This article presents a full-scale fire experiment carried out in a dormitory bedroom in the city of Recife, Pernambuco, Brazil. The experiment was recorded by thermal and conventional cameras, and temperatures were measured at 24 different points within the environment, making it possible to observe the dynamics and behavior of the fire in detail. Among the objects in the dormitory were two identical bedside tables, one of which was coated with intumescent paint. Particular attention was paid to the behavior of this piece of furniture, which, despite being in direct contact with the flames for more than 20 minutes, did not completely burn. Similar experiments are rare in Brazil and in Latin America as a whole, especially with the use of furniture and locally built structures. Understanding the dynamics of this fire, which very closely resembles many local cases, is therefore important to generate data on thermal behavior and overall understanding of the phenomenon. Regarding the specially-treated piece of furniture, its performance was found to be satisfactory, suggesting that such a protective process for furniture may help inhibit the spread of similar fires.
Este artigo apresenta a simulação computacional de um incêndio realizado experimentalmente em um cômodo que reproduziu um dormitório de residência unifamiliar tipicamente incendiada na cidade de Recife (Pernambuco – Brasil). O ensaio experimental deste incêndio é apresentado por Corrêa et al. (2017), e o estudo discutido neste artigo tem por objetivo comparar os resultados de desenvolvimento de temperaturas dos gases obtidos através da simulação computacional com o software Fire Dynamics Simulator (FDS) com as aferições obtidas experimentalmente. Verificou-se que os resultados de temperaturas obtidos através do modelo desenvolvido no FDS foram coerentes com os obtidos experimentalmente. Aspira-se que este estudo auxilie e incentive o uso desta ferramenta em estudos de Segurança Contra Incêndio em Edificações (SCIE).
This article presents the mapping and analysis of fires with dead and wounded people in the Metropolitan Region of Recife (MRR) served by the Firefighters Department from 2013 to 2016. There was an average rate of 1 death per million inhabitants, similar to countries such as Singapore and Vietnam. The weighted number of fires per wounded or dead person results in rates of 0.5 and 1.7 per 100 recorded fires, respectively. These numbers are concerning, especially when compared to rates from other regions in the world. The victims of fires in MRR were shown to generally not be a perceivable problem in terms of common sense, yet they are real and require accurate analysis and effective measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
