A method of extinguishing or retarding fire can include disposing nano-clay onto the fire to retard or extinguish the fire. The nano-clay can be in the form of a powder. The powder can include nanoparticles having a particle size of about 1 nm to about 50 nm. The nano-clay can be used alone or mixed with water.

Implementations are disclosed herein that relate to a firefighting system. An example provides a firefighting system comprising a conveyance configured to receive and elevate screened soil, a chute configured to receive the screened soil at an entry point, and a nozzle configured to emit the screened soil toward a fire site, the nozzle comprising an augmentation device configured to increase a flow speed of the screened soil.

A fire-extinguishing equipment includes: a fire-extinguishing apparatus which transmits electromagnetic waves in a predetermined output direction and discharges an extinguishing agent; an electromagnetic wave-receiver which is provided in an fire extinguishing object and receives the electromagnetic waves; and a controller which controls the fire-extinguishing apparatus to start to discharge the extinguishing agent when the output direction is set to a direction of the fire extinguishing object and the electromagnetic wave-receiver receives the electromagnetic waves.

A fire suppression composition and method of encapsulation, thermal runaway prevention is provided. The fire suppression composition includes exfoliated vermiculite mixed with a liquid propellant, wherein the composition is chemical free, non-toxic, and biodegradable. Performance additives may be optionally added to improve the performance of the fire suppression composition. The fire suppression composition is intended for a variety of uses, and fire fighting systems. Although it may be used to fight a variety of fires, it is particularly useful for lithium ion battery fires. The exfoliated vermiculite is configured to encapsulate the object or substrate on fire, preventing thermal runaway and escalating fire situations.

An apparatus is disclosed for extinguishing a stovetop fire over a stovetop having a first burner, the apparatus including a container detachably mountable to a microwave positioned above the stove top, the container having a closure retained in a closed position on the container. A supply of fire suppressant material is retained within the container when the closure is in the closed position. A heat responsive actuator is disposed on the container. When the container is mounted to the microwave over the first burner, and the fire actuates the heat responsive actuator, the closure moves to an open position and at least a portion of the supply of fire suppressant material falls toward the first burner.

Battery enclosure arrangements for a vehicular battery system. The arrangements, capable of impact resistance include plurality of battery cells and a plurality of kinetic energy absorbing elements. The arrangements further include a frame configured to encase the plurality of the kinetic energy absorbing elements and the battery cells. In some arrangements the frame and/or the kinetic energy absorbing elements can be made of topologically interlocked materials.

Apparatus and method for firefighting includes a containerless core of a fire retardant material, compressed to form a prolate spheroid shape. A shaft with fins and a carrying hook can extend from the core tail. The core can have a core charge of an explosive material within the core channel. An altimeter sensor coupled to the core charge and a triggering mechanism is coupled between the altimeter sensor and the core charge, and causes the triggering mechanism to detonate the core charge when the apparatus reaches an altitude. A delivery apparatus is included with a frame having carry harness, and at least one holding hook on the frame coupled to the carrying hook. The carry harness supports delivery apparatus in transport. Powders of calcium carbonate, magnesium carbonate, ammonium sulfate, diammonium sulfate, diammonium phosphate, ammonium polyphosphate, or monoammonium phosphate can be intermixed as fire retardant, along with indigenous plant seed.

An electric wire connector having fire-extinguishing function includes: a protective holder (100) comprising a conductor cap (120) and an insulator gap (140), wherein the conductor cap (120) accommodates a conductor part 12 of an electric wire connection part (10), wherein the insulator cap (140) wherein the insulator cap (140) has an inner diameter larger than an inner diameter of the conductor cap (120) and accommodates an insulator part (14) of the connection part (10); a metal tube (200) installed within the conductor cap (120) and press-fits in the conductor part (12); and a fire-extinguishing module (300) installed in the insulator cap (140) and having a fire-extinguishing tunnel (302), wherein the fire-extinguishing tunnel (302) is provided in the insulator cap (140), wherein the insulator part (14) is inserted in the fire-extinguishing tunnel, wherein the fire-extinguishing powder is ejected in response to a heat of a fire.

An apparatus is disclosed for extinguishing a stovetop fire over a stovetop having a first burner, the apparatus including a container detachably mountable to a microwave positioned above the stove top. A supply of fire suppressant material is retained within the container. A heat responsive actuator is disposed on the container. When the container is mounted to the microwave over the first burner, and the fire actuates the heat responsive actuator, at least a portion of the supply of fire suppressant material falls from the container toward the first burner.

An apparatus for extinguishing a stovetop fire including a microwave positioned above the stove top, a compartment defined in the microwave; and a closure retained in a closed position on the microwave. A projection member is positioned within the compartment, the projection member retained in a retracted position while the closure is in the closed position. A supply of fire suppressant material is retained within the compartment when the closure is in the closed position, the supply of fire suppressant material including a second burner portion positioned against the projection member. A heat responsive actuator is disposed on the microwave. When the microwave is positioned over a first burner on the stovetop, and the fire actuates the heat responsive actuator, the closure moves to an open position and the projection member moves to an extended position, the projection member forcing the second burner portion toward a second burner.
