• Detection: Fixed fire detection and alarm system in accommodation, corridors, stairways, escape routes
• Detection: Detectors and call points individually identifiable at fire alarm panel
• Detection: Cabin detectors trigger audible alarm within cabin
• Detection: Exemptions: private bathrooms, galleys, voids, public toilets, CO₂ rooms
• Detection: Balconies with non-restricted fire-risk furniture require detection
• Firefighting: Portable extinguishers in accommodation, service, control stations
• Firefighting: ≥5 portable extinguishers for ships ≥1,000 GT
• Firefighting: Water spraying/sprinkler system at 5 l/m²·min, connected to fire main
• Firefighting: Fire mains, pumps, hydrants, hoses, nozzles, international shore connections
• Preventing spread: A/B/C class divisions separate accommodation from high-risk spaces
