Evolução dos regulamentos relacionados à proteção e combate a incêndios: estudo de caso dos sistemas hidráulicos em uma edificação residencial multifamiliar no estado da Paraíba

Abstract

In the 1970s, major fires hit buildings in Brazil, which until then had no comprehensive regulations regarding firefighting and prevention. From this perspective, the need arose to create norms and regulations, as well as the integration of the Fire Department, aiming to ensure the safety of the population and of the buildings. Paraíba has gradually followed this movement, implementing regulatory measures over time. The objective of this paper is to analyze the evolution of the rules and regulations for firefighting and prevention in the state of Paraíba, and to present a case study of a multi-family residential building located in the neighborhood of Jardim Oceania, in the city of João Pessoa/PB, focusing on the hydraulic systems for firefighting and prevention, more specifically on the hydrant system. The building was built 25 years ago, following the legislation in force at the time, represented by Decree No. 5792/1973 of the State Government. From the study, it was concluded that the main changes from the enactment of the State Law No. 9.625/2011, were related to the use of fire pumps, the flow parameters of the system, pressure in the pipes and their respective diameters.
