(3) PG II buildings exceeding 10m habitable height
For a building under PG II that exceeds the habitable height of 10m, all of the following shall be complied with:
(a) A fire engine accessway/ fire engine access road shall be provided within a travel distance of 18m to the entrance of all exit staircases where the landing valves (dry or wet riser) are provided in accordance with Cl.6.2.2b..
Effective Date: 1 Sep 2024
R
Rationale - Clause 4.2.2a.(3)(a)
The reason for specifying fire engine accessways/access roads to be located within 18m of all exit staircases installed with dry riser is to reduce the distance that firefighters needs to travel to get to the landing valve. This will effectively reduce the time taken by the firefighters to tackle the fire and conduct rescue operation.

a. The fire loads in industrial premises are much higher and fires could be more complex in nature, scale and magnitude compared to commercial buildings. Larger compartment sizes are common in such buildings especially in process and storage areas. The high rack storage of materials creates a large volume of combustibles.
b. It is important to note that for industrial buildings, the gross cubical extent is used for the calculation of the extent of fire engine accessway required.
c. Sprinkler-protected buildings
For buildings protected by an automatic sprinkler system, the cubical extent of the buildings can be doubled.
For buildings under PG VI and VIII, a fire engine accessway shall be provided for firefighting appliances. The required length of the fire engine accessway shall be calculated based on the following gross cubical extent of the building (excluding basement) as follows:

The podium edge is obstructing the reach of the boom of firefighting appliance to 4th storey. Other obstructions could be roadside trees, entrance porch etc.. To allow full extension of aerial ladders at a safe climbing or elevation angle Ø of 60 to 80 degrees, sufficient space is needed to position the firefighting appliance.

Tower block is relocated nearer to the edge of the podium base to avoid obstruction to the boom of firefighting appliance.
The firefighting appliance shall be located at least 2m, but not more than 10m away from the external wall or façade (including any overhead obstruction) of the building. If the firefighting appliance is located within 2m from the building, the aerial ladder when set-up would fall outside the safe working limit i.e. the inclination of the ladder would be too steep.
If the firefighting appliance is located more than 10m from the building, the effective reach of the aerial ladder would be reduced.

4.2.3 Fire access opening to building for firefighting
a. Provision
Fire access openings shall be provided on the external wall for external firefighting and rescue operations. This can include unobstructed external wall openings, windows, balcony doors, glazed wall panels and access panels. There shall be a
minimum clearance area of 3.5m in width
and 2.5m in height around the fire access opening, and with minimum clearance
distance of 1.1m measured below the lower
edge of the fire access opening, and
400mm measured above the upper edge of
the fire access opening.
Windows, doors, wall panels or access panels shall be readily openable from the inside and outside. The inside and outside of fire access openings shall be unobstructed at all times during the occupancy of the building. There shall be no furniture or any other obstruction within 1m from the fire access openings at the landing inside the building.
Effective Date: 1 Sep 2023
R
Rationale - Clause 4.2.3a.
The purpose of providing fire access openings is to enable firefighters to gain access into the building from the exterior to rescue any trapped occupants and to facilitate external firefighting. Fire access openings shall not be located at exit staircases or smoke-stop/fire lift lobbies as these areas can be accessed through more conventional means.

Figure 4.2.3a. - 2
The purpose of the access opening is to enable firefighters to gain access from external to rescue any occupant who is trapped in the building and to allow firefighting from the outside of building. Access panels shall be placed at habitable spaces. In situation where the upper storey of a building is windowless, the FAPs could also be used for smoke and heat venting.
Access opening shall not be located at protected staircases or lobbies. As these spaces are being protected, there is no need for firefighters to gain access into them from the outside.
Sun shading to window shall be designed to have openable section in front of the designated FAP. QP should consult the SCDF for FAPs that are obstructed by the sun shading and seek acceptance on the method of opening or removal of that section of sun shading in front of the FAP before building plan submission.

Rationale - Clause 4.2.3c
The red/orange triangular signage provided on the external side of the fire access panels helps firefighters on the ground to locate the designated fire access openings readily during an emergency.

Clause 4.2.3c. : Fire access opening to building for firefighting
Figure 4.2.3c. : Signage for fire access opening
The signage, either in red or orange triangle would help firefighters on the ground to locate the designated access openings. The triangle can be upright or inverted.
d. Size
Fire access openings shall be not less than 850mm wide by 1m high with sill height of not more than 1.1m, and head height not less than 1.8m above the inside finished floor level.
Exception:
(1) The sill height can be extended to at most 1.25m for those fire access openings that are located at roof garden/ terrace.
e. Number and position of fire access openings for buildings other than residential
(1) Number of fire access opening
For PG III to VIII, the number of fire access opening shall be based on the length of the fire engine accessway. Every 20m of fire engine accessway or part thereof shall be provided with an access panel.
R
Rationale - Clause 4.2.3d
The sill height of not more than 1.1m is to facilitate the free movement of firefighters into or out of the building. Higher sill heights may impede their access and increases their risk of falling.
E
Explanations & Illustrations
Clause 4.2.3d. : Fire access opening to building for firefighting
Figure 4.2.3d. - 1
In Fig. (iii), although the height of access opening complies with the Clause (1000mm), the head height is less than 1800mm.
Figure 4.2.3d. - 2
Signage shall be provided to indicate the access openings, both inside and outside habitable rooms to prevent any obstruction at all times. High level access openings are not acceptable as firefighters could incur physical injuries if they fall down from the opening when trying to gain access into the building. The sill height of not more than 1100mm is to facilitate the free movement in/out of the building. Higher sill height would pose problems as firefighter could incur a fall when entering the building and restrict movement.
The minimum width of 850mm shall not include a mullion usually found in casement windows. The provision of mullion would reduce the access opening. This would cause difficulties to firefighters when trying to get into or out of the building, carrying with them equipment or injured occupant.

(2) Position
Fire access openings shall be remote from each other and located along the side of the building. Such fire access openings shall be spaced at most 20m apart measured along the external wall from centre to centre of the fire access openings. The fire access opening shall be distributed such that there is at least one opening at every 20m of the fire engine accessway, except for parts of the non-PG VI or non-PG VIII building that are single-storey.

Figure 4.2.3e.(2) - 3
Location of access openings should not be rigidly governed by the 20m-apart rule, as access panels should open into “habitable space” Thus, providing access openings at a “dead space” or “store room” is not allowed. However, access openings at the following areas should be avoided:
a. Staircases
b. Smoke stop lobbies
The distance between access openings may vary as deemed fit. It is not necessary to be 20m all the time. In some circumstances, it may be less than 20m, depending on the shape of the building, the floor layout and the usage of the various rooms at which access panels are being provided.
Access openings are meant for conducting rescue operation and fighting fires from the outside, while the firefighter rides on an aerial ladder. Providing an access opening in the staircase will not serve much purpose. It is unlikely that the fire is in the staircase; and gaining access into the staircase directly should be possible without having to do it from the firefighting appliances.

In situation where void or atrium interferes with the siting of FAPs, for example, FAPs 3 and 4 as shown in the above figure, QPs should consult the SCDF to determine the alternative suitable location for the affected FAPs and the adequacy of the overall provision per storey of the building up to 90m habitable height.
FAP 3 and FAP 4 shall have direct access to the commercial floor.

In long narrow sites, the provision of fire engine accessway would affect the layout of the building. To compensate for the lack of fire engine accessway, it would be necessary to provide internal firefighting facilities such as sprinkler system, fire lift, wet or dry rising main. QPs shall obtain waiver approvals prior to making building plan submission.
(3) Fire access opening to compartment or spaces
(a) For buildings under PG III, IV, V and VII exceeding the habitable height of 10m, and up to 90m, fire access openings are required at every storey level, other than the 1st storey, and shall face the fire engine accessway directly.
(b) For building under PG VI and VIII, fire engine access openings located over a fire engine accessway shall be provided along the external walls, up to a habitable height of 90m.
