A device for preventing or extinguishing a fire in an electrochemical energy storage system comprising storage cells arranged in a storage housing, wherein the energy storage system is connected to a discharge unit for discharging energy from the energy storage system, the discharge unit comprising: at least one anchor, and a drive assembly for driving the at least one anchor to the ground, the anchor being electrically connected to the energy storage system, such when the anchor is driven to the ground, the energy storage system is grounded.

A fire suppression composition includes starch, a pseudo-plastic, high yield, suspending agent, and agglomerating material.

The present specification discloses nontoxic fire extinguishing agent compositions, devices, methods and uses of same that are safe for both users and the environment. In particular examples, the nontoxic fire extinguishing agent comprises a microbial supernatant.

The invention relates to a material consisting of a preparation made from a mixture of ferrocene and an inert flameproof material such as plaster, the material being presented in the form of granules and being suitable for spreading over a hydrocarbon fire in a simple and rapid manner such that, under the effect of the heat from the fire, the ferrocene contained in the granulated material is diffused progressively and homogeneously in a vapour phase over the base of the flames, so as to optimise the combustion of the hydrocarbon and to reduce the emission of smoke and unwanted particles.

The present invention discloses a cooling type dry powder fire extinguishing agent and a preparation method and application thereof, which belongs to the technical field of fire control. Through a static mixing technology, an aqueous solution and a solid hydrophobic material are dispersed and mixed efficiently to form a cooling type dry powder fire extinguishing agent. The fire extinguishing agent is a micron solid particle of the aqueous solution wrapped by the hydrophobic material microscopically, and is in a dry powder state macroscopically, which can significantly reduce the electrical conductivity of the fire extinguishing agent. Meanwhile, a field rapid preparation method is adopted, which can realize real-time preparation. The preparation method is simple and efficient. The technology can be used for fighting a battery fire, has significant cooling and anti-reignition effects and can avoid the problem of electrical conduction of a traditional water-based fire extinguishing agent.

A fire-retardant material comprises a plurality of particles, each having an SAP core surrounded by a fibrous layer to which an outer attachment layer is anchored. When applied to vegetation from an aircraft or ground vehicle, the attachment layer maintains the particle in contact with the vegetation. Concurrent or subsequent application of water hydrates the SAP, which is held proximate the vegetation and retards the fire. The SAP, fibrous layer, and/or attachment layer can be biodegradable. The fibrous layer can comprise coir. The attachment layer can comprise one or more naturally occurring plant materials, such as seed pods having an adhesive attachment feature and/or mechanical attachment features such as spikes or hooks. The disclosed fire-retardant material can be applied to mitigate an active, uncontrolled fire, or to vegetation on either side of a central region to contain an intentional fire within the central region, and thereby create a firebreak.

Foamable liquid compositions containing aqueous dispersions of cellulose nanocrystals and/or cellulose nanofibrils, nanoclay and surfactant are provided. The foamable liquid compositions provide stable foams useful in the protection of structures against the spread of fire.

A fire suppression system includes a first agent configured as a solid mass. The first agent includes at least one tetrazine-based compound. The at least one tetrazine-based compound comprises a majority by weight of the first agent. The first agent further includes a binder material, and additives. The fire suppression system also includes a circuit with an electrical power source and an initiator. The initiator is electrically connected to the electrical power source and connected to the first agent.

Disclosed herein are compositions comprising a super absorbent polymer (SAP) concentrate mixed with a long-term fire-retardant concentrate, prior to dilution with water, to form a mixed concentrate and methods of making such compositions. The mixed concentrate composition can be subsequently mixed with water to produce an aqueous fire-fighting solution.
