Skydrol is a brand name of fire-resistant hydraulic fluid [1] used in aviation and aerospace applications. It is a phosphate ester-based fluid that is known for its excellent fire resistance and ability to withstand extreme temperature and pressure conditions.
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.
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
A MAFFS-equipped Air National Guard C-130 Hercules drops fire retardant on wildfires in Southern California Red-dyed line of fire retardant stands out clearly on this Arizona hill, to control the Alambre Fire. Early fire retardants were mixtures of water and thickening agents, and later included borates [12] and ammonium phosphates. [citation ...
Substances with low combustibility may be selected for construction where the fire risk must be reduced, such as apartment buildings, houses, or offices. If combustible resources are used there is greater chance of fire accidents and deaths. Fire resistant substances are preferred for building materials and furnishings.
Depending on the fire conditions, applied fire retardant gels offer fire protection for periods of 6 to 36 hours. [11] After the retained water is completely evaporated from a gel, fire resistance is lost, but can be restored by re-wetting the surface if gel material is still adherent. [3]
Glauber's salt – sodium sulfate.Na 2 SO 4; Sal alembroth – salt composed of chlorides of ammonium and mercury.; Sal ammoniac – ammonium chloride.; Sal petrae (Med. Latin: "stone salt")/salt of petra/saltpetre/nitrate of potash – potassium nitrate, KNO 3, typically mined from covered dungheaps.
Typically, their undergarments beneath the heavier fire-resistant gear are made of flame-retardant cotton or another breathable, organic fabric that has been treated to resist ignition. [ 20 ] Polymers containing nitrogen , sodium , and phosphorus atoms can work as materials for fire-resistant cellulosic textiles, such as cotton or rayon .
