“…In the other study by [5], pyrolysis analysis was used to examine the incineration characteristics of polystyrene isolating foam board. This study analyzes the temperature, smoke, and other characteristics of the fire setting when a fire occurs in a cold storage facility and forms a water mist to conduct an experiment on fire extinguishing.…”

Variations of nozzles are studied for Compressed Air Foam Systems (CAFS). The CAFS is a self-contained fire suppression system with the capability of injecting compressed air into the foam solution to create a dense mist. Even though this type of foam has a tighter, denser bubble structure that allows it to adhere to vertical and horizontal surfaces and penetrate the fire more deeply before the bubbles burst, thereby making it more effective, the nozzle of CAFS is weak. The experimental study has been done in order to find the expansion ratio of the nozzle. Four sizes of diameter nozzles are 5 mm, 10 mm, and 20 mm, and three holes are 20 mm. Nozzle diameter size has a correlation with bubble size. The highest expansion ratio is found in the nozzle with three holes 20 mm in diameter. It is followed by a nozzle with a 20 mm diameter, then a 10 mm diameter. The last finding is a nozzle with five diameters. The other founding is the linear correlation between nozzle diameter size and bubble size. But it is on the other way than the correlation between nozzle diameter and bubble size. The shorter the nozzle diameter, the faster the fire extinguishing time.

The main objectives of this research are to analyze the spatial distribution of petroleum stations in the Nile City/Al-Mahaweel District using multi-criteria analysis based on Geographic Information Systems (ArcGIS 10.8). The study aims to provide a clear picture of station distribution and spatial variations, explain the underlying reasons for this distribution for each station, and assess the spatial compatibility with planning standards and site requirements. The research also aims to enhance safety and security by optimizing station locations and mitigating potential risks. However, a research problem indicates that the distribution of stations in the Nile City/Al-Mahaweel District needs to adhere to planning standards. Stations are primarily located outside the city center, resulting in a need for more service provision for residents and visitors. This distribution poses environmental risks and compromises spatial safety. The research hypothesis suggests that adopting sustainable and analytical planning standards can enhance station efficiency, achieve optimal distribution, ensure spatial safety, and mitigate risks. The study was conducted in the Nile City/Al-Mahaweel District, where three fuel stations are located outside the municipal boundaries, with no stations within the district. Various assessments were made concerning fuel stations, including detailed maps of the actual conditions, hypothetical geographic maps, standard distance distribution maps, directional distribution maps, allocation area maps, and petroleum stations in the city. By comparing the current status of petroleum refueling stations with the standards and site requirements, a multi-criteria spatial analysis was conducted using seven essential criteria: minimum distance between the station and service facilities, residential areas, population density, community services, road networks, accessibility distance, and distance from power lines. Key findings of the research indicate that station distribution in the study area adheres to the established standards, criteria, and regulations set by relevant official bodies concerning safety and security. However, some fuel stations only partially comply with all criteria, while others exceed certain parameters. Proposed locations for fuel stations (Station A with an area of 5000 m² and Station B with an area of 4500 m² ) were determined based on planning standards to enhance the spatial distribution efficiency of stations and improve service provision to meet demand. Particularly, the Nile City/Al-Mahaweel District, which lacks fuel stations, relies on stations outside the municipal boundaries due to administrative divisions from the main district, resulting in insufficient station distribution that caters to the population's needs. The multi-criteria approach proves highly effective in determining the optimal number and location of petroleum stations within the city and district.

“…The institution in charge of firefighting and rescue receives the message and some special devices help to decode the data received to know what was going on in a particular building. The final decoded message is interpreted as a fire notice, fault annunciation, or test message so as to know what to do if the message is informing about fire occurrence (Yin et al, 2022). This issue is very critical and can be solved by using intelligent notification and automatic feedback systems to activate local fire extinguishers while waiting for the fire department to provide emergency support.…”

The functional buildings and other sensitive places in Rwanda are highly affected by sudden fire outbreaks caused by reckless human actions and unexpected incidents resulting in highly valuable property damage and human lives losses. To tackle this problem, security and safety measures against unexpected fire outbreaks in real-time with the help of modern technologies are required. In this study, the real-time smart fire outbreak detector and extinguisher system were designed for monitoring and controlling the sudden fire outbreak inside a building using Internet of Things (IoT) technology. In this system, the smart sensor node was designed based on an ESP-8266 module with Gas, temperature, and flame sensors for fire outbreak detection as well as an automatic fire outbreak location finder with an extinguisher system. It also employs a smartphone with a customized mobile app (Blynk Application) that provides the interface between the user and the system through a platform. As a result, around 655 ppm of smoke was detected which is the indicator for abnormal conditions together with all other values greater than 400 ppm. The developed Blynk App successfully linked the building and remote operator for notification about the fire condition on smartphones for decision making.
