“…The delivery of an air jet can facilitate the combustion of compacted materials 57 – 59 . The routing of exhaust gases and the cleaning of passageways using PPVs are extinguishing methods known and described, for example, by Alianto et al 60 . In contrast, the cooling of objects heated by high temperatures is described by Madrzykowski and Kerber 61 and Giełżecki and Wolański of the protective clothing of firefighters 62 .…”

Positive pressure ventilators (PPV) used by 97.7% of officers of the National Fire Service in Poland, are characterized by work that is not in line with the expectations of the firefighters. In order to improve the technical and operational features of these devices, a survey was conducted among 25,000 eligible firefighters, identifying the application of these devices, problems in use and expected development directions. A total of 682 officers voluntarily completed the survey. Based on their findings, it was determined that ventilators are most often used to smoke out buildings after or during a fire. Mentioned problems when using these devices were mainly noise (78.2%), exhaust emissions (68.5%), and impediments to mobility through the device’s relatively heavy weight (40.2%). Other inconveniences were mentioned by less than 20% of firefighters. Polish firefighters expect the development of these devices mainly in terms of the above-mentioned features (noise reduction (81.7%) and reduction of the weight and size of the ventilators (about 50%)). Other expectations relate to the improvement of smoke removal in buildings: increasing the efficiency of smoke removal (46.4%) and efficiency regarding the rate of smoke removal in a building by increasing the size of the incoming airflow from the building’s surroundings (33.2%). About 15% of firefighters expect changes in the operation of the ventilator itself, that is, an increase in the effective operating time (electric ventilators) and an increase in the device’s uptime. The aim of the article is to identify the issues encountered during the operation and to indicate the expected direction of development for PPV by users. This information can be used by engineers to initiate new development work on these devices.

“…This means that smoke was more likely to reach that node first, reflecting the degree of susceptibility to smoke propagation among the nodes. In the table, it can be seen that the smoke content of the ignition floor was ranked in descending order as (1,4), (1, 3.5), (1,3), (1, 1.5), (1, 5.5), (1, 1), (1, 2), (1,5), (1,6), and (1, 0). In summary, the ignition room had the highest smoke content, followed by the adjacent corridor, adjacent rooms and corridors, other rooms, and finally, the staircase.…”

“…The smoke content of the second and ignition floors differed. On the second floor, the smoke content was ranked in descending order as (2, 0), (2, 5.5), (2, 3.5), (2,5), (2,6), (2, 1.5), (2,4), (2, 3), (2, 2), and (2, 1). Based on the analysis, the smoke content was ranked in descending order as highest in the staircase, followed by the room near the staircase in the corridor, the rooms in the middle and near the staircase in the corridor, the middle rooms far from the staircase, and finally, the rooms far from the staircase.…”

The primary objective of the current fire protection system in high-rise buildings is to extinguish fires in close proximity to the detectors. However, in the event of rapidly spreading fires, it is more effective to limit the transmission of fire and smoke. This study aims to develop an IoT-based real-time pre-response system for high-rise building fires that is capable of limiting the spread of fire and smoke. The proposed system collects fire data from sensors and transmits them to a cloud computer for real-time analysis. Based on the analysis results, the cloud computer controls the actions of alarm devices, ventilation equipment, and fine water mist nozzles. The system can dynamically adjust the entire system’s behavior in real time by adopting pre-response measures to extinguish fires and limit the spread of fires and smoke. The system was tested on a simulation platform similar to actual high-rise buildings to evaluate its impact on fires and smoke. The results demonstrate the system’s effectiveness in extinguishing fires and suppressing the spread of fires and smoke.

“…Fire risk assessment is a basic way to reduce and control fires in high-rise buildings [17]. The development of early warning indicators to prevent major accidents-to 'build safety'-should rest on a sound theoretical foundation that includes basic concepts, primary perspectives, and past developments, as well as an overview of the present status of fire safety and ongoing research [18].…”

The purpose of this paper was to develop a fire index system for measuring the compliance of high-rise residential buildings with fire requirements in the Emirate of Sharjah, and also to develop an index system for measuring the fire response efficiency, which is linked the two indexes, and the higher the compliance rate, the greater chance of a successful response. The two systems depend on the automation of the firefighting system management processes using the techniques of the fourth industrial revolution, and they were developed based on consultation with subject matter experts in the field and used multiple methods, such as the analytic hierarchy process, failure mode effect, criticality analysis, and Delphi techniques. The main criteria of the indexes were identified as the fire risk assessment, fire suppression system, fire accident management, fire alarm system, fire extinguisher, employees, residents, service rooms, lifts, gas connections, waste, housekeeping, and evacuation facilities. Each main criterium was detailed in the sub-criteria and weighted to achieve the index for each sub-criteria based on the fire legislation in UAE, the fire response index (developed based on the high-rise building fire index), the category of the building in terms of floor numbers, and the distance between building and the fire station. The two index systems can contribute to improving emergency preparedness in high-rise residential buildings in the Emirate of Sharjah and are also considered as measurement indexes for compliance with fire requirements in the Emirate of Sharjah.
