1.4.2 Air well
E
Explanations & Illustrations
Clause 1.4.2 : Air well
( No illustration )
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.
“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 |
R
Rationale - Clause table 1.4.2
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.

a. Renal dialysis day centres;
b. Aesthetic clinics;
c. Non-mental rehabilitation day centres; and
d. Endoscopy clinics.
“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.

1.4.9 Area of refuge

Explanations & Illustrations
Clause 1.4.9 : Area of refuge
Section a - a
Figure 1.4.9 - 1
For building A to qualify for reduction in the provision of exits, adjoining building B must act as an area of refuge.
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.
Figure 1.4.9 - 2
An area in an adjoining part of the same building may act as an area of refuge.
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
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.
“Area of refuge” refers to an area within a building, or in an adjoining building, where evacuees can temporarily take refuge, in lieu of the requirement for adequate exit staircase provision. It shall be adequately separated from the rest of the building or adjoining building by fire-resisting construction, and connected via an external corridor or open-sided linkway. The area of refuge shall be always accessible.

Section
Figure 1.4.73 - 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 C 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.
“Notional boundary” refers to an imaginary boundary which exists at equal distance between buildings on the same site, or the centre of the width of a public road/ drain/ sewer reserve, provided that the boundary is fronting the respective reserves.

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.
(c) 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.
(d) 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.
“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.
