Beyond the fire triangle – the science of modern-day fire extinguishing

You may be familiar with the concept of the 'fire triangle'. This is the basic rule that for a fire to burn, three factors must be present: heat, oxygen and fuel. To extinguish the fire, all that is necessary is to remove one element of the triangle. Water will take away the heat, for example, while carbon dioxide will remove oxygen.

As with many simplified concepts, the reality is a little more complicated. In fact, a fourth factor must also be present for a fire to ignite - a chemical chain reaction. So the visual representation of fire is not so much a 2D triangle as a pyramid or tetrahedron – a 3D triangular shape with four faces. This fourth factor, the chemical chain reaction, essentially means that there must be sufficient reaction energy between the other three components – heat, oxgygen and fuel – in order to produce ignition. Recognition of this fourth component has led to the development of new methods of fire suppression and extinguishing, helping in turn to prevent the catastrophic damage that fire can cause.

The science of fire suppression

The science of fires and fire suppression

Here at Allsaved, we work hard to keep abreast of the latest advances in science and technology, and always seek to work with suppliers who share a similarly forward-thinking approach.

FirePro is a leading global company that has impressed us with its ability to reinvent traditional methods of fire suppression to offer a revolutionary new product that is now used in 110 countries across the world.

During many years of research and development, FirePro investigated how the chemical chain reaction needed to ignite a fire could be interrupted on a molecular level. The result is a patented solid compound known as FPC, a non-pyrotechnic substance that is based on eco-friendly naturally occurring potassium salts. This compound is condensed into aerosols, and when the aerosols are activated FPC is transformed into a rapidly expanding fire extinguishing agent. FPC works by interrupting the chemical chain reaction occurring in the flame and not by the traditional methods, such as depletion of oxygen, or cooling. FPC works quickly, evenly and efficiently, allowing for significant benefits that conventional fire extinguishing methods cannot offer. These benefits include:

  • Environmental sustainability. The physical and chemical characteristics of aerosol suppression systems mean that they pose no threat to the environment once they are activated. They are ozone friendly and do not contaminate water, air, climatic conditions, animals, plants or micro-organisms.
  • Safe for humans. High concentrations of carbon dioxide in a confined space are highly dangerous, rapidly causing unconsciousness, coma and death. As such, CO2 suppression systems can be deadly if activated when there are people or animals in the vicinity. FirePro's FPC compound poses no such risk.
  • Asset protection. Fire extinguishing agents such as water, foam or powder can damage equipment beyond repair. FirePro's unique compound will not damage property, machinery or electrics.
  • Efficiency. Because FirePro products do not need to be connected to gas or water pipes, they are easy to install and take up less space than traditional fire suppressant systems. The units are modular and can be easily expanded, relocated or altered. They do not require gas cylinders, which further reduces the physical footprint of these systems within a confined space.
  • Durable. The product life span is up to 15 years.

Where can FirePro fire extinguishing aerosol systems be used?

With its modular system and range of products, FirePro is a versatile method of fire suppression that can be used in a wide variety of settings. The smallest units can protect electrical panels or personal computers in offices, while medium to large-sized systems can be used in power plants, including nuclear plants; warehouses; wind turbines; and high voltage control rooms. Take a look at the FirePro website for further details on product applications in all types of industries. 

At Allsaved, we have fitted FirePro aerosol systems for customers in diverse settings; for example, one recent project involved fitting FirePro into a moveable 40ft container housing an electricity generator which is used to warm water for mixing concrete in sub-zero temperatures. You can discover more information about this project on our case studies page.
