The Thermos Effect

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 shipSolution

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 musterIn addition; less water = less stability issues, clearing tool for evac

Industrial applications

Nuclear Power PlantsSteel plantChemical industries and refineries

Nuclear Power Plants

Nuclear Powerplants Main Objectives

Initial response stabilize conditions with finite resources before municipal FRS arriveContain the incident within the fire cellPrevent contamination (run off water, gases)Limited ventilation possibilities / undesiredAttack without shut down power supply/transmission

BA operations as last alternative (and in a safer environment)

Specific risks atNuclear Power Plants

Autoxidation (especially insulated pipes)Fire in transformer stationsCable channels (over or under ground)Electrical cabinets and roomsIndoor explosionsCarbon filters and other ventilationBattery roomsRoof firesNon-sprinklered high risk objects

Confidential risks objects

COBRA Acheivements -Nuclear Power Plants

Efficiency: The Cobra offers rapid and efficient intervention

from a safe position – outside the fire cell. 1-2 minutes of Cobra intervention will make a

dramatic stabilizing effect on the situation. Containment:

No inside attack No influence on ventilation No contaminated water run off No breach of security barrier / fire cell

Finite resources: A Cobra attack requires 2 fire fighters and can be

fast at the scene before the full team and all resources arrives

COBRA achivements –Nuclear Powerplants

Integrated approach: If a BA attack and other conventional methods are

necessary, it will be in a safer environment for the BA team if you first start the intervention by using Cobra

Suitability: Dielectric test verified the Cobra for the NPP

environment Attack possible with Cobra without shutting down

power supply

Steel plant, equivalent technology, insurance

solution

Steel plant, example

High fire risk production Smelter site with complex filter construction

High cost for investments and re-investments €4,000,000 invested, re-investment at

approx €10.000.000Heavy investments in sprinkler systems required Approx €700,000 + 10-20% yearly

maintenanceContious production process Great revenue loss if production halts

Cobra achivements – Steel Plant

Insurance company recognize Cobra as technology equivalent for sprinklerInvestment in Fast Response Unit, deployed at local Fire & Rescue Service, availiable 24-7Investment at 20% of sprinkler €140.000 instead of €700.000

Cobra used a handful times, ROI on first use.In addition, Societal benefits from Cobra at FRS

Chemical industries and refineries

High pressure productionProduction stops involve extremly high costsHigh risk and costly incidents Firefighters Environment Revenue loss

Cobra achievemnets - Chemical industries and

RefineriesRelease pressures and fight fires in safe ways From outside With use in combination of robot

Reduce environment impactMinimize revenue loss due to production stops
