Geographic Information System and Multi-criteria Analysis as a fire risk assessment in heritage site

The fire prevention in the cultural heritage of protected cities, which can be handled by Fire Engineering, receives as support for a better confrontation of accidents, the complementary use of the Geographic Information System - GIS, with the Multicriteria Analysis Method - MCA, using variables from traditional fire risk analysis methods: Gretener, Chichorro, EbraFire and Arica. These are selected, quantified and weighted according to their greatest contribution to the site’s vulnerability. Knowing deeply the variables that interfere in a process becomes fundamental for decision making. Hence the importance of the form prepared for the technical visits, and later the creation of the attributes table, designed to organize the data of the chosen location.
The advantage of this unique and integrated proposal is the ease of obtaining visual answers, through maps, facilitating the interpretation and understanding of the data collected and judged as more or less vulnerable to a fire. In this investigation, the analyzes were carried out in the blocks around Praça Tiradentes in Ouro Preto and focused on Portuguese colonial architecture, characterized by the contiguity of the buildings, the use of wood for structure and for clad the floors and roofs of the buildings, indicating the types of buildings that, in most cases, are vulnerable to fire.
