Museum collections are irreplaceable: Louvre's Mona Lisa, Topkapi diamond, Hittite tablets at Anatolian Civilizations. Fire destroys; water staining damages just as badly. NFPA 909 covers heritage-protection rules — pre-action sprinklers and aspirating smoke detection are the backbone.
Museum Risk Profile
- Fire: Wood, canvas, textile
- Water: Paper, parchment, miniature
- Smoke: Condensation on bronze
- Temperature: 50 C+ cracks varnish
- Humidity: RH 45-55 percent fixed
Pre-Action Sprinkler
- Double interlock: Detection + sprinkler opening
- Dry pipe: No water normally
- N2 supervision: 40 kPa pressure
- K-factor: K=80 quick-response
- Density: 4.1 L/min/m2 light hazard
Aspirating Smoke Detection
- VESDA: Very Early Smoke Detection
- Sensitivity: 0.005 percent obscuration/m
- Pipe: 50 m max per sampling
- Alarm levels: Alert/Action/Fire 3-stage
- Ceiling: Ideal for high-ceiling galleries
Water Mist and Gas
- Water mist: 50 micron, 0.1 percent water damage
- Inergen: Preferred for rare-book rooms
- FM-200: Electronics cabinet
- Clean agent: No post-fire residue
- Hybrid: Mist + sprinkler
World and Turkish Examples
- Notre-Dame 2019: Roof fire, masonry saved
- Rio Museum 2018: 20 M objects lost
- Topkapi: VESDA + pre-action
- Anatolian Civilizations: Ankara - NFPA 909
- Hagia Sophia: 1500-year mosaics
