Fire Suppression
CO2 / N2 Inerting + Fine Water Mist Suppression
Fire suppression via CO2/N2 inerting + fine water mist, avoiding chemical agents that contaminate closed-loop atmosphere.
Purpose
Fire suppression via CO2/N2 inerting + fine water mist, avoiding chemical agents that contaminate closed-loop atmosphere.
Context
Child of L2-HAB-FIRE within the Lunar Ark system
Principles
- ▸CO2/N2 inerting reduces O2 below combustion threshold
- ▸Fine water mist for cooling
- ▸Per-zone suppression activation
- ▸Atmosphere recovery after suppression
- ▸Closed-loop with L3-ISR-VOL-STORE
Typical implementations
- ▸ISS portable fire extinguishers
- ▸Industrial mist suppression
- ▸Marine fire suppression
Lunar considerations
- ▸No chemical agents (contaminate closed atmosphere)
- ▸Water mist + inert gas combination
- ▸Coordinated with L3-HAB-ATMO recovery
