Regulation on the Fire Protection of Buildings (Binaların Yangından Korunması Hakkında Yönetmelik)

Overview

The Regulation on the Fire Protection of Buildings (Decision 2007/12937, Official Gazette 26735, 19.12.2007) is Turkey's main fire legislation and applies to the design, construction, operation and maintenance of all buildings. Data centre projects are directly subject to it.

On the electrical side, the regulation requires main electrical distribution rooms, in-building transformer and medium-voltage centres and generator rooms to have fire compartment walls and floors (Article 24(2)). Transformer room walls, floor and ceiling must have at least 120 minutes of fire resistance, and oil-filled transformers need an oil collection pit (Article 65). For generator rooms the walls, floor and ceiling must also have at least 120 minutes of resistance, with no water, waste, flammable liquid or gas piping passing through and no wet rooms above (Article 66).

Cable penetrations between fire compartments must be sealed with fire-stopping mortar, pillows, panels or similar elements (Article 69(1)). Gaseous suppression design is based on TS ISO 14520, with audible and visual pre-discharge warnings and automatic closing of vents and dampers on detection and discharge (Article 98(3)-(4)). Accredited oxygen-reduction systems may be used in normally unoccupied enclosed spaces such as IT system rooms (Article 98(6), added in 2015). Alarm and fault outputs of the gaseous suppression system must be connected to the fire alarm system with separate zone indication (Article 79(1)). Because the regulation addresses buildings in general, data-centre-specific detail should be read together with relevant standards and the fire authority's view.

Key points

1. Main electrical distribution rooms, in-building transformer and MV centres and generator rooms must have fire compartment walls and floors (Article 24(2)).
2. Transformer room walls, floor and ceiling need at least 120 minutes of fire resistance; oil-filled transformers need an oil collection pit (Article 65).
3. Generator room walls, floor and ceiling need at least 120 minutes; no water, waste, flammable liquid or gas piping through it and no wet rooms above (Article 66).
4. Cable penetrations between fire compartments must be sealed with fire-stopping mortar, pillows, panels or similar (Article 69(1)).
5. Gaseous suppression design is based on TS ISO 14520, with audible and visual pre-discharge warnings and automatic closing of vents and dampers (Article 98(3)-(4)).
6. Accredited oxygen-reduction systems may be used in normally unoccupied enclosed spaces such as IT system rooms (Article 98(6)).
7. Gaseous suppression alarm and fault outputs must connect to the fire alarm system with separate zone indication (Article 79(1)).

Using it in design

• In the TR profile, default IT-room suppression to a TS ISO 14520 clean-agent design with damper-close interlocks.
• Offer oxygen-reduction (hypoxic) systems as an option for unoccupied rooms.
• Enforce 120-minute construction around transformer and generator rooms, with oil pits for oil-filled units.
• Flag any cable tray crossing a compartment line without a fire-stop element.
• Add connection of suppression alarm and fault outputs to the fire alarm system to the checklist.

Who should read it

Engineers designing data centre fire safety, electrical and generator rooms in Turkey, and project managers handling permits.
