Re: what is a fire blanket made of?

Fire blankets are made of many materials. Two of the most common are made 
from fiber glass like fabric which can be woven into a supple or pliable 
type of material to allow the blanket to conform to many differing shapes, 
sizes. Some are 100% fiberglass. Others are made of nomex, the same type 
of material which firefighters' protective clothing is made from. Nomex is 
a dupont product and also a dupont trade mark. It is a tightly woven 
canvass like material which is saturated by fire retardant chemicals. 
Underneath this arrangement is much insulation which allows firefighters 
to go into burning structures and get close enought to the seat of the 
fire to effectively extinguish the flames. It is not totally fire proof 
and will burn if exposed to high heat for prolonged periods, but most 
firefighters find it uncomfortable to stay that close to the fire for a 
long enough time to allow it to burn. Hope this helps you with your query.

Thanks,

This is not to say that it will not burn at all but has a great amount of 
trouble getting itself to sustain a combustible chain reaction, of which 
fire is made.
