There are 2 categories of flame-resistant fabrics. One is FR-treated, where the fabric is treated with FR chemicals that bond deeply into it. The other is inherent FR fabrics, which are made of fibres that are already made flame-resistant.
Flame-Resistant clothing is made from material that is inherently resistant to flames and embers. Meaning that the threads and fibers will naturally self-extinguish.
Flame-Resistant Fabrics are made up of typically synthetic fibers that resist ignition under prolonged exposure to flame or heat. The degree of inherently flame-resistant

Flame-resistant (FR) clothing is a type of personal protective equipment (PPE) designed to self-extinguish upon ignition. Though FR clothing can still catch fire, these garments will not continue to burn and effectively reduce the risk and severity of burns.
The EN certification of Treated fabrics can be just the same as Inherent fabrics and can include IEC 61482 Protective Clothing against the Thermal Hazards of an Electric Arc or EN ISO 11612 Heat & Flame Protective Clothing. FR- treated fabrics have a very good level of protection against molten metal, heat, and ARC.
The term ‘Inherent’ is used to describe a fabric whose Flame-Resntant properties are permanent and cannot be removed. The most common FR fibres used in protective clothing are modacrylics and aramids. These fibers provide excellent protection against flames and heat.
