Because of ferrocerium's ability to ignite in adverse conditions, rods of ferrocerium (also called ferro rods, spark rods, and flint-spark-lighters [1]) are commonly used as an emergency firelighting device in survival kits. [2] The ferrocerium is referred to as a "flint" in this case, as both are used in fire lighting.
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.
However, natural cotton fabric is flammable and will rapidly burn. This drawback limits the use of cotton fabrics. [18] Therefore, treating cotton fabrics to obtain a fire-resistant fabric is important. [19] Firefighters, or those exposed to flames on a regular basis, rely on flame-retardant cotton for both protection and comfort.
The vibrant red fire retardant is known as Phos-Chek and has been used by firefighters battling wildland blazes for over 50 years, according to its manufacturer, Perimeter Solutions.
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 ...

In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame. The degree of flammability in air depends largely upon the volatility of the material – this is related to its composition-specific vapour pressure , which is temperature dependent.
