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 term fire-retardant as applied to organic (i.e., containing carbon) materials, is intended to refer to reduced fire hazard, as all will burn under certain circumstances. The tests used specified in building codes , such as NFPA 701, are more correctly flame resistance tests, which test a fabric's ability to resist ignition with the flame ...
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 .
Coprinellus domesticus, commonly known as the domestic inky cap, [2] or firerug inkcap, [3] is a species of mushroom in the family Psathyrellaceae.

The primary functions of a fireback are to protect the wall at the back of the fireplace and radiate heat from the fire into the room. The protection was especially important where the wall was constructed of insubstantial material such as daub (a mud and straw mixture coating interwoven wooden wattles), brick or soft stone.
An H-style cap (cowl) is a chimney top constructed from chimney pipes shaped like the letter H. It is an age-old method to regulate draft in situations where prevailing winds or turbulence cause downdraft and back-puffing. Although the H-cap has a distinctive advantage over most other downdraft caps, it fell out of favor because of its bulky looks.
For a fire to burn, all three elements of the fire triangle must be present: heat, fuel and oxygen. The fire blanket is used to cut off the oxygen supply to the fire, thereby putting it out. The fire blanket must be sealed closely to a solid surface around the fire. Fire blankets usually have two pull down tails visible from outside the packaging.
