More bang for buck!
Pooling and SharingSmart defenceSocietal changes in terms of Safety & SecurityUnorthodox situations and missionsLess fundsImplies longer life spans of vessels, less crew, more capabilities
Mitigation of austerity = mitigation of backdraft?

Unique concept
Cuts through virtually any material Suppresses, cools and extinguishes fires from safe position outside of fire roomMobile, high pressure water mist with minimal use of waterThe only method with combined capabilities (penetrating, extinguishing, mobile, minimum of water)

The Thermos Effect
![Page 17: Cobra Cutting Extinguisher at MAST Confex 2012](https://reader034.vdocuments.net/reader034/viewer/2022042602/558c1ea6d8b42ac7528b4787/html5/thumbnails/17.jpg)
Light Weight Composite Structures
Problems “Thermos effect” - Containing fire not an option
Boundary cooling not feasible - Must fight fire in the compartment
How to handle breeched fixed installed fifi systems?
Low classified fire zones? Concealed areas?
BA-attacks adding oxygen, high risk procedure for crew and ship
Solution Cutting extinguisher as standard procedure and for redundancy
Safe position – outside of the fire zone
Fast deployment and boundary cooling from inside of thermos
Mitigates back draught
Buys time for BA to muster
In addition; less water = less stability issues, clearing tool for evac

Enhanced Swedish Navy FiFi Tactics - SOP
Step Measure Tactic Time Personnel required
0. Preventive Fixed systems, insulation,training, awareness, etc.
1. Early detection
Assessment of situation, fire alarm
Immediate 1
2. First Attack,Containment
Portable extinguisher, seal fire zone, I report to XO
Immediate after 1. 1
3. Second Attack,Cobra attack
Break fire development.Boundary cooling from inside at CAPs (S) and fixed systems. Creating time for BA-attack
Immediate after 2. 2
4. BA-attack Safe re-entry procedure, extinguish fire. Cobra attack crew supports BA crew
Effect of 3 in fire zone, & BA crew mustered
2+3
![Page 24: Cobra Cutting Extinguisher at MAST Confex 2012](https://reader034.vdocuments.net/reader034/viewer/2022042602/558c1ea6d8b42ac7528b4787/html5/thumbnails/24.jpg)
Solution to many issues – Swedish Navy
Efficient intervention from a safe position
1-2 min. Cobra attack makes dramatic effect on the fire development
Intervention without ventilating or entering into the fire zone
Boundary cooling from inside the “thermos”
Requires 2-3 crew and can be introduced prior BA attack muster
Safer environment for the BA-attack and re-entry procedures
Mitigates back draught / flash over
Less water used; less stability issues, less collateral damage
Excellent system for redundancy for breached fixed installed systems
Excellent for out of reach areas; voids, cofferdams and containers
Easy to introduce to present fifi procedures, easy to learn and practice
Less impact on the mission as a whole
Cost efficient solution for retrofitting enhanced fire protection
Can be used as a clearing tool, especially on composite vessels
