The present invention provides a fire extinguishing sheet suitable for productivity, mass production, and large-scale production, wherein the fire extinguishing sheet can be used in places, facilities, structures, etc., where a fire may occur, and has an initial fire extinguishing function. The fire extinguishing sheet according to the present invention contains a fire extinguishing agent that when a predetermined temperature is reached, thermally decomposes to generate a fire extinguishing component.

A fire suppression composition includes starch, a pseudo-plastic, high yield, suspending agent, paraffin or olefin, and a neutralizer.

This relates to apparatus that can form dilute aqueous firefighting compositions from an aqueous concentrate.

Some embodiments disclosed herein pertain to compositions for extinguishing or suppressing fires, systems for using the same, methods of making compositions for extinguishing or suppressing fires, and/or methods of using the same. In some embodiments, the compositions disclosed herein are suitable for use on Class D fires (e.g., suppressing or extinguishing the fires). In some embodiments, the compositions disclosed herein comprise a botanical material. In some embodiments, the compositions lack sugar alcohols and/or halogenated compounds.

A fire stopper includes a fire extinguishing agent-containing layer and a resin substrate arranged in this order.

The present application provides water-enhancing, fire-suppressing hydrogels that are formulated to minimize toxicity and negative environmental impact. The present application provides a composition comprising: (i) at least one thickening agent; (ii) at least one liquid medium; and, optionally, (iii) one or more suspending agents, wherein the composition consists of >75%, by weight, consumer-grade components and wherein the composition is a concentrate that can be mixed with water or an aqueous solution to form a fire-suppressing, water-enhancing hydrogel. Each of the at least one thickening agent, suspending agent and liquid medium can be non-toxic and biodegradable. Also provided are the fire-suppressing, water-enhancing hydrogel and methods of production and use thereof during fire fighting or fire prevention.

The present invention provides moldable, fully scalable cellulose silica-based hydrogels for use as low-cost and safe carriers and aqueous viscosity modifiers in various industrial and medical applications.

Systems and compositions for suppressing and extinguishing several classes of fire, e.g. Class D, fires are disclosed. The composition includes some form of powdered Aloe vera, a bio-surfactant, a thickening agent, and a diol. The composition may be mixed with paint to coat a structure thus protecting the structure from fire. The composition may also be mixed with epoxy resin for coating a structure also for fire protection. The composition may also be in the form of a gel in canisters for extinguishing fire.

A dispensing unit that consists of two or more dispensing solutions, at least one being a fluorine-free foam solution, and at least one hydrogel-based solution, and which involves the dispensing of each solution through one or more compressed air foam system (CAFS), where the CAFS may use compressed air, nitrogen, or other inert gas. The individual solutions may be mixed prior to the CAFS, or one or more solutions mixed after the CAFS, or they may be mixed in separate CAFS chambers. The resulting foam may be dispensed through a single line or through multiple lines, applied simultaneously and/or at different times, and may be controlled manually and/or through automatic controls, or through a combination of the above.

The present invention discloses a fire extinguishing sheet which is used in places, facilities, devices, tools, structures and the like where a fire may break out, and which makes initial fire extinguishing possible. This fire extinguishing sheet contains at least a potassium compound as a fire extinguishing chemical that is thermally decomposed upon reaching a predetermined temperature and generates a fire extinguishing component; and this fire extinguishing sheet is arranged in places, facilities, devices, tools, structures and the like where a fire may break out. If a fire breaks out, aerosols containing potassium radicals (a potassium compound) are generated from the fire extinguishing sheet, and the chain of combustion is interrupted by a negative catalytic effect, thereby quickly extinguishing or suppressing the fire.
