The Cutting Extinguisher

coldcut™ cobra concept

Safer FirefightingEfficient & Effective FirefightingSaving Environment & Minimizing Collateral Damages

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)

Key performance – Trained personnel

Technique is the practical knowledge of the method, tactics is how the technique is used. Thus, training in technique and tactics are essential for crew to achieve top performance

To accomplish the full effect of the cutting extinguishing method, timing is of essence. Thus, all links in chain of decisions must know, and consider, the possibilities of the method, tactics and technique, to make the right decisions at right time

1: Officer evaluates (RISK ASSESSMENT) the situation while the cobra attack initiates…

3: PPV is prepared together with the hose for the oncoming BA attack…

2: The BA team leader leads the cobra attack and evaluate the situation regularly (Thermal Camera-SCAN)…

4: After a total of 3 minutes COBRA ATTACK the BA attack initiates together with PPV into a cool, smokeless and safe environment…

5: The fully evolved villa fire was extinguished 8 minutes later with a total of 180 liters water (no water damage).

Cutting Extinguisher Method Procedures described in a real house fire, SE 2011

1: The Officer in charge at the

incident scene is also

responsible of the work

conditions for the personnel. He

initiates a COBRA ATTACK

almost immediately on arrival at

the scene.

This in line with buying time

through rapidly cooling the fire

gases, break the fire

development and get in control

of the fire

1. Officer Assessment – Cobra Attack

2: The BA team leader evaluates

the situation with THERMAL

CAMERA together with fire

behavior basics. Now he’s in

charge of the COBRA ATTACK,

supported by his two BA crew…

The BA team leader constantly

evaluate the situation to judge

when and how to change the

tactics.

Workflow from a real life villa fire, Sweden 2011

2. Thermal Camera Scan

3: During the ongoing

COBRA ATTACK, the PPV

fan and the hose/s for the

BA attack are prepared.

The incident manager

gets in control of the fire

and may assess

conditions regarding BA

attack or other actions…

3. Preparation PPV and BA-attack

4: After assessing temperature with

Thermal Camera, the BA-group can

initiate a BA-attack after only 3

minutes of COBRA ATTACK. The

temperature is now approx. 100 C,

thus a safer situation regarding

temperature, risk of back draught,

visibility, etc.

At the same time the BA-group

enters, the outside crew break the

windows and turn on the PPV fan to

evacuate the smoke/steam.

4. BA-attack supported by PPV

5: Using the Cutting Extinguisher Concept; Cobra, PPV, Thermal Camera and BA-attack, approx. 8 minutes from arrival, the fully evolved compartment and construction fire is put out in a safe way. Only 180 liters of water was used and no water damage was found.

5. Rest value evaluation

Critical success factors of Northampton FRS case

Search for alternative methods initiated by unacceptably high number of fatalities in the UKStrong senior level supportAdd technology and method rather than replace leads to acceptance among crewHighly dedicated implementation plan – 6 units first year (rather than buy one for evaluation)High focus on training and methodsCost cutting pressure but rational investmentsNow forefront of UK modern firefighting and Center of Excellence in trainingCobra fitted on 19 out of 23 appliances
