Specification 19 Fire control centresTo clarify that Specification 19 provides the construction and content details for fire control centres and rooms.
Fire control centres or rooms
Specification 19 sets out the construction and content details for fire control centres and rooms required by the BCA.
A fire control room is a fire control centre in a dedicated room with specific requirements. See S19C7 which requires that where a fire control centre is in a building of more than 50 metres in effective height, the centre must be in a separate room.
S19C3 to S19C6 set out the requirements for fire control centres (including fire control rooms) while S19C7 to S19C13 set out additional requirements for fire control centres which are required to be located in a dedicated room, which is commonly referred to as a fire control room.
Note: this commentary also applies to S19C2.

Fire control centre required by E1D15
E1D15 sets out when a fire control centre is required in a building.
Exclusive purpose of centre
S19C3 sets out that a fire control centre must be for the exclusive purpose of:
In this context, the centre or room cannot be used for any other purpose.
To require that a fire control centre be conveniently placed to allow egress.
Egress
Egress from the fire control centre must not involve a change in level exceeding 300 mm. This is to help fire brigade officers carrying their equipment and make entry easy.
To limit the type of equipment allowed in a fire control centre.
Extraneous equipment not allowed
Since the fire control centre will be occupied by fire brigade personnel during a fire, possibly for a period long after the other occupants have evacuated, it must be suitable for directing fire brigade operations. Equipment which does not assist in this function, or could endanger the fire brigade personnel, is not allowed in the centre.
To minimise the risk of the sound levels in a fire control centre interfering with the room’s function.
Noise must not interfere with communications
The fire control centre is used to direct fire brigade operations during a fire in the building, possibly for a period long after the other occupants have evacuated. This involves communication with other fire brigade officers outside the centre. It is therefore important that ambient sound levels do not interfere with that communication.
To set out the construction details of fire control rooms.
Buildings over 50 metres in effective height
E1D15 requires certain buildings to contain a fire control centre. S19C7 only applies to those buildings with an effective height greater than 50 metres. In these buildings, a fire control centre must be within a dedicated room known as a fire control room. Since the fire control room will be occupied by fire brigade personnel during a fire in the building, it must be fire separated from the remainder of the building.
To require adequate access to a fire control room.
Application
Refer to comment on S19C1.
Access
The main provisions deal with access to the fire control room. Since it will be necessary for the fire brigade to gain access to the fire control room while the building is being evacuated, access to it must not be obstructed by people evacuating.
Providing access by way of two paths of travel is to help fire brigade access. One of those paths must be from the front entrance of the building, and the other must be from a public place or a fire-isolated passage which leads from a public place.
To set out the contents required in a fire control room.
Application
Refer to comment on S19C1.
S19C10(1) sets out the minimum size and contents required in a fire control room.
S19C10(2) lists additional items which may be contained in a fire control room. This list is not exhaustive, other items may be added provided the floor area of the room is increased, as required by S19C10(3).
S19C10(3) sets out the area requirements for fire control rooms.
To reduce the likelihood of smoke accumulating in a fire control room.
Application
Refer to comment on S19C1.
Since the fire control room will be occupied by fire brigade personnel, possibly for a period long after the other occupants have evacuated, it must have adequate means of preventing the accumulation of smoke. The room can have either natural ventilation complying with S19C11(1)(a) or a pressurisation system complying with S19C11(1)(b).
If natural ventilation is used, then the window or door must not open to another part of the building.
If a pressurisation system is used, it must comply with AS 1668.1 and the other provisions of S19C11(1)(b). This is achieved by treating the room similarly to a fire-isolated stairway, which includes:
To provide sufficient illumination to the fire control room during an emergency.
Application
Refer to comment on S19C1.
Since the fire control room will be occupied by fire brigade personnel during a fire in the building, possibly for a period long after the other occupants have evacuated, it must have appropriate levels of lighting. As the lighting must be maintained while the room is in use, it must be emergency lighting in case of failure of the building’s normal lighting system.
Normally, emergency lighting is only used for evacuation purposes. A fire control room is used to direct fire brigade operations, which will include such actions as reference to building plans, and the reading of other information. The amount of emergency lighting in the room must therefore be increased to 400 lux.
