figure 1.4.9 - 2

Note : The area of refuge is a temporary holding area. Hence the staircases provided need not be designed to accommodate all the people that will occupy the area of refuge in case of emergency.

An area in an adjoining part of the same building may act as an area of refuge.

Figure 1.4.9 - 3 : Acceptable proposal
Figure 1.4.9 - 3 : Acceptable proposal

It is acceptable for compartment B to act as an area of refuge for compartment A or vice versa as the access is through an open sided corridor.

Figure 1.4.9 - 4 : Not acceptable proposal
Figure 1.4.9 - 4 : Not acceptable proposal

Compartment B is acting as an area of refuge to compartment A which is not meeting the intent of the Fire Code, hence not acceptable.

Note : It is critical that the area of refuge shall be accessible to evacuees in times of emergency. Where there is doubt that evacuees would not be able to gain access to the area of refuge owing to locking of doors and different tenancies, the concept of area of refuge would not work.

1.4.10

Section
Figure 1.4.37

For building A the pitched roof is not considered as part of the structural frame of the building. However, the RC slab and beam supporting the pitched roof are considered elements of structures as they help to carry the dead load imposed by the pitched roof. For building B the RC roof is not considered as an element of structure. However, the beams supporting the RC roof are considered to be elements of structure of the building.

The columns supporting the pitch roofs are not element of structure as they are not part of the column supporting the whole building. Hence the columns only need to be constructed of non-combustible material.

Section
Figure 1.4.75 - 2 : Notional boundary between a warehouse and factory sited within a development plot of land bounded by common boundaries

The extent of unprotected openings e.g. windows in the external wall of a building is controlled by the space separation between the building and the boundary. The greater the building setback, the higher the extent of unprotected openings that would be allowed in the external wall. This is to address the concern of spread of fire from one building to another. The use of the boundary instead of another building makes it possible to work out the extent of unprotected openings even where another building does not exist.

In some situations, the distance to other building on the same site needs to be considered to prevent spread of fire. This is done by assuming a boundary called notional boundary. A notional boundary should be so situated that all buildings comply with the safe distance requirements as annotated in X and Y in the above diagrams. The boundary, which a wall faces (at an angle of 80º or less) whether it is the boundary of the site or a notional boundary is called the relevant boundary.

In the diagram, if the total setback distance for warehouse and factory is more than or equal to X + Y, then the setback distance is considered complied with provided that both buildings are within the same lot.

  1. Nursing homes;

  2. Convalescent homes; and

  3. Hospice.

1.4.77

Occupant load

“Occupant load” of a building, or part thereof, refers to the total number of persons that can occupy such a building, or part thereof, at any one time. The “occupant load” shall be determined by:

  1. multiplying the floor area(s) available for occupation with the appropriate areas per person as stated in Table 1.4B, unless prior approval is obtained from SCDF for any other occupancy load factors not stated in this table, or 

  2. the number of fixed seating, if applicable, for assembly occupancies.

Explanations & Illustrations

  1.  Table 1.4B gives a range of occupant load factors. To calculate the occupant load of a floor space for example an office, apply the formula:

Occupant load
= Floor area office (1000m2) / Occupant load factor for office (10m2)
= 1000m2 / 10m2/person
= 100 persons

    1. The occupant load for theatre or cinema where there is fixed seating, the posted occupant load based on number of seats can be taken.

    2. The back stage areas shall be separately calculated based on floor area.

    3. Where there are spaces provided for flexible seating, the occupant load for these spaces shall be separately calculated based on floor area.

Explanations & Illustrations

Section Figure 1.4.81 : Permitted limit of unprotected area
Section
Figure 1.4.81 : Permitted limit of unprotected area

The main concern of unprotected openings in external walls is to ensure that spread of fire through heat radiation from one building to another would be minimised. However, Cl.3.5.3 does permit relaxation for buildings, which are sprinkler-protected or solely used as car parks.

1.4.82

Plastic

  3. a roof.

Explanations & Illustrations

Section Figure 1.4.86 : Protecting structure
Section
Figure 1.4.86 : Protecting structure

There is a need to differentiate protecting structure to shaft from other elements of structures such as compartment walls, separating walls and external walls. This is for the purpose of working out differently the necessary period of fire resistance rating to the protecting structures. For example, Cl.3.8.6 permits door to protected shaft to have ½ the period of fire resistance rating of the enclosing protecting structures to an exit staircase.

1.4.87

Purpose Group (PG)

“Purpose Group” refers to the categorisation of buildings in this Code, with the aim of specifying relevant fire safety criteria for that building type. Where a building is divided into compartments used for different purposes, the purpose group of each compartment shall be determined individually, provided that where the whole or part of a building or compartment is used for more than one purpose, only the main purpose of that building or compartment shall be taken into account in determining into which purpose group it falls. See Table 1.4A.

Explanations & Illustrations

  1. For the purpose of complying with fire safety requirements under this Code, every building or compartment shall be treated according to its use or intended use as prescribed under Table 1.4A.

  2. Flatted factory building

    Section Figure 1.4.85
    Section
    Figure 1.4.85

Each floor is a compartment with 6th storey being further divided into 2 compartments, having 40% office and 60% factory use. The main purpose of use of 6th storey is factory, thus 6th storey is to be treated as factory use. Similarly, a building may have shops, offices and restaurants, but it is classified as shopping centre as the main purpose of use of the building is shopping.

  1. Townhouses

Under the Fire Safety (Exemption) order, proposal for detached, semi- detached, terraced and linked houses which do not exceed 3 storeys or levels, including basement or attic are not required to be submitted to the SCDF for approval. The Qualified Person in charge of the project shall self-regulate to ensure that all relevant fire safety requirements are complied with on site. However, townhouses, which are treated as under PG I for the purpose of complying with fire safety requirements that are applicable to detached, semi-detached terraced and linked houses, are not covered by the Fire Safety (Exemption) Order, hence, submission of plans to the SCDF is required.

  1. Serviced apartments/maisonettes

Serviced apartments/maisonettes would be treated as hotels or boarding houses under PG VII at the outset. However, the SCDF may consider to reclassify it under PG II if the floor layout of the units and escape corridors is similar to that of a typical apartments/maisonettes building.

1.4.88

Refuge floor

“Refuge floor” refers to a floor adequately separated from the rest of the building by fire-resisting construction. It serves as an area where evacuees can temporarily take refuge for buildings with long vertical evacuation routes to the building’s external space.
