“…Однак, ГУС з амонійними каталізаторами гелеутворення створюють менш міцні шари гелю, з невисокою адгезією до твёрдих поверхонь, які при нагріванні значно розтріскуються та можуть зсипатися, як порошок. В роботі [14] вдалось створити мобільну установку пожежогасіння ГУС, яка була встановлена на візку зі спеціальними колесами для здолання різних перешкод (наприклад, сходових маршів). Випробування цієї установки показали високу її дієздатність при гасінні нетрадиційних пожеж, до яких можна віднести пожежі в метрополітенах, де на шляхах руху пожежних-рятувальників існують перешкоди у вигляді шпал і напівшпал в тунелях і на станціях метро.…”

The effectiveness of extinguishing fires in the undercarriage space of cars at subway stations has been increased due to the use of a special trolley for supplying gel-forming compounds to hard-to-reach places under subway cars. In order to ensure the delivery of the gelling system to hard-to-reach places under the subway cars, it is proposed to use a special cart that moves inside the main track of the subway in the deepened tray of the water collector, thanks to a cable winch on the «pull-push» principle with an autonomous electric reversing drive. To confirm the effectiveness of extinguishing, on a special stand that allowed changing the position of the model hearth in space, to the position of the conventional ceiling-floor, comparative experiments were conducted for three types of the most common fire extinguishing agents, with the determination of the average values of the time and consumption of fire extinguishing agents for fire extinguishing, with at different angles of inclination of their submission. It is recognized that the use of gel-forming compounds when extinguishing equipment elements in the undercarriage space helps to reduce extinguishing costs and allows to extinguish the fire under the car 2,5 times faster. It was established that the change in the angle of inclination of the burning surface significantly affects the effectiveness of extinguishing with water and fire-extinguishing powder. The obtained data confirm the expediency of creating special carts for undercarriage extinguishing using fire-extinguishing gelling compounds. The obtained results are useful and im-portant, as they confirm the increase in the effectiveness of extinguishing the weighted space with gel-forming compositions, reflect a reduction in times of time and consumption of fire extinguishing agent when using gel-forming compositions. The use of a special weighted extinguishing cart with gel-forming compositions allows automated remote extinguishing in hard-to-reach places of the weighted space, which significantly increases the safety of rescuers when extinguishing such fires.

The research has been conducted to determine the safe residence time for people in a room where the composition of the gas environment has deteriorated due to fire. Carbon monoxide, which is produced by fire, has been found to be lethal for human life and health. Determination of safe time was made based on the study of the composition and amount of fire load in premises and buildings, physical and chemical properties of carbon monoxide, and its effect on the human body. The graphical dependences of the concentration of carbon monoxide in a room, as a function of time, were obtained for eight variants. The results allow authors to determine the possible residence time of a person in a building during a fire before the lethal concentration of carbon monoxide occurs. Studies made it possible to determine the safe residence time of people in a building on fire in a calculated way and to compare it with the normative indicators of the onset of lethal concentration of carbon monoxide in the air. The results obtained determine the safe time during which a person can escape from the building on fire.

“…Since the early 1990s, 82 % of fires in the world have been extinguished with the use of water [1]. Liquid water-based fire-fighting means have found the most common application owing to availability and convenience of transportation to the place of a fire.…”

“…However, it should be emphasized that despite all the advantages of water, it has a major drawback, which is related to its huge consumption when flowing down inclined surfaces and leading to needless flooding of sites located below, which eventually decreases its fire-extinguishing effectiveness [1].…”
