Flame resistant clothing will not provide significant protection from burn injury in the immediate area of contact with the ignition source. However, flame-resistant garments do provide protection against clothing ignition and sustained flame spread.

However, flame resistant garments should be immediately removed and replaced with clean FR apparel if they become fouled with flammable material. If laundering or dry cleaning cannot remove flammable contaminants, the contaminated garments should be completely removed from service.

Proper cleaning and maintenance of any flame-resistant garment is essential to remove potentially hazardous soils and avoid a build up of materials that could mask performance. This includes flammable soils and greases as well as other contaminants such as build up of hard water ions that can coat fibers with flammable material.
Always follow garment manufacturer’s care label recommendations and other published instructions or recommendations.
