3. Introducing ColdFire Agent – The Heart of the Fire Extinguisher

Why use Cold Fire™?
It's a non-toxic, non-corrosive product and can be dumped directly into booster tanks with no need to flush out lines. It has indefinite shelf life when stored in closed containers. Its thermal insulation capability prevents re-ignition when properly applied.
Is Cold Fire™ hazardous to fire fighters?
No, Cold Fire™ extinguishing agent surpasses other products on the QPL in terms of health, safety hazards and use restrictions.
Was Cold Fire™ developed primarily for fire suppression?
Cold Fire™ was developed to provide the fire fighting industry with an efficient and effective fire-fighting agent that not only extinguishes fire quickly, but also does so without harming the environment, fire fighters, and fire victims. Cold Fire™ was developed with enhanced safety and future generations in mind.
How does Cold Fire™ work?
To understand how Cold Fire™ works, you must first understand the basic structure of fire. In order for a fire to be created, three components are necessary: fuel, oxygen, and heat. These three components form what is called a "fire triangle". Most agents extinguish fires by breaking down one leg of the fire triangle, heat and fuel. Cold Fire™ is considered to have 6 times the penetrating capability of water. This characteristic, coupled with its extraordinary capability to absorb heat, allows Cold Fire™ to penetrate a fire faster, absorb the heat, and bring the fuel source generating the fire under its flash point more quickly. Cold Fire™ also works to encapsulate the fuel source and its vapors and simultaneously begins to break down the molecular structure of the hydrocarbon fuel source preventing re-ignition.
