Mangotinho e hidrante em uma edificação escolar: análise da viabilidade técnica e adequação operacional

Abstract

This study presents a comparative analysis between type 2 fire hydrant systems and type 1 fire hose reel systems applied to school buildings, based on the guidelines of the Fire Department of the State of Amazonas (CBMAM) and the Brazilian standard ABNT NBR 13714. The objective was to evaluate the technical, normative, and operational aspects related to the use of each system, assessing their suitability for the context of schools. To this end, a fire safety project was developed for a model school building, including the preparation of calculation reports and the hydraulic design of both systems. The results showed that, although both comply with regulatory requirements, the type 1 fire hose reel system proved to be more practical, faster to operate, and more efficient in the initial stages of fire suppression, key features in environments occupied by untrained individuals. Despite the need for higher-power pumps due to head losses, the system proved to be more suitable for the operational conditions of schools, as it allows for a significantly shorter response time and can be safely activated by individuals without specific training. It is concluded that the fire hose reel represents a viable and effective technical alternative, providing a quicker and more accessible response in emergency situations, thus strengthening fire safety measures in educational environments.
