A method of proactively protecting property and buildings constructed thereon from wild fire by spraying environmentally-clean anti-fire (AF) chemical liquid prior to the arrival of wild fires. Intelligence data is remotely collected relating to risks of wild fires in specified regions, and maintained in a network database, and used to generate anti-fire (AF) spray protection maps and task reports for execution in the specified region. Prior to the arrival of a wild fire to the region, and based on the GPS-specified anti-fire (AF) spray protection maps and task reports, application servers deployed on a wireless system network issue a request or order to the property owner, or its registered contractor, to apply clean AF chemical liquid spray on the GPS-specified parcel of property using a GPS-specified AF chemical liquid spraying system, so as to proactively protect the property prior to presence of wild fire.

Systems and methods are described for securely monitoring a shipping container for an environmental anomaly using elements of a wireless node network of sensor-based ID nodes disposed within the container and a command node associated with the container. The method has the command node identifying which of the ID nodes are confirmed as trusted sensors based upon a security credential specific to each of the ID nodes; monitoring only the confirmed ID nodes for sensor data broadcast those ID nodes; detecting the anomaly based upon the sensor data from at least one of the confirmed ID nodes; automatically generating an alert notification related to the detected environmental anomaly for the shipping container; and transmitting the alert notification to the external transceiver to initiate a mediation response related to the detected environmental anomaly.

The invention generally encompasses fire suppressant compositions and methods. In certain embodiments, the composition is configured to the heating device, for example, a stove or microwave. In certain embodiments, the invention includes holes to allow heat to enter into a compartment/shell and impinge upon a pressurized pouch containing a suppressant agent. In other embodiments, when a fire occurs it causes an exterior layer or relief valve to rupture the suppressant agent discharging towards the heat source and extinguishing the fire. In another application this complication is connected to an electrical or gas system and cuts the supply when the exterior layer of the device ruptures and releases a suppressant.

A fire protection sprinkler system includes a horizontal barrier that covers two adjacent racks, and the vertical flue space between the racks. The horizontal barrier is provided at a predetermined height, and has a width that is at least equal to a width of the rack, and a depth that is at least equal to a sum of a depth of the rack, a depth of the other rack, and a depth of the vertical flue space. In addition, the horizontal barrier can be a sheet having one or more apertures. The system also includes a rack level fire protection sprinkler connected to a fluid supply conduit, and being disposed in the vertical flue space below the horizontal barrier. The rack level sprinkler has a K-factor of 11.2 gpm/(psi).sup.½ or greater, and is vertically spaced from commodities stored on the rack and the other rack covered by the horizontal barrier.

The portable fire extinguisher comprises a housing (10) with a wall, an extinguishant unit (12) containing an extinguishing agent within the housing, a temperature-responsive extinguishant unit activator (14), and at least one extinguishing agent discharge pipe (16) leading from the inside of the housing to the outside of the housing. An activator is inside the housing and the housing has a flow channel for conducting external air to the activator. In the event of a fire, the temperature of the air outside the housing rises and the heated air is connected via the flow channel to the activator, which triggers the fire extinguisher.

A system is provided for rapidly cooling a pot or boiler. The system includes a cylindrical or semi-cylindrical tube operatively connected to the pot or boiler. The tube also includes a means for attaching a water source or hose. Finally, the tube may also include a series of holes or nozzles for directing a stream or spray of water towards the outer surface of the pot or boiler. The system may be built into the pot or boiler or may be a standalone, removable and adjustable system for use on multiple different pots or boilers.

System and methods to provide ceiling-only suppression fire protection of up to fifty feet (50 ft.) of rack storage of cartoned unexpanded plastic commodities and less hazardous commodities, such as for example, Class 1, Class 2, Class 3, Class 4 and/or combinations thereof beneath a ceiling having a maximum ceiling height up to fifty-five feet (55 ft.). The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote sprinklers spaced at a preferred sprinkler-to-sprinkler spacing of eight to ten feet (8-10 ft.) coupled to two to four branch lines tied to a common cross main supply pipe of firefighting fluid.

A container holding a fire suppressing powder has a top, a cylindrical sidewall and a bottom with a hole, the bottom having a score line defining a segment. An explosive material housing containing an explosive material is mounted to a head of a mounting member. The mounting member has a lower portion smaller in cross-sectional dimension than the head, depending downward from the head and extending through the hole in the bottom. A retainer is secured around the lower portion of the mounting member below the bottom to secure the mounting member to the bottom. A fuse extends through the hole in the bottom, a passage in the mounting member, and into the explosive material housing. A plate is mounted within the container a selected distance below the top, the plate being movable a short distance toward and away from the top in response to ignition of the explosive material.

Antifreezes, which include glycerol or a mixture of alkylene glycol and glycerol, water and an organic acid salt, are provided. Exemplary antifreezes include at least about 45 vol. % water, greater than 48 to about 55 vol. % glycerol, 0.1 to 1.75 wt. % of a salt of an organic acid having one or more carboxylic acid groups, and optionally, one or more buffers. Wet sprinkler systems containing the antifreeze, methods of controlling a fire using the antifreeze and methods of preventing a wet sprinkler system from freezing are also provided.

A storage system comprising a portable building having a climate-controlled interior space and a plurality of hazardous materials storage cabinets disposed in the interior space. The portable building contains no water sprinklers and no smoke detectors and has a floor that is sealed to prevent leakage of liquid. Each cabinet comprises metal double walls separated by an air space and a liquid-tight containment sump. Each cabinet is configured so that fire cannot spread from a space above a shelf to a space below the shelf. The storage system further comprises an electrical power connection and an HVAC unit mounted to an exterior of the portable building.
