APPLICATION OF EMERGENCY ON BUILDING FIRE USING ANT COLONY OPTIMIZATION METHOD BASED ON ANDROID

Fire and Rescue Service is an agency to handles fire problems, i.e building fires. Fire and Rescue Service of Pekanbaru is an agency to handles fire problems in Pekanbaru where the service receives information about a fire incident quickly and responsively. Fire incidents can occur anywhere, in any location, both easy or difficult access, but the Firfighter Team must be prepared in every conditions. The problem is that not all fire incidents occur in easy access places by firefighters. The incidents sometimes occur in difficult places to reach and unknown location, firefighter have to use maps to find the location. It will be wasting time to find unknown location and took a long time to arrive. The solution of this problem is to build an android-based application that can be used as a fire incident report, which is connected in one application, so residents can report through an application automatically provides the coordinates of incident. The application of Ant Colony Optimization method in finding fire locations makes it easier to hasten in searching fire locations and can be used by the public in reporting fires to Fire and Rescue Service of Pekanbaru to be processed quickly.

Influence of Courtyard Size on Stack Effect During Building Fires

This paper studied the stack effect in courtyards in buildings through the pressure difference between the top and the bottom in the courtyard through three-dimensional (3D) numerical simulations, which would provide engineering guidance for the fire protection design of courtyards in buildings. During the fire, the stronger the stack effect was, the pressure difference between the top and the bottom was more significant, the fire smoke reached the top of the courtyard more quickly, and the temperature and the smoke concentration at the top were influenced in a shorter time. The influence of the size of the courtyard in the stack effect was investigated. It was found that the stack effect was linearly negatively related to the width of the cross section W and the length of the cross section L, exponentially negatively related with the area of the cross section A, while it was exponentially positively related to the height of the courtyard H. The change in the walls without windows (W) affected ΔPmax and the stack effect more significantly compared with the change in walls with windows (L). When L/W ≤ 1, the stack effect was strengthened as L/W increased; when L/W > 1, the stack effect was weakened as L/W increased. The stack effect was the most significant when L/W = 1.

Research on High-rise Building Fire Early Warning System Based on Multidimensional Data Fusion

With the rapid development of urban construction and the increasing number of high-rise buildings, many problems have arisen, one of which is fire. High-rise building fires are developing rapidly, and it is difficult to extinguish them, which causes great losses and seriously threatens people’s safety in production and life. Early warning of high-rise building fire is an important means to prevent fire. In this paper, aiming at high-rise building fires, the causes of high-rise building fires in 2019 are analyzed statistically, and the causes of high-rise building fires are summarized. An intelligent early warning system of high-rise building fire based on multi-dimensional data fusion is proposed. Based on the actual forecast data, the early warning system based on multi-dimensional data fusion is analyzed through Matlab simulation, thus verifying the feasibility and reliability of the established fire early warning system. The research results have certain guiding significance for high-rise building fire warning.

Community/Public Health Nurses’ Awareness of Residential High-Rise Fire Safety issues

High-rise (HR) building fires remain a tragic cause of preventable injury and death in the United States. Recent incidences of HR building fires have served as high-profile reminders of the persistent threat that HR fires pose to public health. Fire safety is an important aspect of household emergency preparedness addressed by community/public health nurses (C/PHNs). This study aimed to address a gap in the literature regarding C/PHNs’ awareness of fire safety for people and families who reside in HR buildings. A descriptive qualitative study using key-informant and focus group interviews was conducted involving C/PHNs ( n = 19) in Honolulu, Hawaii. Qualitative data analysis revealed three main themes related to this issue: (1) C/PHN awareness of HR fire safety issues, (2) C/PHN perceived barriers for HR building occupant fire safety, and (3) C/PHN suggested strategies to address HR fire safety for occupants. Findings highlight how more needs to be done to assure that C/PHNs are adequately prepared to work with occupants of residential HR buildings on matters related to fire safety.
