Mr. Osborne also designed the photo-recording transit for making panoramic records of forest conditions, as well as a collapsible water-bag knapsack for firefighting (patented in the US in 1935). Many fire finders were manufactured from 1920 through 1935, but the manufacturer, Leupold & Stevens, Inc., stopped production of replacement parts ...
Bromochlorodifluoromethane ( BCF ), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1]
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Fire retardant. A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. [ 1][ 2] Fire retardants may also cool the fuel through physical action or endothermic chemical reactions.
[1] Fire-retardant gels can also be slurries that are composed of a combination of water, starch, and clay. [2] Used as fire retardants, they can be used for structure protection and in direct-attack applications against wildfires. [3] [4] Fire-retardant gels are short-term fire suppressants typically applied with ground equipment. [5]
Modular Airborne FireFighting System. A MAFFS II-equipped C-130 Hercules from the 302nd Airlift Wing drops water over the Hayman Fire burn scar during training in May 2021. The Modular Airborne FireFighting System ( MAFFS) is a self-contained unit used for aerial firefighting that can be loaded onto both military cargo transport Lockheed C-130 ...
Standpipe (firefighting) A standpipe or riser is a type of rigid water piping which is built into multi-story buildings in a vertical position, or into bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water to the fire. Within the context of a building or bridge, a standpipe serves the same ...
Classes B:C for 1301 and smaller 1211 fire extinguishers (2.3 kg; under 9 lbs) and A:B:C for larger units (9–17 lb or 4.1–7.7 kg). Halon gases are banned from new production under the Montreal Protocol, as of January 1, 1994, as its properties contribute to ozone depletion and long atmospheric lifetime, usually 400 years.
