“…The accelerated pace and increase in production processes, as well as urbanization in modern conditions, are inseparably connected with the use of energy-intensive technologies and hazardous substances that increase the potential threat to human health and life, the environment and the material base of production [1,2]. The number of technological accidents and disasters, among which the leading position is occupied by fires, is constantly growing, so today most developed countries, including Russia, are moving to a security strategy based on the principles of the prediction and prevention of technological accidents [3][4][5].…”

The problems of the fire safety of oil and gas facilities are particularly relevant due to the increasing complexity of technological processes and production. Experimental studies of steel structures with three different types of plasters are presented to determine the time taken to reach the critical temperature and loss of bearing capacity (R) of the sample, as a result of reaching a rate of deformation growth of more than 10 mm/min and the appearance of the ultimate vertical deformation. The simulation of the heating of steel structures showed a good correlation with the results of the experiment. The consumption of the plaster composition for the steel column was predicted, which allowed a 38% reduction in the consumption of fireproofing. It was found that to obtain the required fire resistance limit, it is necessary to consider the fire regime and apply plaster compositions with a thickness of 30–35 mm, depending on their thermal characteristics. The dependence of thermal conductivity and temperature on density is obtained, showing that the use of plaster compositions with a density of 200 to 600 kg/m3 is optimal to ensure a higher fire resistance limit. It is shown that the values of thermal conductivity of plaster compositions at 1000 °C are higher by 8–10% if the structure is exposed to a hydrocarbon fire regime. It is shown that the values of the heat capacity of plaster compositions at 1000 °C are higher by 10–15% if the structure is exposed to a standard fire regime.

“…Early fire alarms monitor some features displayed in early combustion behavior for warning, so that more time and proper measures can be taken according to the actual situation to avert or minimize losses. In terms of the whole firedeveloped process that is composed of incipient, growth, fully developed, decay, and burned-out stages [30], early fire alarms mainly play a positive role in the incipient stage and growth stage. Traditional fire management including additive flame retardant (inhibition of flame spread or self-extinguishing) and firefight methodologies (sprinkler systems [31], water spray systems [32,33], or water mist [34]), takes effect primarily after extensively fire propagation, implying the "early" in "early fire alarms."…”

Early-stage fire-warning systems (EFWSs) have attracted significant attention owing to their superiority in detecting fire situations occurring in the pre-combustion process. Substantial progress on EFWSs has been achieved recently, and they have presented a considerable possibility for more evacuation time to control constant unintentional fire hazards in our daily life. This review mainly makes a comprehensive summary of the current EFWSs, including the working mechanisms and their performance. According to the different working mechanisms, fire alarms can be classified into graphene oxide-based fire alarms, semiconductor-based fire alarms, thermoelectric-based fire alarms, and fire alarms on other working mechanisms. Finally, the challenge and prospect for EFWSs are briefly provided by comparing the art of state of fire alarms. This work can propose a more comprehensive understanding of EFWSs and a guideline for the cutting-edge development direction of EFWSs for readers.

“…The ambient temperature during the experiment was 18 °C, with a northern gust of minimal wind speed. In the experiment, 3 fire stages are experienced sequentially, namely the initial growth stage, the fully developed stage, and the decay stage [38]. In relatively enclosed building fires, there is also a flashover stage.…”

In this paper, the firing process and structural failure behavior of outdoor mechanical car parks are innovatively investigated under diverse conditions, leveraging fire experiments, FDS fire simulation, and finite element simulation. The fire experiments reveal the intricate interplay between flame spread and airflow, highlighting the enhanced risk of fire propagation among adjacent spaces. The temperature profile, mirroring the fire’s lifecycle, is delineated into three distinct stages: initial growth, full development, and eventual decay. Notably, full-scale fire simulation in FDS validates the experimental outcomes, underscoring the scalability and reliability of our scaled-down experiments. Furthermore, finite element simulations offer a profound understanding of structural safety in various parking spaces during a fire. Critically, the susceptibility of columns to failure underscores the imperative need for enhanced fire prevention measures in column design, representing a significant advancement in fire protection engineering.
