Medidas compensatórias de prevenção de incêndio para escada enclausurada: estudo de caso em edificação hoteleira

Abstract

In answer to concerns raised by fire-related tragedies that involve the non-observance of necessary technical requirements and to ensure measures of prevention and combat of fires in buildings and establishments, several laws and normatives were developed by authorities. In this context, emergency exit projects have gained notoriety for being a system that ensures, safely and satisfactorily, the evacuation of all members of the public present in an establishment quickly. This work aims to comparatively study the stairway-based emergency exit enclosed in the CBMRS Technical Resolution n.° 11, part 01/2016 in a case study of a hotel. For this, a case study of a hospitality establishment in the municipality of Rosário do Sul was done. The methodology applied was a document-based research approach, which consisted of a revision of the existing literature on the theme, as well as an analysis of the aforementioned normatives, and of relevant current legislature. After an analysis of the literature and establishment in question, compensatory measurements were proposed such as the installation of fire doors in the existing stairways, exchanging the existing doors that allow access to the stairways for fire doors; installation of fire doors in public areas to protect the stairways to ease the containing of the propagation of fire and smoke as well as the removal of guests. Another proposal was the construction of an external metallic open stairway to facilitate public evacuation. In conclusion, the compensatory measures proposed in this case study maintain their validity as there were no alterations in the requirement of a closed stairway for the hotel in question, which has a height of 6,12 m.
