## Minimize risk of fires in hidden areas 

**Remember:**
- Hidden areas maybe
- on main deck / on lower deck /  between decks
- Above ceilings, behind side panels, below cargo hold floor, dedicated compartments, equipment bays ..............
- Efficient Fire Protection is an overall approach and  requires dedicated to type solutions
- Passive protection (materials & construction)
- Active protection system (detection & extinguishing)
- Installation of not required automatic detection systems may additionally support the crew
