Are All Flame Resistant Fabrics the Same?

The simple answer? No!
Flame Resistant (FR) fabric is a fabric that will self extinguish when the source of the ignition is removed. It does not mean that the fabric is not flammable. When the flame or heat is in contact with the fabric, it will usually burn. However, it should not continue to burn when the heat or flame has been removed. There are basically two categories of flame resistant fabrics: treated and inherent.
