Centre for Fire and Hazards Science

Fire is our oldest technology, and was crucial to each step in our development. Fire has given mankind major benefits but has also caused many disasters. Now fire, through controlled burning, provides most of our energy, which in turn causes nearly all the world’s air pollution.

Unwanted fires, ranging from the deliberate "torching" of a car to a major fire disaster resulting in hundreds of deaths, are a growing problem. As more flammable plastic materials replace traditional materials, such as metal, stone, wood, wool and cotton, so the risk increases. Fortunately, unlike wood or wool, manufacturing processes allow fire retardants to be added, to reduce a material’s flammability. Like fire itself, this has advantages and disadvantages. Most materials never get involved in fire, and sustainable recycling and waste disposal is increasingly important. Polymers containing fire retardants may be more difficult to recycle, or may possibly contaminating a batch of recycled material, while effectively fire retarded materials will always be difficult to dispose of by incineration.

Fire is a specialist subject and we are fortunate to have expertise in:

  • Fire science
  • Fire retardancy
  • Fire toxicity 
  • Fire investigation
  • Fire safety engineering

We have a very wide range of facilities and equipment for quantifying fire behaviour and standard testing which is available for research, consultancy and testing.

We will be very pleased to discuss fire problems with you.

Expertise and Subject Areas

Fire science

Fire is the rapid exothermic degradation of a material, characterized by a rapid and often increasing rate of reaction, accompanied by the evolution of heat and light. Partial oxidation results in the formation of solid and liquid aerosols and gases (smoke).

At first, the solid polymer, then the smaller fuel molecules, react slowly with oxygen, generating heat which warms the rest of the material. As they react a low concentration of unstable radicals are formed, capable of reacting billions of times faster than molecules. Radicals are fragments of molecules that can react with other stable molecules, forming even more radicals. This starts a chain reaction and the radical concentration increases. This makes the reaction go faster still, increasing the radical concentration exponentially. When it reaches a certain value, ignition occurs. Flames contain high radical concentrations. Without the initial source of radicals from a flame, much more heat is needed to cause ignition. For sustained burning, the heat fed back from the flame must be greater than the heat required to break down the material, and feed it with enough fuel. For many polymers, the heat of combustion can be up to 20 times the heat needed for polymer breakdown, so once started, it will not stop until it is starved of fuel or oxygen.

Fire retardancy and fire toxicity

Knowing how a material behaves in a fire is a crucial step in reducing the horrifying losses caused by fire. The specialist Fire Research Laboratory has been set up at the University of Central Lancashire (UCLan) in Preston. This has brought together the existing expertise in fire retardancy and fire toxicity which have moved from the Universities of Salford and Bolton to combine with the existing Centre for Fire and Explosion Research produce a Centre of Excellence in Fire and Hazards Science. The Fire Research Laboratory is fully equipped with modern analytical instrumentation and a comprehensive range of small and medium scale fire tests. This will enable the team to pioneer and undertake the development of a new generation of fire safe materials. It will provide a vital service to industrial research and development, allowing improvements in fire safety to be made, before products reach the final, accredited standard testing laboratories. Crucially, it will also provide detailed chemical analysis, presenting a unique insight into how fire retardants work, and how their performance may be improved.

The history of the group’s involvement in fire goes back to 1981, when rapid scanning time-of-flight mass spectrometers with thermal and laser pyrolysis were used to look at the reactive species emanating from decomposing polymers. This approach has evolved into the use of controlled atmosphere and heating rate pyrolysis interfaced to GC-MS for identification of thermal decomposition products.

Much of the specialist equipment at the Laboratory has been designed and developed by our experts over a number of years to gain experimental information towards the above goals. In addition to a suite of laboratory tools for basic decomposition and combustion studies, the Laboratory specialised equipment and facilities, more about this can be found on our facilities pages.

Fire safety engineering (Combustion and explosion)

Advances in combustion, explosion science and fluid dynamics have a significant and decisive impact on progress in fire engineering and explosion safety as well as on many important problems facing modern technology and the environment. This determines the main research areas in our Centre.

  • Accidental fuel releases and their effects on the atmosphere
  • Ignition, Flames structure, stability and acceleration
  • Fire Safety by sustainable design
  • Explosion
  • Modelling, simulation and experimental studies of enclosed and open fires
  • Fire modelling for risk assessment and fire investigation

These research areas cover a wide spectrum of research problems, including new physical and mathematical models of combustion, explosions and related phenomena. It reflects new advances in combustion and explosion science and computational fluid dynamics, which have a significant and decisive impact on progress in fire engineering and create the required fundamentals for the overwhelming majority of applications in fire engineering. These include fires, explosions and other potentially dangerous situations within chemical industry, transportation and storage of chemically active substances, and in the environment. The Centre has also conducted research into large open and enclosed fires and explosions, which is central to the research program of this area. These studies confirm the vulnerability of industrial and civil conurbations with high concentrations of combustibles and lead to a necessity of general studies in hazards, disasters and emergencies. This has resulted in the formation of the second research area.


Unwanted fire has major impact on human society, and our research has been effective in reduce the societal and economic harm from fire.

Examples of impact include:

  • Quantifying fire toxicity
  • Development of more fire safe materials
  • Involvement in international standardisation bodies
  • Public awareness of fire safety

The UCLan Fire Research Laboratory has a very wide range of experimental methods and many years of experience in understanding the burning behaviour of all types of materials, especially in the development of those with improved performance in fire. This accumulated knowledge and research expertise can be made available through general liaison, advice and consultancy services.

The particular areas of expertise at the UCLan Laboratories are:

  • Burning behaviour and relationship between small and large scale studies
  • Decomposition and combustion mechanisms and influence of additives
  • Quantification of toxicants present in the fire effluent
  • Smoke evolution
  • Environmental aspects

A particular thrust of the UCLan work has been to study the component parts of the burning process. This has been achieved by isolating the individual steps (pyrolysis, product formation, oxidation reactions etc.) of the overall combustion, which are studied in detail under carefully controlled laboratory conditions. This approach assists the understanding of the complex mechanisms of the burning and the identification of the precursors supporting flammability, smoke, toxicity etc. so that particular problems can be controlled within the burning process, for example by promoting char formation rather than the release of flammable species at elevated temperatures.

Fire is a complex chemical process which is poorly understood. Using a full range of chemical analysis techniques (GCMS, FTIR, NMR, HPIC, electrochemical cells), and thermal analysis (TGA-EGA, DSC) and rheometric measurements, and bench scale physical fire models (LOI, UL-94, Cone Calorimetry, Steady State Tube Furnace etc.) we have investigated the decomposition of polymers, the structure and formation of chars, and the gas phase products of decomposition and combustion, including quantification of toxic gases and particulates, and early stage fire gases. This has provided vital mechanistic information on the fire retardant behaviour, and the formation of toxicants in fire gases, informing the development of new fire safe formulations for commercial use. The sensitivity of burning behaviour and toxic product yields to different fire scenarios has led to investigation/understanding of the range of test methods for investigation of flammability and fire toxicity.
