CREATION OF A PORTABLE FOAM GENERATOR WITH PRACTICAL RESEARCH CONDUCTED

Abstract

The article describes the process of modeling and creating a compact portable foam generator of medium multiplicity with geometric and dimensional parameters that allow for the use of air-mechanical foam directly during reconnaissance without complicating circumstances that arise during reconnaissance with a gas and smoke protection service when it is necessary to supply air-mechanical foam without a foam generator, which is not included in the minimum necessary list of firefighting tools and devices. Generally, the use of foam generators by the gas and smoke protection service during fires is a common practice and constitutes typical actions in case of fire incidents. However, there is one particular aspect in the use of generators - their weight and geometric dimensions, which may restrict the movement of personnel in relatively confined spaces such as cable tunnels, basements, and underground structures. Therefore, greater attention should be paid to the use of foam generators with medium multiplicity. The foam isolates the combustion zone from flammable vapors and gases, as well as the combustible surface of the material from the heat emitted by the reaction zone. It penetrates well into the premises, overcomes turns and climbs, quickly fills the volume of the room, displaces combustion products heated to high temperatures, thereby reducing the temperature in the room. To ensure instant response to the situation during reconnaissance with a gas and smoke protection service, equipment should be provided that allows for confident response to complex tactical tasks for the fire suppression commander, making informed and decisive decisions regarding reducing the likelihood of emergency situations and reducing the percentage of human and material losses. The motto of a rescuer is "prevent, save, help." This article describes a useful model that reduces the decision-making time for the fire suppression commander at the end of reconnaissance, the time of initiating the first fire extinguishing nozzle, the time of fire localization and extinguishment, which increases the likelihood of saving human lives from fire hazards. Keywords: compact medium expansion foam generator, air-mechanical foam, gas and smoke protection service.
