A blanket for fighting grass and scrub fires along a fire line includes a sheet of fire resistant material forming a lattice with multiple openings. The openings vary in size from larger openings along the sheet's front edge to smaller openings at the sheet's back edge, and vary in size across the lattice to form parabolic-shaped burn zones that separate a fire burning into the blanket, dissipating its energy. The blanket is a rectangular sheet of woven fire resistant fiberglass strips coated in vermiculite and is flexible for rolling, with connectors securing the woven strips together at points of overlap. The sheet can be placed atop or near grass or scrub at risk of burning, arranged with the front edge toward the fire and the back edge away from the fire. Once the burning risk passes, the sheet or sheets may be removed and rolled up for storage or transport.

A method for extinguishing fires which includes the following phases: a first phase wherein a projectile of compact crushed ice is produced, with a volume between 0.5 liters and 2 liters, a second phase wherein the projectile is placed on a shuttle that fires it over the area in flames to be put out, and a third phase wherein successive projectiles are launched until a shower of compact crushed ice projectiles is formed with at least 30 liters per square meter per hour. A projectile for extinguishing fires is also disclosed.

An apparatus for extinguishing a stovetop fire 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 projection member is connected to the container, the projection member retained in a retracted while the closure is in the closed position. A supply of fire suppressant material is retained within the container 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 container. When the container is mounted to the microwave over a first burner, 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 the second burner.

A fire suppression module. The fire suppression module includes a base member, a cap member and a fire suppressant. The cap member is connected to the base member. The base member and the cap member cooperate to form a an enclosure. The fire suppressant is positioned within the enclosure.

An apparatus for extinguishing a fire on a stovetop, the apparatus including a container detachably mountable to a microwave positioned above the stove top, the container having a closure movable between an open and closed position on the container. A projection member is connected to the container, the projection member movable with respect to the container between a retracted and extended position. A supply of fire suppressant material is retainable 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 a first burner, and the fire on the stovetop actuates the heat responsive actuator, the closure moves to the open position and the projection member moves to the extended position, the projection member forcing a second burner portion of the supply of fire suppressant material toward the second burner.

The blanket is a rectangular sheet of woven fire resistant fiberglass strips coated in vermiculite and is flexible for rolling, with connectors securing the woven strips together at points of overlap. The sheet can be placed atop or near grass or scrub at risk of burning, arranged with the front edge toward the fire and the back edge away from the fire. Once the burning risk passes, the sheet or sheets may be removed and rolled up for storage or transport.

An assembly for detecting agglomeration of a powder for a fire suppression system includes a vessel configured to contain a powder and a compressed gas and a plurality of piezoelectric sensors disposed in the vessel. At least one sensor of the plurality of sensors is disposed at an interface of the powder and the compressed gas when the vessel is in a filled state.

This patent is about fighting House/Apartment/Condo/Building fires by using Dry Ice and/or Carbon Dioxide Gas. By the time people call the authorities, the fire has grown so big that it is difficult to control or to extinguish by ordinary fire fighting techniques. Traditional house fire fighting is to spray water into the house so that the flames would disappear and stop burning. This patent involves two methods: 1) throwing, spraying or spreading powder or flakes or pellets of Dry Ice on or near the fire or around the fire so that the Carbon Dioxide sublimating from it diffuses and expands to get to the fire or to fill up the house or around the house so that Oxygen cannot get into the fire to continue burning; 2) spraying Carbon Dioxide gas into the house, apartment or building to bring down the Oxygen level to stop the fire.

The disclosure relates to an explosion suppression system and associated methods, which may include a cannon comprising a barrel and a propellant tank, a suppressant cartridge configured to be inserted into the barrel, and a triggering mechanism positioned between the barrel and propellant tank. The suppressant cartridge may be configured to operatively engage with a propellant source. One or more explosion sensors, which may be of different types, may be included in a system, and an explosion suppression device may be configured to activate when one or more of the sensors indicate an explosion. The disclosure further relates to a lock-out mechanism for an explosion suppression system, with the lock-out mechanism including a mechanical and/or electrical component. In one embodiment, an actuator may be positioned between a suppressant agent volume and a propellant agent volume of an explosion suppression system.
