FIRE RETARDANT
To be considered fire retardant or flame resistant, a fabric must self extinguish when ignition is removed. There are 2 types of fabric classifications.
CHEMICALLY TREATED FLAME / FIRE RETARDANT
INHERENT FIRE Inherent fabrics are made from non- flammable/flame resistant materials that are woven or knitted into their fabric structures.
Fabrics that are chemically treated with a fire retardant chemical to slow down burning or self-extinguishing when exposed to flame.
PERSONAL PROTECTIVE CATEGORY (PPE) Personal Protective Equipment Category (PPE) are categories that are specified in the NFPA 70E Electrical Arc Flash guidelines. PPE 1 Clothing required to meet a minimum Arc rating of 4 Cal /cm 2 PPE 2 Clothing required to meet a minimum Arc rating of 8 Cal /cm 2 PPE 3 Clothing required to meet a minimum Arc rating of 25 Cal /cm 2 PPE 4 Clothing required to meet a minimum Arc rating of 40 Cal /cm 2
ARC RATING Arc Thermal Performance Value (ATPV) defines the protection level against second and third degree burns (Arc Flash). The higher the number, the greater protection provided.
