Quick assessment of fire hazard in chemical and pharmaceutical warehouses

The evolution of fires in confined space such as chemical and pharmaceutical warehouses is characterized by the complex interaction between the combustion process, the enclosure and occupants, which has to be managed when coping with fire emergency and, more in general, for fire safety. This paper proposes a quick, decision-making tool based on adversity scenarios and more specifically through the definition of four main elements: i) the potential fire spread categories, which describe the potential paths and extents of fire propagation; ii) the thermal load expressed as hot gas layer temperature; iii) the available safe egress time (ASET) for people to leave the enclosure, which is essential for organizing people evacuation; and iv) other specific hazards. The proposed tool can be usefully adopted to improve the level of information to interested stakeholders (building owner, fire service, etc.) concerning both the fire hazard and the building fire performance. © Copyright 2016, AIDIC Servizi S.r.l.
