Abstract:

In this paper, the influence of catalytic on the extinguishing effect of inorganic salt fire extinguishant has been studied. Results of TG test and burning test indicated that catalytic synergist ammonium tungstate and sodium tungstate can effectively increase the fire extinguishing effect of the inorganic salt fire extinguishant, and sodium tungstate has a better catalytic synergistic effect than ammonium tungstate.

Abstract:

In order to increase the efficiency and the rate of extinction, it was proposed to use extinguishant aerosols to extinguish. Extinguishant aerosols are more comfortable in operation and cheap compared to gas, foam and water fire extinguishing. As for the phlegmative concentrations, it is apparent that all of these substances have different values of phlegmative concentration. The lowest levels of phlegmatic concentration are for extinguishing aerosols, which, due to the developed surface, effectively interrupt chain reactions and perform explosive action.

Abstract:

Phosphate resources are non-renewable and are increasingly depleting. Currently, the primary raw material for commercial ABC dry powder fire-extinguishing agents is a processed product derived from the limited reserves of phosphorus ore. Consequently, there is an urgent imperative to innovate and develop novel types of dry powder fire-extinguishing agents. In this work, a simple physical blending process was utilized to modify the abundant and cost-effective hydromagnesite (HM) powder, which has been proven to be a promising dry powder extinguishant with a pronounced physical cooling effect on

Ammonium phosphate fire-extinguishing agents are one of the best substitutes for halon in many powder media. Here, 11 μm median diameter ammonium phosphate ultrafine dry powder was used as a fire-extinguishing medium.

Abstract:

Water has been known as a substance that can extinguish fires. Water is not only easily sourced from nature, but it has been naturally used to extinguish forest fires because it does not cost anything. However, when rivers, reservoirs, streams, etc. are frozen in winter, it may be difficult to use water for extinguishing. For this reason, other countries are used to fire extinguishing agents that have higher extinguishing performance than water to reduce the extinguishing time and amount of water.

Pulse fire extinguishing was actively developing. There is a wide range of impulse fire extinguishing devices on the market. However, existing standards do not cover the entire class of these products. Hence there are problems with their certification. To date, two standards are approved and in force: GOST R 53291—2009 «Fire-fighting equipment. Mobile and portable fire extinguishing devices with high-speed delivery of fire extinguishing agent. General technical requirements. Test methods», and GOST R 53286—2009 «Fire-fighting equipment. Automatic powder fire-extinguishing installations. Module

Introduction. The article substantiates the use of the depth of fire extinguishing by fire-fighting hoses for estimating the possibility of localization of fire in the management of combat operations in residential buildings. On the basis of the criterion in a generalized form a block-scheme of the generalized algorithm of the decision-making support of the fire extinguishing manager, which makes it possible to determine the possibility of localization of the fire by the available water fire-fighting hoses, is offered.

Abstract:

Using the methods of grenade explosion scattering the extinguishing agent for crown fire saves has been an important remote way for crown fire saves. Scattering the solid agent from explosion is greatly influenced by external environmental and airflow in fire, which results in the low efficiency of extinguishing agent. Dispersion area of grenade scattering extinguishing agent can be calculated through the combination of numerical simulation and experimental determination. On the base of high extinguishing concentration, the structure of grenade is optimized and the efficiency of extinguishing

Abstract:

The fire at the Coupang Deokpyeong Logistics Center has spurred studies to reduce the damage caused by multi-tap electrical fires. One solution is a microcapsule fire extinguishing patch with a built-in fire extinguishing agent. To confirm the efficacy of the fire extinguishing patch in curtailing electrical fires, a complex electrical fire in a multi-tap due to overload and tracking was simulated. In the absence of the fire extinguishing patch, continuous flame discharge occurred as the overcurrent reacted with internal combustibles, resulting in a short circuit due to final tracking and a ri

Liquefied natural gas (LNG) facility accidents typically begin with equipment depressurization, fuel spillage, and subsequent ignition. The effect of a jet fire on other nearby process equipment can lead to a cascading accident. Extinguishing a jet fire in its initial stages will prevent such a scenario. The purpose of conducting full-scale fire tests to extinguish the LNG jet fire using gas-powder fire extinguishing installations was to confirm their fire extinguishing effectiveness. The fire tests were conducted in an open test area with the LNG fire jets directed at angles of 45, 60 and 90

Now-a-days fire disasters are very common it will occur at any time and it may lead to loss of money and human lives. This paper proposes the use of robot to extinguish the fire in its beginning stage of a small flame itself by continuously monitoring the area therefore the fire accidents will be reduced. It is also used to help fire fighters in extinguishing fire in narrow areas and also in hazardous situation so it would reduce the risk of fire fighters in the process of saving victims life. This robot is developed to extinguish the fire in its beginning stage itself.
