FIRE – LCA model for environmental decision – making
Résumé
Fires have been a part of our society both in term of controlled fires, or combustion, for heating purposes and uncontrolled accidental fires. Accidental fires cause a substantial amount of damage both economically and in terms of human lives. However, we need to better understand the relationship between these phenomena, and develop scientifically sound tools for identification of the hazard, the assessment of risk, and the implementation of fire prevention and protection measures. Such work is just beginning within ISO/TC92/SC3 under its mandate to consider not just the local effect of fire effluent on people but also its effect on the environment. A very limited number of papers have focussed on the environmental issues of fires consequently the environmental impact of fires has only recently come under scrutiny. It is, therefore, important to find a method which includes all the impacts of fires. Recently a novel LCA model , the so called Fire-LCA model, was developped where the environmental effect of fires was incorporated into the overall treatment of the environmental impact of the product under study. The Fire- LCA model is essentially equivalent to a traditional LCA approach with the inclusion of emissions from fires as the most important modification. This model will therefore include modules to describe the fire behaviour for the different types of fires. Fire statistics are used to quantify the amount of material involved in the different cases. In addition, the model should also include modules to take into account the production of replacement materials that are needed due to the shortening of lifetime that the fires have caused. If possible the model should also include modules for the handling of the fire extinguishing process and the decontamination process. This paper presents an application of the Fire-LCA model to a refinery which is a system with a high level of fire safety.
